” resulting in something different from that described in the FSAR, or is modified to something that differs from the FSAR, the condition should be considered a change and a change evaluation should be performed. 1.8.1.5 Reporting Guidelines The licensee should maintain records of FPP-related changes to the facility, changes in procedures, and tests and experiments made in accordance with the standard fire protection license condition. These records should include a written evaluation that provides the bases for the determination that the change does not adversely affect safe-shutdown capability. The licensee should maintain, in retrievable form, a current record of all such changes and should make such records available to NRC inspectors upon request. All changes to the approved program should be reported, along with the FSAR revisions required by 10 CFR 50.71(e). In accordance with 10 CFR 50.48, the licensee must maintain records of all changes in the facility until the termination of the license. Records of superseded procedures must be maintained for 3 years from the date the record was superseded. 1.8.2 Exemptions to Appendix R to 10 CFR Part 50 For plants licensed before January 1, 1979, the NRC requires requests for exemption from the requirements of Appendix R for modifications or conditions that do not comply with the applicable sections of Appendix R. The exclusion of the applicability of sections of Appendix R other than Sections III.G, III.J, and III.O (and Section III.L, as applicable) is limited to those features accepted by the NRC staff as satisfying the provisions of Appendix A to BTP APCSB 9.5-1 reflected in staff fire protection SERs issued before the effective date of the regulation. For these previously approved features, the NRC does not require an exemption request, except for proposed modifications that would alter previously approved features used to satisfy NRC requirements.
