during non-power operations (NPOs). As stated in RG 1.205, Regulatory Position 2.2.5, Section 4.3.3 and Appendix F to NEI 04-02 provide detailed guidance on one acceptable approach to addressing fires during non-power operational modes. Approved FAQ 07-0040, Revision 4, provides updated language to the NEI 04-02 sections. The staff will review the LAR to verify that the licensee has demonstrated that the nuclear safety performance criteria are met during High(er) Risk Evolutions (HREs). One way to accomplish this objective is for the staff to verify that the licensee has adequately documented the completion of the tasks in Appendix F to NEI 04-02. III.4 RADIOACTIVE RELEASE PERFORMANCE CRITERIA NFPA 805 includes radioactive release goals, performance objectives, and performance criteria in Sections 1.3.2, 1.4.2, and 1.5.2. The staff will verify that the LAR documents that radiation release to any unrestricted area due to the direct effects of fire suppression activities (but not involving fuel damage) remains as low as reasonably achievable, not to exceed the limits in 10 CFR Part 20. Appendix G to NEI 04-02 provides items for the staff to consider as part of this review. III.5 RISK ASSESSMENTS AND PLANT CHANGE EVALUATIONS NFPA 805 requires risk assessments to be performed in several instances: 1. Plant Change Evaluations [NFPA 805, Section 2.4.4] 2. Additional risk associated with RAs [NFPA 805, Section 4.2.4] 3. Fire Risk Evaluations [NFPA 805, Section 4.2.4.2] Staff review guidance for the risk assessments (1, 2, and 3 above) is provided in SRP Paragraphs III.5.3, III.5.4, and III.5.5, respectively. III.5.1 PRA Technical Adequacy The staff will confirm the licensee has provided an evaluation of the technical adequacy of its PRA model consistent with RG 1.200 and SRP Section 19.1. The staff will confirm that the licensee has provided a description of its processes for assuring the PRA model is maintained 9.5.1.2-15 Rev. 0 – December 2009 and updated to reflect
