Start Preamble

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.

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 Carol.Gallagher@nrc.gov.

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.
