REQUESTS FOR ADDITIONAL INFORMATION (RAI)
Fire Protection System RAI 2.3.3.14-1 The LRA drawings listed below show fire protection system components not highlighted in green indicating that they are outside the scope of license renewal. The staff requests that the applicant verify whether these components are within the 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 not, the staff requests that the applicant provide a justification for their exclusion.
(a) LR-WCGS-KC-M-0022-1, Plant Service Water System, shows the following components outside the scope of license renewal:
one out of the four vertical pumps (1WS002P) and its associated components several flow drains (1W30102, 1W30103, etc.)
(b) LR-WCGS-KC-M-0023-1, Fire Protection Water System, shows the following components outside the scope of license renewal:
fire hydrant (1FP0138) and its associated components several flow drains (c) LR-WCGS-KC-M-0023-2, Fire Protection System, shows the following components outside the scope of license renewal:
several valves (d) LR-WCGS-KC-M-0028, Diesel Oil System, shows the following components outside the scope of license renewal:

(g) LR-WCGS-KC-M-12KCO3, Fire Protection System, shows the following components outside the scope of license renewal:
several drain valves RAI 2.3.3.14-2 NUREG-0881, Supplement 5, Section 9.5.1.1, states that the fire pumps take suction from a common wet pit sump in the circulating water screenhouse. Two traveling water screens and the bar grill are located at the inlet to the sump serving the fire pumps. LRA Section 2.3.3.14 and Table 2.3.3.14 do not clearly state whether the traveling water screens and bar grill are included within the scope of license renewal. The staff requests that the applicant verify whether the traveling water screens and bar grill and their associated components are within 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 not, the staff requests that the applicant provide a justification for their exclusion.
RAI 2.3.3.14-3 NUREG-0881, Supplement 5, Section 9.5.1.2, states that where safe-shutdown equipment is enclosed by a fire barrier, all walls, ceilings, floors, and associated penetrations that enclose the equipment have a minimum fire rating of three hours. LRA Section 2.3.3.14 and Table 2.3.3.14 do not clearly state whether fire barrier walls, ceilings, floor, slabs, and associated penetration seals are included within the scope of license renewal. The staff requests that the applicant verify whether these fire barrier walls, ceilings, floor, slabs, and associated penetration seals are within 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 not, the staff requests that the applicant provide a justification for their exclusion.
RAI 2.3.3.14-4 LRA Table 2.3.3-14 excludes several types of fire protection components that are listed in NUREG-0881, Supplement 5, and/or the plants Updated Safety Analysis Report (USAR). In addition, the LRA drawings highlighted them in green as components within the scope of license renewal. The staff requests that the applicant verify whether the component listedbelow should be included in LRA Table 2.3.3.14. If not, the staff requests that the applicant provide a justification for their exclusion.

The staff requests that the applicant verify whether the fire water suppression systems in the areas listed below are within 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 not, the staff requests that the applicant provide a justification for their exclusion.

USAR Table 9.5.1-2 also discusses the total flooding Halon 1301 fire suppression system for non-vital switchgear and transformer rooms, control cabinets, and load centers. However, the total flooding Halon 1301 fire suppression system for non-vital switchgear and transformer rooms, control cabinets, and load centers does not appear in LRA Section 2.3.3.14 as within the scope of the license renewal. The staff requests that the applicant verify whether the total flooding Halon 1301 fire suppression system for non-vital switchgear and transformer rooms, control cabinets, and load centers are within 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 not, the staff requests that the applicant provide a justification for their exclusion.
