Abstract
Apparatus is disclosed for decontaminating a nuclear reactor pressure vessel. It comprises a buoyant annular frame which descends into the vessel as the water level within it is lowered. Spray nozzles move around the frame on trolleys in a reciprocating fashion and spray water under high pressure on the inner surface of the vessel wall, resulting in automatic washdown of the reactor vessel.
