ENCLOSURE 1 Response to November 12, 2009, Request for Additional Information Regarding Fire Protection for the Review of the PVNGS License Renewal Application Response to November 12, 2009, Request for Additional Information for the Review of the PVNGS License Renewal Application NRC RAI 2.3.3.19-1 License renewal application (LRA) drawing LR-PVNGS-FP-01-M-FPP-002 shows transformers in proximity to the turbine building as out of scope (i.e., not colored in green). The staff requests that the applicant verify whether these components are in the scope of license renewal in accordance with Title 10 of the Code of Federal Regulations (10 CFR) Part 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, the staff requests that the applicant provide justification for the exclusion.
APS Response to RAI 2.3.3.19-1 Transformers shown on drawing LR-PVNGS-FP-01-M-FPP-002 at coordinates B-2 through B-7 are electrical components within the scope of license renewal. These transformers are excluded from aging management review in accordance with 10 CFR 54.21(a)(1). NEI 95-10 Appendix B item 104 identifies that transformers are excluded from aging management review under 10 CFR 54.21(a)(1).
These structures, systems, and components (SSCs) were not highlighted on drawing LR-PVNGS-FP-01-M-FPP-002 because those drawings are mechanical boundary drawings and only mechanical components within scope of license renewal are highlighted on mechanical boundary drawings. The scoping and screening methodology for mechanical systems is further detailed in the PVNGS LRA Section 2.1.3.1, and the scoping and screening methodology for electrical systems is further detailed in PVNGS LRA Section 2.1.3.3. A single license renewal drawing, LR-PVNGS-ELEC-E-MAA-001, was created for electrical based on the switchyard'one-line diagram.
NRC RAI 2.3.3.19-2 The following LRA drawings show fire protection system components as out of scope (i.e., not colored in green):
- LRA drawing LR-PVNGS-FP-01-M-FPP-003 shows fire water system valves and drains in the Upper-and Lower Cable Spreading Room and Radwaste Building as out of scope.
LRA drawing LR-PVNGS-FP-01-M-FPP-006 shows fire water system valves and drains as out of scope.
LRA drawing LR-PVNGS-FP-01-M-FPP-001 shows fire water system valves, drains, and fuel tank dikes as out of scope.
1 Response to November 12, 2009, Request for Additional Information for the Review of the PVNGS License Renewal Application The staff requests that the applicant verify whether these fire protection system components 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.
APS Response to RAI 2.3.3.19-2 Ongoing reviews of system branch lines also identified components noted below as within the scope of license renewal and updated system boundary drawings as indicated.
LRA drawing LR-PVNGS-FP-01-M-FPP-003:
LRA drawing LR-PVNGS-FP-01-M-FPP-003 has been revised to reflect that the fire water system valves and drains in the Upper and Lower Cable Spreading Room and Radwaste Building are within the scope of license renewal. The additional components have been highlighted in green on Revision 1 of LRA drawing LR-PVNGS-FP-01-M-FPP-003.
LRA drawing LR-PVNGS-FP-01-M-FPP-006:
LRA drawing LR-PVNGS-FP-01-M-FPP-006 has been revised to reflect that the fire water system valves and drains are within the scope of license renewal, with exception of the valves noted below. The additional components are highlighted in green on Revision 1 of LRA drawing LR-PVNGS-FP-01-M-FPP-006.
The following valves shown on LRA drawing LR-PVNGS-FP-01-M-FPP-006 are not within the scope of license renewal because they are not part of the criteria (a)(3) pressure boundary and do not have a criterion (a)(2) function. Criterion (a)(2) components are non-safety related and are in rooms where there is potential for spatial interaction with safety-related equipment. These valves are not located in rooms with the potential for spatial interaction.
Fire water system Valves not within the scope of license renewal:
V407 & V408, Preaction Valve V711 vent & drain V419 & V420, Preaction Valve V729 vent & drain V421 & V422, Preaction Valve V726 vent & drain V423 & V424, Preaction Valve V723 vent & drain V425 & V426, Preaction Valve V732 vent & drain 2
Response to November 12, 2009, Request for Additional Information for the Review of the PVNGS License Renewal Application LRA drawing LR-PVNGS-FP-AO-M-FPP-001:
(referred to in RAI 2.3.3.19-2 as LR drawing LR-PVNGS-FP-01-M-FPP-001)
LRA drawing LR-PVNGS-FP-AO-M-FPP-001 has been revised to show fire water system valves and drains within the scope of license renewal, with exception of the items noted below. The additional components are highlighted in green on Revision 1 of LRA drawing LR-PVNGS-FP-AO-M-FPP-001.
Portions of the fire water system shown on drawing LR-PVNGS-FP-AO-M-FPP-001 and listed below do not have a criteria (a)(3) function or a criterion (a)(2) function.
Criterion (a)(2) components are non-safety related and are in rooms where there is potential for spatial interaction with safety-related equipment. These valves are not located in rooms with the potential for spatial interaction.
Portions of the Fire Water System not within the scope of license renewal:
Caustic Injection Pump & associated piping and valves Sulfite Injection Pump & associated piping and valves Motor Driven Recirculation Pump & associated piping and valves (for chemical addition)
Fire Water Pump test/recirculation piping and valves Water Reclamation fire suppression piping and valves Chemical Storage Building fire suppression piping and valves Vehicle Maintenance Facility fire suppression piping and valves Station Blackout Gas Turbine General Area fire suppression piping and valves Low Level Radioactive Waste Material Storage Facility fire suppression piping and valves The fuel oil tank dikes are in the scope of license renewal and screened in as generic concrete components in LRA section 2.4.13, Yard Structures. The fuel oil tank dikes are not highlighted in green on LRA drawing LR-PVNGS-FP-AO-M-FPP-001 because they are not mechanical components. Only mechanical components within scope of license renewal are highlighted on mechanical boundary drawings. A single license renewal drawing, LR-PVNGS-STR-OOB-001, was created for structures based on the site plan.
As a result of these changes, LRA Tables 2.3.3-19 and 3.3.2-19 have been revised and are included in Enclosure 2 as LRA Amendment 6. A cast iron orifice for the branch line associated with the jockey pump in the Fire Pump House has been added to LRA Tables 2.3.3-19 and 3.3.2-19. The material for the small diameter system air check valves for preaction valves was corrected from cast iron to copper alloy and resulted in an additional line on LRA Table 2.3.3-19 for the interior environment associated with the copper alloy check valves.
3 Response to November 12, 2009, Request for Additional Information for the Review of the PVNGS License Renewal Application NRC RAI 2.3.3.19-3 LRA drawing LR-PVNGS-FP-01-M-FPP-004 shows several components associated with the carbon dioxide (002) fire suppression system in the Auxiliary Building as out of scope (i.e., not colored in green). The staff requests that the applicant verify whether these C02 fire suppression system components 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.
APS Response to RAI 2.3.3.19-3 LRA drawing LR-PVNGS-FP-01-M-FPP-004 has been revised (Revision 1) to show the following additional components within scope of license renewal (highlighted in green):
Drain valve V380 at coordinate B-5 Switchgear Building 002 hose stations Carbon Dioxide Storage Unit components VE052, VW001, V743, UV1'16 and associated piping The Electric Vaporizer and 002 supply line for the Main Generator purge do not have a license renewal intended function and are not within the scope of license renewal.
NRC RAI 2.3.3.19-4 LRA Table 2.3.3-19 excludes several types of fire protection components that appear in NUREG-0857 and its supplements and LRA drawings. These components are listed below:
Pipe fittings, pipe supports, hangers, and couplings
" Fire hose stations, connections and racks Filter housings Halon 1301 storage bottles
" Dikes for oil spill confinement Floor drains and curbs for fire-fighting water
" Passive components in the diesel fuel fire pump engine For each, determine whether the component should be included in Tables 2.3.3-19 and 3.3.2-19, and, if not, justify the exclusion.

Enclosure I Response to November 12, 2009, Request for Additional Information for the Review of the PVNGS License Renewal Application APS Response to RAI 2.3.3.19-4 Palo Verde evaluated the list of components and determined no changes to the LRA are required as described below.
Pipe fittings and couplings:
Pipe fittings and couplings are evaluated as the component type "piping." This is consistent with the definition of piping, piping components, and piping elements noted in NUREG-1801, Chapter IX.B. The component type of "piping" is identified in LRA Table 2.4-14 as a component within the scope of license renewal and subject to an AMR.
Pipe supports and hangers:
Fire Protection pipe supports and hangers are evaluated as structural component type "Supports Non ASME" and are identified in LRA Table 2.4-14 as components within the scope of license renewal and subject to an AMR.
Fire hose stations, connections and racks:
Fire hose stations, connections and racks are evaluated as component types "piping" and "valve" and are identified in LRA Table 2.3.3-19 as components within the scope of license renewal and subject to an AMR.
Filter housings:
Filter housings are evaluated as part of the component type "Filter" in LRA Table 2.3.3-19 as components within the scope of license renewal and subject to an AMR.
Halon 1301 storage bottles:
The component type of "tank" specified in LRA Table 2.3.3-19 includes Halon 1301 storage bottles within the scope of license renewal and subject to an AMR. This is consistent with the definition of tanks noted in NUREG-1 801 Chapter IX.B.
Dikes for oil spill confinement:
The PVNGS UFSAR Response to Question 9A.86(c) documents that in the diesel generator building, the day tank rooms door curbs are sized to a height to contain the full volume of the day tank and its associated piping. These curbs are evaluated as component type "concrete element" and are identified in LRA Table 2.4-3 as components within the scope of license renewal and subject to an AMR for fire protection. There are no oil containment dikes in the outside areas that are within the scope of license renewal and subject to an AMR. The PVNGS UFSAR, Table 9B.3-1, 5
Response to November 12, 2009, Request for Additional Information for the Review of the PVNGS License Renewal Application Section D. 1(h), documents that all oil filled transformers are located at least 50 feet from any building containing safety-related systems with the exception of the west engineered safety features (ESF) transformer, which is located approximately 48 feet from the 3-hour-rated auxiliary building exterior wall. Therefore dikes for oil spill confinement are not within the scope of license renewal. The PVNGS UFSAR, Section 3.8.4.1.9 documents that the diesel generator fuel oil storage tanks are located underground with approximately 10 feet of earth cover.
Floor drains and curbs for fire-fighting water:
Floor drains are evaluated as component type "piping" and are identified in LRA Table 2.3.3-30 as components within the scope of license renewal and subject to an AMR.
