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.
