Abstract

In this paper many vulnerable areas of the present fire PSA methodology were revealed to apply risk-informed fire protection to nuclear power plants. The results and insights from the fro PSA should be used as a part of a risk-informed decision making process rather than the complete technical basis for decision making. The degree of support and scope of applications is dependent on the accuracy and validity of the model used in the fire PSA. Accordingly; the usefulness of the fire PSA will increase as ongoing research and development efforts lead to improvements in the state of the art technology and as improvements in the implementation of the state of the art technology lead to more consistent results.

본 논문에서는 현재 세계적으로 사용되고 있는 화재 PSA 방법론을 살펴보고 화재방호를 목적으로 위험도 정보를 이용할 시 요구되는 방법론의 개선 사항을 파악하였다. 화재 PSA의 결과 및 이를 통한 통찰(insight)은 의사 결정을 하는데 완전한 기술적인 근거라 하기보다는 위험도 정보를 활용한 의사 결정 과정의 일부로서 사용될 수 있으며, 화재 PSA 결과의 적용 분야와 적용 수준은 PSA에서 사용된 모델의 정확성과 타당성에 좌우된다고 할 수 있다. 따라서 화재 PSA의 유용성은 많은 분야의 연구와 개발을 통해 현재 기술 수준 증진에 따라 확대될 것이며, 그에 따라 더 일관성 있는 결과를 낳게 될 것으로 판단한다.
