SUPPLEMENTARY NOTESNRC Project Manager, J.S. Hyslop11. ABSTRACT (200 words or less)EPRI Project Manager, Robert P. KassawaraThis report documents state-of-art methods, tools, and data for the conduct of a fire Probabilistic Risk Assessment (PRA) for acommercial nuclear power (NPP) application. This report is intended to serve the needs of a fire risk analysis team byproviding a structured framework for conduct of the overall analysis, as well as specific practices to address each key aspect ofthe analysis. The methods have been developed under the Fire Risk Requantification Study. This study was conducted as ajoint activity between the Electric Power Research Institute (EPRI) and the U.S. Nuclear Regulatory Commission (NRC) Officeof Nuclear Regulatory Research (RES) under the terms of an NRC/EPRI Memorandum of Understanding on CooperativeNuclear Safety Research and an accompanying Fire Risk Addendum. Participants from the U.S. nuclear power industrysupported demonstration analyses and provided peer review of this methodology. Methodological issues raised in past fire riskanalyses, including the Individual Plant Examination of External Events (IPEEE) fire analyses, have been addressed to theextent allowed by the current state-of-art and the overall project scope. While the primary objective of the project was toconsolidate existing state-of-art methods, the newly documented methods represent a significant advancement over previouslydocumented methods in many areas.12.
