NUREG-1934, Nuclear Power Plant Fire Modeling Application Guide 
(NPP FIRE MAG), Draft Report for Comment

AGENCY: Nuclear Regulatory Commission.

ACTION: Announcement of issuance for public comment, availability.


SUMMARY: The Nuclear Regulatory Commission has issued for public 
comment a document entitled: ``NUREG-1934 (EPRI 1019195), Nuclear Power 
Plant Fire Modeling Application Guide (NPP FIRE MAG), Draft Report for 

DATES: Please submit comments by March 10, 2010. Comments received 
after this date will be considered if it is practical to do so, but the 
NRC staff is able to ensure consideration only for comments received on 
or before this date.

ADDRESSES: You may submit comments by any one of the following methods. 
Please include Docket ID NRC-2009-0568 in the subject line of your 
comments. Comments submitted in writing or in electronic form will be 
posted on the NRC Web site and on the Federal rulemaking Web site 
Regulations.gov. Because your comments will not be edited to remove any 
identifying or contact information, the NRC cautions you against 
including any information in your submission that you do not want to be 
publicly disclosed.
    The NRC requests that any party soliciting or aggregating comments 
received from other persons for submission to the NRC inform those 
persons that the NRC will not edit their comments to remove any 
identifying or contact information, and therefore, they should not 
include any information in their comments that they do not want 
publicly disclosed.
    Federal Rulemaking Web site: Go to http://www.regulations.gov and 
search for documents filed under Docket ID NRC-2009-0568. Address 
questions about NRC dockets to Carol Gallagher 301-492-3668; e-mail

SUPPLEMENTARY INFORMATION: There is a movement to introduce risk-
informed and performance-based (RI/PB) analyses into fire protection 
engineering practice. This movement exists in both the general fire 
protection and the nuclear power plant (NPP) fire protection 
communities. The U.S. Nuclear Regulatory Commission (NRC) has used 
risk-informed insights as a part of its regulatory decision making 
since the 1990s. In 2002, the National Fire Protection Association 
developed NFPA 805, Performance-Based Standard for Fire Protection for 
Light-Water Reactor Electric Generating Plants. In July 2004, the NRC 
amended its fire protection requirements in Title 10, Section 50.48, of 
the Code of Federal Regulations to permit existing reactor licensees to 
voluntarily adopt fire protection requirements contained in NFPA 805 as 
an alternative to the existing deterministic requirements. NUREG-1934 
(EPRI 1019195), ``Nuclear Power Plant Fire Modeling Application Guide, 
Draft Report for Comment'' was written as a collaborative effort by the 
U.S. Nuclear Regulatory Commission (NRC) Office of Nuclear Regulatory 
Research (RES), the Electric Power Research Institute (EPRI), and the 
National Institute of Standards and Technology (NIST) to provide 
guidance on using fire modeling for nuclear power plant applications. 
The features and limitations of the five fire models documented in 
NUREG-1824 (EPRI 1011999), Verification & Validation of Selected Fire 
Models for Nuclear Power Plant Applications are discussed relative to 
NPP applications. Finally, the report describes the implications of the 
of verified and validated (V&V) fire models that can reliably predict 
the consequences of fires.

    Dated at Rockville, Maryland, this 17 day of December, 2009.

    For the Nuclear Regulatory Commission.
