Trends in Development of Probability Assessment of Nuclear Power Plant Safety.

摘要

A complete study of probability safety assessment (PSA) of nuclear power plants is a multidisciplinary endeavor, requiring a qualified decision-making team composed of experienced professionals in individual disciplines and requiring good coordination of effort. The main concerns for the execution of a PSA study and related tasks are schematically presented. Also shown is a summary of the main steps for a PSA study at all three levels, with the incorporation of analysis of external events and the reliability of humans, including the necessary uncertainty analyses. 1 ref., 2 figs., 3 tabs.
