Licensees may use PRA and/or risk insights gained from other methods in support of proposed changes to the plant licensing basis, such as license amendment requests per 10 CFR Part 50, §50.90 and §50.92. Regulatory Guide 1.174, “An Approach for Using Probabilistic Risk Revision 4 - October 2003 57 Assessment In Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis,” provides guidelines for the use of PRA in support of plant changes that require NRC approval. Plant changes that are not subject to NRC approval are not within the scope of Regulatory Guide 1.174. Where PRA is used by licensees in support of submittals to change the plant licensing basis, the guidelines of SRP Chapter 19 should be followed. Revision 4 - October 2003 58 APPENDIX E: 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 to be provided in an application for a power uprate. Power uprates typically result in an increase in decay heat generation following a plant trip, this change usually does not affect the elements of a fire protection program 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, or result in an increase in the potential for a radiological release resulting from a fire. The licensee’s submittal should confirm that the power uprate results in no changes to these elements and this should be reflected in the staff’s safety evaluation. If the licensee indicates that there is an impact on these elements the staff should review the impact against the acceptance criteria in the applicable sections of this BTP to ensure that the Commission’s fire protection goals are satisfied. The systems relied upon to achieve
