We are sure it's just an oversight, but given Abe's increasingly nationalist banter (and an economy set to plunge in Q2 after Q1's pre-tax-hike surge), it is certainly worth noting that, as The Japan Times reports, Japan failed to include 640 kg of unused plutonium in its annual reports to the International Atomic Energy Agency in 2012 and 2013, in what experts are terming an "inappropriate omission." The unreported amount is enough to make about 80 nuclear bombs. reassuringly, officials noted "there is no problem in terms of security against nuclear terrorism," but as another pointed out, "should make efforts to improve" its reporting. Well, yeah, especially given that Japan possesses the largest amount of plutonium among nonnuclear weaponized nations.
Japan failed to include 640 kg of unused plutonium in its annual reports to the International Atomic Energy Agency in 2012 and 2013, in what experts are terming an “inappropriate omission.”
The stock is part of mixed plutonium-uranium oxide (MOX) fuel stored in a reactor that was offline during this period, and was thus deemed exempt from IAEA reporting requirements, said an official at the Japan Atomic Energy Commission.
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.
But don't worry, because...
The official said, “There is also no problem in terms of security against nuclear terrorism.”
It seems the IAEA is a little concerned.
“From the safeguards point of view, this material is still unirradiated fresh MOX fuel regardless of its location,” former IAEA Deputy Director General Olli Heinonen said. “If it has indeed not been irradiated, this should be reflected in the statements.”
In March 2011, the MOX fuel was loaded into the No. 3 reactor of Kyushu Electric Power Co.’s Genkai nuclear plant in Saga Prefecture during a regular checkup. It was removed two years later because the reactor has remained idled since the Fukushima nuclear crisis.
When Japan reported to the IAEA in 2012 that it had 1.6 tons of unused plutonium at reactors nationwide as of the end of 2011, down from 2.2 tons the previous year, it excluded the 640 kg. The amount reported a year later remained at 1.6 tons.
The fuel has been kept unused in a fuel pool since March 2013.
IAEA maybe, but nobody else has a reason to be worried.
Japan is subject to rigorous international monitoring, as it possesses the largest amount of plutonium among nonnuclear weaponized nations, with more than 44 tons extracted from spent fuel and reprocessed for reuse under its nuclear fuel cycle policy.
