Secret Plutonium Fuel Shipment Planned for Japan’s Takahama Reactors

Tokyo, 6 June 2017 – With today’s restart of the Takahama 3 reactor in Fukui Prefecture, Greenpeace revealed that the nuclear operator Kansai Electric and the French nuclear company AREVA are planning a secret plutonium fuel shipment from France to the Takahama plant. Plutonium fuel (MOX) reduces the safety of the reactor, increasing both the risk of a severe accident and its radiological consequences. The shipment is scheduled to depart Cherbourg France on 7 July.

This also presents serious security issues, both as it is a potential terrorist target and that the plutonium in the MOX fuel is direct use nuclear weapons material. Due to these risks, the U.S. State Department and other agencies are required to approve the security plan for plutonium shipments to Japan under the terms of the US – Japan Peaceful Nuclear Cooperation Agreement of 1988. The Trump administration has approved this shipment, despite the increasingly unstable conditions in the region.

The last thing Northeast Asia needs at this time, or at any time, is more nuclear weapons-usable material. Last year, the U.S. removed 331 kilograms of  plutonium from Japan due to security risks, while ignoring the 10 tons of material that remained. One year later, at least 500 kg more plutonium is being approved for delivery to Japan. Plutonium is not your normal cargo to be traded as a commodity. It can be used as nuclear bomb material. Japan’s bankrupt plutonium program, and its endorsement by the Trump administration, is a further threat to the peace and security of this troubled region,” said Shaun Burnie, nuclear specialist at Greenpeace Germany in Tokyo.

The shipment comes at a time when Northeast Asia is already destabilized due to threats on the Korean peninsula, the spectre of military conflict, and the increasing risks of nuclear weapons proliferation. Japan’s decades long and multibillion dollar plutonium program has failed to ensure energy security for Japan, but it has led to the nation accumulating over 48 tons of plutonium, 10 of which is stored in Japan, and the rest in the UK and France.

This shipment will consist of at least 16 plutonium fuel (MOX) assemblies, which are planned to be loaded into the Takahama 4 reactor during its next refueling, expected in 2018. The amount of plutonium in the shipment due to leave France next month is estimated to range from between 496-736kg – as little as 5kg is sufficient for one nuclear weapon.

Two lightly armed British vessels, the Pacific Egret and Pacific Heron, are scheduled to leave the French port of Cherbourg on 7th of July, and are expected to arrive in Takahama between mid-August and early September, depending on the route chosen. One of the ships will transport the plutonium fuel, and the other will act as ‘armed escort’.

Both Takahama 3 and 4 already have plutonium MOX fuel in their cores, with 24 and 4 MOX assemblies loaded into each reactor respectively.

KEPCO’s unjustified restart of the Takahama 3 reactor is made worse by the fact that they are planning a secret plutonium shipment which will increase the amount of dangerous plutonium MOX in their reactors. The Takahama reactors already pose an unacceptable threat to the people of Fukui and Kansai region. This will be compounded by the even greater usage of plutonium MOX fuel,” said Shaun Burnie, Senior Nuclear Specialist with Greenpeace Germany (currently based in Japan).

Due to the severity of the impacts of a nuclear disaster involving MOX fuel, citizens groups, including Greenpeace, have demanded that AREVA release vital safety data on the MOX fuel produced for Japan, including for the Fukushima Daiichi 3 reactor and the Takahama reactors, due to evidence of flawed production and quality control during manufacture.(1) To date, AREVA has failed to release any of the safety data. AREVA also refused to release the same data for MOX fuel loaded into the Fukushima Daiichi reactor 3 in 2000. The AREVA company which has suffered a near meltdown of its business in recent years, is desperate to secure more MOX fuel contracts with Japan, which suffered as a direct consequence of the 2011 Fukushima Daiichi accident leading to the shutdown of the Japanese reactor fleet.

Of the five reactors now operating in Japan, three are operating with varying amounts of plutonium MOX fuel. There is a possibility of additional MOX fuel being in the shipment for other Japanese reactors – Ikata 3 is operating with MOX fuel, and the Genkai 3&4 will operate with MOX fuel if they restart before March 2018.
