COLUMBIA GENERATING STATION LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION RAI 2.3.3.22-1 License renewal application (LRA) drawing LR-M515-1, shows that several yard fire hydrants and post indicator valves are out of scope (i.e., not colored in green). The staff believes that yard fire hydrants and post indicator valves have the fire protection intended functions required to be compliant with 10 CFR 50.48 as stated in 10 CFR 54.4. The fire hydrants also serve as the pressure boundary for the fire protection water supply system. Further, NUREG-0892, Safety Evaluation Report related to the operation of WPPSS Nuclear Project No. 2, dated March 1982, Section 9.5.1.6, Fire Detection and Suppression, on page 9-33, states that fire hydrants are provided on the yard main at 300-foot intervals. A hydrant hose house is provided at each hydrant with 200 feet of 2 1/2 in. hose and other equipment. A valve is provided in each hydrant lateral to facilitate hydrant maintenance and repair without interrupting flow in the underground pipe loop. The staff requests that the applicant verify whether the yard hydrants and valves are in the scope of license renewal in accordance with 10 CFR 54.4(a) and whether they are 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 are not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.

RAI 2.3.3.22-2 The fire protection components including jockey pump (FP-P-3), valves, piping, and fittings are not highlighted in the LRA drawing LR-M515-1 as components within the scope of license renewal and subject to an AMR. Further, NUREG-0892, Safety Evaluation Report related to the operation of WPPSS Nuclear Project No. 2, dated March 1982, Section 9.5.1.6, Fire Detection and Suppression, on page 9-33, states that a separate jockey pump, rated at 50 gpm at 100 psig, maintain[s] the yard fire main pressure at 100 to 125 psig. The staff believes that these fire protection components perform a pressure boundary intended function consistent with rest of the fire protection system in scope. The staff requests that the applicant verify whether the fire protection components listed above are in the scope of license renewal in accordance with 10 CFR 54.4(a) and whether they are subject to an AMR in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and are not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.

RAI 2.3.3.22-3 LRA drawing LR-M515-1, shows that several fire suppression systems (Building 5, Building 6, and Building 8) are out of scope (i.e., not colored in green). The staff requests that the applicant verify whether these fire water suppression systems installed in various buildings 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 2.3.3.22-6 LRA Section 2.3.3.22, on page 2.3-93, states that the low pressure carbon dioxide system automatically provides fire protection for turbine generator exciter housing. A manual carbon dioxide hose station, with reel and hose, is also provided for exciter housing protection on the turbine generator floor. The automatic carbon dioxide (CO2) fire suppression system and manual CO2 hose station, with reel and hose, do not appear in LRA drawings as being in the scope of the license renewal and subject to an AMR. The staff requests that the applicant verify whether these CO2 fire suppression features 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 2.3.3.22-7 LRA Section 2.3.3.22, on page 2.3-93, states that Halon 1301 suppression systems are installed in normally occupied areas where the application of water would be inappropriate.

Halon 1301 provides automatic fire protection for the main control room Power Generation Control Cabinet (PGCC) under the floor. Eighteen Halon 1301 system[s] are installed in various main control room PGCC sub-floor duct sections to discharge on activation of their associated thermal detector units. The eighteen main control room PGCC Halon 1301 fire suppression systems do not appear in LRA drawings as being in the scope of the license renewal and subject to an AMR. The staff requests that the applicant verify whether these Halon 1301 fire suppression systems 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 2.3.3.22-8 LRA Section 2.3.3.22, on page 2.3-94, states that A dry chemical system is installed in approved portable hazardous material storage buildings within the plant.

RAI 2.4.13-1 LRA Section 2.1.2.2, Screening of Structures, provides the methodology for determining the structures and components including fire barriers within the scope of license renewal. LRA Section 2.4.13, Bulk Commodities, and Table 2.4-13 provide the results of scoping and screening of structures including fire barriers. However, scoping and screening results do not provide the type of fire barriers present in various fire areas of the plant. The staff requests that the applicant provide details of fire barrier type and material in each plant fire area within 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).
