re an acceptable alternative to the deterministic requirements in NFPA 805, Section 4.2.3. The NRC endorses this guidance only if the conditions identified in Regulatory Position 2.3.2 are met. g. NEI 04-02, Appendix O, provides a sample standard license condition, which the NRC does not endorse. Regulatory Position 3.1 provides an example license condition. h. NEI 04-02, Section 4.6.2, provides a list of key items that a license amendment request should include. NEI 04-02, Appendix H, provides a license amendment template. The information provided may not be complete; for example, the list in NEI 04-02, Section 4.6.2, does not include submitting information to support the quality of the PRA models or the use of such models in RG 1.205, Revision 2, Page 8 performing NFPA 805 risk assessments. The licensee should ensure that it submits sufficient information required by applicable regulations and needed for the NRC to make its safety finding on the application. i. Subsequent to publication and endorsement of NEI 04-02, Revision 2, the industry developed and the NRC approved a number of NFPA 805 frequently asked questions (FAQs) related to fire PRA and fire PRA FAQs in RG 1.205, Revision 1, “Risk Informed, Performance-Based Fire Protection for Existing Light-Water Nuclear Power Plants,” issued December 2009 (Ref. 17). NEI 04-02, Revision 3, does not include the content of these FAQs, since they are related to fire PRAs. However, a table in NEI 04-02, Revision 3, Appendix M, lists their respective NRC-authored closure memoranda. Licensees should be aware that the information in this table may be incomplete or outdated. For example, subsequent NRC guidance may have modified or superseded an FAQ. This RG endorses neither the table nor the closure memoranda. 2. License Transition Process 2.1 Transition Schedule In 10 CFR 50.48(c), the NRC does not mandate a specific schedule for implementing an FPP that meets the provisions of NFPA 805. However, the Statement of
