Hickman, J W

This procedures guide describes methods for performing probabilistic risk assessments (PRAs) for nuclear power plants at four levels of scope: (1) systems analysis; (2) systems and containment analysis; (3) systems, containment, and consequence analysis; and (4) full risk assessment, including external events. After reviewing its objectives and limitations, this document describes the organization and management of a PRA project and then presents procedures for accident-sequence definition and systems modeling, human reliability analysis, the development of a data base, and the quantification of accident sequences. Procedures for evaluating the physical processes of core meltdown are presented next, followed by guidance on the evaluation of radionuclide releases from the containment as well as the analysis of environmental transport and offsite consequences. The analysis of external hazards is discussed next, including procedures for seismic, fire, and flood analyses. The guide concludes with suggestions for the development and interpretation of results and the performance of uncertainty analyses.
