A joint workshop of the Working Group on the Analysis and Management of Accidents (WGAMA) and the Working Group on Risk Assessment (WGRISK) on implementation of severe accident management (SAM) measures was sponsored by the Committee on the Safety of Nuclear Installations (CSNI) of the OECD Nuclear Energy Agency (NEA) and was held in Schloss Böttstein, Switzerland on 26-28 October 2009, in co-operation with the Paul Scherrer Institute (PSI) and the Swiss utilities running NPPs Beznau, Leibstadt, Gösgen and Mühleberg.
This workshop is a follow-up to the past CSNI activities in the area of SAM implementation, and takes stock of the progress made since previous workshops. In particular, the present workshop represents an update of the status of SAM measures and their implications since the OECD/CSNI workshop held in 2001 at PSI Switzerland. Since the 2001 workshop, additional work has been performed to integrate emergency procedures and SAM measures into risk assessments in order to better reflect operator responses to recover the plant from a damaged state. Therefore, a major focus of the workshop was to address SAM measures for both operating plants and new plant designs (as available) and the integration of SAM measures into contemporary/future probabilistic risk assessments.
