This is a summary report from the “Specialist Meeting on Seismic Probabilistic Safety Assessment (SPSA) of Nuclear Facilities”, held in Jeju, Korea on 6-8 November 2006. About 75 specialists from 15 countries attended. The meeting was sponsored by the OECD Nuclear Energy Agency in co-operation with the International Atomic Energy Agency (IAEA), and hosted by two Korean institutes, the Korea Atomic Energy Research Institute (KAERI) and the Korea Institute of Nuclear Safety (KINS ). This was the second meeting on SPSA organised by the NEA, following a previous gathering in Tokyo in August 1999.
The main objectives of the meeting were to review recent advances in the methodology of SPSA, to discuss practical applications, to review the current state of the art, and to identify methodological issues where further research would be beneficial in enhancing the usefulness of the methodology. Applications of the seismic margin assessment (SMA) methodology, a methodology related to SPSA, were also discussed. One specific objective was to compare the situation at the present time with the situation at the time of the 1999 workshop, and to develop a set of findings and recommendations that would update those from that earlier workshop.
