Japan’s nuclear cooperation agreement with the U.S. — the pillar of Tokyo’s nuclear energy policy — renewed automatically on July 15, 2018 after the current pact, which took effect in 1988, expire The agreement allows Japan to be the sole non-nuclear-weapons state to use plutonium for peaceful purposes and underlies the country’s policy of recycling spent nuclear fuel.
But the renewal comes at a time when Japan’s “plutonium exception” is increasingly under scrutiny…Japan’s neighbors have cried foul over Japan’s plutonium exception. China has said it creates a path for Japan to obtain nuclear weapons. South Korea, which also has a nuclear cooperation agreement with the U.S., has pressed Washington hard to be granted similar freedom on fuel reprocessing. Countries such as Saudi Arabia that are looking to develop their own nuclear programs have also protested….Resolving the inconsistent treatment afforded Japan’s plutonium stockpile would make it easier for the United States to convince Pyongyang to give up reprocessing capabilities as part of its denuclearization. On July 3, 2018, Japan’s cabinet approved a new basic energy plan that includes reducing plutonium holdings, aiming to assuage American concerns…
So far, the U.S. has not called on Japan to abandon its plutonium entirely, or to speed up its reduction. And there is little chance the U.S. will end the cooperation agreement, as “Japan’s nuclear technology is indispensable to the American nuclear industry,” according to a Japanese government source.
