Applications of Foreign Probabilistic Safety Assessment Experience to the U.S. Nuclear Regulatory Process.

摘要

This report is a summary of applications of probabilistic safety assessment (PSA) in the United States and foreign countries. It is intended to stimulate discussion on the applicability of foreign experience to the United States, provide information on foreign safety technology development and focus the United States goals for future participation in the activities of the Committee for the Safety of Nuclear Installations (CSNI), Principle Working Group 5 (PWG5). Results indicate that the United States leads the surveyed countries in the completion and application of comprehensive PSAs of public safety impacts from nuclear power plants. European experience has focused on the use of reliability analyses in support of design and operational decisions. It is recommended that use of probabilistic analyses be expanded in the United States for engineering applications based on the success in European countries.
