A series of defective products at a French MOX fuel plant Abnormal nuclear reaction at a nuclear power plant
September 3, 2022
A series of defective products have been found at the Mellox plant in southeastern France, which manufactures fuel for plutonium thermal power generation, in which plutonium is burned in nuclear power plants. In addition, an abnormal increase in nuclear reactions has also been observed at some nuclear power plants that are conducting plu-thermal power generation. What in the world is going on?
The plant also manufactures fuel for the Japanese market. No problems have been found so far with the fuel for the Japanese market, but production has been delayed, and future product deliveries are now unpredictable.
Plutonium is extracted from spent nuclear fuel from nuclear power plants through chemical processing (reprocessing). Plutonium is mixed with uranium in the case of pressurized-water nuclear power plants that conduct plutonium thermal power generation, and baked into pellets, cylindrical grains about 8 mm in diameter. This is called mixed uranium-plutonium oxide fuel (MOX fuel). In the case of a pressurized-water nuclear power plant that conducts plutonium thermal power generation, approximately 320 pellets are stacked inside fuel rods, and another 260 fuel rods are bundled together to form a fuel assembly (approximately 4.1 meters in height).
Highly Difficult Homogenization
It is difficult to uniformly mix plutonium and uranium. According to ASN data and other sources, “plutonium spots,” dense clumps of plutonium, were found in the fuel pellets produced at the MELOX plant. Plutonium spots were found in the fuel pellets manufactured at the MELOX plant.
On the other hand, a phenomenon in which the amount of neutrons, which indicate a nuclear reaction, increases more than expected near the upper and lower ends of MOX fuel rods was confirmed at a French nuclear power plant conducting a plutonium thermal operation.
According to ASN, the combination of this plutonium mass problem and the two anomalies of partially elevated nuclear reactions was predicted to “raise questions about the integrity of the fuel, depending on the circumstances of the accident.
According to Chihiro Uesawa, 56, an engineering specialist at the NPO Nuclear Information and Data Center (Nakano Ward, Tokyo), concerns are that the fuel could melt or the tubes covering the fuel could break. When plutonium is used as fuel, it has been pointed out that there is a possibility of a localized increase in nuclear reactions. This has become apparent,” Uesawa said.
Japan to Give Plutonium from Spent Fuel to France
June 21, 2022
Tokyo, June 21 (Jiji Press)–The Japan Atomic Energy Agency will give France plutonium extracted from spent nuclear fuel from its Fugen advanced converter reactor, officials have said.
The agency will conclude a contract with a French nuclear company this month at the earliest, according to the officials.
The French side is expected to reprocess the spent nuclear fuel from the reactor, which is in the decommissioning process, in the central Japan prefecture of Fukui.
On Wednesday, the Japanese and French governments exchanged notes on the transportation and reprocessing of spent nuclear fuel and the return of high-level radioactive waste to Japan.
The two sides agreed to start the removal of 731 spent nuclear fuel assemblies from Fugen in April 2023 and complete the work by the end of March 2027.
Fukushima and freedom of expression
September 23, 2020
According to Asahi, guides welcoming visitors to the disaster museum, which opened on September 20 in Futaba, have no right to criticize either TEPCo or the government. The 29 guides are victims of the disaster or trained people. Each guided tour lasts one hour and is paid 3,500 yen.
During the trainings that took place this summer, the distributed manual stated that one should avoid “criticizing or defaming certain organizations, people or other facilities”. And if a visitor asks the guide about their feelings about TEPCo’s responsibility, the answer should be evasive and the visitor referred to museum staff. Each guide must also put his words in writing and submit it to the museum management who corrects it. And if they ever criticize an organization, their presentation will be immediately stopped and they will never be able to be a guide in that museum again.
Some guides took offense: as victims, they should be able to criticize TEPCo and the government, which are responsible for the nuclear disaster. Another guide saw their script corrected after mentioning this responsibility. Yet official investigative reports pointed to the responsibility of TEPCo and the government. Not being able to mention it in a museum dedicated to the nuclear disaster is scandalous.
Ironically, Le Canard Enchaîné published an article that same day on the dismissal of an IRSN researcher who was working on the consequences of the Fukushima disaster and who did not agree to have her work censored by his hierarchy. In response, ACRO left the Research Orientation Committee (COR) of this Institute. The resignation letter is on the association’s website and reproduced below.
According to Le Canard Enchaîné, the direct superior of Christine Fassert, the licensed researcher, “wanted to impose changes, even censor words and sentences [of] an article,” in order to “avoid criticism of post-management. accident of the Japanese government, and the civilian nuclear sector in general “, and” to minimize and relativize the risk related to radiation exposure “.
This event is very disturbing because it shows that IRSN is unwilling to accept research results that challenge its prejudices. And when you’re in charge of nuclear safety, it’s particularly serious. He is not the only person to have suffered the rigidity of this institute, but it is the first time that it has led to a dismissal, which is scandalous.
We have already emphasized, twice, in July 2018 and March 2019, the originality of the work of Christine Fassert, socio-anthropologist, risk specialist at IRSN, who worked on trust, as part of the Shinrai project. in partnership with Sciences Po and Tôkyô Tech University. In Japan, as in France, she went, with her Japanese colleagues, to meet all the protagonists and interviewed both officials and independent experts, as can be seen in this presentation (copy).
At IRSN, we prefer to focus on people who show that it is possible to live in contaminated areas. And the dominant paradigm is that we must avoid evacuating and bringing evacuees back as quickly as possible, bypassing the UN directives on internally displaced persons which guarantee them protection, the right to choose between return and resettlement, as well as their full participation in decisions (see our 2016 report: Fukushima, return to abnormal?). It is also obvious in the European research programs in which IRSN participates, where the reduction of uncertainties in the modeling of radioactive fallout should make it possible to avoid unnecessary evacuation of populations (see page 58 of this presentation, for example) , while the faults in the modeling in Fukushima also led to not evacuating people who should have been! This is the case for the contaminated territories which extend up to forty kilometers to the Northwest. The evacuation order did not arrive until April 22, 2011, when the disaster began on March 11, 2011.
In practice, IRSN did not hesitate to work on and highlight an unscrupulous researcher, as we reported in January 2019, but who said what the institute wanted to hear. This is also the object of the Fukushima “dialogues” supported by IRSN shown in the web documentary “Kotoba” (which means “word” and not “dialogue”): no radioactive waste, no sick, no residents who don’t want to come in… Just a few small worries, but in twelve “dialogues”, everything is settled! The results of these dialogues by IRSN are a distressing list of banalities. This is worrying for post-accident management in the event of an accident in France.
Christine Fassert, for her part, also went to meet people who have left and who do not want to return, giving visibility to a category of populations that everyone wants to ignore, although it is the most numerous. The project also examined the pitfalls of an essentially “reassuring” communication on radiological risk, the difficulty of the role of radiation protection experts in direct contact with the public, the tension between a government policy of evacuations and returns devised by Tokoite elites and the implementation of these directives by the mayors in the region of Fukushima… Only subjects which did not fall within the narrow framework of what was expected. So, it was the frame or her!
Resignation message sent on September 18, 2020 to COR members:
Madame President,
Following the dismissal of an IRSN researcher, I would like to resign from COR. If the IRSN is not able to accept unique voices internally, it cannot open up to society.
In its opinion on the post-accident, the COR stressed, for the “populations and governance” section: “The WG thinks that it would be important to conduct research on this subject taking into account the opinions of all categories. population. Self-evacuees escape official monitoring in Japan and most of the studies and research in which IRSN participates. The experience feedback cannot be limited to the population who wish to remain in place or return, which is not very representative of all the populations affected by a serious nuclear accident. IRSN would benefit from broadening the scope of its studies and research or from moving closer to other programs involving all the people affected by the disaster, including those who do not wish to stay or return. “
In the event of a nuclear accident in France, IRSN will not be able to choose from among the affected populations. The participation of all stakeholders will be necessary. The licensed researcher is precisely the only person at the institute who was interested in all categories of the population, the “dialogues” program having selected only people in agreement with the dominant paradigm at IRSN.
I have already had the opportunity several times, within the COR, to question and alert IRSN researchers on the freedom to publish and communicate, to no avail. The COR has never agreed to discuss it.
Since the beginning of COR, I have worked for more openness and to take into account the demands of society. I have participated in almost all GTs and chaired two of them. But I fear that all this work has been in vain and that IRSN is not ready to open up sincerely. Under these conditions, I see no other solution than to resign from COR.
Yours truly,
David Boilley

Sixth MOX nuclear shipment leaves France for Japan
Protesters say the nuclear shipment is too dangerous
A cargo of reprocessed nuclear fuel containing highly radioactive plutonium left the French port of Cherbourg for Japan under heavy security on Wednesday as demonstrators protested against the transport.
The controversial shipment from a plant of the French nuclear group Areva located some 20 kilometres (12 miles) away arrived at the port before dawn aboard two trucks escorted by dozens of security vehicles as a helicopter flew overhead.
Around 20 Greenpeace activists carried protest banners and threw smoke bombs at the convoy shortly before it arrived at the port.
It is the sixth shipment of mixed oxide (MOX), a blend of plutonium and uranium, from France to Japan since 1999.
“We are warning of how dangerous this shipment is and especially the risk of nuclear proliferation and the possible diversion for military purposes,” Greenpeace France activist Yannick Rousselet told AFP.
Areva spokesman Alexandre Marinot described the cargo as being of “a maximum safety level.”
Uranium reactors produce a mixture of depleted uranium and plutonium as a by-product of fission. These can be re-processed into MOX fuel, which can then be used in other reactors to generate more power.
Japan has few energy resources of its own and relied on nuclear power for nearly one-third of its domestic electricity needs until the 2011 meltdowns at the tsunami-crippled Fukushima plant.
On Tuesday, the Reseau Sortir du Nucleaire (Nuclear Phase-Out) said in a statement: “Areva profits from selling this dangerous fuel to a country devastated by a nuclear accident to supply reactors whose resumption the Japanese people reject.”
There are currently five reactors in operation in Japan compared with 54 before the Fukushima accident.

Japan, France confirm nuclear and security cooperation
PARIS (Kyodo) — Japanese Prime Minister Shinzo Abe and French President Francois Hollande on Monday confirmed bilateral cooperation in the research of the commercial use of nuclear power as well as in security.
The two countries agreed on joint research on a French-led fast reactor development project called ASTRID, an acronym for Advanced Sodium Technological Reactor for Industrial Demonstration.
As the leaders met, Japanese industry minister Hiroshige Seko, who is accompanying Abe, and French environment minister Segolene Royal signed a nuclear power cooperation agreement, stating that they will work together on nuclear fuel cycle and fast reactor development.
France aims to start the operation of ASTRID in the 2030s.
Abe and Hollande also attended a signing ceremony on a deal in which Mitsubishi Heavy Industries Ltd. and Japan Nuclear Fuel Ltd. will each acquire a 5 percent stake in a nuclear fuel reprocessing joint venture to be established by French atomic energy company Areva.
In the sphere of security, Abe revealed to reporters after the talks with Hollande that Japan’s Maritime Self-Defense Forces will jointly conduct naval exercises with France, the United States and Britain.
The Japanese premier welcomed the “significant” agreement on the exercises to be held in the Asia-Pacific region, including off Guam in the Western Pacific, apparently in view of China’s expansionary maritime activities.
The Japanese leader said he and Hollande shared a view that the Indian and Pacific oceans are international public goods and need to be maintained as free and open areas.
Abe said a French training squadron, including a helicopter carrier, will visit Japan in late April.
On regional issues, Abe strongly condemned North Korea’s nuclear and missile programs, while Hollande expressed Paris’ support for Tokyo on the matter.
It was the 10th and final meeting between Abe and Hollande as the latter is not running in France’s upcoming presidential election. The first round of the election is in April followed by a potential runoff vote in May.
As for economic issues, Abe and Hollande agreed on the importance of promoting free trade amid the threat of rising protectionism across the world following the inauguration of U.S. President Donald Trump.
They affirmed cooperation for the early signing of the free trade agreement between Japan and the European Union.
Abe expressed Japan’s support for “a strong Europe” to be maintained even after Britain’s forthcoming exit from the bloc.
“Japan and Europe must fly the flag of free trade high, together with the United States,” Abe said.
Hollande said the Japan-France relationship can be further strengthened.
France’s election is one of a series in Europe this year in which public unease about immigration and the functions of the European Union have fuelled speculation voters could pick populist candidates over the current political establishment.
Abe arrived in Paris on Monday after talks with German Chancellor Angela Merkel in Hanover. He is scheduled to meet European Council President Donald Tusk and Italian Prime Minister Paolo Gentiloni before returning to Japan on Wednesday.

Five French nuclear reactors with Japan-made parts ordered to undergo safety tests ahead of schedule
Some Japanese reactors also used steel from JCFC, according to statements from the companies:
- Tokyo Electric Power Co. Holdings Inc.’s Fukushima Dai-2 No. 2, No. 4
- Kansai Electric Power Co.’s Takahama No. 2, Oi No. 1 and No. 2
- Kyushu Electric Power Co.’s Genkai No. 2, No. 3, No. 4, Sendai No. 1, No. 2
- Shikoku Electric Power Co.’s Ikata No. 2
- Hokuriku Electric Power Co.’s Shika No. 1
- Japan Atomic Energy Agency’s Tsuruga No. 2
France’s Nuclear Safety Authority has ordered the country’s EDF utility to conduct checkups at five nuclear reactors ahead of their scheduled maintenance tests, citing potential weakness in critical parts manufactured by a Japanese company, French media reported Tuesday.
All five nuclear reactors are using parts made by Kitakyushu-based Japan Casting & Forging Corp. (JCFC), which is now under scrutiny by Japan’s Nuclear Regulation Authority.
The NRA discussed the matter at its regular meeting on Wednesday as it has also found the company manufactured reactor pressure vessels in 13 Japanese nuclear reactors including the Sendai Nos. 1 and 2 reactors operated by Kyushu Electric Power Co. in Kagoshima Prefecture.
The Sendai No. 1 reactor is undergoing a regular checkup while the No. 2 reactor is in operation.
In addition, the NRA said JCFC had been manufacturing important components at the No. 2 unit at Kansai Electric Power Co.’s Mihama plant in Fukui Prefecture and No. 1 unit at Kyushu Electric Power Co.’s Genkai nuclear plant in Saga Prefecture, which have already been decommissioned.
The French nuclear watchdog ASN said earlier in June that parts manufactured by JCFC using a method called “forging,” in which metals are hammered and extended, contained a high carbon concentration that could lead to lower-than-expected mechanical strength.
In the documents submitted to the NRA meeting, JCFC admitted there is a possibility that the parts used in nuclear power plants in France contain carbon higher than the regulated limits, but parts used in Japan are manufactured after removing high-carbon concentration from steel.
According to the media reports, safety tests have already been carried out at seven of a total of 12 reactors in France that used parts manufactured by JCFC. Parts at four of the seven reactors are believed to contain a higher carbon concentration than permitted by standards.
Following these findings, ASN told EDF to test the remaining five reactors within three months.
France has 58 commercial nuclear reactors. At the No. 3 reactor at Flamanville nuclear plant, which is under construction, parts made in 2014 by Creusot Forge, a subsidiary of France’s Areva SA, were found to be lacking in strength. ASN later discovered that the parts manufactured by JCFC also had problems.

Ministries spar as Japan focuses on fast reactor project in France
The industry and science ministries were at odds over Japan’s shift toward France for nuclear fuel recycling efforts after Tokyo decided to scrap a “made-in-Japan” pillar of its energy policy.
The industry and science ministries were at odds over Japan’s shift toward France for nuclear fuel recycling efforts after Tokyo decided to scrap a “made-in-Japan” pillar of its energy policy.
Hiroshige Seko, minister of economy, trade and industry, stressed the significance of working with France, a global leader in fast reactor technology, after a Sept. 21 meeting of Cabinet members agreed to terminate the problem-stricken Monju prototype fast-breeder reactor project.
Seko told reporters that his ministry, which is in charge of the nation’ s energy policy, is pinning its hopes on joint research, including France’s ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) fast reactor.
“ASTRID is a crucial project for both Japan and France,” Seko said. “Japan has already participated in the project and has obtained various insights.”
The Monju fast-breeder reactor and the ASTRID fast reactor use similar technologies but are different.
Monju was designed to use plutonium as fuel for electricity generation and to produce more plutonium in the process.
ASTRID is centered on generating energy by consuming plutonium.
In addition, ASTRID is at a more advanced development stage than Monju.
There are four stages in the development of a nuclear reactor: experimental, prototype, demonstration and commercial.
ASTRID is in the demonstration stage while Monju is a prototype reactor.
Japan and France are already cooperating in the field of nuclear energy.
Prime Minister Shinzo Abe agreed that Japan would cooperate with France on preparations for a fast reactor project when he met with French President Francois Hollande in June 2013.
The two countries also concluded a tie-up in technological development and cooperation for fast reactors, including ASTRID, in May 2014.
“Prospects are brighter than Monju, and France is a reliable partner,” said an industry ministry official.
But the science ministry, which has clashed with the industry ministry over the fate of Monju, is skeptical.
It says the France-led project does not necessarily promise success, citing Super-Phenix, France’s demonstrator fast-breeder reactor that was forced to shut down after a series of accidents, including a sodium leak, like Monju.
The science ministry has oversight in the first two stages of reactor development, while the industry ministry takes over for the two more advanced stages.
ASTRID is expected to go into operation in the 2030s, but the science ministry said that schedule could face delays.
Sources familiar with the project also say ASTRID will likely cost more than initially expected.
“Japan could end up serving as a cash cow,” a senior science ministry official said.
However, the industry ministry is not budging on its stance.
“What matters is that Japan keeps alive its research on a fast reactor,” a high-ranking ministry official said. “Japan should not dwell on a home-grown project.”
Nuclear Repression, not Nuclear Renaissance, in Jaitapur, India
Jaitapur’s people are more concerned about being treated as sub-humans by the state, which has unleashed savage repression, including hundreds of arrests, illegal detentions and orders prohibiting peaceful assemblies. Eminent citizens keen to express solidarity with protesters were banned, including a former supreme court judge, the Communist party’s secretary and a former Navy chief. Gadgil too was prevented. A former high court judge was detained illegally for five days. Worse, a Maharashtra minister recently threatened that “outsiders” who visit Jaitapur wouldn’t be “allowed to come out” (alive).

French nuclear firm stuck, unable to sell nuclear reactors in USA
EDF Puts U.S. Nuclear Expansion Plans on Hold, BloombergBy Tara Patel – Nov 16, 2010 Electricite de France the biggest operator of nuclear reactors, put on hold a plan to develop atomic plants in the U.S…. EDF is reviewing its business in the U.S. and supply contracts for developing a reactor, Thomas Piquemal, chief financial officer, said today on a conference call. “When we have a better visibility on the regulatory environment and price evolution, we will be in a better position to see whether we go ahead with U.S. projects.”
EDF agreed last month to pay about $249 million partly to buy out Constellation Energy Group Inc. from a venture to develop EPR reactors in the U.S., including one in Maryland. Slumping power prices has cut the value of three U.S. atomic plants that the two utilities own together and forecasts of sustained low prices prompted Constellation to withdraw from talks on a government loan guarantee for the Maryland reactor…..
