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.

    Dated at Rockville, MD, this 8th day of October 2004.

    For the Nuclear Regulatory Commission.
Mark A. Cunningham,
Acting Deputy Director, Division of Risk Analysis and Applications, 
Office of Nuclear Regulatory Research.
