News from South Korea leads on the wires at year's end


Kori Nuclear Plant, South Korea - courtesy KHNP

Anyone reading the news over the last week -- international news, that is -- has seen stories here and there on the hacking of Korea Hydro & Nuclear Power in South Korea.  On one particular day, I noticed almost 250 stories about this topic listed by Google's news search.  There is much hyperbole going around, very little fact, and frankly no positive official resolution as of yet.

Events

Here's what we know.  On December 9, a number of emails were sent to various personnel at KHNP in administrative capacities which were addressed from well known but retired former nuclear industry members.  These accounts had in fact been hacked.  The emails contained a malware package that then downloaded itself onto the computer being used, and after arranging for information to be sent out set a timer to destroy the hard drive with only a black screen showing the phrase "Who Am I?" left visible.  The hack accessed a number of what might be called proprietary drawings and plans for KHNP nuclear plants (not the newest, so far as is known) as well as reactor core accident analysis models (these are computer programs or codes) or perhaps just the guides for these, as well as personal data of thousands of KHNP and/or KEPCO (Korea Electric Power Company) employees.

The hacker(s) threatened to destroy by meltdown three specific reactors in South Korea if they were not shut down by Christmas.  The hacker(s) did offer the return of the stolen materials but did so with the request for money.  The group said to be behind this is an anti-nuclear group in Hawaii; the actual perpetrators may be in the U.S. or China or both.

Here's the important fact everyone needs to know:  The hackers, even with the apparent high level of skill used in these attacks, cannot access by internet or radio or short wave or any other interactive means any of the control and monitoring equipment for the nuclear reactors.

Or any nuclear reactors.

Anywhere.

The plain fact of this has been repeated time and again by insiders over this week, by KHNP itself, and in a Forbes article by James Conca.  So what's the big deal?  Why, over the last 48 hours, were three plants there surrounded by armed troops?  Why did KHNP / KEPCO perform a two day series of cyberattack drills simulating events occurring to the reactor instrumentation and control requiring manual intervention?

There's only one word for this - and that word is "Preparation."  This is the first time that cyber-war has been specifically targeted in this way against power reactors in South Korea, and since there is apparent high skill on the part of the hackers, no one was about to take the specific, targeted threat lightly. 

The thing to know here is that the computers that were hacked had, or had access to (on mainframe) administrative items.  People's HR info; plant drawings one might use for training or planning; accident analysis codes used both for training and for actual simulation of, say, new fuels; guides for operating various pieces of equipment.  This is like breaking into the trailer of a semi-truck and threatening to disable the engine.  It's part of the truck that was broken into, all right -- but not the cab.  Which isn't accessible via the trailer anyway. 

You still guard the truck.  The WHOLE truck.

Resolution awaits

The final resolution of this act may end up taking a long time.  Attempts involving the FBI in the US and requests for help to China have resulted in scanty details as the hackers are chased across the cyber world, having expertly covered their tracks by using multiple IP addresses.  It may not be known for years -- or maybe, never known -- who actually did this, even if the organization behind it has at least been labeled ("Who Am I" in Hawaii, it's thought.) 

The key of course here is that persons should not open emails with files unless they're expecting those files.  All computers at any plant should have anti-virus running at all times, with appropriate security settings.  Those computers should be firewalled from any plant information if they're on the net. 

Hollywood - right on time, oddly, again

Now, just as this all hits the fan we see coming out a new cyber-combat-war-intrigue movie called "Blackhat," in which hackers supposedly not only hack but control and then melt down and then cause to explode (we're not yet clear on all this) a reactor or two in Taiwan.  Some details.

•There are nuclear plants in Taiwan.
•Their instrumentation and control is not on the net either.
•Unless there's a massive inside job, this isn't any more possible than in South Korea.

The ONLY way this can happen is with an inside job, and something like the whole STUXNET debacle happening.  Believe me though - those lessons were learned.

And we must remember -- the explosions that happened at Fukushima Daiichi Units 1 and 3 (and secondarily at Unit 4) were caused by hydrogen and perhaps carbon monoxide combustion as a result of the core damage to the reactors.  These were NOT explosions of the reactors - the buildings exploded because they were filled with combustible gases.

Now, no one can say that these types of events such as Fukushima Daiichi CAN'T happen (this is why we have such elaborate containment in the first place -- and note that at Three Mile Island, the same thing happened but not no damage occurred because of the completely different containment building design) but we will have to wait and see what this movie is actually saying was done.

Ah, and there was that name -- Three Mile Island.  You know, the accident that occurred right around the time the movie "The China Syndrome" came out?  (Some people think this is no coincidence;  I disagree, but the timing could not have been more striking.)  Now we have this event of cyber threat and right at the same time a movie on the way about it.  Does Hollywood mirror events, or do events follow Hollywood?  Not sinister; just interesting.

Good news

There was a piece of good news that came out of South Korea, but because of the frenzy over the hacking job, it was missed or skipped.  On December 23, KHNP submitted documents to the US Nuclear Regulatory Commission to get the Design Certification for the APR1400 back moving in the United States.  This reinvigorates a process that NRC had halted in December 2013 when it rejected the Design Certification Application from KHNP citing incomplete information.  So, as I reported earlier this year for the American Nuclear Society, it still looks as if the next design to be certified in the US will probably be the APR1400 - which will be a major feather in the cap for KHNP and is considered an icebreaker to further export of the design worldwide.

Last day to comment on EPA Clean Power Rule

Today, December 1, is the last day to comment on the Environmental Protection Agency's proposed Clean Power Rule.

This rule is detrimental - unfair, that is - to nuclear energy for two reasons:

•The rule does not credit present nuclear generation the way it credits renewables
•The rule does not credit nuclear plants presently under construction but not yet completed as contributing in the future to carbon emission reduction.

MAKE YOUR COMMENT TODAY....  I did!  The comments are open until 11:59 PM Eastern Daylight Time.

Click here to reach the EPA page for commenting on the Clean Power Rule.

The American Nuclear Society (of which I'm a member) has come out, not surprisingly, against the rule.  Read more about the ANS position on the rule by clicking here.

NRA finds fault under JAPC Tsuruga NPP "recently active"

A report today is out that the Nuclear Regulation Authority in Japan has received report from an independent expert panel that faults near and under Japan Atomic Power Company's Tsuruga Nuclear Plant may be considered active.

Debate has gone back and forth between the NRA and JAPC about the most recent active dates for faults near the plant.  An NRA panel found likelihood of activity near or under Unit 2 at the plant in May of 2013, after which JAPCo convened its own study to counter the NRA report.

An English summary of the June 2014 "Second Review" by JAPC can be found here.

Now, the NRA has returned to yet again counter JAPC with a further report.  The uptake from this is that if JAPC cannot prove to the NRA that the faults near the nuclear plant haven't been active in a VERY long time, i.e. 120,000 to 130,000 years, and cannot move, then JAPC may be forced to decommission the Tsuruga NPP.

Located at Tsuruga are two units - of course long since shut down, along with all other Japanese nuclear plants.  Tsuruga Unit 1 is a Boiling Water Reactor that went into service in 1970, while Unit 2 is a Pressurized Water Reactor which went into operation in 1987.  Preparations were underway at the site to construct two more units, which were to have been Mitsubishi APWR units but that construction has been deferred indefinitely.

Neither of these units at Tsuruga have applied to the NRA for restart examination; JAPCo's only operative unit on the opposite coast (the East coast of Japan) from Tsuruga, which is Tokai No. 2 has applied for restart and should the decommissioning of the units at Tsuruga be necessary Tokai No. 2 would be JAPC's only remaining operational unit.

Should this finding of seismic activity be upheld, Tsuruga would be the first NPP in Japan forced to decommission on seismic grounds following the Fukushima Daiichi accident.

Goodbye, Harry Reid; Hello, Yucca Mountain?

... well, goodbye as Majority Leader in the Senate, anyway.  The house of cards that Reid built - predicated upon supposed safety issues with Yucca Mountain - has fallen.

•Jaczko, Reid's hand-picked slave servant, is long gone from the NRC Chairmanship and has been clearly recognized for what he is -- solidly anti-nuclear.

•The NRC Staff has released Volume 3 of the SER for Yucca Mountain, saying that it's safe to use as a long term geologic repository for spent nuclear fuel.

•Macfarlane, chosen to succeed Jaczko and who is on the record as being against Yucca Mountain, has vacated her position -- likely because there's no scientific support to say it's unsafe, and because there's no political support for that position to be held.

•Reid, the anti-Yucca Majority Leader, cannot hold that job any more after the mid-term election results last night.

NEI Nuclear Notes has just published a great, short piece introducing us to this new world that might have just a bit less anti-nuclear rhetoric and a bit less decision making without knowledge.  You can find that new piece by clicking here.  Alex Flint does a great job of beginning to crack open the door on what the new world may look like - at least for the next two years.

Note his mention of Barbara Boxer.

Folks who are pro-nuclear have good reason to be happy this morning.

Multiple Parties Rush to Restore Doel 4

I've reported quite a bit here (and at ANS Nuclear Cafe) on the ongoing investigation concerning perceived reactor vessel flaws at two Belgian nuclear plants.  While that's ongoing, a recent event saw apparent deliberate action to dump turbine lube oil from Doel 4's turbine generator while it was at full load, causing extensive damage.

At this time, two well known turbine generator manufacturers are working to restore the machine - Alstom is performing work on the high pressure turbine, while Siemens is working on the low pressure turbines.  It's hoped that the plant can be back on line before the new year.

Here's the statement at the time of the incident from FANC, the Belgian nuclear regulator:

FANC investigates on automatic shutdown of Doel 4 NPP
8 August 2014 - The Doel 4 nuclear power plant was automatically shut down on Tuesday 5 August 2014, as a result of an oil leak on the steam turbine. This turbine is located in the non nuclear part of the NPP. A FANC expert team went to the site to make the necessary assessments.

Its conclusion is that this oil leak probably resulted from a voluntary manual intervention. Further investigation should reveal the precise circumstances behind this event. Meanwhile, the FANC has already taken additional action to ensure the safety and security of the nuclear installations.

After the automatic reactor shutdown, it appeared that one of the three auxiliary feedwater pumps was unavailable due to a technical problem. However, the reactor was shut down in safe condition with no other problem. After investigation, this anomaly was rated as level 1 on the INES scale.

This incident had no impact neither on the safety of the workers and population, nor on the environment.

Where is Will, and by the way, Pakistan might be crazy

Some of you might have noticed a distinct reduction in posting here.  That's because for about a month I've been handling all social media for the American Nuclear Society, in the wake of some shaking up at headquarters, in addition to being in on a number of other projects.  So I've been quite busy actually -- it's just that everything has been coming out under the ANS brand.

I've also made the decision to launch a local, Ohio initiative that looks at energy more broadly than just all-nuclear all-the-time, and which will engage (hopefully) some of the local interests here on all sides.  You'll see more of that later.

••••••••••

For now, as I scan the headlines / Facebook posts / Twitterverse for news items today, I run across this little gem:

"Pakistan court stops construction work on nuclear power plants."

Now, the basic premise here is this:  Since the vendor for the proposed nuclear plants in Karachi, which is CNNC or China National Nuclear Corporation, has never built and operated the particular model of nuclear plant slated for this project (the ACP-1000) then the court believes that the environmental assessment is invalid.  This order was issued after receipt of a petition by an environmentalist group (I use that term very loosely indeed) who had made the case for this finding.

The Chinese must believe that Pakistan has some problems - I would.  After all, it's in China that the first-ever Westinghouse AP1000 plants are being built.  In other words, China is the location for a true FOAK (First Of A Kind) nuclear plant not indigenous to China.  On the other hand, it's not really perfectly correct to say that the CNNC ACP1000 is something totally new, out of left field.  That plant derives from over 30 years of work by CNNC in developing indigenous nuclear plant technology.

The ACP1000 nuclear plant is described as GENIII+ by its vendor; the NSSS (Nuclear Steam Supply System) was developed in concert with Westinghouse and Framatome (AREVA now) and is a three loop pressurized water design, very much like designs marketed and built for decades by Westinghouse, and then by its other licensees, again such as Framatome/AREVA (who have extrapolated and advanced designs beyond the 'break' with Westinghouse.)  The overall power plant isn't a totally clean sheet of paper sort of thing, but rather a design developed from decades of experience in Chinese nuclear plants.  CNNC lists in its sales brochure the following points of interest to any discussion of the declaration of "unproven effect" by the Pakistani court:

•  ACP1000 is designed using structures, systems and components already proven in China in existing NPP's (Nuclear Power Plants)
•  Structures, systems and components of new or recent design are acceptable and satisfactory operation can be demonstrated for conditions similar to that of new (existing) plants
•  Extrapolation of the design, size, capacity, duty, etc. of proven structures, systems and components to ACP1000 are reasonable
•  Safety structures, systems and components have been thoroughly tested and approved by the Chinese safety authority (NNSA.)

So it appears then as if the Pakistani court will have to either decide, or defer to other authority, whether or not this new plant design is so far off base compared to existing practice that its safety cannot be assured.

(SPOILER ALERT:  It's not that far off.)

Given this kind of finding (which might indeed just be a temporary holdup for a week or two... but one never knows) one might wonder if the vendors might have to assess whether or not to offer designs for export that are already operating instead of which merely are design certified and/or under construction.  Were this the case, let's say, with the UAE and its Barakah plant, then the South Koreans would not be building the advanced APR1400 plants there but rather the older OPR1000 or perhaps the updated OPR1000+ plants.  And yet again it's hard to offer 'last year's model' in the competitive export world.   

We shall wait and see.

Enough of that - back to work I go!

Nuclear Risk Research Center

Japan's Central Electric Research Institute of Electric Power Industry, an entity that serves all of the utilities in Japan, has created a subsidiary Nuclear Risk Research Center, whose website launched today.

Dr. George Apostolakis, a former Commissioner at the US NRC, is heading this effort.

See the website at this link.  I will also add a link into the "Fukushima Accident Reports" stand-alone page on this site, since it's very clear that the development of this entity is a direct result of the accident and perceived need to change how we analyze events.

Fukushima Daiichi links, facts; Japan nuclear guide

Just a couple items relative to Fukushima Daiichi....

•I've updated my Fukushima Accident Page with links to the most recent analysis of "unexplained events" during the accident, as developed by TEPCO.  There are, and continue to be, a number of unexplained phenomena during the accident that TEPCO is striving to deciper, and this body of work addresses those most important to progress in both decommissioning and overall analysis.  It's significant to note that the amount of fuel damage estimated in all three reactors continues, once again, to slowly increase over time.  Some might recall early estimates / statements by TEPCO that major fuel damage had occurred in all three units, which was then backed away from; reports by TEPCO at the ANS Winter Meeting I attended two years ago began then to intimate more severe damage.  This present report essentially duplicates the developed results I heard at that meeting.

TEPCO has decided to scrap the AREVA produced decontamination system at Fukushima Daiichi, which sat unused for essentially three years.  This event has gone practically unnoticed in nuclear press.  The cost of the equipment has not been revealed, and apparently isn't open for discussion.

And relative to Japan in general...

•It's no secret that all nuclear utilities in Japan have applied to restart at least one reactor each, and it's also no secret that Japan is actively trying to export nuclear energy in order to help its economy.  In light of that, it's interesting that the Japan Atomic Industrial Forum has published an all-new "Nuclear Energy Buyers Guide in Japan" volume, which is available for free on the net.  Click here to get this document, which has a great wealth of information in both graphic and tabular form.

APR+ Design Certification Announced


While discussion has been focused on the announcement that the ESBWR was approaching design certification in the United States, another, completely different reactor plant type has actually achieved its design certification without any news coverage of note whatsoever.

On August 14, 2014, the APR+ nuclear plant design received official type certification in South Korea after a rigorous seven year development process.  The design is a two loop PWR rated 1500 MWe, with a designed plant life of 60 years and a core damage frequency an entire order of magnitude lower than that calculated for the APR1400 design that it supplants.  As initially designed the plant has a station blackout coping time with no action of eight hours; severe accident management design for the plant is intended to guarantee in-vessel retention of the core in any accident.  Four safety injection trains as well as passive devices combine with a semi-modular construction design, giving South Korea a world class nuclear plant in the upper range of nuclear plant outputs with an intended eventual construction time of 36 months.  Increased safety and reduced unplanned shutdowns are said to be hallmarks of the new APR+ design as compared with the previous designs.

APR+ also has a number of design concessions to load following on a daily schedule; the initial concept is for load change to be automatically controlled within a band of 50% to 100% power with no operator action at all.

The APR+ is a developed version of the still fairly recent APR1400.  The APR1400 type's construction began in 2011 and has ten units under construction presently in both South Korea (six units total) and the UAE (four units.)  It is expected that orders for new commercial nuclear units in the future in South Korea will be for APR+ units, replacing the APR1400. 

News of the official design certification of the APR+ by South Korea's Nuclear Safety and Security Commission is only the most recent coup for this nation's nuclear enterprise; of much note just two years ago, that is on July 4th, 2012 was the announcement that the SMART SMR had received the world's first design certification for any iPWR SMR design.  It's clear that KHNP and the entire South Korean nuclear establishment are pushing ahead aggressively in development (and marketing) and that, for the moment, that nation appears to have the lead in certifying new designs.  What now awaits is the first actual order for either type.

Doel 3 and Tihange 2 units back in news / Turbine Generators

The saga of the hydrogen inclusions in the reactor vessels of the Doel Unit 3 and Tihange Unit 2 reactors in Belgium has, as some may already know, taken another turn; a recent finding has caused the shutdown of these two reactors indefinitely pending results of yet another investigation.

The history of these events is roughly as follows:  First, during an inspection in which new and sophisticated equipment never used before was employed, what appeared to be defects were found in the reactor vessel at Doel Unit 3.  This led to wide speculation about the vessels manufactured by Rotterdam Dockyard, and resulted in this extensive article I wrote for ANS in August 2012.

Eventually all US units were cleared of any suspicion, and so were all others elsewhere except for Tihange Unit 2, where similar defects seemed to exist.  These were later determined to be caused by hydrogen inclusion in the pressure vessels, and Electrabel (owner of the two nuclear units in question) decided that the units were safe to restart.  It submitted a restart plan to the Belgian nuclear regulator, FANC, in late 2012.

After much back-and-forth between FANC and Electrabel covering short and long term requirements, both plants were allowed to restart in May 2013.

What has happened now is that hydrogen flaked reactor pressure vessel test samples which were being irradiated and then tested to demonstrate strength have shown a marked change in material characteristics - for the worse.  The two plants were placed in their scheduled outages earlier than originally scheduled, but are now being held shut down by FANC until further notice.

What's required now is to repeat these material tests and determine if they're anomalous, or if the material properties of the reactor pressure vessels really are seriously affected by this phenomenon.. and if so, how?  In some old US pressure vessels, certain welding designs have caused operators to place highly restrictive operating limits on the plants -- limits which still can be met in plant operation, and the plants have operated safely.  Is this the sort of fate that faces Doel 3 and Tihange 2?  Or, is a permanent shutdown in the cards?  This is impossible to say at this point; Electrabel has stressed that early results of the tests underway don't point up any conclusion as of yet, and that results are due in the fall.

More troubling perhaps is the recent shutdown of Doel Unit 4 due to apparent sabotage, when person or persons unknown dumped lubricating oil from the turbine generator under full load.  The turbine tripped, which caused a reactor trip as well.  The HP or high pressure turbine has been reported to be seriously damaged; no results of inspection of the associated low pressure turbines have been released.

It's safe to say that Electrabel and FANC have their hands full at the moment, investigating one serious apparent sabotage event at a nuclear plant (even though that event was highly unlikely to have led to any reactor fuel damage) and two cases of possible, yet undetermined, degradation of reactor pressure vessels' integrity.  We await the outcomes of the two investigations and will report on those here when they're known.

TURBINE GENERATORS AT NUCLEAR PLANTS

Turbine generators have traditionally been the largest and most expensive single pieces of equipment installed at nuclear plants (WASH 1174-71, US AEC 1971.)  These are shipped to the site in large sections, and assembled on top of a large steel reinforced concrete turbine pedestal.  A typical turbine generator set for a US 1000 MWe nuclear plant has one high pressure turbine and three low pressure turbines (all mounted on a single, linear, sectional shaft) and runs at a constant 1800 RPM.  In years past, growth of nuclear plants' output was perceived to be limited by the growth in turbine generators, because the single piece forgings required for the low pressure turbine rotors were the largest single piece forgings being manufactured anywhere.  The AEC's 1968 report WASH 1082 stated that, at that time, the largest single forging available in the US for use as a turbine rotor was 175 tons but 190 ton forgings for large 1000 MWe turbine generators were going to be required - but also noted that these forgings were ONLY used for nuclear plant turbine generators, thus presenting an investment risk to companies choosing to develop and install such equipment as was required to make these parts.  The former Soviet Union avoided this problem (and others relating to turbine blade length) by installing two, half-capacity turbine generators at many of its earlier nuclear power plants; in later years, it developed single 1000 MWe-plus turbine generators.

Below, a typical General Electric 1000 MWe turbine generator with parts listed in key below illustration.  Westinghouse units, and in fact all other types (Siemens-Allis, Brown-Boveri, GEC) are broadly similar overall.


Key:  Steam from the nuclear power plant's NSSS (Nuclear Steam Supply System) which is not shown is first piped to the HP or High Pressure turbine, (1).  After expanding through and driving this turbine, the steam exhaust is routed out from under this turbine to four moisture separators (2).  After having any water removed (due to condensation) this steam is then routed down the sides of the turbine generator through pipes and six large stop valves (3) to the three identical LP or Low Pressure turbines (4).  The four turbines are driving the generator (5).  The entire assembly is supported by an enormously heavy and strong turbine generator support structure, (6).  Note the figure of a man standing next to the HP turbine for scale.

A turbine generator as shown here, not including the support structure or moisture separators, is roughly 220 feet long, 23 feet wide and weighs approximately 5100 tons (The Nuclear Industry 1969, US AEC.)  Newer turbine generators actually include moisture separator / reheaters between the HP and LP stages to reheat the steam before it enters the LP turbines.  This illustration is thus what we call a "straight" or "non-reheat" turbine generator.

The output of this turbine generator is roughly 1000 MWe, or about 1,341,000 horsepower.

Turbine generators at light-water-cooled reactor nuclear plants are much larger per MW of output than those at fossil fired plants; fossil plants produce steam at much higher temperatures (superheated) and thus can employ smaller and faster running turbine generators for a given output than nuclear plants.  Gas cooled, organic cooled and sodium cooled reactors can, however, produce this highly superheated steam and so would theoretically save size and cost on turbine generators.

Item:  In some areas of the world, such as parts of Japan (but not all of it) the electric distribution system uses 50 Hz and not 60 Hz frequency.  In those instances, the turbine generators at nuclear plants are a slightly different design and are built to run at 1500 RPM and not 1800 RPM.

BBC News on NS SAVANNAH


BBC News wished to do a piece that remarked upon the 50th anniversary of the visit of NS Savannah to Southampton, and other places in the UK during her big European tour, and to that end this last week contacted me (since I'm the Communications Director for the N.S. Savannah Association) to find out some facts and history.

I spoke to Justin Parkinson on the phone for something over a half hour, I think; he was well informed, and enthusiastic.  I put him in touch with another member of the NSSA, Stan Wheatley, who was Chief Engineer of the ship when it went to the UK, because it was desired to speak to someone actually on board during that historic visit.

Although BBC didn't use all the material we spoke or sent, their piece came off quite well, I believe, and is a good example of the level sort of reporting that nuclear in general is getting these days over there. 

•Click here to see the BBC article.

Oh - by the way.  The photos on this piece that are credited "American Nuclear Society" were taken by me for the two articles we did on the ship.  The illustration of the prospective UK nuclear powered ocean liner is mine, and will eventually be part of the NS Savannah Association collection.

What's rotten in the state of Denmark?  Electricity policy - and it's more rotten in Germany

Denmark, as its government proudly proclaims, is a nation of cyclists.  But Steve Aplin, an Ontarian and proud publisher of 'Canadian Energy Issues,' points out that Denmark is also a country of CO2 profligates where electric power generation is concerned.  The average Dane, riding around on his or her bicycle, scrupulously recycling his or her cans and bottles, and using much less electricity than the average Ontarian, had an electricity CO2 footprint nearly three times that of the average Ontarian. Aplin urges Danes, and Germans, to stop congratulating themselves and acknowledge they have been misled into supporting terrible energy policies.  Only then will they have any real hope of reducing CO2.

Andrew Cuomo has made no secret of his desire to close the Indian Point nuclear station as soon as possible.  Though he has no authority to order the plant to shut down, he is doing everything in his power to develop alternate sources of electricity, and interest groups that want to use those sources instead of continuing to use the electricity from Indian Point.

The topic of safely transporting and storing used nuclear fuel at U.S. nuclear energy facilities is causing a lot of discussion in communities around the country.  Questions about radiation shielding, safety and seismic capabilities are prompting the most responses, but there are also persistent misunderstandings about safely managing used nuclear fuel that muddy the conversation.  By Mike McMahon, Senior Vice President, AREVA TN Americas.

China's President says development of nuclear energy should be accelerated

At the end of 2013, China's 17 operational nuclear power plants were producing about 2 percent of the country's total energy, according to Xinhua news.  But Ye Qizhen, an expert in nuclear energy at the Chinese Academy of Engineering says that China should aim to get 10 percent of its energy from nuclear.  China's President has also called for accelerated research in nuclear power.

China looking seriously at supercritical water cooled reactors

China has completed the basic technology research and published a development roadmap for a Generation IV demonstration supercritical water cooled reactor that could be commissioned in 2022.

No new transmission lines for Vermont!  Vermont government reacts to Vermont Yankee closing

During the polar vortex in January, New England governors asked regulators to fast track the building of new gas pipelines and tranmission lines to serve the area.  Governor Shumlin of Vermont signed this petition, but later, he reversed himself.  In June, Shumlin said that we should go slow on transmission projects -- such projects become outdated as new energy technologies are developed.  Shumlin's words were almost certainly a bargaining ploy.  With Shumlin speaking against them, the project developers were warned that they would have to pay more (taxes, special funds) in order to do business in Vermont.

The Hiroshima Syndrome / Les Corrice

Nuclear obsession covers up impact of tsunami on refugees

The amount of property damage done by the earthquake / tsunami in Fukushima Prefecture is staggering, and is statistically much worse than in Iwate Prefecture.  However, the Japanese press and government never report on the obvious.  Tens of thousands of Fukushima "evacuees" would be homeless tsunami refugees if the nuclear accident had never happened, and the rate of "related" deaths in Fukushima Prefecture is almost exactly the same as in Iwate Prefecture.  But, the news reports on the matter make it seem as if all Fukushima related deaths are because of the nuclear accident.  This is a monumental coverup of the truth by the press and government.

----------

That's it for the entries this week.  THANK YOU to all of the contributors for great material. 

Now, what was that?  The illustration comes from the cover of a sales brochure covering ACF Nuclear Products - ERCO Division of ACF Incorporated's pool training reactor.  So, if you said "pool training reactor" or "pool type reactor" or "training reactor," you win. 

The reactor core is at the very lower right of the cutaway; the shielding blocks and tank have been cut away to reveal the large, non-pumped pool.  The fuel elements offered were 3" by 3" MTR type, either 20% or 90% enriched. (Such elements were available "off the shelf" from Sylvania-Corning Nuclear at the time, at either enrichment.)  Test locations included a through tube (4" diameter) and two beam tubes (also each 4" diameter.)  A 2.5 foot square thermal area or "column" was provided beside the core for experiments requiring thermal neutrons.




ACF Industries only had a nuclear power division for a short time in the mid-late 1950's.  The company sold a number of training and test reactors, and offered more designs than it sold.  A different sales brochure offers a standard ACF Heavy Water Tank Type (based on MIT and Italian reactors, see below), an ACF Light Water Tank Type, rated from 10 MWt to 30 MWt, and two power reactors - a boiling water reactor and a gas cooled reactor.

Here are the ACF reactors of which I'm aware.

ACF Research reactors

Italy - Italian Nat'l Committee on Nuclear Research - 5 MWt heavy water tank type.  Said by ACF to be "the first sale of an atomic reactor abroad by a U.S. firm," the contract was awarded to ACF in February 1956 with the actual signing occurring later that year.

USA - MIT Reactor (MITR) - designed by MIT staff, ACF principal contractor.  Heavy water tank type, 2 MWt.

Netherlands - Gov't Reactor Center, Petten - 20 MWt pool type.  ACF selected for this project May, 1956.

Sweden - Gov't Atomic Energy Commission, Studsvik - 30 MWt pool type.  ACF selected for this project October, 1956.

USA - US Air Force, Wright-Patterson Air Force Base, Dayton Ohio.  NETR - "Nuclear Engineering Test Reactor," 10 MWt pool type reactor.

ACF Power reactors

Elk River Reactor - ACF awarded this contract after the original reactor vendor, AMF, decided to shut down its nuclear business. 

Note on above reactors:  ACF Industries sold its nuclear power business to Allis-Chalmers Manufacturing Company in 1959, with the result that Allis-Chalmers completed most or all of the reactors above.  It's certain that Allis-Chalmers was in charge prior to the completion of the NETR, the Netherlands reactor, Elk River.

The illustration you saw at the top of this article is actually the 1 watt (thermal) pool type training reactor designed by ACF in 1958.  This model was "portable, prefabricated" and sold for less than $150,000.  ACF said that it was "the least expensive reactor of its kind being offered."  It required only standard laboratory utilities, could be installed in existing buildings without excavation, required only a 40 ft. by 40 ft. floor area.  ACF offered to supply the following services:  Supervision of installation, training of operators, a service guarantee, laboratory manual, and assistance in preparation of (AEC) hazards report. 




The back page of a different brochure entitled "ACF - Specialists in Reactor Diversification" says that "Only the ACF Pool Training Reactor offers all these features:

•Versatility of pool type reactor
•Safe, Simple operation
•Full scale instrumentation and control system
•Complete experimental facilities
•Flexible fuel arrangement
•No excavation ... can be housed in existing buildings
•Minimum maintenance and operation costs."

The brochure also says "ACF will prefabricate, deliver and install, at customers' site complete reactor including instrumentation and shielding.  ACF will also supply operator training."

Found in the original brochure whose cover was shown at top was a mailing card.




The ACF nuclear division had some famous names associated with it during its short span of life from 1954 to 1959.  For example, for a time its President was Dr. Marshall G. Holloway; Harold Etherington was for a time, its Vice President.  It had a good business on its hands when it was sold to Allis-Chalmers, who desperately wished to both expand its nuclear business generally and wished to get into power reactors specifically.  Buying ACF's Nuclear Products Division got it both the Elk River power reactor project which was already underway, and a joint project for the Air Force with Kaiser Engineers on a gas cooled power reactor for Oak Ridge National Laboratory -- which ultimately was built but never operated, putting it roughly in the same group as the NETR at Dayton, Ohio.

That's it for this week's Carnival.  I hope you enjoyed the entries and the walk down memory lane!

Fukushima Daiichi Accident Reports page updated

A reminder for APR readers; I have long maintained a stand-alone page on this blog which compiles links to comprehensive Fukushima Daiichi accident reports.  Some of these detail the accident, while other detail the recovery from it; still others detail the responses in other nations to the accident, whether from a design / operation standpoint or a regulatory standpoint.

I've added a couple of new links to that page today, and will note that a few others have gone in sporadically since the start of the year. 

Click here to see that page; it is always available by the link in the right sidebar.

EPA Announcement; Where To From Here?

DTE Fermi 2 (right) and planned Fermi 3 (lower); courtesy DTE

...and, just like that!  We have, in the last 24 hours, at least in the minds of some, seen a complete reversal of fortune for nuclear power -- the dying former "nuclear renaissance" having been replaced by what is being breathlessly debated far and wide as a GHG emergency, whose ill effects the EPA will now quash by projecting emissions limits out a couple decades in the future and which can only be met by either nuclear power or some combination of renewables.  Calls for nuclear power to make an exceedingly rapid return are all about us today. 

US Pledges Power Sector Carbon Cuts

EPA Carbon Rules will show Nuclear, Environmentalists not Strange Bedfellows

EPA Issues Expansive Rules - Nuclear Might Be One Winner

These go on and on.  So what do we do from here?  There are lots of ideas floating around, lots of camps claiming immediate victory, lots of camps claiming immediate economic collapse, and more.  Let's take a breath here and make just a few quick, but calm, assessments that can give us a base for thought and further consideration.


1.  Think about 1000 MWe-class (large) nuclear plants sooner rather than later.

States will have "interim" goals to be met in the 2020's, and final goals (in total GHG emissions) to be met by 2030.  If we think about it rationally, in order for new large commercial nuclear plants to help out in this time frame, they'll have to be ordered fairly soon. Not tomorrow, or next year, but soon.  During the major days of nuclear plant construction in this country, nuclear plants were being generally scheduled so that from the date of contract award (vendor, architect-engineer, constructor) to the date of commercial operation of the plant on the grid was six years.  Many were delayed far beyond this time frame.  In many cases, preparations were made long before the actual plant contracts were awarded - planning, site selection, interaction with the community, discovery of financing all have to be completed before the actual nuclear plant is ordered. 

It's already 2014.  Six years from now is 2020 - and I don't really believe we can count on much shorter than a five to six year time frame for nuclear plant construction.  For example, Westinghouse has stated in publicly available material that the goal for Nth of a kind construction on the AP1000 nuclear plant is five years from order placement to completion of startup testing (site prep 18 months, site construction 36 months, startup testing 6 months.)  Overruns are still more likely than not in time, even if not gigantically in construction cost (the cost of money due to the delay notwithstanding.) 

I'd expect that at least a few planned new nuclear generating stations that have been put off or had licensing work by NRC halted might get re-examined within the next six months to two years, after utilities figure out their options.  Utilities will need to figure out how they're going to meet the emission goals and their projected demands; nuclear may just get injected back into the mix, but ONLY if the projected power demand makes it profitable.  I do not expect a flood of new, yet unseen nuclear plant projects in the 1000 MWe+ class either; I do expect some reconsideration of shelved projects within a couple of years.


Perry Nuclear Plant.  Unit 1, nearer the lake, operates; Unit 2 incomplete.


2.  Quick - complete the unfinished nuclear plants we cancelled years back!

Nope.  Not even close to a reality. Even though historically over 100 nuclear reactors were ordered and then cancelled, and some remain partly finished as curious post-apocalyptic-looking landmarks, there is no "ghost fleet" here to call into action.  For starters, almost none of these sites has been extant in a vacuum, and population has likely changed around them - perhaps violating the original premises of plant siting near populated areas.  Environmental considerations (flora, fauna, water) may well be a "no go" at many sites too now.  This of course takes no consideration of the physical condition of unfinished (cancelled) nuclear plants .. some have been demolished in recent years (Marble Hill), some are left open to the elements and are essentially abandoned (every unfinished TVA plant except Bellefonte), and others were converted to something else (Midland, Zimmer.)  Some of the unfinished plant sites never even had the required high-tension transmission lines built to them - and there would be a whole other zoning and building mess.  If we look through the list of plants in any state of completion we rapidly find that precious few (such as Perry Unit 2, seen above) are completely contained or sealed, and maintained.  None of these may be in an area that would call for capacity that high -- unless of course new transmission could take the power where it's needed.  So although there might be a few specific plants this could work for, generally it's not a big resource.

All that said, some few utilities (such as FirstEnergy) could well find themselves with nuclear plants completed less expensively than new-built nuclear plants.  TVA certainly hopes so in the case of Bellefonte Units 1 and 2 .. and of course Watts Bar Unit 2 which it's now finishing.


3.  Let's get SMR's into action rapidly to replace fossil plants.

NOW you're talking. "Rapidly" is a relative term, though.  Two choices here - build new SMR driven power plants, or attempt "hook on" plants where an SMR provides steam to an existing facility.  The big stopper with that latter case is the fact that an SMR which is water cooled cannot produce superheated steam, which most fossil fired plants require.  A choice would be simply replacing the generating equipment with turbines suited for saturated steam, which would be expensive but perhaps not as expensive as a complete new plant because existing infrastructure such as service water, electric switchyard and so forth are retained and reused.  The other option is to retain the superheated steam turbine and interpose a fossil fired (perhaps natural gas) superheater between the nuclear steam supply system and the turbine.  This has been done before; while it complicates reactor control and load following, it has been proven as a concept at more than one nuclear plant - in one case, for example, the superheater was fired by oil (Indian Point Unit 1) while in another it was fired on pulverized coal (Elk River.) 

We might have to make a choice here, if we're to rush SMR's into the gap.  We can either directly fund the designs under consideration now for DOE assistance through construction (in the mPower case) or licensing (in the NuScale case) and hope one of them can get completed soon enough, OR we can choose to further the path already becoming apparent and drop one design from DOE funding and throw everything behind the other, in order to guarantee that one of them gets built sooner.  This is actually what happens when you "pick a winner," instead of what's happening now wherein we essentially temporarily designate two non-losers and hope their pockets are deep enough to skip along with DOE until a plant gets built somewhere, if someone wants one and will buy the power.


SMART SMR nuclear plant; concept art courtesy KAERI

Item: South Korea's SMART SMR is already licensed for construction in that country.  It is not inconceivable that a DCA could be fast-tracked by KAERI to get the design licensed here.  The question of who would build the plants remains, but in terms of completed designs this is the only complete and relatively powerful integral PWR SMR in the world.  It should be a consideration in any realistic plan to "get SMR's now," by virtue simply of having been the first design certified commercial iPWR SMR anywhere in the world.

4.  Now is the time to get moving on alternate technologies like high temperature gas cooled reactors, thorium fuel, and LFTR's!

No...  Not even close.  "Not even closer" than my thoughts on cancelled nuclear plants.  If we only have a short time to get moving on new non-GHG power generation, and if we surely have a limited supply of money, then now is precisely NOT the time to begin gambling on technologies that DIDN'T GET PICKED THE FIRST TIME AROUND for mass construction and deployment, and dilute funding going toward designs already underway.  Has everyone noticed that during the massive nuclear buildout in the U.S. in the 1960's - 1980's that only two commercial gas cooled plants were built, and NO LFTR or liquid fueled plants?  There are reasons for that, and they have nothing to do with weapons or politics.  They have to do with economics, with reliability, with proven records of PWR and BWR plants, and with the complete lack of desire on the part of anyone to spend all the money required to develop a completely separate and new fuel cycle (thorium.)  It would be a gigantic mistake ... if the peril really is serious ... to go off half-cocked in search of a unicorn when we have a perfectly good horse in the barn.  FINIS.

Well, ok, but does this move thorium up the ladder, you might say?  Yes, but only "yes" if we see a big surge in nuclear plant construction using uranium fuel that drives the price of uranium up far enough that investing in thorium becomes attractive - attractive because it would be profitable.  That would take a LOT of reactors, or a big surge in the number of announced reactors using U235.

Could this trend open the door to fuel reprocessing?  Maybe even a complete U fuel cycle with fast reactors?  No, probably not, and that might never happen here no matter how bad it gets because we seem to either decide that the "worst thing ever" is storage of spent LWR fuel, or else at some other times the proliferation concerns of fast reactors.  We really can't win on closing the fuel cycle if we can't even store spent LWR fuel without a daily fight.  So don't get your hopes up on massive extensions of the benefits (to nuclear) of this EPA plan beyond having SOME new nuclear generating capacity derived from conventional light water reactors mixed between some 1000 MWe class plants for sure, and perhaps some SMR plants later.  Not yet, anyway.

----------


That's it for now - I have many more observations about the EPA document, and concepts swirling around in its wake.  I leave you with just these observations in the hope that they spur discussion and rational thought as pro-nuclear advocates prepare for what is sure to be a welcoming crowd of new enthusiasts.  A LARGE crowd, I think.  They deserve the truth.  Give it to them, straight.

Could Korea, UAE partner in exporting nuclear plants?

Barakah Nuclear Plant, UAE


A very interesting development has taken place in the Republic of Korea's effort to export nuclear energy.  The ongoing project in the United Arab Emirates to build the Barakah NPP (four 1400 MWe units) has progressed conceptually to a consortium of Korea Electric Power Company (KEPCO) and Emirates Nuclear Energy Corporation (ENEC) working together to spread nuclear power through the Middle East and perhaps Africa.  This may indeed be that final kick needed to open the flood gate of Korean nuclear exports; we shall see.

Details at link below. 

KEPCO, ENEC could export more nuclear plants

Item:  KEPCO is already building a "build and operate" fossil fired plant in Saudi Arabia.  Could this be a predictor of perhaps a "build and operate" or "build - own - operate" scheme for nuclear plants in that country later on?  I say "maybe" to the first, and "unlikely since they're not Russian" to the second.  Link:  KEPCO breaks ground for power plant in Saudi Arabia

Another KEPCO plant in Saudi Arabia -- this article has more background on KEPCO's push into the Middle East.  KEPCO completes Saudi power plant

It's time for the 210th edition of the Carnival of Nuclear Bloggers and Authors.  Because this is a holiday (Memorial Day,) I'm going to skip the usual entertainment that goes along with the Carnival when it appears here and get straight to the entries.  And some very interesting and good entries they are, too!

Yes Vermont Yankee  - Meredith Angwin

Emergency Planning and Fuel Pools:  The Little Fire That Wasn't There

The Fukushima 4 Fuel Pool Fire (the one that didn't happen) is still the cause of political posturing and attacks on nuclear energy. In Vermont, opponents want Vermont Yankee to continue to fund the Emergency Planning Zone for as long as the fuel pool is in use. This would cost $20 million a year for seven years after plant shut-down. Meanwhile, in Congress, anti-nuclear senators have introduced several bills to force nuclear plants to continue that type of funding after the plant closes. (Post contains many useful links.)

Next Big Future - Brian Wang 

Russia could sign an agreement this year to build eight new reactors
for nuclear power plants in Iran, state-run Russian news agency RIA
reported on Thursday, citing a source it did not identify.

Russia built Iran's only operating nuclear power reactor, at the Bushehr plant.

http://nextbigfuture.com/2014/05/russia-could-build-eight-nuclear.html


Climate Change - Get beyond the controversial problem statement to the
shape of the proposed solutions after tens of trillions of dollars and
decades and see how much is or is not solved.

For Climate Change, the big UN IPCC proposed solution is to stabilize
[flatten at current levels of nearly 40 billion tons per year of CO2]
levels of greenhouse-gas emissions would require investments of about
$13 trillion through 2030.

It also noted that reducing emissions would reduce the rate of
economic growth (as a result of such factors as higher energy prices).
But it would do so by, on average, less than a tenth of a percentage
point per year between now and 2100. Switching from fossil fuels to
low-carbon sources of energy will cost $44 trillion between now and
2050.

* $13 trillion or nearly $1 trillion every year is the ante (poker
reference) to get started

Nuclear energy could be scaled up safely and more affordably. This has
been demonstrated on a national scale where France shifted to 80% of
electricity from nuclear power over the 1980s.

Conventional nuclear fission is a better plan than the IPCC proposal.
Future nuclear energy can be further improved with development of
molten salt reactors.Costs would be several times lower, reactors
would be even safer and waste would be reduced. Conventional nuclear
already compares very well to other energy sources based on actual
experience.

http://nextbigfuture.com/2014/05/why-do-so-many-proposed-solutions-to.html

Scientists at LPP Fusion, led by Chief Scientist Eric Lerner, are just
one step away from technically proving out dense plasma focus fusion
and you a few thousand other people can help for the final push. They
are already 37% of the way to the $200,000 they needed for a few key
experiments.

Success would be better than doubling NASA's budget and 100,000 times
cheaper than one year of double NASA budget

Success would have more impact than efforts to double NASA's space
budget to 1% of all US tax dollars [increase from $18 billion per year
to $36 billion].

http://nextbigfuture.com/2014/05/get-millions-of-times-more-bang-for.html

China continues to build a lot of coal plants and for the last 10-20
years China has built modern coal plants that have the latest
pollution mitigation technology. Why did they not turn on pollution
control until recent protests about air quality. It would have added
over 0.4 US cents per kwh to the costs for one of the technologies and
more for each of the other pollution control technologies. China is
making about 4000 billion kwh/year of electrical power from coal
power. So 0.4 cents per kwh is $16 billion/year.

http://nextbigfuture.com/2014/05/china-did-not-turn-on-pollution-control.html

The Manhattan Project employed more than 130,000 people and cost
nearly US$2 billion (about $26 billion in 2014 dollars). Over 90% of
the cost was for building factories and producing the fissile
materials, with less than 10% for development and production of the
weapons. Research and production took place at more than 30 sites
across the United States, the United Kingdom and Canada.

DARPA has around 240 (about 140 technical) directly managing a $3
billion budget. These figures are "on average" since DARPA focuses on
short-term (two to four year) projects run by small, purpose-built
teams.

DARPA biggest successes were being a major part of developing the
internet, Global positioning satellites, Speech translation, stealth
planes, and Gallium Arsenide.

>From 1989 to 2008 it is conservatively believed that $79 billion was
spent by the US government on climate change research, administration,
foreign aid, tax breaks and education (public relations).

Up to 2008, the EU Framework 7 programme includes €1.9 billion on
direct climate change research. Framework 6 ran to €769 million. If we
take all the Annex 1 countries, the sum expended must be well over
$100 billion.

The global carbon trading markets are at about $60 billion in 2014.

The Whitehouse report on climate change spending proposes a budget of
$21.4 billion.

The President’s 2014 Budget proposes over $21.4 billion for climate
change activities. This amount is $1.2 billion , or 5 percent, lower
than the 2013 enacted level for climate change programs, activities,
and related tax policies.

Nuclear Blogger and Author Carnival 205

It's time for the 205th Carnival of Nuclear Energy; a long-standing tradition among the top English language pro-nuclear bloggers and authors.

You'll get to see what it is they had to say last week about nuclear energy, nuclear policy and just about anything else related to nuclear matters after you try to guess what the following picture shows.  What is this?

 
"It's a diagram!" doesn't count, and none of that statement's relatives do either.  Here are your clues:
 
•This is a depiction of a boiling water power reactor that was actually built
•One of three forced recirculation pumps is at the right
•The control rod drives are above the reactor on this design
•This reactor was started up and shut down in the 1960's
 
That last clue should help nail it for some folks.  There are a number of peculiarities depicted here, which some might find quite helpful in identifying this reactor.  Your answer after the Carnival entries - and here they are!
 
----------
 

Forbes - Jim Conca
 
 
Russia's supply of half of Europe's fossil fuels has given Russia the upper hand in dealing with Europe, including its recent aggression towards Ukraine.  Replacement of coal with gas, and shutting of nuclear plants, in the EU has made Ukrainian natural gas pipelines even more critical to this conflict. 
 
 
Can we stop pretending biofuel corn is helping the planet and the environment?  The United Nations Intergovernmental Panel on Climate Change released a new report reversing its previous support of biofuels, stating "increasing bioenergy crop cultivation poses risks to ecosystems and biodiversity" and "[Use of biofuels]... can lead to greater total emissions than when using petroleum products."
 
----------
 
Canadian Energy Issues - Steve Aplin
 
 
On the occasion of the discovery of the planet Kepler 186f, Steve Aplin urges the Intergovernmental Panel on Climate Change to be more like the newly discovered planet's namesake, Johannes Kepler, in its assessment of nuclear energy as a way to reduce emissions of man-made carbon dioxide. The original Kepler laboured under illusions for years before accepting what his data and critical faculties told him: that planets travel about the sun in elliptical, not circular orbits. The IPCC labours under much worse illusions about the alleged risks of nuclear.
 
----------
 
Yes Vermont Yankee - Meredith Angwin
 
 
Recently, the Vermont Public Service Board wrote an order authorizing Vermont Yankee to continue to operate through the end of the year.  In that order, the Board rewrote history by accusing Entergy of not being a "fair partner" to the state.
 
----------
 
Atomic Insights - Rod Adams
 
 
Rod Adams took a field trip to Princeton, N.J. to attend a symposium titled "Speaking Knowledge to Power" that featured talks by four public policy scientists.  Three of the four headliners - John Holdren, Allison Macfarlane, and Frank von Hippel have reputations as skeptics about nuclear energy.  Rod asked a couple of challenging questions. 
 
----------
 
Nuke Power Talk - Gail Marcus
 
 
Gail Marcus comments at Nuke Power Talk on the continuing drumbeat of opposition to seemingly every energy installation, noting all the special interests that come into play whenever a siting decision needs to be made. Given that there are many legitimate interests that do need to be served, she finds the challenge a bit daunting. However, she notes that the proposed smaller reactors now being discussed would have a minimal footprint, and that could conceivably present an attractive solution to many of the legitimate interests.
 
----------
 
Next Big Future - Brian Wang
 
China stockpiled about 24000 tons of extra uranium purchased at the
price of about $35 per pound. This was above the 6300 tons that China
needed to run their current nuclear reactors. Total 2013 uranium
imports into China reached $2.39 billion

A new design for nuclear plants built on floating platforms, modeled
after those used for offshore oil drilling, could help avoid problems
from Tsunamis and earthquakes. Such floating plants would be designed
to be automatically cooled by the surrounding seawater in a worst-case
scenario, which would indefinitely prevent any melting of fuel rods,
or escape of radioactive material.

Plants could be built in a shipyard, then towed to their destinations
five to seven miles offshore, where they would be moored to the
seafloor and connected to land by an underwater electric transmission
line.

* Silex will cut the cost of nuclear fuel, a minor cost of nuclear
power. Terrestrial Energy will cut the capital cost of nuclear plants-
the major cost of nuclear power.

* Eighty percent of the cost of nuclear power is the capital cost of
the power plant. The fuel is less than ten percent.

* Integral Molten Salt Reactor powered electricity give promise of
being cheaper and safer cheaper than coal or conventional nuclear
powered electricity.

Will Davis takes a look at the final fate of the first floating, but non self-propelled nuclear power station ever built - the AEC / Army STURGIS.  Converted (if that's the proper sense) from a Liberty Ship in the 1960's, the plant operated unknown to most people for years in Central America.  Now, her final fate has been determined.  Photos, details and background links.

San Luis Obispo shows us how to expose antinuclear pseudo-science

Last week, the San Luis Obispo County Public Health Department posted a rejection of J. Mangano's claim of elevated health risks from the routine operation of the Diablo Canyon nuclear station. The SLO rebuttal concludes "There are substantial and obvious problems in methodology wherein basic statistical precepts were overlooked. In addition, the study shows selection bias in choosing case and control groups.” The SLO report should become a model for response to antinuclear pseudo-science.

That's it for this week's entries!  Now, what was that we saw earlier?
 

 
What you saw earlier is a view of the reactor vessel and one of the recirc loops from the Pathfinder Atomic Power Plant, which was (as you can tell by the post card view above) located in Sioux Falls, South Dakota.  This reactor's somewhat unusual external configuration was due to the fact that it employed internal nuclear superheating for its output steam.  Without getting too complex, the reactor was essentially two reactors in one - a central superheating section, with the boiler section wrapped around it.  The large diameter pipe you can see exiting the reactor vessel in the downward direction in the drawing is actually the steam outlet from the superheater, which then proceeds to the turbine building.  The reactor (designed and built by Allis-Chalmers) was ultimately unsuccessful.
 
The drawing is just part of one of many hundreds I've just acquired from an anonymous donor who shipped me over thirty pounds of original Pathfinder operating manuals.  This donor had acquired them secondhand from original operators of Pathfinder, and kept them all these years (the plant was shut down for good in 1967) until deciding to donate them to me.  Since all my historical material will go to the American Nuclear Society when I pass on anyway, these manuals are sure to be among those that remain for posterity.
 
And for those chomping at the bit -  YES, you'll see some more of these manuals on this site from time to time.
 
Thanks for reading this 205th Carnival!  And thanks to all of the contributors for their tireless work.
