Nuclear Expert: Fukushima spent fuel has 85 times more cesium than released at Chernobyl — “It would destroy the world environment and our civilization… an issue of human survival” -Former UN adviser

http://akiomatsumura.com/2012/04/682.html

[...] I asked top spent-fuel pools expert Mr. Robert Alvarez, former Senior Policy Adviser to the Secretary and Deputy Assistant Secretary for National Security and the Environment at the U.S. Department of Energy, for an explanation of the potential impact of the 11,421 rods.

I received an astounding response from Mr. Alvarez [updated 4/5/12]:

In recent times, more information about the spent fuel situation at the Fukushima-Dai-Ichi site has become known. It is my understanding that of the 1,532 spent fuel assemblies in reactor No. 304 assemblies are fresh and unirradiated. This then leaves 1,231 irradiated spent fuel rods in pool No. 4, which contain roughly 37 million curies (~1.4E+18 Becquerel) of long-lived radioactivity. The No. 4 pool is about 100 feet above ground, is structurally damaged and is exposed to the open elements. If an earthquake or other event were to cause this pool to drain this could result in a catastrophic radiological fire involving nearly 10 times the amount of Cs-137 released by the Chernobyl accident.

The infrastructure to safely remove this material was destroyed as it was at the other three reactors. Spent reactor fuel cannot be simply lifted into the air by a crane as if it were routine cargo. In order to prevent severe radiation exposures, fires and possible explosions, it must be transferred at all times in water and heavily shielded structures into dry casks.. As this has never been done before, the removal of the spent fuel from the pools at the damaged Fukushima-Dai-Ichi reactors will require a major and time-consuming re-construction effort and will be charting in unknown waters. Despite the enormous destruction cased at the Da–Ichi site, dry casks holding a smaller amount of spent fuel appear to be unscathed.

Based on U.S. Energy Department data, assuming a total of 11,138 spent fuel assemblies are being stored at the Dai-Ichi site, nearly all, which is in pools. They contain roughly 336 million curies (~1.2 E+19 Bq) of long-lived radioactivity. About 134 million curies is Cesium-137 — roughly 85 times the amount of Cs-137 released at the Chernobyl accident as estimated by the U.S. National Council on Radiation Protection (NCRP). The total spent reactor fuel inventory at the Fukushima-Daichi site contains nearly half of the total amount of Cs-137 estimated by the NCRP to have been released by all atmospheric nuclear weapons testing, Chernobyl, and world-wide reprocessing plants (~270 million curies or ~9.9 E+18 Becquerel).

It is important for the public to understand that reactors that have been operating for decades, such as those at the Fukushima-Dai-Ichi site have generated some of the largest concentrations of radioactivity on the planet.

Many of our readers might find it difficult to appreciate the actual meaning of the figure, yet we can grasp what 85 times more Cesium-137 than the Chernobyl would mean. It would destroy the world environment and our civilization. This is not rocket science, nor does it connect to the pugilistic debate over nuclear power plants. This is an issue of human survival. [...]

Actual Science

Actual Science and engineering would be a plus!

Suppose we deal with SCIENCE and ENGINEERING as opposed to propaganda, lies, advertisements, promotional material, unjustified-safety-assurances, as well as superstition and unreasoning fear. Cool, INTACT spent fuel bundles, in a radiation shielding pool are not ACTUALLY dangerous. For brief periods of time, highly trained scuba divers swim in the spent fuel pools. Some expert divers receive big radiation doses, when things go wrong, even under tightly controlled circumstances. There are thus, a number of SERIOUS POTENTIAL DANGERS, associated with Spent Fuel.

Some of the ACTUAL PROBLEMS observed, at the Fukushima Spent Fuel Pools presumably include: damaged (burned) fuel bundles, corium slugs, contamination, unreliable cooling, high measured radiation, contamination, non-redundant filtering capability, unstable non-redundant electrical power supplies, and seismic degradation of the pool(s) structural integrity. Some very bad things have happened at Fukushima, since Mid-March 2011, due to PISSPORE TEPCO operations. The potential exists for a substantially more serious nuclear accident at Fukushima than occurred during the week of 311. The odds don’t look good, given the operational complexity and the OBVIOUSLY limited capabilities of the ‘On-Site-Team’.

Oh and the local population is already biologically compromised by their previous and ongoing exposures.

SAFETY AND SECURITY OF COMMERCIAL SPENT NUCLEAR FUEL STORAGE

Public Report

The committee could probably design configurations in which fuel might be deformed or relocated to enable its re-criticality, but the committee judges such an event to be unlikely. Also, the committee notes that while re-criticality would certainly be an undesirable outcome, criticality accidents have happened several times at locations around the world and have not been catastrophic offsite. An accompanying breach of the fuel cladding would still be the chief concern.

That is, the reaction heat will increase temperatures in adjacent areas of the fuel rod, which in turn will accelerate oxidation and release even more heat. Autocatalytic oxidation leading to a “runaway” reaction requires a complex balance of heat and mass transfer, so assigning a specific ignition temperature is not possible. Empirical equations have been developed to predict the reaction rate as a function of temperature when steam and oxygen supply are not limited (see, e.g., Tong and Weisman, 1996, p. 223). Numerous scaled experiments have found that the oxidation reaction proceeds very slowly below approximately 900°C (1700°F).

I have written a series of articles on Fukushima on my blog http://www.puremalarkey.com I think the problems remain so severe that Japan needs to cooperate globally.

Watch the Japanese propaganda video that promises radiation won't harm you if you just "laugh". It is a video of Dr. Shunichi Yamashita -- now known as "Dr. Brainwasher" -- giving a propaganda lecture on March 21, 2011 in Fukushima City.

Natural News exclusive: Fukushima victim exposes Japanese government's attempted bizarre brainwashing of radiation victims

This blogspot website has located and translated several key brainwashing phrases uttered by Dr. Yamashita as part of the Japanese government's propaganda campaign. The following statements span several online videos featuring "Dr. Brainwasher." Each of these statements is a total propaganda fabrication. The comments in ALL CAPS are my own:

• "To tell you the truth, radiation doesn't affect people who are smiling. Only those who are worried. This has clearly been demonstrated by animal studies." (HUH? WHAH?)

• "Laughter will remove your radiation phobia." (COOL, 'CUZ I'M LAUGHING ALREADY!)

• "If you laugh, radiation won't get you." (NOW I CAN SAFELY WORK AT A MAMMOGRAPHY CLINIC!)

• "Internal exposure has 10 times less health risk than external exposure." (SO IF I EAT URANIUM, IT'S SAFER THAN USING IT AS A SKIN WHITENING CREAM?)

• "Children can play outdoors." (AS LONG AS YOU DON'T MIND THEM DYING)

PSYCHO Propaganda II

More total BS from Dr. Brainwash … I wuz wunderin where dat lyin, scrawny, blonde – Ann Coulter ‘is getting it’, and where John Boice learned to shovel this horse-dung. It appears that Dr. Brainwash is the ‘muther-load’. And what a stinking-butt-load it is. Follows, more translations and commentary from Mike Adams, the Health Ranger, Editor of NaturalNews.com.

• "I can tell you this, the health effects [of Fukushima radiation exposure] are minimal." (TO COCKROACHES)

• "We don't have to worry about the health effects of ordinary people." (BECAUSE WE DON'T REALLY CARE IF ORDINARY PEOPLE DIE ANYWAY)

"The total spent reactor fuel

"The total spent reactor fuel inventory at the Fukushima-Daichi site contains nearly half of the total amount of Cs-137 estimated by the NCRP to have been released by all atmospheric nuclear weapons testing, Chernobyl, and world-wide reprocessing plants (~270 million curies or ~9.9 E+18 Becquerel)."

So according to this article the total world wide contamination of CS-137 would go up by 50% compared to the near undetectable levels that are already there from previous events.

But somehow that's going to extinguish all life on earth?

Diemos

ELE Risk

The 'Village Idiot' V. I. Diemos confuses: past, present, future as well as reality, risk and probability.

The RISK of a DEVASTATING LOCALIZED Extinction EVENT and/or a general ELE, relates to potential FUTURE screw-ups at the FDNPP Spent Fuel Pools; or for that matter a similar screw-up at virtually ANY brimming-full Spent Fuel Pool on earth.

Possibly the 'Worst Case Scenario', is a WIDENING Evacuation region, due to a meltdown AND fission event at a Spent Fuel Pool. In the instant case, a collapse of the Unit 4 Spent Fuel Pool causes a forced evacuation of the entire FDNPP facility, due to EXTREME radiation and ongoing fissioning. Thus ALL the reactors and Spent Fuel Pools are abandoned and uncooled. They all then melt down.

This radiation could theoretically cause the FORCED evacuation of the TEPCO Daini NPP which is about 8 miles away. And sequentially, all ~ 60 Spent Fuel Pools in Japan could (theoretically) suffer the same fate.

This is neither a prediction nor are probabilities assigned herein to such events. It is merely a discussion of one possible, worst case scenario. There are others.

Background radiation numbers

Courtesy of the Health Physics Society chapter at the University of Michigan:

http://www.umich.edu/~radinfo/introduction/radrus.htm

The average person's radiation exposure due to all atmospheric nuclear weapons testing is given in the above table under "Fallout" as being <0.03 % of the average person's background dose.

That is; Mother Nature continues to be the largest source of the average person's radiation exposure by a factor greater than 3000!

So by increasing the Cs-137 exposure by 50%; one is making a 50% increase in a very small percentage of our radiation exposure.

It's only the unthinking, unprincipled, lying, anti-nuclear progandists that say that this is going to extinguish all life on Earth. What do the scientists say? Here's the testimony to Congress by the past President of the Health Physics Society; a Professor of Medicine at Vanderbilt University Medical School and a cancer epidimeologist with the Vanderbilt-Ingram Cancer Center:

Old Study , Cherry Picked Data

Your Uof M link uses data from the 1980's and is outdated. It is based on the National Council on Radiation Protection and Measurement (NCRP 93) that has been has been replaced by NCRP 160
http://www.ncrponline.org/Publications/Press_Releases/160press.htmly

Dr Boise's statements to Congress on May 13, 2011 have been rejected by the scientific community. At the time of Boice's testimony not all the data had been collected and studied, in essence Dr. Boice cherry picked data. Since that time, Fukushima has continued to leak radioactive water into the Pacific. To this day the data is still coming in. Dr. Boice's comments sound like the words of George W. Bush "mission accomplished".

THINK about it!!!

The U of M link and the NCRP 93 study are NOT OUTDATED when it comes to NATURAL radiation.

The rate at which we receive radiation exposure due to natural sources such as cosmic rays, Carbon-14, Tritium...and other natural radiation sources is the same because those sources are in equilibrium. Radon is produced as a byproduct of Uranium decay, and the half-lives of Uranium isotopes are in the MILLIONS of years.

The radiation exposure due to fallout from nuclear tests is decaying with the 29 year / 30 year half-lives of Strontium-90 / Cesium-137 which are the longest lived components of nuclear test fallout.

Why don't you look at the NCRP 160 study; which shows the SAME radiation exposure rates for natural radiation and fallout as the NCRP '93 study. The main difference between NCRP 160 and the NCRP '93 study is an increase in the radiation exposure due to medical sources, which wasn't part of the argument.

Please THINK before posting and ask yourself if any new data conflicts with the old data cited.

That's correct. Just because

That's correct. Just because we have a new report which contains the values of physical constants; doesn't mean that the old reports which also contain those values are outdated or in error. The new radiation study focused on the increased radiation dose due to diagnostic and theraputic medical uses of radiation. It's only these man-made uses that have changed in the last 20 years.

Candor

Candor is desirable, in life-threatening circumstances.

IMHO, John D. Boice is less than candid. Ann Coulter is a less than candid. Shunichi Yamashita is less than candid. Barack Obama is less than candid. The USA Congress is comprised of about 535 members who are less than candid. When they chat, candor is unlikely. In My Personal Opinion.

Cooled enough?

Its true #4 pool remains intact for two years, allowing cooling of the rods. Does this mean that exposing or dropping one would not cause it to ignite? Also any info on the other pools and rods seem rare. Does anyone have more data? Thanks

cooling is required

It is REPORTED, (by TEPCO), that the #4 Fuel Pool is intact. However, TEPCO lies continuously. The word 'intact' is not defined by TEPCO. The phrase "its true" probably does not belong in the same sentence as the acronym TEPCO.

There is no independent 3rd party confirmation.

The possibility that the #4 Fuel Pool, and the fuel therein, would satisfy my PERSONAL parameters, for 'INTACT', are probably kinda remote. There may be 30 melted bundles at the bottom of the pool, and another 30 mangled and holding by a thread. It is likely that the #3 Pool and fuel are 'hammered', due to the FDU-3 reactor detonation and the fuel pool heating..

IF an assembly is dropped, proximal to a 'near-critical-mass', given the unknown and unverified condition of the fuel and the pool, may God save us all. For statistically, ANYTHING COULD HAPPEN, including one or more criticalities at the Fukushima Daiichi site.

I suppose the worst case would be a widening evacuation area, leaving the ~ 60 spent fuel pools of Japan unattended, and uncooled. Thus, I would prefer steady hands, competence, integrity AND honor. I have no clue where to find such characteristics in the Nuclear Power industry. We can probably rule out Japan, USA, Germany, France and England. Perhaps the Russians ...

It also outlines the INITIAL, PLANNED response of the USA government, to the Fukushima nuclear disaster. It further documents several ARS deaths at the Fukushima Daiichi Power Station.

Due to relevant experience, I was invited to comment upon the BP 'live-feed', for the Macondo well blowout early underwater photography.

There was a wide angle feed and a closeup. The wide angle feed was murky and the closeup was clear water. So I commented that the two feeds were inconsistent. In a jiff, the closeup became murky with 'oil'. I then commented that the feeds were consistent.

“the nuclear disaster is

“the nuclear disaster is still going on”

http://ajw.asahi.com/article/views/editorial/AJ201308170027 August 17, 2013

EDITORIAL: Clearer government role needed for Fukushima cleanup

The crisis at Tokyo Electric Power Co.'s Fukushima No. 1 nuclear power plant is far from over. The government has yet to call off the state of nuclear emergency it declared on March 11, 2011, when the catastrophic earthquake and tsunami set off the nuclear accident.

Water contaminated with radioactive materials keeps leaking from the crippled plant, polluting underground soil and the sea in the area. This fact clearly shows that the nuclear disaster is still going on.

The government has made a big mistake by leaving it entirely to TEPCO. As a result, measures to stop leaks of radioactive water have been ineffective, allowing environmental pollution to escalate. The government's move to step in and get involved in the efforts to sort out the problem came far too late.

No release of the Cs

The fuel in the unit 4 spent fuel pool has been cooled for 2 years now. Due to the cooling this fuel can not cause a fire at this point. There is ongoing work on fires and spent fuel and it is not clear if a fire is ever credible but clearly not after two years of cooling. Dry storage casks often require only 5 years cooling. The cooling time limits are set from long term creep constraints certainly not fire and melting constraints.

If there were loss of water at the unit 4 pool now it would be a serious dose concern for the plant workers but not an event involving off-site populations. The radioactive material would be still contained in the fuel rod. It is very inappropriate to compare with the Chernobyl accident or nuclear weapons where the radioactive material was not contained.

Butt Load

What a butt load of crapola

If ANY spent fuel pool, for ANY nuclear reactor on earth, LOST COOLING, the results would be a GLOBAL catastrophe.

Let us be candid with respect to these matters. Let us strongly censure the idiots, liars and nuclear stakeholders attempting to divert our attention, from this reality.

This is NOT a drill

WRONG!

The above is certainly WRONG!

The radioactivity in the spent fuel elements decays exponentially; the greatest decay is in the earliest days. At some point, the rate at which heating takes place is low enough that passive, natural cooling can be effective.

For example, the electric incandescent lights in your home don't need active cooling. You don't need to supply either chilled water or forced air flow to keep an ordinary electric incandescent bulb cooled.

When the spent fuel has cooled to the point that the heat generation is comparable to electric incandescent lights - a few hundred watts - then passive cooling will also be effective; so you can't "lose" cooling.

So the quote above that "ANY" spent fuel pool is certainly INACCURATE and was stated only for the effect of needlessly scaring people with baseless PROPAGANDA by some anti-nuke.

Decay

At some point!

That 'some point' is WAY out there in time.

The Spent Fuel Pools in the USA are on average, on the order of 35 years old. The Cs-137 in the oldest bundle, will have half-lifed only once. The newest, spent fuel bundle, is 'hot as a firecracker', in every sense of that phrase, as the Cs-134 and Cs-137 are virtually at full strength.

So for example, if the newest bundle were exposed to air, and you walked up and touched it ... you would contract Acute Radiation Syndrome and die. That is hot in the sense of radioactive. The bundle would, in air, subsequently overheat and melt. It would, in the presence of water spray, burn even if subsequently submerged. That is HOT in the thermal sense. But you would likely be dead, by that point. So it would become the concern of someone else.

http://en.wikipedia.org/wiki/Decay_heat

"After one year, typical spent nuclear fuel generates about 10 kW of decay heat per tonne, decreasing to about 1 kW/t after ten years.[13] Hence effective active or passive cooling for spent nuclear fuel is required for a number of years."

Dry cask storage systems using convective air cooling are designed to dissipate 24kW of decay heat.

Nobody said that all sources are equal; which is what I think you are implying. ( I'm not quite sure what you are implying, since it is so poorly expressed. )

That wasn't the point. The point is that you complained about the accuracy of a source that turned out to be giving an accurate answer. Why not check out the answer to see if it is right or wrong before you call it "wrong" just because it doesn't say what you want it to say.

Qualify the Source

Low Source quality does not command ANY attention to the math and arguments which may follow. Of course, the heat-sink and Fuel Pool points were dangerously uniformed/disingenuous. So the primary source as well as the examples, math and applications are misleading at best, and more particularly, deliberate logical flaw --- LIES.

Why would anyone consider wikipedia, when VALID sources are easily available?

Light bulbs vs. spent fuel

The average weight of a light bulb is about 37 grams:

http://wiki.answers.com/Q/What_is_the_weight_of_a_light_bulb

So a metric tonne ( 1000 kilograms ) of light bulbs is:

1000 kilograms * 1000 grams / kilogram / ( 37 grams/light bulb ) = 27,000 bulbs

Assume each bulb is 100 watts = 0.1 kilowatts

A metric tonne of plugged in 100 watt bulbs generates 2,700 kilowatts of heat = 2.7 megawatts of heat.

So a metric tonne of plugged in 100 watt bulbs generates 270 times as much heat as would a metric tonne of nuclear waste after 1 year.

Natural convection has no problem cooling 27,000 light bulbs.

Electrical Load Banks

Rude Dog ignorance and plagiarism,

An interesting, (and no-doubt unattributed 'cut & paste) theoretical math exercise, however in the REAL physical world ...

I have had YEARS of experience with 'load banks' for electrical power sources. Small electrical 'load banks' consist of heat-sinked resistors, incandescent light bulbs and FANS. Else, the evolved heat would QUICKLY destroy the 'load bank' and wiring harnesses, indoors, in 25C air.

One heat-sinked thermal source can easily be designed as convective. As per usual, Rude Dog is an ignorant, uneducated, witless, amoral, idiotic LIAR. Rude Dog possesses exactly ZERO theoretical, educational, professional or practical understanding of ANY physical system. Any 'point-made' (attempted) by Rude Dog is ALWAYS USELESS, dangerous and brain-dead.

Fukushima and Chernobyl

There is all kinds of credible information from a number of different sources including UNSCEAR,
http://www.unscear.org/unscear/en/chernobyl.html, posted on the web that shows the damaging effects of radioactivity released into the atmosphere and the oceans. UNSCEAR report clearly states that many of the effects are ongoing and will manifest over a long period of time. There is also the problem of the accumulation of increasingly greater amounts in the food chain. Most reasonable people would question why we have to be exposed to any incidental radiation at all, if its so safe then why are such costly procedures necessary to clean it up and handle it safely. There is an infinite source of energy in the sun which can be tapped by the appropriate technology and that is where we should applying our efforts, utility companies aren't interested because they can't monoplolize the source and governments want to develop nuclear energy so they can make bombs. Solar energy is the cleanest safest bet, there is always the possibility the human race will be wiped out by accident so we don't have to make it any more likely by developing nuclear energy, except maybe on a very small basis, till the technology is fully perfected and 100% safe. Its far too dangerous to develop on a large scale. Corporations have yet to show that they have the will or the finances to dispose of the huge sums of nuclear waste that have already been created and are leaking out into the environment. By the way there is also plenty of info available on the web about how American soldiers were used as test guinea pigs for the US atomic testing program so people should look it up and don't believe comments you read on this board about how safe nuclear power is.

Allright! Thanks!

To who ever posted the below information. Thank you and right on! You really summarized why we need to wipe the guy from this site. See my post for this request.

The reason that the rude forum bully we all know as Mr. 'Demented Reality', 'Anti-Nuke', (who misrepresents himself as a Univ. Professor) so disgustingly engages in name calling and insults is because he is employed by the industry as a sock puppet in order to drive away any useful discussion regarding the ongoing disaster.
He is, unfortunately, very successful at driving away many people, who like myself tire of having to scan beyond his ugly comments in order to move to the other more useful comments posted by respected posters. I suppose he will continue to be with us much as the stink of an open outhouse is apparent to all those who find themselves downwind. Would it be that he was at least as useful as an open outhouse.
I'd like to thank those who are forced to slog around in the vomit of his diarrhea ridden mouth for continuing to supply useful information for the rest of us even under the harsh conditions he creates.
Thank you

Rude Dog

Rude Dog is the name bestowed on the TROLL. Sometimes the Rude Dog answers to the name and uses it himself. Mostly though, his 'writing style', vocabulary, pseudo-academic pretenses and attack-dog, lying approach give him away.

The Rude Dog betrays his lack of education, breeding, class, ability, experience, judgement, style, context, depth, character and professional standing in virtually every (unsigned) lying, post.

TTFN

Frustrated when Rude Dog shows you to be wrong?

I can see how frustrated you get when Rude Dog proves you to be wrong.

Instead of attacking the messenger; why don't you attempt infuse some ACCURACY in your posts; instead of posting what you WANT to be true for your own parochial purposes and political agenda?

More anti-nuke STUPIDITY and PROPAGANDA above.

Again we have some manifestly stupid anti-nuke spreading a bunch of propaganda.

The above poster states that the Government is interested in nuclear energy so it can make nuclear bombs. HOGWASH NONE of the material in the US nuclear weapons came from commercial reactors. ALL the nuclear material in US nuclear weapons came from the USA's special production reactors located at Hanford, Washington and Savannah River, South Carolina. The reactors at both these sites have been shutdown since the late '80s because the USA has all the weapons material it needs. Another grossly stupid anti-nuke didn't do his homework to see where weapons material came from, and is just posting propaganda.

The above poster thinks that solar power is the total solution. Solar power doesn't give you power at night. In fact the bulk of solar power comes in a 6 hour window from 9 am to 3 pm. When I tell this to solar proponents, they tell me we don't need power at night. Sure we do. The number one user of electricity in the average home is the refrigerator and it needs power at night or what's the use; your food is spoiled. In fact, the National Academy of Sciences states in their report on energy that only 20% of our electrical energy can come from renewables. That's because renewables are intermittent. We don't have a throttle on Mother Nature. We can only take what she gives. It's not sufficient to have the amount of energy from renewables equal the demand in an "average" over the day. It has to meet the demand second to second, or the grid falls.

Our idiot anti-nuke also didn't do his homework checking on how the disposal of nuclear waste is financed. The Government collects a special tax on nuclear generated electricity from the nuclear utilities as a condition of their license, and it is that money that is used to finance nuclear waste disposal. Google "Nuclear Waste Fund" or read the following:

http://www.huffingtonpost.com/2011/03/30/nuclear-waste-fund-us-24-billio...

We have above more proof that the anti-nukes are self-righteous, stupid, ignorant idiots that have no interest in providing the public and the readers of this forum with accurate information. They only want to spew their propaganda.

The anti-nukes get so angry when their propaganda is exposed!!!

The anti-nukes get so angry when their propaganda is exposed.

Anyone interested in good information isn't driven away by good information.

Only closed-minded anti-nukes that don't want to hear the truth are driven away; and that's no big loss. Their minds are made up regardless of the facts.

boil water

look at us, we are humans. we boil water with nuclear fuel. look at us we add nuclear material in the world that was not here before us. LOOK, we do it to boil water. To make steam. LOOK AT US.

you can't use solar panels at night? lulz well actually you can since you hook them to battery array. unless you stupid nuke person thinks its the actual solar panels running equipment?

Go boil some more water.

Now do the math!!

Now do the math as to the scale of energy storage you need.

Do you think you have batteries that can store many, many megawatt-days or gigawatt-days of energy? That is what you need!!

It always amuses me when I see anti-nukes attempting to disparage nuclear power by saying "it's just boiling water"; as if that is something foolish.

When it comes to turning heat into work, one of the best ways of doing that is via a thermodynamic cycle with a working fluid that undergoes a phase change. Of the many materials available, good old water is nearly an ideal working fluid.

Rankine steam cycles have efficiencies of about 40%; as compared to the 20% of solar cells that the scientifically ignorant anti-nukes find so sexy.

BWR

What's the percentage of produced energy lost as waste heat in a typical GE Boiling Water Reactor?

Seems silly to superheat water(?°F) in order to simply boil it 212°F

Aren't there significant inefficiencies involved there?
