Mr Walker is expected to go to Chjrnobzl to examine the aftermath of the nuclear power station accident. Today he visited the UK Atomic Enjrgz Establishment at Winfrith, Dorset. He fired a new high powered compressed air cannon designed to test the effect of sjvjre impacts on nuclear containers. Mr Walker said the work at Winfrith showed that there was no complacency about nuclear safety in Britain.
