Dear Frédéric Patalagoity,
We are writing to you to express our disappointment and concerns over the use of AREVA produced MOX fuel in Japanese nuclear power plants.
As you know we wrote to you on January 28th of this year to request details over the quality of plutonium mixed oxide fuel supplied to Japan, specifically Kansai Electric. We have yet to receive a response to this letter (also attached to this letter).
As you will be aware the Ikata 3 reactor is due to restart operations shortly. Sixteen assemblies of MOX fuel supplied by AREVA in 2009 (as part of 21 assembly delivery) have been loaded into the reactor. As with the fuel supplied to Takahama, there are major doubts over the safety of the MOX fuel about to be used in Ikata, including quality control issues related to the thermal stability of the fuel.
We are alarmed by the lack of transparency over issues of fundamental nuclear safety demonstrated by AREVA’s lack of response. At a time of unprecedented crisis for the global business operations of AREVA, failure to provide information that is in the public interest and that of nuclear safety is both unacceptable and poor business practice. Once again we calling on AREVA to release immediately the actual quality control data for MOX fuel assemblies supplied to both Kansai Electric’s Takahama 3&4 reactors, and Shikoku Electric’s Ikata 3 reactor.

Dear Frédéric Patalagoity,
We are writing to you to outline our concerns with the production standards, quality control and, ultimately, safety of AREVA plutonium MOX fuel produced for Japanese utilities. Specifically the planned use of 30 MOX assemblies in the Takahama reactor units 3&4, owned by Kansai Electric.
As you will be aware it is fifteen years since the poor quality control and production standards of plutonium MOX fuel was first disclosed in the case of 8 MOX fuel assemblies manufactured by the then British Nuclear Fuels Limited (BNFL) at Sellafield in the UK, and delivered to the Kansai Electric reactor Takahama unit 4 in Fukui prefecture. As a result of our analysis, based on original quality control data that BNFL were forced to disclose publicly at that time, Green Action and Mihama-no-Kai filed a legal challenge. For two month both Kansai Electric and BNFL denied that the fuel had falsified quality control data. However, in December 1999, one day before the court ruling, Kansai Electric and BNFL were forced to confirm in that plutonium MOX fuel to be used in Takahama 4 contained falsified quality control data. As you know the fuel was returned to the UK and scrapped.
In 1999 and 2000 we produced analysis that showed production and quality control standards for MOX fuel produced using the MIMAS method, including at the Cogema/AREVA Melox plant, were actually of a lower standard than used by BNFL. This was used by a legal challenge to the Fukushima District court on behalf of 1000 plaintiffs in challenging the loading of 32 MOX fuel assemblies into the Fukushima Daiichi unit 3 reactor. The MOX fuel was manufactured using the MIMAS method, under a contract between Tokyo Electric and COMMOX, of which Cogema was a lead agency. While the judgement of the Fukushima District Court did not uphold the lawsuits complaint, the judgement also made clear that quality control data for the MOX fuel should be publicly disclosed. No such data was released by COMMOX in the intervening years. As a consequence of the doubts and controversy over the safety and quality of MOX fuel, Tokyo Electric were prevented from use of the 32 assemblies of MOX fuel until September 2010, six months prior to the March 2011 disaster.
You will also be aware that 28 MOX assemblies delivered to the Kashiwazaki Kariwa nuclear plant in Niigata in 2001, as a consequence of the controversy over the quality and safety of MOX fuel and the opposition of the people of Kariwa, was not loaded into unit 3 as planned. Nearly 15 years later that plutonium fuel remains unused and stored in the cooling pool at the reactor site.
As AREVA sought to restart its MOX business with Japanese utilities the issue of quality control and production standards persisted. Twelve AREVA MOX fuel assemblies, containing 552kg of plutonium were delivered to the Takahama plant in 2010, eight of which were loaded into unit 3. Our analysis at the time found that there were disagreements between AREVA and Nuclear Fuel Industries Ltd (the developer and design code verifier of the MOX fuel and contractor acting on behalf of Kansai Electric and other Japanese power companies). Specifically over the MOX fuel quality and production standards to be used for the manufacture of Japanese fuel at AREVA’s Melox fuel production plant in Marcoule, France, including for Takahama. As a result of AREVA’s production problems, and their intransigence, NFI agreed to AREVA’s insistence that a lower standard of production and quality control would be used for the production of MOX fuel, including for that produced for Kansai Electric. AREVA failed to publicly provide quality control data at this time when challenged by us in 2010.
As you know the safety implications of MOX fuel use are severe. This is made worse by significant problems with the quality control and production standards that exist at the Melox plant.
The MIMAS production technology used at Melox has a multiple problems, including in relation to a fundamental issue for MOX fuel, Thermal Stability. If the plutonium fuel pellets swell under heat alone, and as internal pressure builds up from gaseous fission products, a gas-filled pellet-cladding gap can occur. This has several nuclear safety consequences. Not least that in the event of a loss of coolant accident, the MOX fuel, which may already be fractious, would be further more likely to fragment and “relocate”. The heterogeneous fuel structure can also increase the chance that fuel rods will rupture and block coolant channels if a transient occurs, again potentially impacting cooling function of the reactor core. The reactor safety implications of not being able to sufficiently cool the reactor core fuel are obvious, not least from the meltdown of three reactors at Fukushima Daiichi in 2011. This underscores the importance of achieving the highest nuclear fuel production standards, and applying the most rigorous quality control and inspection. Neither of these are possible at the Melox plant.
The thermal stability problem that exists with Melox produced MOX fuel is but one of multiple concerns we have with plans to operate Japanese reactors with AREVA supplied fuel. The fact that five years after delivery of MOX fuel to Takahama, AREVA has made no effort to provide details on their production and quality control standards is unacceptable to the people of Japan. Already subjected to the consequences of the Fukushima Daiichi accident, the people of Japan are now confronted with the risks of the restart of the Takahama reactor units 3 and 4, to be operated with 24 assemblies and 4 assemblies of AREVA MOX fuel, containing 1,088kg and 184kg of plutonium respectively.
The failure of the Japanese Nuclear Regulation Authority (NRA) to re-assess the risks of MOX fuel use in Japan is deeply regrettable and we have challenged them on this, relying as they do on the reviews conducted by the discredited NISA. At the same time, AREVA as the manufacturer of this substandard product, has a duty to publicly disclose all relevant and original data on the quality control and production standards of its fuel that is about to be used in the Takahama reactors.
It is all the more critical that AREVA release the quality control data for the Takahama MOX fuel, as in 2010 the French nuclear safety regulator, ASN, confirmed to Greenpeace France in relation to the fuel then being shipped to Japan for use in Takahama unit 3, that, “The ASN is not involved in the quality control of production destined for Japanese utilities.” With neither French or Japanese regulators overseeing MOX fuel standards and quality control there clearly are additional major failures and risks from Kansai Electric’s plans to use AREVA MOX fuel. Without a commitment to transparency on this issue, assurances that the fuel is safe to use are meaningless.
We understand that AREVA have multiple threats and challenges to their future business prospects. Securing additional MOX business with Japanese utilities, including new MOX fuel manufacture, must rank high in your priorities given the 16,000kg of plutonium belonging to Japan currently stored in France. This will require the transport of many hundreds tons of MOX fuel from France, including that scheduled for 2016. But we would contend that a failure to put safety first and above commercial interests is in no ones interests, including those of AREVA.
Conducting a nuclear test on the people of Fukui, Kansai region and wider Japan, is never acceptable. As we approach the anniversary of the Fukushima Daiichi accident it is even more reprehensible that AREVA has so far refused to fully disclose all relevant data on its MOX production problems at Melox. We are calling on you to release immediately the actual quality control data for the 30 MOX fuel assemblies about to irradiated in the Takahama reactors.

Plutonium Shipment to Depart Japan for United States – Exposes Failure Of Global Reprocessing Programs
March 22nd 2016, Tokyo…The shipment of weapons-grade plutonium at the port of Tokai, Ibaraki prefecture departing later today, exposes the failure of global plutonium reprocessing programs and the threat from current Japanese nuclear policy, five non-governmental organizations charged today.(1) The cargo of 331kg of plutonium was loaded on to the Pacific Egret, an armed British nuclear transport ship, after it arrived at Tokai at 08.00 March 21st. Armed Japanese coastguard vessels, including the Shikishima, are outside the port and are expected to escort the plutonium shipment while inside Japanese coastal waters. The shipment is being undertaken in a failed U.S. policy attempt to reduce the threat from nuclear weapons materials worldwide.
The plutonium cargo to Charleston, South Carolina, in the United States, is sufficient to make over 110 nuclear weapons. However, the plutonium stockpile remaining in Japan is sufficient for over 1800 nuclear weapons, and the nation`s total plutonium stocks of over 47,000kg– including material stored in France and the UK – is sufficient for over 9400 nuclear weapons.
For more than five decades, Japanese nuclear policy has been based on the production and use of plutonium as a nuclear fuel. However, the failure of both its breeder program and plans to use plutonium as mixed oxide (MOX) fuel in light water reactors, has led to Japan acquiring the largest stockpile of weapons usable plutonium of any non nuclear weapon state. Operation of the 2.1 trillion yen Rokkasho-mura reprocessing plant in Aomori prefecture was recently postponed for the 23rd time. The Japanese government is aiming to pass legislation in the Japanese Diet to try and secure continued financing for Rokkasho from power companies that are facing a deeply uncertain future. Plans to operate Rokkasho from 2018 mean that Japan’s plutonium stocks could rise to as much as 93,000kg of plutonium by 2025.
As a result of reprocessing at the Sellafield nuclear complex in England, including from Japanese reactor spent fuel, over 126 tons of plutonium is stored at the site with no plans for its use. Total global stocks of so-called commercial reactor-grade plutonium was 271 tons at the end of 2014. This amount far exceeds the total amount in all military programs of 140 (+/-10) tons.(2)
“The global reprocessing of spent fuel has created a plutonium nightmare that threatens nuclear weapons proliferation. The UK, France and Japan have led this disastrous program, for which there is no economic rationale,” said Martin Forwood of CORE in the UK. “The clear warning to Japan from here in the UK, which has accumulated over 120 tons of plutonium and with no ability or plans to use it commercially, is, don’t start up the Rokkasho-mura reprocessing plant – it does not solve your nuclear waste problem but makes it far worse and produces vast amounts of weapons material that is only a security and proliferation threat. It’s time to scrap Japan’s plans for further plutonium production,” said Forwood.
Two reactors, Takahama 3 and 4, owned by Kansai Electric, began operation in January and February 2016 loaded with plutonium MOX fuel, with unit 3 operating with 24 assemblies containing 1,088kg of plutonium and unit 4 with 4 assemblies containing 184kg of plutonium. Unit 4 shut down due to an electrical failure three days after start up, while unit 3 was forced to shut down on March 10thfollowing a court order. Both reactors remain shut down and are subject of a court injunction preventing operation issued by the Otsu district court, Shiga prefecture on March 9th. They are expected to be non operational for many months. Of the 26 reactors both approved and still under review by the Nuclear Regulation Authority (NRA), Ikata-3, Genkai-3 and Tomari-3 are all intended to operate with plutonium MOX fuel.
“The United States has helped create the global plutonium crisis by approving Japan’s program over decades. Dumping hundreds of kilograms of plutonium in the United States only creates the illusion that something is being done – in reality it solves nothing. With the nuclear reactor program in Japan in disarray, with no credible program for either restarting most reactors or using large amounts of this plutonium, if ever there was a time to abandon its current doomed nuclear energy policy, it is now. The U.S.-Japan Nuclear Cooperation Agreement, the basis for Japan accumulating vast stocks of weapons material, is up for re-negotiation in 2018 – approval for Japan to continue acquiring plutonium must be terminated,”said Tom Clements of Savannah River Site Watch.
The Department of Energy has no plans for final disposal of the Japanese plutonium, which will be added to the existing stockpile of 13 tons at the Savannah River Site, demonstrating that the shipment is largely a commercial dumping operation to secure funds for the beleaguered weapons material production site near Aiken, South Carolina, as pointed out by Savannah River Site Watch.

Secret Plutonium Shipment Exposes Failure of Non Proliferation and Security Policy in Advance of Nuclear Security Summit and the Threat from Japanese Stockpiling Program
Armed British transport ships expected to arrive Tokai port Sunday
March 18th 2016 Tokyo…A shipment of weapons-grade plutonium scheduled to depart the port of Tokai, Ibaraki prefecture this coming weekend highlights the failure, but also the proliferation risks, of the current Japanese nuclear policy, a coalition of five non-governmental organizations warned today. A cargo of 331kg of plutonium will be loaded on to the Pacific Egret, an armed British nuclear transport ship, prior to departure under armed escort to the United States. It will be the largest shipment of separated plutonium since 1.8 tons of plutonium was delivered to Japan by controversial Akatsuki-maru in 1992. The two month voyage to the Joint Base Charleston-Weapons Station will then see the plutonium dumped at the Department of Energy Savannah River Site (SRS) in South Carolina.(1) The U.S. National Nuclear Security Administration, which is responsible for the shipment, has identified that storage in Japan poses a security risk justifying its removal.(2)
Citizen Nuclear Information Center (Japan); Green Action (Japan); Savannah River Site Watch (U.S.); CORE (England), and Greenpeace, condemn the shipment as a dangerous distraction from the major problem in Japan which is its overall nuclear energy policy, where over 9 tons of plutonium remains stockpiled and there are plans to produce many tons more during the coming decade. The representatives of the five organizations have worked together over the past quarter century against Japan`s plutonium and nuclear fuel cycle program.
Two-hundred and thirty six kilograms of the Tokai plutonium was supplied to Japan from the UK, with 2 kilograms from France and the remainder from the U.S. for neutronic testing purposes at the Japan Atomic Energy Agency Fast Critical Assembly facility at Tokai-mura in Ibaraki. The facility has been used as a basis for Japan`s failed fast breeder reactor program, in particular the MONJU reactor. For more than five decades, Japanese nuclear policy has been based on the production and use of plutonium as a nuclear fuel. However, the failure of both its breeder program and plans to use plutonium as mixed oxide (MOX) fuel in light water reactors, has led to Japan acquiring the largest stockpile of weapons usable plutonium of any non nuclear weapon state.
For the U.S. and Japanese government, the Tokai shipment will be mistakenly hailed as demonstrating their commitment to reducing the threat from fissile materials. Both Prime Minister Abe and President Obama plan to announce the ‘success’ of the removal from Japan, at the fourth Nuclear Security Summit from March 31st-April 1st in Washington, D.C. (3), while Japan will be desperate to avoid any discussion of the proliferation and security threat posed by its plutonium fuel cycle program.
“If 331 kg of plutonium warrants removal from Japan on the grounds of its vulnerability and in the interests of securing nuclear weapons material, then there is no credible justification for Japan’s current program and future plans to increase its plutonium stockpiling. Hailing a shipment of hundreds of kilograms of plutonium as a triumph for nuclear security, while ignoring over 9 tons of the weapons material stockpiled in Japan and in a region of rising tensions, is not just a failure of nuclear non proliferation and security policy but a dangerous delusion,” said Shaun Burnie, senior nuclear specialist at Greenpeace Germany, who is currently in Japan.
In total, Japan`s current stockpile is around 46,700 kg, of which 9,528kg is located in Japan, the remaining balance being stored in France and the UK. The shipment from Tokai port will reduce its stockpile to 9,197 kg. Less than 8kg is sufficient for one nuclear weapon. While the Tokai shipment consists of weapons grade plutonium, and the vast bulk of Japan`s remaining stockpile is designated reactor-grade plutonium, from a security and non proliferation perspective there is no practical distinction and reactor-grade plutonium is capable of being used for the manufacture of nuclear weapons — a point highlighted by Shigeru Ishiba, a former Liberal Democratic Party Defense Minister, when speaking in 2011 described Japan`s nuclear energy program as “a tacit nuclear deterrent”.(4)
Two reactors, Takahama 3 and 4, owned by Kansai Electric, began operation in January and February 2016 loaded with plutonium MOX fuel, with unit 3 operating with 24 assemblies containing 1,088kg of plutonium and unit 4 with 4 assemblies containing 184kg of plutonium. Unit 4 shutdown due to an electrical failure three days after start up, while unit 3 was forced to shutdown on March 10th following a court order. Both reactors remain shutdown and are subject of a court injunction preventing operation issued by the Otsu district court, Shiga prefecture on March 9th. They are expected to be non operational for many months. Of the 26 reactors under review by the Nuclear Regulation Authority (NRA), Ikata-3, Genkai-3 and Tomari-3 are all intended to operate with plutonium MOX fuel.
“On current plans, and if ever the Rokkasho-mura reprocessing plant begins operation, Japan`s program could yield as much as 93,000kg by 2025 – most of which will remain unused. The reactor program in Japan is in crisis with no credible program for either restarting most reactors or using large amounts of this plutonium. If ever there was a time to abandon its current doomed nuclear energy policy, it is now. The Obama administration in its last year has an opportunity to step up and actively reduce the spiraling proliferation dynamic in East Asia – this should be top of the agenda in Washington instead of being ignored. The next step is to challenge the basis of the U.S.-Japan nuclear cooperation agreement which runs to 2018 – approval for Japan to continue acquiring plutonium must be reversed,” said Burnie.
The Department of Energy has no plans for final disposal of the Japanese plutonium, which will be added to the existing stockpile of 13 tons at the SRS, demonstrating that the shipment is largely a commercial dumping operation to secure funds for the beleaguered weapons material production site near Aiken, South Carolina, as pointed out by Savannah River Site Watch.

Lessons of the Fukushima Nuclear Power Plant Have Not Been Learned
We Strongly Oppose the Restart of the Takahama Nuclear Power Plant Unit 3 Located in the Seismically Active Wakasa Bay Region of Japan
29 January 2016
For immediate release. Contact: Aileen Mioko Smith +81-90-3620-9251
There are fifteen nuclear reactors located in the Wakasa Bay region of Fukui prefecture, one of the most seismically active areas among nuclear power plant sites in this earthquakeridden archipelago of Japan.
Takahama Unit 3 is being allowed to restart by Japan’s Nuclear Regulation Authority (NRA) even though it does not meet NRA stardards for evaluating seismic motion, whereby the variations from the average recorded earthquake motions of past earthquakes must be taken into consideration. The plant is not safe from earthquakes.
The NRA also approved the plant’s restart even though Kansai Electric, the owner operator, does not have plans for constructing a seismic isolation building which would act as a control center in the event of a serious accident involving an earthquake. Such a building existed at Fukushima Daiichi and is considered by Tepco to have been the lifeline for not worsening the accident.
Clearly, the lessons of the March 11, 2011’s Fukushima Daiichi accident have not been learned by the regulator and Kansai Electric.
Kenichi Oshima of Ritsumeikan University rightly points out that Kansai Electric will only break even if four reactors at Takahama and Ohi all operate with regularity. Electric prices will only come down if the very old Takahama Units 1 and 2 are allowed to operate. In other words, restarting Takahama Units 3 and 4 will actually only increase electricity rates.
On 21 January, a coalition of NGOs including Green Action met with NRA officials who confirmed that only spot checks had been undertaken to confirm regulatory compliance of Takahama Unit 3 electric cabling. This means the NRA does not know if there is adequate separation between the cables needed for back-up systems and other cables, a vital requirement for meeting the fire code. Only Takahama Units 3 and 4 and the alreadyoperating two Sendai reactors are exempt from undertaking comprehensive examinations of the electric cables. No valid explanation has been given by the NRA on why these four reactors are exempt. Lack of compliance could lead to a catastrophic accident.
Freedom of information disclosure has revealed that MOX (mixed plutonium uranium oxide) fuel to be used at Takahama Unit 3 (and subsequently other nuclear power plants) is of markedly inferior quality compared to uranium fuel normally used in reactors. The NRA has not re-assessed the MOX fuel standards created by the now-defunct NISA (the former regulator) which were created before the Fukushima Daiichi accident. MOX fuel is known to be less safe than uranium fuel. Here again, neiher the NRA nor the utilities have learned the lessons of Fukushima.
Nearly 180,000 people must evacuate from Fukui and Kyoto prefectures in the event of a serious accident at the Takahama plant. Small children near the plant remain unprotected.
Their parents must battle through congested traffic just to get potassium iodine pills. Green Action as part of a coalition of citizens in the Kansai region has made over 60 visits to cities evacuating and others which are evacuation points. We have learned there is no viable evacuation plan in place for the tens of thousands of people with special needs–inpatients and outpatient at hospitals and various facilities, those in day care, and those with handicaps living at home. When others can flee, there are no vehicles to transport these people nor medical care prepared if and when they reach the evacuation facilities. Restart of the Takahama plant is a human rights injustice toward children and those with handicaps.
As for evacuation drills, Kansai Electric confirmed back in 2014 that Fukui Prefecture asked for the accident scenario to be sent from the utility to be for a small enough accident so the prefecture’s evacuation drills could cope. All drills in the Fukui and northern Kyoto Prefecture region have been grossly inadequate. There is no consideration that there could be heavy snow or an earthquake.
The government and Kansai Electric has ignored repeated calls by the 8 prefectures and 4 cities of the Union of Kansai Governments which state since they are in the region that can be affected by a serious accident, therefore they should have consent rights when it comes to reactor restart issues.
“Restart of Takahama violates the NRA seismic safety standard. Operating a Japanese reactor without a seismic isolation emergency control room is negligence in the extreme. Tens of thousands of children including babies and those with special needs not being protected under current emergency management planning is an outright human rights violation.” said Aileen Mioko Smith, executive director of Green Action based in Kyoto.

Japan’s Nuclear Regulator:
We don’t know if Takahama Reactor has significant fire safety violation
Reactor due to start January 29th
January 26, 2016, Tokyo –Greenpeace and Green Action today condemned the failure of the NRA to verify that critically important electric cabling inside the Takahama reactors meet the agency’s own fire safety regulations. At a meeting held in the National Diet on January 21st, representatives of the NRA admitted under questioning from citizens and NGOs, that they simply do not know whether Takahama 3&4 reactors are in violation.(1)
Kansai Electric plans to restart Takahama 3, located on Wakasa Bay in Fukui prefecture, on January 29th.
The safety-related cabling in a reactor must be separated to ensure that in the event of fire or other singular incident, critical redundant safety systems and power supplies are not lost. If the cabling is not adequately separated – by physical distance, cabling trays, and fire barriers in accordance with regulations– this would pose a significant risk to reactor safety – including the risk of a losing cooling systems which, in worst case, could lead to a core meltdown.
The NRA has ordered all nuclear plant operators in Japan to provide reports on the status of cable separation at their reactors before the end of March – except for Takahama and Sendai.(2)
“This latest example of complete negligence by the NRA just days before the Takahama unit 3 reactor is scheduled to restart is wholly unacceptable. It’s like allowing an airliner packed with passengers to take off without knowing whether the fuel lines and the control wires are crossed. If an accident happens, the power and backup safety systems could be taken out at once, and the plane is going down. While the NRA may be content to allow the Takahama safety cables to remain in the black box, the public deserves to know what’s inside before their lives and livelihoods are put at significant risk,” said Kendra Ulrich, Senior Global Energy Campaigner, Greenpeace Japan.
In March 2015, the Nuclear Regulatory Agency provided an assurance of safety to the Union of Kansai Governments for the Takahama reactors. It told the Union that the NRA had confirmed that the utility’s policy for the reactors would ensure compliance with nuclear safety regulations. This includes the issue of electric safety cabling.(5) The Union, made up of eight prefectural governments and four cities, has challenged the restart process for the Takahama reactors; it represents 22 million people living in the greater Kansai region. They provided the same assurance to local governments in the Union, as well as Fukui prefecture.
“The fact the Japanese government, in its efforts to neutralise the mounting opposition to restart from the Union Kansai Governments, told them last March that the plant complied with their regulations shows both the level of incompetence and deception at the heart of Japan’s nuclear industry,” said Aileen Mioko Smith, Director, Green Action, Kyoto. “The NRA are clearly not being honest or transparent about what they know about this issue. When completing their overall assessment of the safety design of the Takahama reactors in August last year, did they not verify compliance with their regulations during this process? If not, why not?” said Smith.

1 – A coalition of NGO’s have petitioned the NRA on a ranges of safety issues at Takahama, including safety cabling. There are 14 petitioners including: Green Action, Friends of the Earth, Greenpeace Japan, and numerous local NGOs.
2 – The NRA admitted in December that it knew of at least six nuclear plants in Japan had a safety cable problems that meant they were in non compliance with their regulations – all seven reactors at Kashiwazaki-Kariwa; units 3 and 4 at Fukushima Daiini; unit 4 at Hamaoka, and Shika unit 1, Onagawa unit 3 and Higashi-dori unit 1 – for a total of 13 reactors.
