As a follow-up to the 1995 Special Issues meeting on Regulatory Approaches to PSA, CNRA agreed to discuss Review Procedures and Criteria for Different Regulatory Applications of PSA in 1997. This report summarises Member countries responses to the questionnaire and the subsequent CNRA discussions on this issue. Three main topics are looked at: integration of PSA into the regulatory decision process; technical requirements of PSA with respect to using PSAs to support regulatory decision making; and methods of review for PSAs that will be used to support regulatory decisions. The report summarises experiences of respondents and provides general conclusions that have emerged as well as significant differences in approaches.
