ment that the models and methods used in performance-based analyses are used within their limitations and with the rigor required by the nature and scope of the analyses. These analyses may use simple hand calculations or more 9.5.1.1-25 Revision 0 – February 2009 complex computer models, depending on the specific conditions of the scenario being evaluated. The NRC=s Office of Nuclear Regulatory Research and the Electric Power Research Institute have documented the verification and validation (V&V) for parts of five fire models in draft NUREG-1824/EPRI 1011999, AVerification and Validation of Selected Fire Models for Nuclear Power Plant Applications.@ The specific fire models documented are (1) NUREG-1805, AFire Dynamics Tools (FDTs),@ (2) Fire-Induced Vulnerability Evaluation, Revision 1, (3) the National Institute of Standards and Technology Consolidated Model of Fire Growth and Smoke Transport, (4) the Electricité de France MAGIC code, and (5) the NIST Fire Dynamics Simulator. Licensees may propose the use of fire models that have not been specifically V&V=d by the NRC; however, licensees are responsible for providing acceptable V&V of these fire models. The V&V documents for licensee-proposed fire models are subject to NRC review and approval. 9.5.1.1-26 Revision 0 – February 2009 APPENDIX D Supplemental Fire Protection Review Criteria for Power Uprates The purpose of this appendix is to provide guidance for the review of the fire protection information in an application for a power uprate. Power uprates typically result in an increase in decay heat generation following a plant trip; however, this change usually does not affect the elements of a FPP related to administrative controls, fire suppression and detection systems, fire barriers, the fire protection responsibilities of plant personnel, the procedures and resources necessary for the repair of systems required to achieve and maintain cold shutdown, nor does it usually result in an increase in the
