SUPPLEMENTARY INFORMATION:

Draft NUREG/CR-6850, “EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities”

The purpose of EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities Draft Report for Comment (NUREG/CR-6850) is to provide state-of-the-art methods, tools, and data for the conduct of fire Probabilistic Risk Assessment (PRA). This methodology was developed under the program, the Fire Risk Requantification Study, which was conducted as a joint activity between EPRI and RES under the terms of an EPRI/RES Memorandum of Understanding on Cooperative Nuclear Safety Research and accompanying Fire Risk Addendum. Licensee applications and U.S. NRC review guidance with respect to many regulatory activities such as the risk-informed, performance-based fire protection rule (endorsing NFPA 805) will benefit for more robust methods. This research addresses the full breadth of FRA technical issues for power operations, and includes consideration of large early release frequency. The current scope excludes low power/shutdown operations, spent fuel pool accidents, sabotage, and PRA level 3 estimates of consequence. While the primary objective of the project was to consolidate existing research from EPRI and NRC in state-of-the-art methods, the newly documented methods represent a significant advancement in many areas over previously documented methods.

The NRC is seeking public comment in order to receive feedback from the widest range of interested parties and to ensure that all information relevant to developing this document is available to the NRC staff. This document is issued for comment only and is not intended for interim use. The NRC will review public comments received on the document, incorporate suggested changes as necessary, and issue the final NUREG/CR-6850 for use.
