Human Reliability Analysis in Probabilistic Safety Assessment for Nuclear Power Plants

This document presents a practical approach for incorporating human reliability analysis (HRA) into probabilistic safety assessment (PSA). It describes the steps needed and the documentation that should be provided both to support the PSA itself and to ensure effective communication of important information arising from the studies. It also describes a framework for analysing those human actions which could affect safety and for relating such human influences to specific parts of a PSA.
