mance-based schedule. DG-1359, Page 31 1.7.10.1 Annual Fire Protection Audit For those licensees who have relocated audit requirements from their technical specifications to the QA program, the annual fire protection audit frequency may be changed if a performance-based schedule is used. American National Standards Institute/American Nuclear Society (ANSI/ANS) 3.2-2006, “Administrative Controls and Quality Assurance for the Operational Phase of Nuclear Power Plants” (Ref. 47), should be used in establishing the audit frequency. The annual audit should incorporate the following elements: a. Purpose: The purpose of the annual audit is to assess the plant fire protection equipment and program implementation to verify that a level of safety consistent with NRC guidelines continues to be provided. b. Scope: Each audit should verify that the commitments of the safety analysis report and the requirements of the technical specifications and license conditions have been met and that modifications to systems and structures or changes in operating procedures have not decreased the level of safety in the plant. The audit should include an inspection of all plant areas for which fire protection is provided and, in particular, examination of fire barriers, fire detection systems, and fire extinguishing systems provided for equipment important to safety. The audit should verify the following: (1) The installed fire protection systems and barriers are appropriate for the SSCs important to safety, based on a comparison with NRC regulatory requirements and the approved FPP. Deviations should be noted. (2) The fire hazard in each fire area has not increased above that specified in the safety analysis report. (3) Regularly scheduled maintenance is performed on plant fire protection systems. (4) Identified deficiencies have been promptly and adequately corrected. (5) Special permit procedures (hot work, valve positioning) are being followed. (6) Plant personnel receive appropriate
