In 1998, the Committee on Nuclear Regulatory Activities (CNRA) issued a report on Future Nuclear Regulatory Challenges. This report discussed the potential erosion of safety margins as an area for further research. To address this problem, the CSNI approved in December 2003 the Safety Margins Action Plan (SMAP) and established an international working group aimed at developing a framework for integrated assessments of the changes to the overall safety of the plant as a result of simultaneous changes in plant operation/conditions. This final report is the result of the SMAP Task Group work as detailed in several technical notes issued during the three-year activity period.
