Japan on Tuesday admitted that 206kg of its plutonium - enough to make about 25 nuclear bombs - is unaccounted for.
Government scientists said that 6,890kg of plutonium had been extracted since 1977 from spent nuclear fuel at a processing plant about 120km north east of Tokyo. But that is 3 per cent short of the amount the plant was estimated to have produced.
About 5kg to 8kg of plutonium are needed to make a 20-kiloton atomic bomb similar to the one that destroyed Nagasaki in 1945.
Experts said the missing amount was surprisingly large.
