Dear Mr. Crane:

On March 31, 2006, the NRC completed the onsite portion of the inspection of your application for license renewal of your Oyster Creek Generating Station. The inspection continued in our Region I office until early September 2006. The enclosed report documents the results of the inspection, which were discussed on September 13, 2006, with members of your staff in an exit meeting open for public observation at the Lacey Township Town Hall.

The purpose of this inspection was to examine the plant activities and documents that supported the application for a renewed license of Oyster Creek Generating Station. The inspection reviewed the screening and scoping of non-safety related systems, structures, and components, as required in 10 CFR 54.4(a)(2), and determined whether the proposed aging management programs are capable of reasonably managing the effects of aging. These NRC inspection activities constitute one of several inputs into the NRC review process for license renewal applications.

The inspection team concluded screening and scoping of non-safety related systems, structures, and components, was implemented as required in 10 CFR 54.4(a)(2), and the aging management portion of the license renewal activities were conducted as described in the License Renewal Application. The inspection results support a conclusion that the proposed activities will reasonably manage the effects of aging in the systems, structures, and components identified in your application. The inspection concluded the documentation supporting the application was in an auditable and retrievable form.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS).

4. OTHER ACTIVITIES (OA) 4OA2 Other - License Renewal

a. Inspection Scope This inspection was conducted by NRC Region I and headquarters based inspectors in order to evaluate the thoroughness and accuracy of the screening and scoping of non-safety related systems, structures, and components, as required in 10 CFR 54.4(a)(2) and to evaluate whether aging management programs will be capable of managing the identified aging effect in a appropriate manner.

The inspection team selected a number of systems for review, using the NRC accepted guidance, in order to determine if the methodology applied by the applicant appropriately captured the non-safety systems affecting the safety functions of a system, component, or structure within the scope of license renewal.

The inspection team selected a sample of aging management programs to verify the adequacy of the applicants documentation and implementation activities. The selected aging management programs were reviewed to determine whether the proposed aging management implementing process would adequately manage the effects of aging on the system.

The inspectors reviewed supporting documentation and interviewed applicant personnel to confirm the accuracy of the license renewal application conclusions. For a sample of plant systems and structures, inspectors performed visual examinations of accessible portions of the systems to observe aging effects.

a.1. Scoping of Non Safety-Related Systems, Structures, and Components To assess the thoroughness and accuracy of the methods used to bring systems, structures, and components within scope of the application and to screen non-safety related systems, structures, and components, as required in 10 CFR 54.4(a)(2), the inspectors reviewed the applicants program guidance procedures and summaries of results for Oyster Creek. The inspectors determined the applicants procedures to be consistent with the NRC accepted guidance in Sections 3, 4, and 5 of Appendix F to NEI 95-10, Revision 5 (3: non-safety related systems, structures, and components within scope of the current licensing basis, 4: non-safety related systems, structures, and components directly connected to safety-related systems, structures, and components, and 5: non-safety related systems, structures, and components not directly connected to safety-related systems, structures, and components). Also, the inspectors determined that the applicant appropriately utilized the guidance in their process for determining which systems were within scope.

Enclosure

2 The applicant based the scoping and screening results on a technical review and walkdown of all applicable plant areas by qualified plant personnel. The inspectors reviewed the set of license renewal drawings, which were color-coded based on the results. The inspectors interviewed personnel and independently inspected numerous areas within the plant to confirm that appropriate systems, structures, and components had been included within the license renewal scope, that systems, structures, and components excluded from the license renewal scope had an acceptable basis, and that the boundary for determining scope within the systems, including anchors, was appropriate. For systems, structures, and components selected from the results, the inspectors confirmed that the in-plant configuration was accurate and acceptably categorized, and for systems, structures, and components selected within the plant, the inspectors confirmed that the categorization result in program documents was appropriate. The in-plant areas and systems reviewed included the following:

• Reactor Building;

• Turbine Building;

• Intake Structure;

• Ventilation Stack;

• Diesel Generator Building;

• Diesel Fuel Oil Building;

• Fire Protection System;

• Isolation Condenser System;

• Hardened Vent System;

• Nitrogen Supply System;

• Instrument Air System; and

• Service Water System.

The inspectors determined the personnel involved in the process were knowledgeable and appropriately trained, and that the applicant had implemented an acceptable method of scoping and screening of non-safety related systems, structures, and components.

a.2. Programs One-Time Inspection Program The One-Time Inspection Program is a new aging management program intended to verify the effectiveness of other aging management programs, including Water Chemistry, Closed Cycle Cooling Water Systems, and Fuel Oil Chemistry Programs, by reviewing various aging effects for impact. Where corrosion resistant materials and/or non-corrosive environments exist, the One-Time Inspection Program is intended to verify that an aging management program is not needed during extended operations by confirming that aging effects are not occurring or are occurring in a manner that does not affect the safety function of systems, structures, and components within the scope of the application. Non-destructive evaluation will be performed by qualified personnel using procedures and processes consistent with the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME) and 10 CFR 50, Appendix B. The Enclosure

3 One-Time Inspection Program will be implemented prior to the period of extended operation.

The inspectors reviewed the program description, implementation plan, and inspection sample basis, and discussed the planned activities with the responsible staff.

For the One-Time Inspection Program, the inspectors concluded the applicant performed adequate evaluations and reviews of industry experience and plant history to determine an acceptable approach to identifying, assessing and managing any aging effects detected. The applicant developed adequate guidance for implementation of the One-Time Inspection Program.

Bolting Integrity The Bolting Integrity Program is an existing program credited with managing the loss of material, cracking, and loss of prestress aging effects in safety-related bolting at Oyster Creek. The aging effects are managed by visual inspection for leakage during system pressure tests, normal plant operation, and periodic system maintenance, and repaired in accordance with maintenance procedures and the ASME Code.

The inspectors reviewed the program basis document, implementing procedures, documented reviews, and a bolting-related apparent cause evaluation, and interviewed the responsible plant personnel regarding these documents. In addition, the inspectors walked down portions of the Standby Liquid Control, Isolation Condenser, Control Rod Drive, and Reactor Building Closed Cooling Water Systems to confirm that the program had maintained acceptable bolting conditions.

For the Bolting Integrity Program, the inspectors concluded that the applicant had performed adequate evaluations as well as industry experience and historical reviews to determine the aging effects are managed by the Bolting Integrity Program. The applicant provided adequate guidance to ensure the aging effects are appropriately managed.

Buried Piping Inspection The Buried Piping Inspection Program is an existing program credited with managing the loss of material aging effects on the external surfaces of piping in a soil environment, including the service water, emergency service water, and condensate transfer systems. The aging effects are managed by preventive measures, i.e.,

coatings, wrapping, and condition monitoring measures, including visual inspections and periodic system pressure testing. As described in Appendix B, Part 1.26 of the application, the applicant plans to enhance the program by augmenting the visual inspections prior to extended operations and performing periodic visual inspections, and to include additional piping, such as the fire protection system.

Enclosure

4 The inspectors reviewed the program basis document, system drawings, implementing procedures, and documented reviews, and interviewed the responsible plant personnel regarding these documents. Also, the inspectors walked down the service water and emergency service water systems in the vicinity of buried piping.

For the Buried Piping Inspection Program, the inspectors concluded that the applicant had performed adequate evaluations as well as industry experience and historical reviews to determine the aging effects managed by the Buried Piping Inspection Program. The applicant provided adequate guidance to ensure the aging effects are appropriately managed.

Flow-Accelerated Corrosion Program The Flow-Accelerated Corrosion Program is an existing program credited with managing the corrosion aging effects in all carbon steel piping and components containing high-energy fluids at Oyster Creek Generating Station. The aging effects are managed by using ultrasonic and radiographic testing to detect wall thinning and by predicting wear rates to support the proactive replacement of system piping. In addition, the program provides for the performance of follow-up inspections to confirm predictions and to determine the need for repairs or replacements as necessary.

The inspectors reviewed the piping ultrasonic testing wall thickness results from previous inspections and reviewed the CHECWORKS computer analysis of the future wall thickness forecasts. The inspector also reviewed recent changes to the CHECWORKS model to ensure previously identified deficiencies have been corrected.

The inspectors noted that recent replacements, initiated as a result of this program, were implemented preventively due to identified flow-accelerated corrosion. The replacement piping material was more resistant to corrosion than the original piping material.

For the Flow-Accelerated Corrosion Program, the inspectors concluded the applicant conducted adequate evaluations as well as industry experience and historical reviews and, as a consequence, the effects of aging will be reasonably managed by the proposed program.

Water Chemistry Program The Water Chemistry Program is an existing program credited with managing the effects of aging on piping, piping components, piping elements, and systems, such as the condensate and feedwater, and condensate storage tank in Oyster Creek Generating Station. The aging effects are managed by monitoring and control of reactor water chemistry to minimize contaminant concentration and mitigate loss of material due to general, crevice and pitting corrosion and cracking caused by stress corrosion cracking.

Enclosure

5 Water chemistry control is administered in accordance with the Boiling Water Reactor Vessel and Internals Project guideline BWRVIP-29 and Electric Power Research Institute guideline EPRI TR-103515. The inspectors reviewed the chemistry procedures and sampling results to confirm that the guidance contained in BWRVIP-29 and EPRI TR-103515 was being implemented.

For the Water Chemistry Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Closed-Cycle Cooling Water Systems Program The Closed-Cycle Cooling Water Systems Program is an existing program credited with managing loss of material, cracking, and buildup-of-deposit aging effects in components exposed to closed-cycle cooling water environments at the Oyster Creek Generating Station. Systems within the scope of the closed-cycle cooling water program include the turbine building closed cooling, reactor building closed cooling, and emergency diesel generator closed cooling water systems. The aging effects are managed by monitoring and control of cooling water chemistry, performing surveillance tests, and through periodic inspection of system components in a manner consistent with EPRI TR-107396 guidelines.

The inspectors observed cleaning of the turbine closed-cooling water heat exchanger and performed a walkdown of the system with plant personnel. In addition, the inspectors reviewed closed-cycle cooling water chemistry procedures and reviewed past chemistry sample results to confirm that the requirements of EPRI TR-107396 are being met.

For the Closed-Cycle Cooling Water Systems Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

10 CFR Part 50, Appendix J Program The 10 CFR Part 50, Appendix J Program is an existing program credited with managing the aging degradation of pressure retaining boundaries of piping and components of the various systems penetrating the containment at the Oyster Creek Generating Station. In addition, the program also detects age related degradation in material properties of gaskets, o-rings, and packing materials for the primary containment pressure boundary access points. The aging effects are managed by performing containment leak rate tests to assure that leakage through primary containment and systems and components penetrating primary containment does not exceed allowable leakage limits specified in the Technical Specifications.

Enclosure

6 The inspectors reviewed Oyster Creeks procedures for leak rate testing. In addition, the inspectors reviewed corrective actions for components that did not meet leak rate test acceptance criteria. The inspectors noted that corrective actions taken to repair these components were acceptable.

For the 10 CFR Part 50, Appendix J Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Fuel Oil Chemistry Program The Fuel Oil Chemistry Program is an existing program that will be modified for the purpose of managing the affects of pitting and corrosion in the diesel fuel oil tank at the Oyster Creek Generating Station. The aging effects are managed by the addition of biocides and corrosion inhibitors to minimize biological activity and mitigate corrosion, periodic cleaning, and applying coating to the internal surfaces of the tank.

The inspectors reviewed the schedule for implementation of the enhancements. The inspectors reviewed recent sample results and tank thickness measurements to verify that results were within the acceptable range.

For the Fuel Oil Chemistry Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Boiling Water Reactor Feedwater Nozzle Program The Boiling Water Reactor Feedwater Nozzle Program is an existing program that will be modified to implement the recommendations of the Boiling Water Owners Group Licensing Topical Report: General Electric NE-523-A71-0594. These enhancements will be implemented prior to entering the period of extended operation per Oyster Creek Assignment Report AR# 00330592, A.1.05 Commitment (BWR Feedwater Nozzle). The program is credited with managing the aging effects of cracking in the feedwater nozzles. The program is administered by the station in-service inspection plan ER-OC-330-1001, ISI Program Plan Fourth Ten-Year Inspection Interval, and implemented by station procedure ER-AA-330-002, In-service Inspection of Section XI Welds and Components. The station in-service inspection program incorporates the requirements of the ASME Code. The aging effects are managed by periodic ultrasonic testing inspections of critical regions of the feedwater nozzles. The ultrasonic test inspections are performed at intervals not exceeding ten years and was embraced in an NRC safety evaluation.

Enclosure

7 Inspections performed in 1977 identified cracks in the Oyster Creek nozzles. These cracks were repaired. The inspectors reviewed plant modification #166-76-4, Feedwater Nozzle Cladding Removal and Sparger Replacement and reviewed selected ultrasonic testing examination reports of the feedwater nozzles. To minimize thermal cycling and fatigue induced cracking, the thermal sleeves were modified to a piston design. Subsequent inspections found no indications in the feedwater nozzles.

The inspectors reviewed Focused Area Self-Assessment Report Oyster Creek Inservice Inspection Program, completed in June 2004. The inspectors determined the feedwater nozzle program at Oyster Creek effectively monitored the feedwater nozzles for cracking.

For the Boiling Water Reactor Feedwater Nozzle Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Boiling Water Reactor Stress Corrosion Cracking Program The Boiling Water Reactor Stress Corrosion Cracking Program is an existing aging management program credited with managing crack initiation and growth due to intergranular stress corrosion cracking in stainless steel and nickel alloy reactor coolant pressure boundary piping, welds, components and piping four inches and larger nominal pipe size exposed to reactor coolant above 200EF. The aging effects are managed by preventive measures which include monitoring and controlling water impurities by improved water chemistry control activities and by providing replacement stainless steel components in a solution annealed condition with a maximum carbon content of 0.035%

wt. and a minimum ferrite level of 7.5%. Inspection and flaw evaluations are conducted in accordance with Oyster Creek in-service inspection program plan ER-OC-330-1001, ISI Program Plan Fourth Ten-Year Inspection Interval and Oyster Creeks augmented inspection program for IGSCC ER-OC-330-1002, IGSCC Inspection Plan Fourth Ten-Year Inspection Interval, which incorporates the technical basis and guidance described in NUREG-0313, NRC Generic Letter 88-01, and staff-reviewed Boiling Water Reactor Vessel Internal Inspection Program BWRVIP-75.

The inspectors noted that where pre-emptive piping replacement was accomplished the replacement piping material used was more resistant to intergranular stress corrosion cracking than the original piping material. The applicant replaced the following system piping material with intergranular stress corrosion cracking resistant material:

1) all isolation condenser large bore piping outside the drywell from the drywell penetrations to the isolation condensers during refueling outage 1R13 in 1991;

2) all piping within the four isolation condenser drywell penetrations and the two reactor water cleanup system drywell penetrations which contained welds that were not inspectible;

3) the head cooling spray nozzle assembly, the 4 inch tee and flange of the reactor vent line.

Enclosure

8 To further mitigate the initiation and propagation of intergranular stress corrosion cracking the applicant implemented hydrogen water chemistry during cycle 12 in 1990 and noble metals chemical additions during 1R19 refueling outage in 2002.

Additionally, all accessible welds susceptible to intergranular stress corrosion cracking in reactor coolant boundary piping systems inside the drywell (except the reactor water cleanup system) were stress improved.

The Boiling Water Reactor stress corrosion cracking aging management program uses ultrasonic testing to detect intergranular stress corrosion cracking flaws in the reactor coolant boundary piping prior to loss of intended functions of the components. Of the 380 welds included in the scope of Generic Letter 88-01, Oyster Creek identified, during the period the program was implemented, there were 11 welds with indications of intergranular stress corrosion cracking. Nine welds have been repaired with full structural overlays (four in the core spray system, four in the reactor recirculation system, and one in the shutdown cooling system). Two reactor recirculation system welds, which were both stress improved before initial inspections had indications of intergranular stress corrosion cracking, remained in service without repair. Both of these welds in the reactor recirculation system have been re-examined in 2002 and 2004 using the Improved Performance Demonstration Initiative ultrasonic test examination technique and the welds did not exhibit any indication of intergranular stress corrosion cracking. No new indications of intergranular stress corrosion cracking have been detected by inspections during the past six refueling outages. As a result of the implemented preventive measures to mitigate intergranular stress corrosion cracking Oyster Creek has no indications of intergranular stress corrosion cracking at this time.

Therefore the inspectors determined that the Boiling Water Reactor Stress Corrosion Program at Oyster Creek has been effective in monitoring and mitigating intergranular stress corrosion cracking in the reactor coolant boundary piping systems.

For the Boiling Water Reactor Stress Corrosion Cracking Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Periodic Inspection Program The Periodic Inspection Program is a new program under development at Oyster Creek that consists of periodic inspections of selected systems in the scope of license renewal that require periodic monitoring of aging effects, and are not covered by other existing periodic monitoring programs to verify the integrity of the systems and confirm the absence of identified aging effects. The Periodic Inspection Program manages the aging effect of change in material properties, loss of material and reduction of heat transfer for systems, components, and environments. The aging effects are managed by periodic condition monitoring examinations performed at susceptible locations in the systems, intended to assure that existing environmental conditions are not causing material degradation that could result in a loss of system intended functions. The initial periodic inspections of this new aging management program will be implemented near Enclosure

9 the end of the current operating term but prior to the period of extended operation.

Subsequent periodic inspections will be performed on a frequency not to exceed once every ten years.

The Periodic Inspection Program provides inspection criteria, requires evaluation of the inspection results, and provides recommendations for additional inspections, as necessary. Inspections will be performed in accordance with station procedures that are based on applicable codes and standards. Inspection methods may include visual examinations VT-1 or VT-3 of disassembled components or volumetric non-destructive examination techniques. Some of the implementing procedures for the Periodic Inspection Program were reviewed by the inspectors, including existing nondestructive examination procedures ER-OC-330-1001, ISI Program Plan Fourth Ten-Year Inspection Interval, ER-AA-35-014, VT-1 Visual Examinations, ER-AA-335-016, VT-3 Visual Examination of Component Supports and Attachments, and ER-AA-335-032, Ultrasonic Through Wall Sizing in Pipe Welds. A periodic inspection table, which was in draft at the time of this inspection, is a listing of selected systems and components to be periodically inspected to verify the integrity of the system and confirm the absence of identified aging effects was also reviewed. Based on review of the implementing documents and procedures, the inspectors determined that the Periodic Inspection Program, when implemented at Oyster Creek, will provide assurance that systems and components are routinely inspected for age related degradation of change in material properties, loss of material and reduction of heat transfer for systems, components, and environments, and will adequately manage the identified aging effects.

For the Periodic Inspection Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Wooden Utility Pole Program The Wooden Utility Pole Program is a new program credited with managing the aging effects of loss of material and change in material properties in all wooden utility poles which support an intended function for the offsite power systems at the Oyster Creek Generating Station. The aging effects are managed by inspection of wooden poles every ten years by a qualified inspector.

The team reviewed program bases documents and industry guidance. The inspectors also conducted interviews and performed walkdowns with plant personnel. During the walkdown, one pole (JC 514A L) was noted to be degraded. The applicant was able to show that the condition had been previously analyzed and that plans are in place to adequately reinforce the pole.

For the Wooden Utility Pole Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by the Wooden Utility Pole Program. The applicant provided adequate draft guidance to ensure aging effects will be appropriately managed.

10 Periodic Testing of Containment Spray Nozzles The Containment Spray Nozzle Program is an existing program credited with demonstrating that the drywell and torus spray nozzles are not blocked by debris or corrosion products. Carbon steel piping upstream of the drywell and torus spray nozzles is subject to possible general corrosion that could result in plugging nozzles with rust.

Periodic air tests verify that the drywell and torus spray nozzles are free from plugging and are therefore available to provide the steam quenching functions of the nozzles.

The team conducted interviews and reviewed program bases documents and previous test results. The team noted that the existing program has been effective at identifying and correcting degraded conditions.

For the Periodic Testing of Containment Spray Nozzles Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by the Containment Spray Nozzle Program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Inaccessible Medium-Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements The Inaccessible Medium-Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program is a new program developed for the purpose of aging management credited with managing the moisture related aging effects in medium-voltage cable systems at the Oyster Creek Generating Station. The aging effects are managed by cable testing and periodic inspection of manholes.

The team reviewed program bases documents and industry guidance. The inspectors also conducted interviews and performed walkdowns with plant personnel. The manhole inspection frequency was initially established at the NUREG-1801, Revision 1,"Generic Aging Lessons Learned (GALL) Report, recommended two-year frequency based on Oyster Creeks operating experience that does not indicate a trend or recurrence of cable submergence in manholes. However, NRC inspectors identified, approximately 2 inches of water in the manhole selected by the NRC team for inspection. Consequently, the applicant entered this issue into the corrective action system (CA #IR 469998, #IR 471363) and documented the need to re-evaluate the adequacy of the manhole inspection frequency.

Due to several medium-voltage cable failures in Oyster Creeks operating experience, a medium-voltage cable testing program is currently in place. Because of the limited success of the previous DC step voltage testing method, Oyster Creek has begun implementing a new method of cable testing provided by DTE Energy for most of the medium-voltage cables. NUREG 1801 (XI.E3) specifies the test method should be state-of-the-art at the time the test is performed. Although the new DTE Energy testing method is not yet recognized as an industry standard, it is a form of partial discharge testing (partial discharge testing is one of the recognized standards specifically listed in Enclosure

11 the NUREG-1801), and the applicant expects formal acceptance of the new testing method as an industry standard prior to extended operation.

The applicant has agreed to maintain the current testing frequency limit of six years in LRCR 289 for the first six years, after which the frequency may be re-evaluated and extended up to ten years. This change will provide sufficient time for successful operating experience prior to expanding to the NUREG 1801 recommended ten year frequency.

For the Inaccessible Medium-Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by the Inaccessible Medium-Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Electrical Cables and Connections Not Subject to 10 CFR 50.49 Environmental Qualification Requirements The Electrical Cables and Connections Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program is a new program credited with managing the heat, radiation, and moisture aging effects in non-environmentally qualified electrical cables and connections in Oyster Creek Generating Station. Connections include splices, terminal blocks, connectors, and fuse blocks. The aging effects are managed by periodic inspections.

The team reviewed program bases documents, a draft implementing procedure and industry guidance. The inspectors also conducted interviews and performed walkdowns with plant personnel. Inspections will be done of all accessible cables and connections in adverse localized environments. This aging management program focuses on a representative sample of accessible cables and connections with sampling structured to include key areas of concern. Plant locations containing cables within scope that do not include adverse general or localized conditions may be excluded from inspections based on engineering evaluations.

Because there were several examples of polyvinyl chloride cable insulation bleeding in Oyster Creeks operating experience, the applicant agreed to specifically include polyvinyl chloride cable insulation bleeding as an aging effect to be addressed in this program. Although polyvinyl chloride cable insulation bleeding has not led to any equipment degradation at Oyster Creek, there have been instances cited in NRCs Information Notices 91-20 and 94-78 where polyvinyl chloride insulation bleeding under unfavorable configurations caused hardened plasticizer to degrade equipment. As a consequence of the NRCs review, the applicant entered this issue into their corrective action system (AR 00472707) in order to evaluate the current extent-of-condition of polyvinyl chloride cable insulation bleeding and determine if their original screening of this aging affect should be revised.

Periodic Inspection - Forked River Combustion Turbine The Periodic Inspection - Forked River Combustion Turbine program is a new program credited with addressing the two Forked River Combustion Turbine power plant components in the scope of license renewal that require periodic monitoring of aging Enclosure

15 effects, and are not covered by other aging management programs. In the applicants response to the NRCs requests for additional information, RAI 2.5.1.19-1, dated October 12, 2005 and November 11, 2005, the applicant expanded the single aging management for the Forked River Combustion Turbine to twelve aging management programs. This periodic inspection program is one of twelve programs that monitor the aging effects of the Forked River Combustion Turbine.

The Periodic Inspection - Forked River Combustion Turbine aging management program manages the aging effect of change in material properties, loss of material and reduction of heat transfer for systems, components, and environments. The aging effects are managed by periodic inspections that will be condition monitoring examinations performed at susceptible locations in the systems, intended to assure that existing environmental conditions are not causing material degradation that could result in a loss of system intended functions. These inspections will be performed on a periodicity not to exceed once every 10 years and will coincide with major combustion turbine maintenance inspections.

The two Forked River Combustion Turbines are owned, operated, and maintained by FirstEnergy, under contract to supply station blackout services to Oyster Creek Generating Station. The inspectors reviewed program bases documents, maintenance rule performance data, walkdown reports, and action logs. Applicable portions of the Interconnect and Station Blackout Agreements were reviewed. The inspectors also conducted interviews and performed walkdowns with Oyster Creek Generating Station and FirstEnergy personnel of the Forked River Combustion Turbine facility and portions of its switchyard. The inspectors observed maintenance activities conducted by General Electric for FirstEnergy on Forked River Combustion Turbine #2 during a minor outage.

Though the Forked River Combustion Turbines are operated and maintained by FirstEnergy, Oyster Creek Generating Station assigns a system engineer to monitor their performance via monthly data sets and logs received from the onsite FirstEnergy engineers. Significant events and maintenance on the Forked River Combustion Turbine are logged and evaluated by the Oyster Creek system engineer for further action.

At the time of this inspection, the implementing procedures for this program were not developed. Hence, the aging management program elements have not been negotiated with FirstEnergy to be added into the Station Blackout Agreement. The Office of Nuclear Reactor Regulation accepted AmerGens response to 2.5.1.15-1 and 2.5.1.19-1 and requests for additional information. Based on discussions with applicant personnel and reviews of supporting documents, the inspectors concluded that the applicant has plans to develop adequate guidance and terms for implementation of the Periodic Inspection -

Forked River Combustion Turbine Program. AmerGen will negotiate those terms into the station blackout agreement.

For the Periodic Inspection - Forked River Combustion Turbine Program, the inspectors concluded the applicant had conducted adequate evaluations as well as industry experience and historical reviews to determine aging effects managed by an aging management program. The applicant provided an acceptable plan to implement adequate guidance and terms to ensure aging effects are appropriately managed.

21 Metal Fatigue of Reactor Coolant Pressure Boundary The Metal Fatigue of Reactor Coolant Pressure Boundary Aging Management Program monitors select components in the reactor coolant pressure boundary by tracking and evaluating contributing plant events. The Metal Fatigue of Reactor Coolant Pressure Boundary program monitors operating transients and, by way of a computer program, calculates up-to-date fatigue usage factors.

The design basis metal fatigue analyses for the reactor coolant pressure boundary are considered time limited aging analysis for the purposes of license renewal. The Metal Fatigue of Reactor Coolant Pressure Boundary Program provides an analytical basis for confirming that the number of cycles, established by the analysis of record, will not be exceeded before the end of the period of extended operation. In order to determine cumulative usage factors more accurately, the program will implement FatiguePro fatigue monitoring software. FatiguePro calculates cumulative fatigue using both cycle-based and stress-based monitoring. This provides an analytical basis for confirming that the number of cycles established by the analysis of record will not be exceeded before the end of the period of extended operation.

For the Metal Fatigue of Reactor Coolant Pressure Boundary Aging Management Program, the inspectors reviewed the program including the basis calculations, ongoing monitoring, corrective actions, limiting components, and current cumulative usage factors for the limiting components. The applicant provided adequate guidance to ensure aging effects are appropriately managed.

Isolation Condenser System Review The Oyster Creek license renewal application listed a number of plant systems within the scope of license renewal. From this list the inspectors selected the isolation condenser system for a focused review to determine whether the applicants aging management programs were adequate to effectively manage aging effects related to this component. The following aging management programs are credited for managing aging effects of the isolation condenser system: ASME Section XI In-service Inspection, Subsection IWB, IWC, and IWD; Bolting Integrity; BWR Stress Corrosion Cracking; One Time Inspection; Structures Monitoring Program; and, Water Chemistry.

The inspectors focused on the loss of material aging effect to determine how it would be managed by the identified programs applied specifically to the Isolation Condenser System.

Although the Oyster Creek 10 CFR 50, Appendix K, design basis event analysis, no longer takes credit for the Isolation Condenser it is very important for post-accident heat removal and mitigation of event consequences. It ranks very high on the probabilistic risk worth for this reason. Because of its risk importance the inspectors reviewed the aging management programs given credit for managing the affects of aging in the system.

Enclosure

22 The Isolation Condenser System contains safety-related components relied upon to remain functional during and following design basis events. For example the primary coolant boundary must be maintained through the condenser. Additionally the failure of nonsafety-related structures and components in the Isolation Condenser System could potentially prevent the satisfactory accomplishment of a safety-related function. The isolation condenser also performs functions that support fire protection and station blackout.

AmerGen is committed, in their application documents, to maintaining the water environment of the secondary side because the integrity of the heat exchanger tubes can be affected from both the inside and outside. Additionally, the heat exchanger shell, and therefore, the secondary water environment, is part of the One-Time Aging Management program because it is required to maintain structural integrity during a design basis earthquake to support the heat exchanger tubing and the attached reactor coolant/steam line piping.

The applicant proposed using the ASME Section XI In-service Inspection, Subsections IWB, IWC, and IWD aging management program with the water chemistry aging management program to manage loss of material of the Isolation Condensers. The inspectors reviewed the Oyster Creek in-service inspection program procedure ER-OC-330-1001, ISI Program Plan Fourth Ten-Year Inspection Interval to verify that it was modified to include inspections of the isolation condenser tube side components, eddy current testing of the tubes, and inspection (VT or UT) of the tube sheet and channel head to ensure that degradation is not occurring and the components intended function will be maintained. The inspectors reviewed selected NDE reports of isolation condenser system piping and components, where degradation would result, to verify compliance with ASME Section XI Code.

The inspectors reviewed the UT wall thickness data sheet 96-023-03 from 1R16 refueling outage which documented shell thickness measurements of the B Isolation Condenser. The UT results indicate that the shell thickness was over 0.350 inches in most cases with one reading at 0.312 inches. The vendor drawing 1691-655-20 indicates the shell thickness is 0.375 inches with 0.100 inches corrosion allowance with a minimum of 0.275 inches. Therefore, the B Isolation Condenser meets the original design specifications. The inspectors noted that coating inspections performed by the applicant of the inside shell surface of the B Isolation Condenser during 1R16 in 1996 blistering of the coating was observed in most of the submerged sections. The coating on the inside shell of the isolation condensers is not credited in the aging management programs.

Based on discussions with applicant personnel and reviews of the One-time Aging Management Program basis documents, the inspectors determined the applicant has elected to perform a one-time aging management program inspection of the shell of isolation condenser prior to entering extended plant operations.

b. Observation The inspectors identified an observation related to the monitoring of liquid leakage from the former drywell sand bed region related to the current operating license period. This observation was determined not to be safety significant and has been entered into the applicants ongoing corrective action system.

A current commitment for monitoring the sand bed drains is in a staff Safety Evaluation Report transmitted by letter November 1, 1995. This Safety Evaluation Report requested a commitment to perform inspections 3 months after the discovery of any water leakage. Subsequent correspondence from General Public Utilities Nuclear Corporation the licensee, at the time, clarified the commitment after discussions with the staff. The commitment made and accepted by the staff in a February 15, 1996, letter was to perform an evaluation of the impact of any leakage during power operations and conduct additional inspections of the drywell approximately 3 months after discovery of the water leakage if the evaluation determines that it is warranted.

This commitment was not meant to apply to minor leakage from normal refueling activities.

During the inspection, the NRC team requested a walkdown of the torus room.

AmerGen staff walked down the torus room prior to the NRC team making entry. Water collection jugs, fed by tubing from the former drywell sand bed drains, were emptied prior to the NRCs walkdown, without taking samples of the water in the jugs or recording water levels. The fact that water was present in the jugs meant that leakage had been occurring. The applicant informed the NRC team that the bottles had been improperly emptied without measurement or analysis. Upon further investigation, the applicant could not find documentation that showed prior surveillance of the water drains had been completed. AmerGen staff also could not find documented evidence that strippable coating of the refueling channel had been applied. This strippable coating is used as a measure to limit or prevent water leakage during refueling operations.

The applicant stated that, although there was no formal leakage monitoring in place, there has been no previous reported evidence of leakage from the former sand bed drains. Issue Report #348545 was submitted into the corrective action process when the missed commitment and the improper emptying of the bottles were discovered.

This corrective action will capture the commitment in the applicants computerized scheduling process so that the required actions will be automatically prompted.

Because there was no previously reported leakage, the applicant did not investigate the source of leakage, take corrective actions, evaluate the impact of leakage, or perform additional drywell inspections.

The applicant further stated that a number of actions had been taken to alleviate the previous water leakage problem since discovery of the consequent drywell shell corrosion in the early 1990's. Some of the significant actions consisted of inspections of the reactor cavity wall, remote visual inspection of the trough area below the reactor cavity bellows seal area, and subsequent repair of the trough area and clearing of its drain. Clearing of the trough drain and repair of the trough routed any leakage away from the drywell shell. In addition, AmerGen believes that the strippable coating was Enclosure

24 applied to the reactor cavity walls before the reactor cavity is filled with water as part of refueling activities to minimize the likelihood of leakage into the trough area.

The license renewal application does not take credit for the use of the strippable coating, or the monitoring of the water leakage in managing the aging affects on the liner. As long as the coating of the exterior surface of the former sand bed area is maintained, any amount of water can be present and have no affect on the corrosion rate. The thickness of the cylindrical portion of the liner is managed using ultrasonic testing and this program will capture any changes in corrosion rate due to water in the liner gap. AmerGen has taken corrective actions to ensure, in the future, the drains are monitored, and the strippable coating is applied.

c. Overall Findings The inspection verified that there is an adequate approach to monitor and control the effects of aging so that the intended function(s) of systems, structures, and components, for which an aging management review is required, will be maintained consistent with the current licensing basis during the period of extended operation. The inspection verified documentation, procedures, guidance, and personnel, appropriately supported the license renewal application.

40A6 Meetings, Including Exit The inspectors presented the inspection results to Mr. T. Rausch, Oyster Creek Generating Station Vice President, and other members of the licensees staff in a meeting that was open for public observation on September 13, 2006. The licensee had no objections to the NRC observations. No proprietary information was provided to the inspectors during this inspection. The State of New Jersey, Department of Environmental Protection attended the exit meeting, and made a statement at the meeting concerning the observation associated with the monitoring of liquid leakage from the former drywell sandbed drains. In addition, they stated that a letter concerning this issue was sent to the NRC Region I Regional Administrator dated September 13, 2006. A copy of this letter is available in the NRC ADAMS document management system under ML062630218.
