254th Carnival of Nuclear Energy Bloggers

The Hiroshima Syndrome’s Fukushima Commentary is proudly hosting the 254th edition of the Carnival of Nuclear Bloggers. This week we have postings by Dan Yurman, Dr. Jim Conca, Meredith Angwin, Dr. Gail Marcus, Rod Adams, Rick Maltese, and Leslie Corrice.

Here’s the Fact or Fiction (?) quiz for this week… Albert Einstein’s book “Relativity” went through fifteen editions.

Now…for this week’s Blogs. To read the full articles, please click on the individual links. Blog topics for this edition include… French nuclear giant Areva addresses their debt, The NRC wants the USA to be similar to Europe, the latest on the political impact of closing Vermont Yankee, students visiting university reactors Washington State University, a rumor straight from Japan, the funding for SMRs by the DOE, and radiation experts telling Tokyo they should send Fukushima evacuees home now.

Areva Struggles to Dig Out of Debt

French nuclear company Areva says it will concentrate on the supply chain business in major components for reactors. Areva’s change in strategy comes as it struggles to overcome losses this year of 4.8 billion euros. Two projects in Finland and France represent the bulk of the current debt, but less than 10% of the firm’s revenue. Future core businesses will be uranium mining, nuclear fuel fabrication, recycling spent nuclear fuel, MOX and decommissioning.


Mideast nuclear projects report a mix of progress and perils

Recently, there has been considerable Mideast nuclear activity, including UAE applying for operating licenses for first two of four units, Turkey’s first of three major nuclear projects being delayed, Turkey’s second major nuclear project facing a political hurdle, and Jordan signing an agreement with Rosatom for two VVERs.

From Dr. Jim Conca of Forbes magazine (2) -  

The Nuclear Regulatory Commission Thinks America Should Be More Like Europe

The United States Nuclear Regulatory Commission thinks America should spend a lot of money and effort to change the safest radiological program in the world just so we can be the same as Europe. As if conformity in this area is important or that their safety record is better than ours. But, it isn’t. The price tag and unintended consequences will cost us many billions of dollars.


We Need To Get This Iranian Nuclear Deal Done

The nuclear deal being worked out with Iran is just what we all hoped for in the nuclear community. It’s a “don’t trust, just verify” approach, and is the first step to bringing Iran into the world’s nuclear community as a partner instead of an adversary, making Iran a compliant signatory of the Non-Proliferation Treaty. It would also diffuse a nuclear weapons race in the Middle East at a time when the region seems to be disintegrating into sectarian chaos.

Distributed Generation for Vermont: Making a Virtue of Necessity

Vermont Yankee used to generate 70% of the electricity which was made in the state.  Now, Vermont imports almost all its electricity from out of state, while officials boast about Vermont's future plans for small-scale electricity generation. The New England grid operator (ISO-NE) has a Consumer Liaison Group to advise the operator and protect the interests of consumers.  In mid-March, Meredith Angwin moderated the panel discussion for that group's Vermont meeting.  Vermont and Green Mountain Power officials spoke of their plans for "distributed generation."


Support for Ginna: Write a Comment to New York State 

Ginna Station is currently involved in a negotiation about a "reliability support services agreement" which would pay a slightly increased price for plant power, in return for the reliability and support that Ginna gives to the grid. To write a short note to New York regulators in support of this agreement, you can follow the links in this post.  (Over a thousand nuclear opponents have already sent in a form letter against the agreement.)  Meredith Angwin notes that nobody asked her if she wanted to support oil-burning plants when her local grid started a $80 million dollar Winter Reliability Program.  Support for Ginna must be put in context with many other actions that the grid operator takes to ensure reliability.

The next generation…and nuclear energy 

John Dobken of Energy Northwest reports about visiting students at Washington State University and Oregon State University, both home to TRIGA reactors.  The students who operate these reactors are bright, articulate and pro-nuclear. Dobken describes some of the students (not all are majoring in nuclear engineering). He also links to three short videos in which the students speak directly.


New poll reveals Washington state opinions on nuclear energy

(post by John Dobken) 

A new poll of Washington state residents show that 63% support the use of nuclear energy. Also, 53% feel we should definitely build more nuclear plants in the future. When poll participants were asked to list attributes of nuclear energy, they most often listed: advanced technology, reliable electricity, efficiency, and clean air.

California’s Water Emergency – A Solution Worth Considering

(Guest post by the Thorium Energy Silicon Valley group)

California has had problems made worse by shutting down their San Onofre Nuclear Generating Station. Here is a solution to a big problem that demonstrates what a nuclear plant can do, and will do if it's not too late.


Perception versus Reality

We live in a time when misinformation is increasingly shared. How can we persuade people about the role of nuclear energy to those that value human rights as a bigger issue than the environment?

Radiation experts advise Japan’s government to repopulate Fukushima

On March 24, 2015, five of the world’s most esteemed experts on the biological effects of radiation spoke in Tokyo. Scientific evidence was presented to show that the widespread belief of there being no safe level of radiation exposure is incorrect. Low-dose radiation levels of exposure in Fukushima pose no health risks to the public, thus full repopulation should be allowed as soon as possible.

Fact or Fiction (?) quiz answer – Fact.

Einstein seemed to have a strong desire to be understood by a wide audience, both scientific and lay. Albert began his quest to bring his ideas to the non-scientific, college-educated demographic, beginning with the first edition of his book “Relativity: The Special and General Theory” in 1916. He kept revising it until he died in order to make it easier to understand and “bring someone a few happy hours of suggestive thought”. The final edition, number 15, was published posthumously in 1961 by his estate. Please note, the book has a secondary subtitling, “A clear explanation that anyone can understand”. I highly recommend this little book to everyone.

Japan’s latest source of radiophobia – Rainwater!

And, we close with a thought-provoking poem by English poet Wendy Cope, submitted by Dr. Jim Conca…

He tells her that the Earth is flat -

He knows the facts, and that is that.

In altercations fierce and long

She tries her best to prove him wrong.

But he has learned to argue well.

He calls her arguments unsound

And often asks her not to yell.

She cannot win. He stands his ground. 

The planet goes on being round

Fact or Fiction (?) quiz answer – Fiction.

They eventually found that it was Barium, not Radium. They published their results in Naturwissenschaften (January 6, 1939). The process producing the Barium was called “nuclear fission”, using Bohr's model of the nucleus. The esearch paper appeared in Nature (February 11, 1939). Unfortunately, in a sign of the times, Lise’s contribution to the discovery was excluded by her peers. Hahn was given the Nobel Prize for discovering fission in 1944. Eventually, Meitner’s contribution was understood by the scientific community. The Nobel Prize omission was partly rectified in 1966, when Hahn and Meitner were co-awarded the U.S. Fermi Prize. Lise was also honored when element number 109 was named “Meitnerium” after it was created in 1982.

Japan’s latest source of radiophobia – Rainwater!

Fear of radiation in Japan has reached a new low. Now, it’s small, biologically-harmless amounts of radioactive material being flushed away by rainwater.


Last Sunday, a radiation monitor on a drainage ditch alarmed at Fukushima Daiichi. The alarm set-point for Beta-emitting isotopes, approved by the Nuclear Regulation Authority, was 1,500 Becquerels per liter. It reached 7,000 Bq/liter at the highest reading. Within 90 minutes, it had dropped back below the set-point. Tepco honestly reported that no tanks were leaking and no increase in the level of seawater activity had occurred. The company said they would investigate the source of the temporary activity spike.

On Tuesday, Tepco said they may have found the source of the sporadic alarm; a large puddle of rainwater that had accumulated on the roof of reactor building #2. The puddle’s activity was 23,000 Bq/liter. The outlet of the roof’s drainage gutter fed into the channel monitored by the device that alarmed. Plus, there were other puddles on the roof reading between 900 and 1,900 Bq/liter, but only one had enough activity to cause the monitor’s high reading on Sunday.

When asked by the Press, Tepco said that every time it rained the monitor showed an increase in activity, but this was the first time it alarmed. Further, while nearly all of the water passing by the monitor flowed through a bypass channel into the barricaded inner port, a small amount may have leaked by the closed gate leading directly to the sea. And, Tepco said it took about 90 minutes to close the gate isolating the channel from the inner port. This seems to be the point at which the feces hit the fan! The Press, as well as Tokyo’s Nuclear Regulation Authority, went haywire!

On Wednesday, the Mainichi Shimbun (one of Japan’s 5 largest newspapers) ran the report with the headline “Highly toxic water leaks into ocean from Fukushima plant”. The Mainichi claims there were actually 29,000 Bq/liter of cesium isotopes, and 52,000 Bq/liter of Beta emitters in the “puddle”, citing an un-named source at Tepco. Japan Times, one of the leading Japanese-American outlets, said, “The utility admitted Tuesday it failed to disclose leaks of rainwater containing radioactive substances from a drainage ditch at the stricken plant even though it was aware of high radiation in the water last spring.” The allegation of a cover-up is obvious. Even the usually-objective NHK World added to the fray, “TEPCO knew last April that the density of radioactive substances in the channel rose when rain fell. But it did nothing to prevent contaminated water from leaking directly out to sea, nor did it make the finding public.” Again, the implied supposition is “cover up”.

Fukushima’s fishermen also went ballistic, and the Press exploited it to the fullest. Japan Times reports that Masakazu Yabuki, chief of the Iwaki fisheries cooperative, said, “I don’t understand why (Tepco) kept silent even though they knew about it. Fishery operators are absolutely shocked.” Jiji Press adds that Soma-Futaba fisheries head says, “[Tepco] concealed the leaks into the ocean” and “Our relationship of trust has collapsed”. NHK World reports, “Fishermen are accusing the operator of the crippled Fukushima Daiichi nuclear power plant of betraying their trust.” In other words, allegations of cover-up abound among Fukushima’s fisheries.

In what seems to be another attempt to show it is in-charge, the Nuclear Regulation Authority demanded that Tepco thoroughly investigate the drain-leakage incident, which it seems the company was already doing. Adding insult to injury, NRA Chair Shunichi Tanaka said Tepco should not have allowed any contamination to drain to the plant’s port and a system of automatic gate closures should have been in place to stop flow if a monitor alarmed. In other words, Tanaka believes the rainwater incident is worthy of public concern and Tepco wasn’t professional enough to keep it from happening.

I guess it doesn’t matter whether or not an approved alarm set-point was breached. Every time it rains in Fukushima, raising the environmentally-innocuous level of contamination in the run-off, Tepco is supposed to shout it to the world! And, based on what we have seen the past few days, each declaration will be exaggerated by the Press with elaborated notions of “high toxicity”, and the local fishermen will scream bloody murder.

Radiophobia (mortal fear of radiation) infects millions, if not tens of millions of Japanese. Surveys show that 20% the public refuses to buy any foodstuffs coming from Fukushima Prefecture because it might contain an undetectable bit of Fukushima contamination. They believe that if it came from Fukushima, it is necessarily tainted…a term used incessantly by the Press when reporting on Fukushima.

Exploiting radiophobia is good for the news media business in Japan. Radiophobia is one of the core reasons Japan has a Nuclear Regulation Authority. Radiophobia is a real and present danger to the psychological health of the third largest economic entity in the world, but Japan’s Press and nuclear regulators don’t really seem to care. They exploit the fear-ridden millions with what is no less than reckless abandon.

The foundation of radiophobia is the belief that there is no safe level of radiation exposure. That is, all radiation exposure, no matter how trivial, poses a risk of inducing mortal cancer. No level of exposure is 100% safe, under this notion. However, no-safe-level is nothing more than a false belief. (click on “Radiation: The No-Safe-Level Myth” and “Science Proves ‘No-Safe-Level’ is a Fiction”, in the left-hand column) However, the scientific truth about the safety of low level exposure is nowhere to be found in the Japanese Press, and the NRA is clearly an accomplice to this informational omission.

What about the impact by the alleged leak on the Pacific Ocean? None of the numerous sampling points inside the F. Daiichi port’s break-wall show one iota of radiological impact. Ditto for those taken outside the break-wall, including the sampling point nearest the old, now-isolated drain discharge directly to the sea. It has been this way since the sporadic, non-alarmable fluctuations in the discharge channel have occurred since last April. But, this doesn’t matter to the Press or the NRA.

It seems that every time it rains in Fukushima, Tepco will be forced to warn everyone that an ensuing, harmless-but-detectible release of radioactive rainwater run-off is possible. The Press will post exaggerated copy of toxicity and the NRA will tell Tepco to do the job it is already doing. As a result, Japan’s millions within the radiophobic demographic are having their existent nuclear stress amplified by a new, entirely unnecessary source of angst…rainwater!

Fear of radiation the only thing stopping discharge of Fukushima wastewaters

This week, the head of the IAEA Fukushima inspection team urged Tepco to release fully treated Fukushima wastewaters to the sea. At a news conference in Tokyo, Juan Carlos Lentijo said, “Controlled discharges are a normal practice in the industry. Most of the [world’s] nuclear power plants are discharging treated water. This is accomplished with negligible impact on the environment and the safety of the people.” The head of Japan’s Nuclear Regulation Authority, Shunichi Tanaka, said essentially the same thing last month. In response to a worker falling to his death while fabricating yet another giant storage tank, Tanaka asserted, “Tokyo Electric Power must consider whether it (storing the water) is really necessary. It is surely harmful if it leads to the death of workers. It is important to listen to public opinion, but human life must not be lost for the sake of echoing public views. You [Tepco] are not yet demonstrating appropriate determination.”

All waste waters are run through what is essentially a three stage process to remove radioactive isotopes. The first is a cesium absorption system that has worked better than expected. It was hoped it would have a removal factor of 1,000, but has actually had a Cesium decontamination factor of more than 10,000. The next stage is called ALPS; Advanced Liquid Processing System. ALPS strips the water discharged from the Cesium absorbers of all additional radioisotopes, except one – Tritium. Since ALPS’ output has a tiny amount of radioactive Strontium in it, Tepco recently added a mobile Strontium removal system as the final step in the process. All that remains is water… Water so chemically pure it rivals that used in research facilities. Water so chemically pure it would probably not conduct electricity!

One might ask, what about the Tritium? Tritium is hydrogen, albeit the element’s radioactive isotope. The Tritium is an integral part of water molecules in the storage tanks, just the same as the non-radioactive isotope of hydrogen found in all water molecules of the universe. Tritium is also biologically innocuous; i.e. it will not harm organisms. (For more detail, click on “Background Information on Tritium” in the left-hand column)

In the best of all possible worlds, and in any other country on our planet, the Tritium-only waters would already have been dumped into the Pacific Ocean, and the unfortunate death of the plant worker last month would never have happened! But, Japan is not the best of all possible worlds when it comes to radiation. In fact, it may well be the worst!

Unbridled fear of radiation (radiophobia), no matter how trivial, infects millions of Japanese citizens. If radiation is detectible, it is unacceptable. The Japanese Press continually uses the term “tainted” to describe any waters found to have radioactive isotopes in it, or have had contamination in it. Thus, the Press recurrently reinforces radiophobia in the minds of those so-afflicted. In fact, the mere possibility of radiation triggers this paranoiac aversion.

Less than 48 hours after NRA Chair Tanaka urged Tepco to discharge fully-treated waters, the Fukushima Fisheries demanded this not happen. Why? Because it would possibly further hurt sale of their catches in Japan’s large marketplaces. Surveys show that as much as 20% of the public shuns any foods coming out of Fukushima Prefecture, whether or not it contains detectible contaminants. It doesn’t matter that all Fukushima foods must pass the most stringent marketing restrictions in the world. The food might have some radioactive material in it that is too little to be detected. After all, if it’s from Fukushima, it must be tainted. This is why the Fukushima Fisheries are convinced that releasing the tritiated waters to the sea would make a bad situation worse.

Unfortunately, they are probably right.

A Japanese colleague who lives in Japan says fear of radiation has infected the island nation since the bombing of Hiroshima in 1945. He says millions believe that all of the people killed at Hiroshima and Nagasaki were due to fallout; i.e. they all died due to radiation exposure. Actually, of the 200,000 who died due to the nuclear bombings, more than 97% were due to the two horrific explosions, and not due to radiation. It seems that Japan’s government neglected to tell its people this simple fact and it has become a foundation of the country’s current fear of radiation, exacerbated by a complete lack of education about radiation over the past seven decades!

This is my fourth Fukushima Commentary posting on the matter. My first “A Plea to Tepco and Tokyo – Just Do It!” was on 9/27/14, the second “Radiophobia increasing in Japan’s markets (again)” on 10/8/14, and the next was “Japan’s NRA chief is right: Tepco should release water ASAP” on 1/28/15. If this is beginning to sound like a stuck record, so be it. Franklin Roosevelt once said the only thing we have to fear is fear itself. It seems that such a concept is alien to Japan’s numerous radiophobic demographic. Tepco seems more concerned about catering to their unfounded fears than releasing the entirely harmless wastewater to the sea.

Japan’s NRA chief is right: Tepco should release water ASAP

On January 21, Chairman Shunichi Tanaka of the Nuclear Regulation Authority spoke about the worker safety issue at Fukushima Daiichi following the death of a contractor employee. The employee slipped and fell from the top of a ten-meter high tank while helping secure the top cover of the container. Tanaka said one of the causes was Tepco continually building more and more tanks to store contaminated and decontaminated waters. He reiterated his opinion, made a few days earlier, that fully treated water should be released to the sea, as long as all radio-isotopic levels are below permissible limits.

Tanaka’s original statement caused a negative outcry from some of the public, and Fukushima fishermen, who did not want the releases to happen. The public reasoning was that even if contamination is well-below national standards, some radioactivity could remain and any detectible amount is unacceptable. The fishermen balked at Tanaka’s suggestion because any release to the sea could further damage the sale of Fukushima seafood in the marketplace.

After Tanaka’s January 21st restatement of his position, members of the public and Press in attendance shouted their continued disapproval. He responded with anger, “Even if a person dies?” He then turned to the Tepco Chairman and said,“It is important to listen to public opinion, but human life must not be lost for the sake of echoing public views. You are not yet demonstrating appropriate determination.” (1)

It should come as no surprise to regular readers of these blogs that this writer is not a big fan of Tanaka. However, in this case I must give him a hearty “well done”! About half of the 400,000 tons of wastewater stored at Fukushima Daiichi has been run through the multi-system decontamination process and cleansed to a purity approaching near-laboratory quality. Tepco has already said that any release will be run through mobile Strontium absorbers one final time to insure that the only radio-isotope remaining is Tritium, which is part of the water molecule itself. As I have written on many occasions, Tritium is biologically harmless.

To make the outcry from the public and Press even more ridiculous, Tepco has self-imposed limits that are ten to 15 times lower than Japan’s ultra-conservative drinking water standards. Further, this water will be released into the Pacific Ocean; not into a drinking water supply! And, no one drinks seawater, anyway! It seems that some segments of the Japanese public and Press believe that miniscule hypothetical risks are more important than human life!

Is Tepco taking heed of the NRA Chair’s admonition? It seems not! It appears Tepco is entirely comfortable with building more and more storage tanks, at considerable cost. They have ceased all decommissioning and recovery work at F. Daiichi until all worker safety considerations are checked and all contractors are fully trained in safety. This is also costing considerable time and money. However, the loss of life, as well as subsequent expenditures for upgraded worker safety, could have been easily avoided if Tepco had shown “appropriate determination” a long time ago and discharged the fully treated waters to the sea.

Yes…I’m mad as a wet hornet about this, and have been since word of the employee’s unfortunate demise hit the news last week. I called for Tepco to begin discharges to the sea in my September 27 Commentary; “A Plea to Tepco and Tokyo: Just Do it!” (2)  NRA Chair Shunichi Tanaka is telling Tepco to do the same thing., and start the discharges as soon as possible, before someone else gets hurt.

Fact or Fiction (?) quiz answer – Fiction. Fermi did win the Nobel Prize, but it was not in 1942 and it had nothing to do with the Chicago Pile. Actually, he won the prize in 1938 for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons".

Japan NRA Chief makes no sense about nuke restart safety

Japan’s chief nuke watchdog says 2015 will be a crucial year for nuke safety. Nuclear Regulation Authority Chairman Shunichi Tanaka made his first Press statement of the year on January 6th. He said restarting nukes face particularly dangerous risks of accidents. Tanaka gave two reasons for his statement. First, the units have been idled for a long time. Second, they have a lot of new safety equipment never used before. (1)

Both of his reasons make little or no sense.

Yes, the 48 mandated-idled units have not run in a long time, the most recent shutdowns being the two Oi units in September of 2013. Many others have been off for two years or more. Tanaka makes it seem that all idled units have been left alone and the crews have taken a “Well, we’re shut down. Who’s got a deck of cards” attitude. As a veteran of 15 years in construction and commercial operation of an American nuke, I know that Tanaka’s implied concept is simply not the case.

All of the currently-idled nukes were either already in a refueling outage or subsequently went into one when shut down by Naoto Kan’s moratorium. With any refueling outage, considerable activity occurs to insure that a subsequent start-up will occur safety and expeditiously: e.g. systems are tested, planned maintenance is performed as scheduled, and operation’s systems are kept in peak condition. Since this is actually an extended refueling outage with respect to the systems needed for restarts, the passage of time should not make future nuke restarts any different than the routine startups experienced after every refueling period.

With respect to Tanaka’s second reason, the new safety equipment for each Japanese nuke has essentially nothing to do with the operating systems on any of the 48 units. They are not involved with actually restarting the units. The new safety equipment is specific to making sure another prolonged full-station-blackout, a-la Fukushima Daiichi, does not happen again. The emergency systems are there to keep emergency electricity flowing into a plant in the event that another beyond-worst-case natural disaster happens. The equipment has nothing to do with routine startup and operation of the power plant.

Thus, we need to ask; what would possess Tanaka to believe these two things? I can only think of two possibilities. One is that he isn’t knowledgeable in power plant operations. Although he has nuclear engineering credentials and a long history in nuclear academia, his resume’ does not include any power plant operating experience. It seems he has university and research-level reactor experience, but that is a far cry for a large power plant reactor’s operations. I like to say it’s as different as operating a compact car versus a top-fuel dragster. It would be nice to think Tanaka understands operations at nuclear power plants, but his statements indicate otherwise. 

The second possibility is that he thinks he’s demonstrating informational transparency. But, does this include making inexperienced suppositions that can only increase fear in a largely naïve public? I think not. In the words of a famous (now deceased) American sportscaster, “Tell it like it is!” That’s transparency in a nutshell. Don’t tell it like it isn’t! Tanaka’s notion of “particularly dangerous risks of accidents” due to nuke startups is anything but a demonstration of transparency.

To the contrary, it’s a demonstration of naivety.
