Britain has plutonium for 17,000 Nagasaki bombs

LONDON, Sept 21(Reuters): Britain has amassed a stockpile of more than 100 tonnes of plutonium -- enough for 17,000 bombs of the size that flattened Japan's Nagasaki in 1945, a report from the country's top science institution said on Friday.

The toxic stockpile, which has doubled in the last decade, comes mainly from reprocessing of spent uranium fuel from the country's nuclear power plants, so to stop it growing the practice must end, the Royal Society said.
