Japan Sticks to Nuclear Fuel Recycling Plan Despite Plutonium Stockpile

Japan now has 45.5 tons of separated plutonium, enough to make about 6,000 atomic bombs.  https://thediplomat.com/2020/10/japan-sticks-to-nuclear-fuel-recycling-plan-despite-plutonium-stockpile/

By Mari Yamaguchi, October 21, 2020   Japan’s government said Wednesday it will pursue a nuclear fuel recycling program that would involve extracting plutonium from spent fuel, despite international concerns about the country’s already huge plutonium stockpile and lack of prospects for effectively consuming it as nuclear fuel.

Chief Cabinet Secretary Kato Katsunobu, at a meeting with the governor of Aomori prefecture, home to Japan’s pending nuclear fuel reprocessing plant, reaffirmed that new Prime Minister Suga Yoshihide’s government will pursue the country’s nuclear energy policy.

“The government will firmly promote our nuclear energy policy and fuel cycle programs,” Kato said. He said Japan will make effort to reduce volume and toxicity of high-level nuclear waste, and extract plutonium from spent fuel from a resource conservation point of view.

critics say continuation of spent fuel reprocessing only adds to Japan’s already large plutonium stockpile. Japan also lacks a final repository for high-level nuclear waste.

Wednesday’s meeting came after the Nuclear Regulation Authority granted a safety approval this past summer for the Rokkasho fuel reprocessing plant, operated by Japan Nuclear Fuel Ltd., located in northern Japan, for a planned launch in 2022. The authority also gave a preliminary permit for the Rokkasho MOX fuel production plant, also planned for completion in 2022.

Japan now has 45.5 tons of separated plutonium — 8.9 tons at home, and 36.6 tons in Britain and France, where spent fuel from Japanese nuclear plants has been reprocessed and stored because Japan lacks a plant to produce MOX fuel containing plutonium at home. The amount is enough to make about 6,000 atomic bombs.

Despite security concerns raised by Washington and others, the stockpile is hardly decreasing due to difficulties in achieving a full nuclear fuel recycling program and slow restarts of reactors amid setbacks from the 2011 Fukushima disaster.

Japan reprocesses spent fuel, instead of disposing it as waste, to extract plutonium and uranium to make MOX fuel for reuse, while the U.S. discontinued the costly and challenging program. Allowed under international safeguard rules, Japan is the only non-nuclear weapons state that separates plutonium for peaceful purposes, though the same technology can make atomic bombs.
