Japan’s massive, and growing, plutonium problem

Japan currently possesses 44 tons of plutonium, according to the Atomic Energy Commission. Nine tons, including the latest shipment, are in Japan, while the remaining tons are in Britain and France, where spent fuel from Japan has been reprocessed.
Storage pools for spent fuel are quickly reaching capacity at nuclear power plants across the nation. If Aomori Prefecture refuses to accept spent fuel, nuclear plants will be saddled with overflowing spent fuel pools and will be unable to continue operations.
Direct disposal, or burying spent fuel without reprocessing, was considered under the previous Democratic Party of Japan government. But discussions have gone nowhere after the Liberal Democratic Party took over government in December.

However, the fuel recycling program has been plagued by so many problems that the nation’s plutonium stockpile could increase further, heightening concerns in the international community about possible nuclear weapons proliferation. Read more »
