This PRA Review Manual describes the approach for reviewing a Level 1 PRA, i.e., one which carries the accident analysis to the point of determination of core damage frequency, but excludes questions of containment integrity and of offsite consequences. The manual will be revised as comments are received, and as experience is gained from its use. The procedure involves three parts: the first (Phase 1) is concerned with the formal aspects of the PRA such as its apparent completeness, scrutability, and determines to what extent the PRA can usefully be further examined; the second part (Phase 2) reviews the analyses in a comprehensive and thorough but qualitative way, which is designed to focus on unusual or unsupported features, and to lay the groundwork for further, more detailed studies; and the final stage (Phase 3) addresses details of issues and concerns raised in the earlier phases, and involves detailed quantitative examination of selected areas to ensure the overall validity.
