ATTACHMENT 1 Nine Mile Point Nuclear Station Responses to NRC Requests for Additional Information (RAI)
Regarding Aging Management of Auxiliary Systems, as Described in Section 3.3 of the License Renewal Application This attachment provides the Nine Mile Point Nuclear Station, LLC (NMPNS) responses to the requests for additional information contained in the NRC letter dated December 27, 2004, regarding aging management of auxiliary systems. Each NRC RAI is repeated, followed by the NMPNS response for Nine Mile Point Unit 1 (NMP1) and/or Nine Mile Point Unit 2 (NMP2), as applicable. Revisions to the License Renewal Application (LRA) are described where appropriate. The revisions are highlighted by shading unless otherwise noted.
RAI 3.3.2-1 In the LRA, the applicant credited an aging management program (AMP), "System Walkdown Program, " to manage the aging effects of cracking and loss of material for non safety-related (NSR) piping, fittings, and equipment for all 24 subsystems of NMPI and NMP2 Auxiliary Systems. The applicant firther stated that the "System WValkdown Program" will manage the aging effects for the above NSR components that are made from any material and exposed to any water environments (e.g., Demineralized Untreated Water, Treated Water or steam with various temperatures, Raw Water, etc.). However, the System Walkdown Program uses only visual inspections to identify the above aging effects. Please provide additional information tofidly explain under what conditions, what sizes of cracks may occur, and what can be identified visually in those 24 subsystems. The staff does not consider leakage detection alone as an adequate AMP because the component has already degraded significantly when it leaks. Please provide justi fication for NMPs conclusion that Ultra-sound Testing (UT) or Eddy Current Testing (ECT) methods are not necessary for detecting cracking aging effects.
Response
As detailed in the response to RAI 3.3.2-2 below, NMPNS has revised the LRA tables for the subsystems of the NMP1 and NMP2 Auxiliary Systems containing non-safety-related (NSR) piping, fittings and equipment. The revisions delete the "Any" material description and replace it with the specific material for these components. The associated environments, aging effects, and aging management programs are also specified. As a result, the Systems Walkdown Program is no longer the only program credited for managing the aging effect of cracking.
While the Systems Walkdown Program can detect surface cracks that are visible to the naked eye Page 1 of 12
as well as leakage and signs of leakage, it cannot detect cracks that originate on the interior surface of components. For those subsystems where cracking was identified as an aging effect for the NSR piping, fittings, and equipment, an appropriate aging management program was credited. For several subsystems, the One-Time Inspection Program was credited since the occurrence of cracking is expected to be insignificant for the period of extended operation.
Based on the revisions to the LRA tables for the subsystems of the NMPl and NMP2 Auxiliary Systems shown in Attachment 2, whereby an aging management program other than the Systems Walkdown Program is credited to manage the aging effect of cracking, the requested information is no longer applicable.
RAI 3.3.2-2 For those 24 subsystems mentioned in RAI 3.3.2-1 above, the staff also finds thatfor the same component exposed to the same or similar environment with the same identified aging effects, one subsystem credits one AMP while the other luses tvo or three AMPs. For example, the NMPI Hydrogen Wrater Chemistry System uses just the System Wralkdown Program, while the NMP2 Process Sampling System uses Water Chemistry Control Program in addition to the System Wralkdowvn Program, and the Reactor Water Cleanup Systems in both NMPI and NMP2 credit three AMPs for each system. Please provide additional infonnation to explain the above discrepancy.
Response
NMPNS recognizes that the proper identification of aging effects and aging management programs (AMPs) may not have occurred by using "Any" material for NSR piping, fittings, and equipment in the subsystems of the NMP1 and NMP2 Auxiliary Systems. Therefore, NMPNS is revising the applicable LRA tables to identify the specific material for the NSR piping, fittings, and equipment for each of the subsystems. The associated environments have also been revised to coordinate with the appropriate material. The aging effects and aging management programs are now aligned with the material-environment combination. This reevaluation has resolved the discrepancy sited in the RAI.
As a result of the reevaluation described above, the NSR piping, fittings, and equipment are assigned programs to adequately manage their aging during the period of extended operation.
The most significant change is that the Systems Walkdown Program is no longer the only AMP credited. In several cases, the One-Time Inspection Program is credited in addition to the Systems Walkdown Program. This is appropriate since the aging effects are expected to be insignificant for the period of extended operation. For example, the NSR piping, fittings, and equipment in the NMPl Miscellaneous Non-Contaminated Vents and Drains System and the NMP2 Process Sampling System are small bore components that may undergo cracking as an aging effect. However, since the extent of any cracking is not expected to affect the pressure boundary intended function of these components, the assignment of the One-Time Inspection Program is appropriate.

I" For other subsystems, the specific identification of the material-environment combination resulted in the determination that no aging effects were applicable. For example, the NSR piping, fittings, and equipment in the NMPI Process Sampling System were determined to be constructed of wrought austenitic stainless steel and exposed to an environment of treated water with a temperature of less than 140'F. For this material-environment combination, there are no applicable aging effects and, therefore, no aging management programs are assigned. This situation also occurred for the NMP1 Shutdown Cooling and Spent Fuel Pool Filtering and Cooling Systems, and the NMP2 Makeup Water and Seal Water Systems. The remaining subsystems of the NMP1 and NMP2 Auxiliary Systems have specific AMPs credited.

The changes to the applicable LRA Section 3.3 tables are shown in Attachment 2.
RAI 3.3.2-3 For several auxiliary subsystems identified in the LRA, the applicant stated that various components of these subsystems are made from copper alloys (Zinc less than or equal to 15%o) and exposed to demineralized untreated water. For these components, the applicant has identified that its aging effects require no management program in order to maintain its pressure boundary integrity; and therefore, no AMPs are credited. Since demineralized water is not treated withi corrosion inhibitors and thus is not chemically treated to remove or add oxygen, please provide additional information to justify NMP's conclusion that components of NMPI and NMP2 auxiliary subsystems require no AMP to manage its aging effects.
In LRA Table 3.3.2.B-10 for NMP2 Diesel Generator Building Ventilation System, the applicant identified the loss of material aging effect for the Unit Cooler. The applicant also stated that components of the Unit Cooler are made from copper alloy (Zinc less than or equal to 15%), and exposed to raw water. Since raw water is also an untreated water, it is not chemically treated to remove or add oxygen. Please provide information to compare and explain the discrepancy betveen the loss of material aging effect that had been identi(fiedfor the Unit Cooler with the above case for the NMPI and NMP2 auxiliary subsystems, with its components are also made from copper alloy (Zinc less than or equal to 15%), the same mnaterialfound in the Unit Cooler, and exposed to demineralized untreated water; but with no identif ed aging effects that require an AMP.
Response
NMPNS acknowledges that there are inconsistencies with the aging management of components made of copper alloys (Zinc less than or equal to 15%) exposed to demineralized untreated water. A review of LRA Section 3.3.2 tables identified four subsystems in the NMP1 Auxiliary Systems with component types having the subject material-environment combination and no aging management program credited. These subsystems are the NMP1 Containment, Control Room HVAC, Reactor Building Closed Loop Cooling, and Spent Fuel Pool Cooling Systems.
The component types are Heat Exchangers, Pumps, and Valves. NMPNS is revising the LRA to Page 8 of 12
identify an aging effect of loss of material and an aging management program of the Closed Cycle Cooling Water System Program. These changes adequately address the discrepancies noted in the RAI and provide for aging management of the subject components.
LRA Revisions LRA Tables 3.3.2.A-4 (page 3.3-115), 3.3.2.A-5 (pages 3.3-120, 121, and 122), 3.3.2.A-15 (page 3.3-157), and 3.3.2.A-21 (page 3.3-182), are revised to incorporate the changes described above, as shown in Attachment 2.
RAI 3.3.2.A-3.1 In LRA Table 3.3.2.A-3 for NMPJ Compressed Air System, the applicant credited the Compressed Air Monitoring Program (CAMP)for managing the aging effects of cracking, hardening, shrinkage, and loss of strengthforpolymers in valves exposed to air environment.
However, the CAMP for NMPI does not include the managemnent of aging effects of polymer hardening, shrinkage, and loss of strength. Please provide information to justify the luse of this aging management program (AMP)for managing the aging effects of polymers by providing the methods of detection, test intervals, acceptance criteria, monitoring, trending, and preventive action, or provide other acceptable AMP.
In LRA Table 3.3.2.A-l for the NMPJ Circulating Water System, the applicant identified polymer cracking and loss of strength as aging effects for traveling screens and rakes exposed to raw water. The applicant also stated that the Open-Cycle Cooling Water System Program is usedfor managing the above identified aging effects. Please provide infonration to explain how the Open-Cycle Cooling Water System Program can manage the above identified aging effects.
Response
(a) Compressed Air Monitoring Program The component type "Polymers" in an environment of "Air" in LRA Table 3.3.2.A-3 refers to ten solenoid valves associated with the Instrument Air Dryers. The aging effects requiring management for the polymers in each of these valves include "Cracking," "Hardening &
Shrinkage," and "Loss of Strength."
The NMP1 Compressed Air Monitoring Program credits an existing Instrument Air Dryer preventive maintenance procedure for managing the aging of these ten solenoid valves.
Currently, this procedure does not include the specific methods of detection, test intervals, acceptance criteria, monitoring, trending, or preventive actions for these valves. This is an identified enhancement which is included in the enhancements listed in LRA Sections Al.1.14 and B2.1.14. The basis for the procedure enhancement will be proven industry practices.
(b) Open-Cycle Cooling Water System Program The component type "Polymers" in a "Raw Water" environment in LRA Table 3.3.2.A-I refers to the fiberglass subcomponents of the Circulating Water System traveling screens and trash Page 9 of 12
rakes. The aging effects requiring management include "Cracking" and "Loss of Strength," both due to the aging mechanism of "Polymer Degradation."
The assignment of the Open-Cycle Cooling Water System (OCCWS) Program for management of aging effects in the NMP1 Circulating Water System is unclear since the inspections will be performed within a preventive maintenance procedure. Therefore, NMPNS is revising LRA Table 3.3.2.A-1 to replace the OCCWS Program with the Preventive Maintenance Program.
NMP1 has an existing procedure that performs preventive maintenance on the traveling screens every six months. However, this procedure does not currently inspect the fiberglass subcomponents (debris catch baskets) for aging effects. NMPNS has identified this procedure as requiring enhancement and will incorporate proven industry techniques to detect cracking and loss of strength. As a minimum, a visual inspection will be performed.
LRA Revisions In LRA Section 3.3.2.A.1 (page 3.3-12), under the "Aging Management Program" heading, "Open-Cycle Cooling Water System Program" is replaced with "Preventive Maintenance Program."
In LRA Table 3.3.2.A-1 (page 3.3-102), the Open-Cycle Cooling Water System Program is replaced with the Preventive Maintenance Program for managing aging effects for the Circulating Water System traveling screens and rakes, as shown in Attachment 2.
RAI 3.3.2.A-4.1 In LRA Table 3.3.2.A-4for NMPI Containment System, the applicant credited the Preventive Maintenance Program (PMP) as an aging management program (AMP)for managing the aging effect of loss of material for valves made from carbon or low alloy steel (yield strength less than 100 ksi) and ductile/malleable cast iron, exposed to air environment. The ten-elements description of the PMP indicates that the PMP is a condition-mnonitoring program perfonned on a specific schedule with specific acceptance criteria establishedfor each component inspection.
Please provide the following infonnation:
(1) For valves in NMP1 Containment System, provide infonnation related to its inspection schedule and acceptance criteria for the inspections; and (2) Componentsfor NMP2 Reactor Building Closed Loop Cooling TVater System are made from the same material (e.g., carbon or low alloy steel (yield strength less than 100 ksi) and ductile/malleable cast iron) and are exposed to a similar environment with similar identified aging effects. Please provide additional informnation to explain and justify why the One-Tine Inspection Program is used instead of the Preventive Maintenance Program.
Response
(1) There are eighteen valves in the NMPl Containment System made of carbon or low alloy steel (yield strength less than 100 ksi) and ductile/malleable cast iron and exposed to air.
Page 10 of 12
Based upon a reevaluation of the extent of aging effects expected, the Preventive Maintenance Program is replaced by the One-Time Inspection Program. The reason for this change is that the aging effect for these valves in air is loss of material due to general corrosion only. Since these valves are exposed to an air environment a majority of the time and a nitrogen environment the remainder of the time, the extent of corrosion expected to occur during the period of extended operation is insignificant. However, to validate this expectation, these valves will be included in the One-Time Inspection Program. They will be included in the grouping of components made of the same material and exposed to the same environment. A sample of these components will be inspected and the results applied to the grouping. If the inspection results show that the loss of material is greater than expected, an evaluation will be performed with respect to placing these components into a periodic inspection program. More information on the One-Time Inspection Program is provided in LRA Section B2.1.20.
Based on the above-described change in aging management programs from the Preventive Maintenance Program to the One-Time Inspection Program, the requested information is considered not applicable.
LRA Revision In LRA Table 3.3.2.A-4 (page 3.3-116), for valves with a material of "Carbon or Low Alloy Steel (Yield Strength < 100 Ksi) and Ductile/Malleable Cast Iron," and an environment of "Air," the Preventive Maintenance Program is replaced with the One-Time Inspection Program, as shown in Attachment 2.
(2) As stated above, the One-Time Inspection Program is the appropriate aging management program for components made of carbon or low alloy steel (yield strength less than 100 ksi) and ductile/malleable cast iron and exposed to an air environment. The applicable aging effect for this material-environment combination is loss of material due to general corrosion.
However, the extent of corrosion is expected to be insignificant for the period of extended operation. As such, the intended function for these components is not expected to be adversely affected due to this aging effect. Therefore, using the One-Time Inspection Program to validate this expectation is appropriate and is consistent with components in several other systems identified in the LRA.
RAI 3.3.2.B-6.1 In LRA Table 3.3.2.B-6for NMP2 Containment Atmosphere Monitoring System, the applicant credited the System WValkdowvn Program for managing the aging effects of cracking and loss of
- materialfor bolting (made from martensitic, precipitation hardenable, and superferritic stainless steels) exposed to air, moisture or wetting, with temperature equal to or greater than 140 degree F environments. Please provide information (1) to explain what sizes of crack may occur in the Containment Atmosphere Monito'ring System that can be identified visually under the System Walkdowvn Program; and (2) to'justify NMP's conclusion that it is not necessary to use the Ultra-sound Testing or Eddy current Testing methods to detect aging effects of cracking.
Page 11 of 12
Response
In NMPNS letter NMP1L 1919, dated January 20, 2005, responses to NRC requests for additional information were submitted regarding the aging management of bolting for NMP1 and NMP2. In this letter, LRA Table 3.3.2.B-6 was revised to replace the Systems Walkdown Program with the Bolting Integrity Program (BIP) for bolting in the NMP2 Containment Monitoring System (CMS). The BIP was added to the LRA and is described in new LRA Section B2.1.36. The BIP is consistent with NUREG-1801, with exceptions and enhancements, and will adequately manage the aging effects of the bolting in the NMP2 CMS system. The exceptions are not related to bolting in the NMP2 CMS system, and the enhancements are not related to the detection of cracking.
RAI 3.3.2.A-17.1 In LRA Table 3.3.2.B-24 for NMP2 Reactor Water Cleanup System, the applicant credited three aging management programs (AMPs), namely, BWR Reactor Water Cleanup System Program, System Walkdowvn Program, and Flow-Accelerated Corrosion Program, for managing the aging effects of cracking and loss of materialfor non safety-related (NSR) piping, fittings, and equipment exposed to five different treated water or steam environments.
In LRA Table 3.3.2.A-17for the NMPJ Reactor Water Cleanup System, tile applicant also credited the same three aging management programs (AMPs) to manage the aging effects for similar NSR piping, fittings, and equipment, but exposed only to treated wvater with temperature less than 140 degree F. Please provide information to explain the above discrepancy.
Response
As described in the NMPNS response to RAI 3.3.2-2 above, the applicable aging effects and AMPs for the NMP1 and NMP2 Reactor Water Cleanup Systems have been revised based upon identifying the specific material for the non-safety-related (NSR) piping, fittings, and equipment component type. The environments have also been revised to be consistent between the two units. Based on the revised material-environment combinations, the applicable aging effects are loss of material and cracking. The associated aging management programs are the BWR Reactor Water Cleanup System, Flow-Accelerated Corrosion, Water Chemistry Control, One-Time Inspection, and Systems Walkdown Programs, except that the BWR Reactor Water Cleanup System Program is not applicable for the NMP2 NSR components. These revisions bring the credited AMPs into consistency between the two units.
