The staff has identified that fire protection (FP) systems andcomponents have been excluded from the scope of license renewal and an aging management review (AMR). These systems and components were not included in the license renewalboundaries and appear to have FP intended functions required for compliance with Title 10 of the Code of Federal Regulations Part 50.48 (10 CFR 50.48) as stated in 10 CFR 54.4. Inaddition, the staff requests clarification on related technical issues (which may not be addressed in the LRA, thereby raising questions by their omission) which are needed to complete the review. Therefore, the staff requires responses to the following request for additional information (RAI)'s: Section 2.3.3.9 Fire Protection System-Water RAI 2.3.3.9-1 LRA drawings LRA-M-218-SH-01-0, LRA-M-218-SH-06-0, and LRA-M-218-SH-08-0 show thesprinkler and water spray systems for the turbine lube oil storage and conditioning as out ofscope (i.e., not colored in orange). Please verify whether the turbine lube oil storage sprinkler system, conditioning room ceiling sprinkler system, and conditioning pre-action water spraysystem, are in scope of license renewal in accordance with 10 CFR 54.4(a) and subject to anAMR 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, provide justification for the exclusion. RAI 2.3.3.9-2 LRA drawing LRA-M-218-SH-02-0 shows the piping downstream of the city water supply as outof scope. With the city water supply serving as an alternate supply for the fire water system,please confirm and explain whether this line should be in scope for license renewal and subject to an AMR. If not, please explain the basis. RAI 2.3.3.9-3 LRA Table 2.3.3-9 excludes several components shown in color (i.e., in scope) in the LRAdrawing LRA-M-218-SH-01-0. For example, a reducer flange is shown in zone C-4 of the drawing and appears to restrict flow to the associated fire hose station. A blind flange is shown in zone F-6 in the reactor auxiliary bay. "Street box" housing is indicated in zone E-2. Anunknown function or component is indicated by small trapezoid symbols shown mainly in headers upstream of hose stations in several buildings. An unknown function or component is indicated by a semi-circle symbol in zone F-4 located along a 2.5-inch line upstream of two hose stations in the reactor building. Please confirm and explain whether these componentsshould be included in Table 2.3.3-9, as passive components within scope for license renewal and subject to an AMR. If not, please justify the exclusion. RAI 2.3.3.9-4LRA Table 2.3.3-9 excludes several types of FP Water System components that appear in theSE and its supplements and/or UFSAR, and which also appear in the LRA drawings colored in orange. These components are listed below. *hose station*hose connections

• pipe fittings

• couplings

• threaded connections

• restricting orifices

• interface flanges

• chamber housing

• actuator housing (e.g., weight releasing cabinet housing)For each, please determine whether the component should be included in Table 2.3.3.9, and ifnot, please provide the basis for the exclusion. RAI 2.3.3.9-5 LRA Table 2.3.3-9 excludes other component types such as gear boxes, gauge snubbers, etc. Please determine whether these and/or additional component types are in scope and subject to an AMR, and should be included in Table 2.3.3-9. If not, please justify the exclusion.RAI 2.3.3.9-6 LRA Tables 2.4-2, 2.4-3, 2.4-4, and 2.4-6 exclude noncombustible shields and curbs (andscuppers) from the list of structural FP components in scope for license renewal and subject to an AMR. Section 3.1.11 of the SE discusses the use of noncombustible shields between feedwater pumps to prevent oil release from one pump impinging on the other pumps.

Sections 3.1.11 and 4.8 of the SE discuss the use of curbs (and scuppers) in the diesel oil daytank rooms to contain potential oil spills and prevent them from spreading to other fire areas inthe event of an oil fire. Please determine whether noncombustible shields and curbs (and scuppers) should be included as components in scope for license renewal and subject to an AMR.

RAI 2.3.3.9-7LRA Table 2.4-6 excludes smoke seals and fire retardant coatings from the list of structuralbulk commodities components in scope for license renewal and subject to an AMR. The SE supplement dated March 24, 1988, discusses the installation of smoke seals in electrical conduits that pass through fire barriers and between fire areas. Sections 3.2.4 and 4.11 of the SE discuss the use of fire retardant coatings to protect polyvinyl chloride jacketed cables where the cables are not installed in enclosed cable trays. Please determine whether these two components should be in scope and subject to an AMR, and justify exclusion if they are out of scope. RAI 2.3.3.9-8Section 4.3.5 of the SE discusses automatic water spray for the main power transformer,auxiliary transformer, and shutdown transformer. However, LRA drawing LRA-M-218-SH-01-0and LRA-M-218-SH-05-0 show the Main Transformer Sprinkler System, Auxiliary TransformerSprinkler System, Startup Transformer Sprinkler System, and Shutdown Transformer Sprinkler System, as out of scope of license renewal and AMR. Please confirm and explain whether these transformer sprinkler systems should be within scope for license renewal and subject toan AMR.RAI 2.3.3.9-9 Section 4.3.5 of the SE states that new sprinkler systems were proposed for the radwaste truckloading area and the access control area of the radwaste and control building. PNPS UFSAR Section 10.8.3.1 identifies sprinkler system FP for the access control area (i.e., wet pipe) andthe radwaste truck lock area (i.e., dry pipe). However, the LRA drawing LRA-M-218-SH-01-0 shows these areas as out of scope. Please clarify whether these systems are in scope forlicense renewal and subject to an AMR. RAI 2.3.3.9-10 Section 4.8 of the SE discusses floor drains provided in all plant areas protected with fixedwater fire suppression. LRA Section 2.3.3.9 states that structural FP components are reviewedin the structural evaluation for the building in which they are contained or in the structural bulkcommodities review. However, LRA Tables 2.4-2, 2.4-3, 2.4-4, and 2.4-6 do not list floor drainsas a FP component in scope for license renewal or an AMR. Should floor drains be included in scope for license renewal and subject to an AMR? If not, please provide justification for the exclusion.Section 2.3.3.10 Fire Protection System-Halon RAI 2.3.3.10-1 LRA drawing LRA-M-218-SH-04-0 shows a manual pneumatic actuator colored in purple (i.e., inscope). However, the actuator housing is not listed in LRA Table 2.3.3-10. Please clarifywhether actuator housings are in scope and subject to an AMR. If not, please justify the exclusion.RAI 2.3.3.10-2 Section 4.4 of the SE discusses carbon dioxide as a fixed fire suppression system for the cablespreading room, turbine building tank, and hose reels in the switchgear area, reactor feed pump area, and generator area. SE supplements discuss conversion of the carbon dioxide fixed suppression capability to a Halon fixed suppression capability for the cable spreading room andswitchgear area. The status of the other areas (i.e., the turbine building tank and the hosereels in the reactor feed plump and generator areas) is unclear. Please clarify whether fixed suppression exists for these other areas. If there is suppression, please describe the type of suppression provided and explain whether it is in scope and why. RAI 2.3.3.10-3Section 4.4 of the SE states that a total flooding Halon extinguishing system will be installed forthe computer and storage room, and PNPS FSAR Section 10.8.3.2 discusses automatic Halonsuppression for the plant computer room and O&M building record storage vault. However, the LRA drawing LRA-M-218-SH-04-0, does not show the computer and storage room as in scope for license renewal and subject to an AMR. Furthermore, LRA Section 2.3.3-10 states that only passive mechanical components in the cable spreading room Halon system are required forcompliance with 10 CFR 50.48 (fire protection regulations). However, please clarify whether these other areas are protected with automatic Halon suppression.
