Plutonium cell reduced to rubble

A stump of concrete and steel is all that remains standing of one Britain’s most historic nuclear research facilities from the 1950s.

Demolition contractor John Gunn is in the final stages of clearing away the reinforced shield that once surrounded the plutonium criticality cell pressure vessel.

It is the fourth and final cell to be demolished from the era of criticality research at Dounreay in the 1950s and 1960s.
