Common Basis for Judging the Safety of Nuclear Power Plants Built to Earlier Standards

This report was prepared in response to the recommendation of the IAEA General Conference in 1992 that the Director General develop a process to provide a common basis on which the acceptable level of safety of all operating nuclear power plants built to earlier standards can be judged. This followed a recommendation made at the IAEA Conference on 'The Safety of Nuclear Power: Strategy for the Future' held in September 1991. The report also provides a basis for allocating responsibilities for, and deciding on the best approach to, making a safety assessment, and for selecting criteria to adopt in deciding on what corrective action to take.
