NUCLEAR REGULATORY COMMISSION
[NRC-2009-0568]
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
Comment.''
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.

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.

Chief, Fire Research Branch, Division of Risk Analysis, Office of
