Abstract

Issues with past practice in seismic hazard analysis of nuclear power plant sites in Korea are addressed. Brief review on both deterministic and probabilistic methods in seismic hazard analysis is given, and most of the continuing discussion is focussed on the probabilistic seismic hazard analysis. Causes of uncertainty are traced on the basis of the cases that the assessment methodology was applied to the nuclear power plant sites. Considerations on the assessment include the role of experts, a representative seismic catalog, seismic source zonation, earthquake ground-motion relationship, and evaluation process. Factors increasing uncertainty in each item are analyzed and some feasible solutions are discussed.

국내 원전부지 지진재해도 평가 경험을 바탕으로 향후 지진재해도 평가 시 보다 정량적인 평가를 위하여 고려하여야 할 사항에 대하여 점검하였다. 지진재해도 평가 방법을 양분하는 것으로 알려진 결정론적 방법과 확률론적 방법에 대하여 간단히 소개하였으며, 대부분의 후속 논의는 확률론적 지진재해도 평가에 집중하였다. 이 평가를 국내 원전부지에 적용한 과거 사례를 토대로 제기된 불확실성의 원인을 추적하였다. 확률론적 지진재해도 평가의 고려사항으로 전문가의 역할, 대표지진목록 작성, 지진원 설정, 지진-지반운동 관계식 개발 및 지진재해도 평가 절차에 대하여 토의하였다. 각 주제별로 불확실성을 증가시키는 요인을 분석하고 국내 환경에 적합한 해결 방안을 토의하였다.
