Abstract
This press statement by the Health and Safety Executive covers nuclear incidents in the United Kingdom in the period 1st January to 31st March 1993. Of the six incidents reported, four occurred at the Windscale and Calder Works of British Nuclear Fuels (BNFL, Sellafield). Two of these were classified as level 2 on the International Nuclear Event Scale. They were a leakage of plutonium-bearing solvent liquor onto the plant floor which did not involve contamination of personnel nor release of airbourne radioactivity, and a contamination wound received by a Quality Assurance Inspector inspecting a weld on a plutonium nitrate transfer line. The other two Sellafield incidents involved short term increases in radioactive discharges from stacks; in both cases no on-site personnel were affected and the maximum potential dose to the general public was assessed at less than 0.02% of the annual permitted dose. During the transfer of stocks of protactinium 231 between two laboratories in the same building at AEA Technology Harwell, alpha contamination of the floor of one of the laboratories was detected and staff received minor skin doses well below defined dose limits; there was no release of radioactivity to the environment. At Dungeness B power station, an
