Study on the Transient Event Experiences for Nuclear Power Plants in Korea

It is recognized that operating experience data is essential for an accident analysis (including Probabilistic Safety Assessment) and other quantitative activities such as a Risk or Performance informed application for a nuclear power plant. The data for a PSA or other quantitative activities have to use specific data with respected to the domestic operation characteristic, because they are considered important contributors to the total risk at a nuclear power plant. The main purpose of this study is to develop transient initiating event frequencies from Korean domestic operational data to utilize them in a PSA or Risk(or performance) informed application. For the objectives, Korean specific nuclear power plants transient data gathering and the development of an analysis program are performed to identify and analysis the data sources and summarize the information they contain in ways useful for a probabilistic safety assessment and other quantitative activities
