Qualitative PRA insights for use in the design process for ALWRs

A method has been developed for identifying and classifying qualitative design insights from probabilisitc risk assessments and related studies that should be considered in the design of advanced light water reactors. These qualitative design insights may be used in the preliminary design stage when the lack of design detail makes it difficult to perform quantitative risk analysis. These insights are easily accessible thorugh use of a microcomputer-based data base system and may be used to provide designers with risk-related ''lessons learned'' from existing plant system designs.
