Japan fails to include 640 kg of unused plutonium in report to IAEA
TOKYO. KAZINFORM Japan has failed to include 640 kilograms of unused plutonium in its annual report to the International Atomic Energy Agency in 2012 and 2013 in what experts say is an inappropriate omission.

The plutonium concerned is part of the plutonium-uranium mixed oxide fuel placed at the time in an offline reactor and is considered as being used and hence exempt from reporting to the IAEA, said an official at the governmental Japan Atomic Energy Commission. But experts warn that Japan's reporting does not reflect the actual state of unused plutonium that could be diverted for nuclear weapons. The unreported amount is enough to make about 80 nuclear bombs, Kyodo reports.
