Nuclear loss

The UK Atomic Energy Authority has ruled out any breach of security
at its Dounreay nuclear site, where the hunt is still on for 10 kilograms
of ‘missing’ enriched uranium. A spokesman said that the authority is close
to working out why the uranium seems to have ‘disappeared’. A second stocktake
of the authority’s fissionable material is likely to reveal that the error
was a book-keeping mistake.
