SHEARON HARRIS NUCLEAR POWER PLANT, UNIT 1 LICENSE RENEWAL APPLICATION REQUESTS FOR ADDITIONAL INFORMATION (RAIs)
RAI 2.3.3.31-3 License renewal application (LRA) drawing 5-G-0055-LRA, Fire Protection System Unit 1, shows the Auxiliary Boiler Fuel Oil Storage Tanks foam fire suppression system as out of scope (i.e., not highlighted). Verify whether the foam fire suppression system and its components are in scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an aging management review (AMR) in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and not subject to an AMR, please provide justification for the exclusion.
RAI 2.3.3.31-4 The Shearon Harris Nuclear Power Plant (HNP) final safety analysis report (FSAR) states that the traveling screens are provided at the intake structure for the removal of larger impurities which may be present in the water. It is not clear from review of Section 2.3.3.31 and Table 2.3.3.27 of the LRA that the traveling water screens are included within the scope of license renewal and subject to an AMR. Traveling screens are typically considered to be passive, long-lived components. Traveling screens are located in a fresh or raw water/air environment and are typically constructed of carbon steel. Carbon steel in a fresh or raw water environment or water/air environment is subject to loss of material, pitting, crevice formation, and microbiologically influenced corrosion, and fouling. Explain the apparent exclusion of the trash racks and traveling screens that are located upstream of the fire pump suctions from the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1).
RAI 2.3.3.31-5 FSAR listed various types of water fire suppression systems provided in the plant fire areas for fire suppression activities. The fire suppression system in various areas are:
Automatic Pre-Action Sprinkler System (Fire Areas: 10-A-CSRA, 12-A-BAL, 12-A-HV&IR, 5-W-BAL, and Turbine Generator-Unit No.1)
Automatic Multi-Cycle Sprinkler System (Fire Areas: 1-A-BAL, 1-A-EPA, 1-A-EPB, 5-F-CHF, 5-F-FPP,1-D-DGA,1-D-DGB,1-D-DTA,1-D-DTB,1-O-PA, and 1-O-PB)
Water Spray System (Fire Area: Turbine Generator-Unit No. 1 and Charcoal Filter Assemblies)
Manual Fluoro-Protein Mechanical Foam System (Fuel Oil Storage Tanks)
Wet-Pipe System Deluge Systems The staff requests that the applicant verify whether the above fire suppression systems installed in various areas of the plant are in the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
RAI 2.3.3.31-6 LRA Table 2.3.3-27 excludes several types of fire protection components that appear in the safety evaluation report and/or FSAR, and which are also highlighted in the LRA drawings.
These components are listed below:
yard fire hydrants interior hose standpipe hose connections and racks manual hose stations pipe fittings pipe supports couplings threaded connections restricting orifices interface flanges chamber housings heat-actuated devices gauge snubbers tank heaters Halon 1301 storage cylinders thermowells water motor alarms expansion joint filter housing gear box housing heat exchangers (bonnet) heat exchangers (shell) heat exchangers (tube) heater housing diesel driven fire pump engines muffler diesel driven fire pump engines intake and exhaust silencers orifices sight glass strainer housing turbocharger housing flexible hose latch door pull box pneumatic actuators actuator housing dikes (contain oil spill) storage tanks for fire water system buried underground fuel oil tanks expansion tank jacket cooling water keepwarm pump and heater lubricating oil collection system components for reactor coolant pump lubricating oil cooler auxiliary lubricating oil makeup tank rocker lubricating oil pump flame retardant coating for cables fire barrier penetration seals fire barrier walls, ceilings, floor, and slabs fire doors fire rated enclosures fire retardant coating for structural steel supporting wall and ceiling For each, determine whether the component should be included in Table 2.3.3.27, and if not, justify the exclusion.
