Procedures for Conducting Probabilistic Safety Assessments of Nuclear Power Plants (Level 1)

IAEA Safety Series No. 50-P-4
English STI/PUB/888 92-0-102392-8
175 39.00 1992


This safety practice report provides guidance on conducting a Level 1 PSA for internal events in nuclear power plants. The main emphasis is on the procedural steps of the PSA rather than the details of the corresponding methods. The report is intended to assist technical persons managing or performing PSAs. A particular aim is to promote a standardized framework, terminology and form of documentation for PSAs so as to facilitate external review of the results. The report not only describes methods, but also considers advantages and limitations of various approaches and indicates those most widely used to date.
