REPORT DETAILS
OTHER ACTIVITIES (OA)
4OA5 Other Activities Post-Approval Site Inspection for License Renewal
Phase 2 Inspection Activities The team performed the Phase 2 Inspection activities prior to, and within 6 months of the period of extended operation. The period of extended operation is the additional 20 years beyond the original 40-year licensed term. The period of extended operation for Cooper Nuclear Station begins after midnight on January 18, 2014.
The team evaluated whether the licensee:
- (1) completed actions required to comply with the license renewal license condition and commitments;
- (2) implemented the aging management programs that agreed with those approved in the safety evaluation report and described in the updated safety analysis report;
- (3) followed the guidance in NEI 99-04, Guidelines for Managing NRC Commitment Changes, for changing license renewal commitments and followed the guidance in 10 CFR 50.59 when making changes to the license renewal supplement;
- (4) identified, evaluated, and incorporated newly identified structures, systems, and components into their aging management programs; and
- (5) implemented operating experience review and corrective action programs that account for aging effects.
.01 Aging Management Programs with Associated Commitments
a. Inspection Scope
The team evaluated whether the licensee met the commitments and established aging management programs that effectively implemented activities to control the effects of aging. The team compared the commitments and aging management programs to the program descriptions in the updated safety analysis report supplement and in NUREG-1944, Safety Evaluation Report (SER) Related to the License Renewal of Cooper Nuclear Station, and to the Generic Aging Lessons Learned (GALL) Report, Revisions 1 and 2, as appropriate.
The team reviewed supporting documents including implementing procedures, work orders, inspection reports, engineering evaluations, and condition reports; and visually inspected structures, systems, and components, as needed. The team evaluated whether the licensee completed the necessary actions to comply with the license conditions stipulated in the renewed facility operating license. The team interviewed the program owners for each program and other licensee personnel to evaluate whether the licensee completed the necessary actions to meet the commitments specified in the safety evaluation report.
NUREG-1944 and the updated safety analysis report supplement list the aging management programs and associated commitments made during the license renewal application process.
During this inspection, the team reviewed 36 of the 40 commitments and closed 32 commitments. The NRC had previously closed 4 commitments during the Phase 1 inspection documented in NRC Inspection Report 05000298/2012008 (ADAMS ML12342A390). The team did not close Commitments 29, 33, 34, and 35.
The licensee created new Commitment 41 to track resolution of the amount of ferrite contained in the cast austenitic stainless steel main steam and reactor feedwater nozzles. The team reviewed 34 aging management programs.
Specific documents reviewed are listed in the report attachment.
b. Findings and Observations
1. B.1.1 Aboveground Steel Tanks Program and Commitment 1
The Aboveground Steel Tanks Program aging management program managed loss of material from external surfaces of outdoor, aboveground carbon steel tanks. The licensee performed periodic visual inspection of external surfaces and thickness measurement of locations inaccessible for external visual inspection. The licensee monitored Fire Water Storage Tanks A & B and Condensate Storage Tank 1A under this program.
The team interviewed the program owner and reviewed procedures, safety evaluation report, license renewal application, and updated safety analysis report. The team reviewed inspection records from 2007 and 2009 to evaluate the effectiveness of this aging management program, as well as verify that the licensee had established a baseline to evaluate any future degradation. The team determined that the licensee had removed the insulation from the fire water storage tanks and coated the exterior surface with a fiberglass foam insulation to prevent intrusion of moisture and ensure prevention of corrosion.
Commitment 1 specified:
Implement the Aboveground Steel Tanks Program. The thickness measurements will be performed at least once during the first 10 years of the period of extended operation and periodically thereafter. The results of the initial inspection will be used to determine the frequency of subsequent inspections.
The team verified that Procedure 3.13.2, Above Ground Steel Tanks Program, Revision 1, specified that the licensee would perform bottom thickness measurement inspections for all of the tanks within the first 10 years after entering the period of extended operation. The team determined that the licensee had scheduled the inspection of the condensate storage tank for fall 2018 (Refueling Outage 30). Also, the licensee scheduled the inspections for the fire water storage tanks in 2024. The team determined Procedure 3.13.2 specified visual inspections of each of the tanks each operating cycle.
Based on review of the actions implemented related to the Aboveground Steel Tanks Program aging management program, the team concluded the licensee took appropriate actions to protect the tank exteriors and allow for easier inspection. The team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. Further, the team concluded that the licensee met the conditions of Commitment 1 prior to the period of extended operation.
2. B.1.2 Bolting Integrity Program and Commitment 2
The Bolting Integrity Program aging management program managed aging effects caused by loss of material, crack initiation, and loss of preload through periodic inspection of closure and structural bolting for indications of potential problems. The program implemented guidelines on materials selection, strength and hardness properties, installation procedures, lubricants and sealants; corrosion considerations in the selection and installation of pressure-retaining bolting, and enhanced inspection techniques.
The team reviewed the aging management program basis documents, implementing procedures, selected work orders, corrective actions documents, updated safety analysis report and safety evaluation report. The team interviewed the program owner to verify enhancements and program requirements had been met, including that the use of protective lubricants would not cause cracking of bolting. The team verified that personnel were familiar with the requirements of the bolting procedure.
Commitment 2 specified:
Enhance the Bolting Integrity Program to include guidance from EPRI (Electric Power Research Institute) NP-5769, Degradation and Failure of Bolting in Nuclear Power Plants, April 1988 and EPRI TR-104213, Bolted Joint Maintenance &
Applications Guide, December 1995, for material selection and testing, bolting preload control, inservice inspection, plant operation and maintenance, and evaluation of the structural integrity of bolted joints. Enhance the program to clarify that actual yield strength is used in selecting materials for low susceptibility to SCC, to clarify the prohibition on use of lubricants containing MoS2 for bolting at CNS, and to specify that proper gasket compression will be visually verified following assembly.
Enhance the program to include guidance from EPRI NP-5769 and EPRI TR-104213 for replacement of non-Class 1 bolting and disposition of degraded structural bolting.
The team determined that Procedure 7.2.71, Bolting and Torque Program, Revision 38:
- Included guidance related to material selection and testing, bolting preload control, inservice inspection, plant operation and maintenance, and evaluation of the structural integrity of bolted joints;
- Clarified that personnel should use the actual yield strength when selecting materials for low susceptibility to stress corrosion cracking, to prohibit the use of lubricants containing MoS2 for bolting, and to specify that proper gasket compression would be visually verified following assembly; and
- Included guidance for replacement of non-Class 1 bolting and disposition of degraded structural bolting.
Based on review of the actions implemented related to the Bolting Integrity Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded that the licensee met the conditions of Commitment 2 prior to the period of extended operation.
3. B.1.3 Buried Piping and Tanks Inspection Program and Commitments 3, 36, 37, 38, 39,
and 40 The Buried Piping and Tanks Inspection Program aging management program managed the effects of aging on buried piping, tanks, and valves through
- (1) preventive measures to mitigate corrosion and
- (2) inspections to manage the effects of corrosion on the pressure-retaining capability of buried carbon steel and gray cast iron components. If trending within the corrective action program identified susceptible locations, the licensee evaluated areas with a history of corrosion problems to determine the need for additional inspection, alternate coating, or replacement. The team determined that the licensee identified the following systems as in-scope for license renewal: diesel generator fuel oil, standby gas treatment, high pressure coolant injection, service water, condensate makeup, and plant drains.
The team reviewed program documents, implementing procedures, license renewal documents, the updated safety analysis report, the safety evaluation report, plant modifications, and records. The team interviewed the program owner and reviewed excavation results, cathodic protection tests, corrective action documents, soil analysis evaluations, ultrasonic tests of in-scope buried pipes, and coating evaluations for the in-scope buried pipes.
The team determined that the licensee had:
- (1) upgraded and implemented a distributed bed cathodic protection system,
- (2) performed both local and guided wave ultrasonic tests on the excavated buried piping systems,
- (3) determined that they did not have corrosive soil,
- (4) established a buried piping program that risk-ranked all piping on site, and
- (5) included all the requirements of the license renewal safety evaluation report in their buried piping program.
Commitment 3 specified:
Implement the Buried Piping and Tanks Inspection Program.
The team determined that the licensee described this aging management program in Procedure 3.13.1, Buried Piping and Tank Inspection Program Implementation, Revision 3. The licensee included portions of the program in Procedure 3-EN-C-343, Underground Piping and Tanks Inspection and Monitoring Program, Revision 5C0 and Buried Piping and Tanks Program Basis Document, Revision 0. The team verified that the licensee had completed all of their actions required by this program prior to entering the period of extended operation.
Commitment 36 specified:
The Buried Piping and Tanks Inspection Program will include a risk assessment of in-scope buried piping and tanks that includes consideration of the impacts of buried piping or tank leakage and of conditions affecting the risk for corrosion. The piping segments and tanks will be classified as having a high, medium or low impact of leakage based on items such as the safety class, the hazard posed by fluid contained in the piping, and the impact of leakage on plant operation. The corrosion risk will be determined through consideration of items such as piping or tank material, soil resistivity, drainage, the presence of cathodic protection, and the type of coating. During the period of extended operation, examinations of in-scope buried piping and tanks will be performed at a frequency of at least once every 10 years.
Examinations of buried piping and tanks during the period of extended operation will consist of visual inspections as well as non-destructive examination (e.g. ultrasonic and guided wave) to perform an overall assessment of the condition of buried piping and tanks. The examinations will include visual inspection of at least eight feet of excavated piping on at least three high-risk in-scope systems, and will examine a minimum of 2 percent of the total linear feet of high-risk in-scope buried piping during each 10-year period.
The team verified that the licensee documented their initial risk assessment for all buried piping systems, including the in-scope license renewal systems in Report 1000098, Site Specific Risk Report: Cooper Nuclear Station, dated December 22, 2010. The team verified that the risk ranking:
- (1) included consideration of the impacts of buried piping or tank leakage and of conditions affecting the risk for corrosion;
- (2) classified piping segments and tanks as having a high, medium or low impact of leakage based on items such as the safety class, the hazard posed by fluid contained in the piping, and the impact of leakage on plant operation;
- (3) included items such as piping or tank material, soil resistivity, drainage, cathodic protection, and coatings to establish the corrosion risk.
The team verified that the licensee performed a study to determine soil resistivity, as documented in Report 1100302.401, Soil Corrosivity Analysis and Engineering Assessment of Effects on Buried Piping, dated December 4, 2012.
The team verified that Procedure 3.13.1 required:
- (1) examinations of in-scope buried piping and tanks would be performed at least once every 10 years;
- (2) visual inspections as well as non-destructive examination (e.g. ultrasonic and guided wave) to assess the condition of buried piping and tanks;
- (3) examinations of at least eight feet of excavated piping on at least three high-risk in-scope systems; and
- (4) examination of a minimum of 2 percent of the total linear feet of high-risk in-scope buried piping during each 10-year period.
During discussions, the licensee indicated that they would inspect at least eight feet of three of their highest risk-ranked buried piping systems every 10-year period. The team determined this was an appropriate way to evaluate and manage the aging effects on buried piping since they did not have any high-risk in-scope buried pipe systems. The licensee agreed to include this guidance in Procedure 3.13.1 to ensure that at least eight feet of three of the highest in-scope risk-ranked piping systems would be excavated and evaluated. The license initiated LO-2011-00258-084 to track this change.
Commitment 37 specified:
Prior to the period of extended operation, NPPD will inspect buried piping and tanks in six systems. These systems are diesel generator fuel oil (DGFO), standby gas treatment, high pressure coolant injection (HPCI), service water (SW), condensate makeup (CM), and plant drains. Direct or opportunistic visual inspections of excavated piping will be performed for DGFO, standby gas treatment, plant drains, SW, and CM systems. NPPD will use a non-visual examination method for the emergency condensate storage tank supply to HPCI piping due to its lack of ready access for excavation. In addition, non-visual examination methods may be employed for buried piping in other systems where the piping configuration allows for effective assessment via such methods. The total linear feet of piping inspected using all of the methods discussed above will be a minimum of 2 percent of all high-risk in-scope buried piping.
The team reviewed the inspection results for the in-scope systems in Report 1104551.407, Summary of 2013 Direct Examinations at Cooper Nuclear Station, dated October 7, 2013, and Report 1200599.402, ILI Inspection of High Pressure Coolant Injection Suction Line 18 HP-5 at Cooper Nuclear Station, dated December 7, 2012. The team verified that the licensee inspected the diesel generator fuel oil, standby gas treatment, high pressure coolant injection, condensate makeup supply, service water and plant drains prior to entering the period of extended operation. The licensee performed the high pressure coolant injection line inspection with a robot from the interior of the piping. The licensee inspected a minimum of eight feet of piping in each of the systems, performed visual inspections of the exterior of each piping segment excavated, used guided wave technology where excavated, and evaluated then repaired the piping system coatings.
Commitment 38 specified:
Irrespective of risk ranking, NPPD will inspect at least one segment of buried piping in each of three in-scope systems, service water, fire protection, and condensate makeup.
The team verified that the licensee inspected the service water, fire protection and condensate makeup systems. The licensee documented the fire protection system inspection in Inspection Checklist 10-04-2011 and the service water and condensate makeup inspections in Report 1104551.407.
Commitment 39 specified:
NPPD will upgrade the site cathodic protection system prior to the period of extended operation for in-scope piping and buried tanks.
The team verified that the licensee upgraded their cathodic protection system prior to entering the period of extended operation. The team reviewed the modifications for the upgraded components and reviewed the protection provided by the newly installed cathodic protection system. The team determined that the licensee provided sufficient protection for the in-scope buried piping systems. The licensee indicated that they expected to make additional voltage adjustments to their cathodic protection system during the next annual survey.
Commitment 40 specified:
The Buried Piping and Tanks Inspection Program will be revised to ensure that, during the period of extended operation, the cathodic protection system will be maintained and annually tested in accordance with NACE (National Association of Corrosion Engineers) standards RP0285-2002, Corrosion Control of Underground Storage Tank Systems by Cathodic Protection, and SP0169-2007, Control of External Corrosion on Underground or Submerged Metallic Piping Systems, with a minimum system availability of 90 percent. If 90 percent availability is not maintained, the condition will be entered into the corrective action program to evaluate the impact and effect corrective action.
The team determined that the licensee established weekly rectifier channel checks by operations and fire protection personnel. The licensee specified in Procedure 3.13.1 that they would maintain 90 percent availability on a 12-month rolling average and would initiate a condition report whenever 90 percent availability is not maintained. Although Procedure 3.13.1 specified periodic tests of the rectifiers to meet the criteria in NACE SP0169-2007, the team verified that the licensee established a periodic task to test the system annually.
Based on review of the actions implemented related to the Buried Piping and Tanks Inspection Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded that the licensee met the conditions of Commitments 3, 36, 37, 38, 39, and 40 prior to the period of extended operation.
4. B.1.10 Containment Inservice Inspection Program and Commitments 5, 33, 34, and 35
The Containment Inservice Inspection Program aging management program managed loss of material and cracking for the primary containment and its integral attachments.
The program used the ASME Boiler and Pressure Vessel Code,Section XI, 2001 Edition, through the 2003 Addenda. Visual inspections monitored for loss of material from the steel containment shells and their integral attachments; containment hatches and airlocks; moisture barriers; and pressure retaining bolting. The licensee inspected surfaces for evidence of flaking, blistering, peeling, discoloration, and other signs of distress.
The team reviewed the updated safety analysis report, the aging management program evaluation report, procedures, program documents, and the safety evaluation report.
The team interviewed the program owner and reviewed inspection records.
Commitment 5 specified:
Enhance the Containment Inservice Inspection Program to add examination of required accessible areas using a visual examination method and surface areas not accessible on the side requiring augmented examination to be examined using an ultrasonic thickness measurement method in accordance with IWE-2500(b).
Enhance the program to document material loss in a local area exceeding 10 percent of the nominal containment wall thickness or material loss in a local area projected to exceed 10 percent of the nominal containment wall thickness before the next examination in accordance with IWE-3511.3 for volumetric inspections. To ensure the [drywell sand cushion drain] lines are obstruction free, a vacuum test of all eight sand bed drain lines will be performed prior to the period of extended operation.
The team verified that the licensee revised the Fourth 10-Year Interval Containment Inspection Program, Section 3.2.5, to
- (1) require augmented ultrasonic thickness measurements from the accessible portion of the component for an area that was inaccessible and
- (2) incorporate the requirement to conduct ultrasonic testing when it was predicted to exceed or exceeded 10 percent nominal wall thickness for material loss. The team verified that the licensee conducted Procedure SP11-002, Drywell Sand Cushion Drain Vacuum Test, on June 11, 2012, which demonstrated that all eight sand bed lines remained free of obstructions and did not contain any water.
Commitment 33 specified:
NPPD will recoat the wetted portion of the CNS torus within 3 years after entering the period of extended operation.
The team discussed this commitment with the program owner and responsible managers. The team verified that the licensee continued to carry this as a budgeted item for implementation in 2016 during Refueling Outage 29. The licensee indicated that they would evaluate their available options related to managing the effects of aging of the submerged portions of the torus (pressure suppression chamber) following the upcoming inspections. The team determined from discussions with the program owner and from review of inspection reports that the corrosion rate had remained relatively constant between 2-5 mils per year. The licensee attributed this to the inerted atmosphere decreasing the amount of available oxygen for generating corrosion products, the reduced conductivity because of the reduced amount of particulates, and removal of the corrosion products that reduced the ability of particulates to create concentration cells.
Commitment 34 specified:
NPPD will remove sludge and inspect the wetted portion of the torus every refueling outage from now until the torus is recoated.
The team reviewed inspection reports NUC2010117, Refueling Outage RE26 Reactor Torus Filtration and Desludging, IWE Examination, Coating and Corrosion Inspection Coating Repair, Revision 0, and NUC2012108, Refueling Outage RE27 Reactor Torus Filtration and Desludging, IWE Examination, Coating and Corrosion Inspection Coating Repair, Revision 0. The team verified that the licensee removed sludge and corrosion products prior to inspecting the torus during the last two outages. The team determined that the licensee identified no pits that exceeded the reporting threshold in 2011 and identified two pits that exceeded the reporting threshold in 2012. The team determined that the licensee had identified a decreased number of pits exceeding the thresholds since they began desludging and cleaning the torus each outage. The licensee planned the next inspection in the fall 2014. The team verified that the licensee tracked future sludge removal activities with LO 2010-0259-005 and LO 2010-0259-006.
Commitment 35 specified:
NPPD will complete an analysis following each torus inspection that demonstrates that the projected pitting of the torus up to the time that the torus is recoated, will not result in reduction of torus wall thickness below minimum acceptable values.
The licensee performed Calculation NEDC 94-214, Evaluation of Torus Shell Corrosion and the Impact to Structural Integrity of the Torus, Revision 6, following Refueling Outage 26. Calculation NEDC 94-214 utilized actual measurements from Bay 6 and Bay 9 control areas to estimate the representative corrosion rates of the torus. The calculation determined that the torus corroded between 1-2 mils per year since the previous inspection in 2011. To estimate the amount of time available before exceeding any minimum thickness values, the licensee scaled up the corrosion rate by a factor of 2.5 and used 5 mils per year. The licensee further determined that they could have up to 8 mils per year corrosion and still monitor/inspect the torus every 2 years through 2020. Since the calculation used an end point of 2020, the team recommended that the licensee revise the calculation to consider the entire 20-year period of the period of extended operation.
License Condition 2.F specified, The USAR supplement, as revised, describes certain future activities to be completed prior to and/or during the period of extended operation.
The licensee shall complete these activities in accordance with Appendix A of NUREG-1944, Safety Evaluation Report Related to the License Renewal of Cooper Nuclear Station, dated October 2010, as supplemented by letters from the licensee to the NRC dated November 15 and 18, 2010. The licensee shall notify the NRC in writing when implementation of these activities is complete and can be verified by the NRC inspection.
The team determined that the licensee had not updated Calculation NEDC 94-214 following Refueling Outage 27. The team identified the failure to perform Calculation NEDC 94-214, as required by Commitment 35, as a performance deficiency for failure to meet the conditions of License Condition 2.F. Subsequently, the licensee completed Calculation NEDC 94-214, Revision 7, for the data collected during Refueling Outage 27 that demonstrated the corrosion rate remained linear at approximately 2 mils per year. The team screened this performance deficiency using Manual Chapter 0612, Appendix B and concluded it was of minor safety significance. The licensee entered this into their corrective action program as Condition Report 2013-07566. The licensee added clarification to LO-2010-00259 that required them to update the corrosion analysis in Calculation NEDC 94-214 following every refueling outage until the licensee recoated the torus.
By using a conservative corrosion rate of 8 mils per year, the licensee determined that the torus recoat could wait until the 2018 refueling outage. The team verified that the licensee tracked future calculations of corrosion rate with LO 2010-0259-009 and LO 2010-0259-010.
Based on review of the actions implemented related to the Containment Inservice Inspection Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation for those portions of the program related to Commitment 5. The team concluded that the licensee met the conditions of Commitment 5 prior to the period of extended operation.
The team updated the status for Commitments 33, 34, and 35. These commitments could not be closed since the licensee continued to implement the requirements and the commitments had a due date of January 18, 2017. Consequently, these commitments and this portion of the program will be reviewed during a future inspection.
5. B.1.12 Diesel Fuel Monitoring Program and Commitment 6
The Diesel Fuel Monitoring Program aging management program managed the effects of aging caused by loss of material and corrosion. The program used fuel sampling to ensure that the licensee maintained adequate diesel fuel quality to prevent loss of material in fuel systems. The licensee minimized the exposure to fuel oil contaminants such as water and microbiological organisms through periodic sampling and analysis, draining and cleaning of tanks, and verifying new fuel oil quality before placing the fuel into the storage tanks. The licensee performed the sampling and analysis in accordance with technical specifications for fuel oil purity and the guidelines of ASTM Standards D4057, Standard Practice for Manual Sampling of Petroleum and Petroleum Products, and D975, Standard Specification for Diesel Fuel Oils.
The team reviewed the license renewal application, safety evaluation report, updated safety analysis report, reviewed the commitments implementation review document, procedures, work instructions, and interviewed the program owner. The team determined that Engineering Evaluation 11-037, Diesel Fuel Oil Tank Erosion Rate Assessment, Revision 0, demonstrated that the diesel fuel oil tanks erosion rate remained acceptable. The team determined that the minimum wall thicknesses for each tank exceeded the minimum allowable wall thickness and concluded the 20-year inspection interval remained acceptable because of the low rate of erosion. Also, the team confirmed during a walk down of the emergency diesel generators and the diesel fire pump fuel oil tank that the tanks remained in good material condition externally.
Commitment 6 specified:
Enhance the Diesel Fuel Monitoring Program to include the use of ASTM Standard D4057 for sampling of the diesel fire pump fuel oil storage tank. Enhance the Diesel Fuel Monitoring Program to include periodic visual inspections and cleaning of the diesel fuel oil day tanks, the diesel fuel oil storage tanks, and the diesel fire pump fuel oil storage tank. Enhance the program to include periodic multilevel sampling of the diesel fuel oil day tanks and the diesel fire pump fuel oil storage tank and to include periodic visual inspections as well as ultrasonic bottom surface thickness measurement of the diesel fuel oil day tanks, the diesel fuel oil storage tanks, and the diesel fire pump fuel oil storage tank. Enhance the program to provide the acceptance criterion of < 10 mg/I for the determination of particulates in the diesel fire pump fuel oil storage tank. Enhance the program to specify acceptance criterion for UT thickness measurements of the bottom surfaces of the diesel fuel oil day tanks, the diesel fuel oil storage tanks, and the diesel fire pump fuel oil storage tank.
The acceptance criteria for UT measurement of tank bottom thickness for the referenced diesel fuel tanks will be based on component as-built information adjusted for corrosion allowance. If measurements show less than the minimum nominal thickness less corrosion allowance, engineering will evaluate the measured thickness for acceptability under the corrective action program. Evaluation will include consideration of potential future corrosion to ensure that future inspections are scheduled before wall thickness becomes unacceptable.
The team verified that:
- Procedure 6.FP.612, Diesel Fire Pump Fuel Quality Test, Revision 10, incorporated the guidance contained in ASTM Standard D4057 when sampling the diesel fire pump fuel oil storage tank.
- The licensee had initiated preventative maintenance tasks that required inspection and cleaning of the diesel fuel oil storage tanks, diesel fuel oil day tanks, and diesel fire pump fuel oil storage tank. Further, Procedure 7.0.4, Conduct of Maintenance, Revision 37, required maintenance technicians to visually examine internal surfaces for the effects of aging whenever any system or component boundary was breached. Procedure 7.0.4 specified that maintenance technicians complete aging management training (MNT206-00-00).
- Procedure 6.DG.601, Diesel Fuel Oil Day Tank Particulate Contamination Test, Revision 16, required quarterly multilevel sampling of the diesel fuel oil day tanks, and Procedure 6.FP.612, Diesel Fire Pump Fuel Quality Test, Revision 10, required representative bottom sampling of the diesel fire pump fuel oil storage tank.
- Procedure 6.DG.601 incorporated acceptance criteria of less than or equal to 10 mg/L for the diesel fire pump fuel oil storage tank.
- Maintenance Plans 800000033983, Perform Tank Examinations, and 800000008796, Clean Fuel Oil Storage Tanks, established acceptance criteria for ultrasonic testing thickness measurements for bottom surfaces of the diesel fuel oil day tanks, the diesel fuel oil storage tanks, and the diesel fire pump. The team confirmed that the licensee established the acceptance criteria based on the as-built wall thicknesses adjusted for a corrosion allowance.
Procedure 7.0.4 directed that personnel implement corrective actions if measurements show less than the minimum nominal thickness, less the corrosion allowance, for engineering to evaluate the measured thickness for acceptability under the corrective action program. The evaluation addressed potential future corrosion to ensure that future inspections were scheduled before wall thickness becomes unacceptable.
Based on review of the actions implemented related to the Diesel Fuel Monitoring Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded that the licensee met the conditions of Commitment 6 prior to the period of extended operation.
6. B.1.14 External Surfaces Monitoring Program and Commitment 7
The External Surfaces Monitoring Program aging management program monitored for loss of material from external surfaces of systems and components.

- (1) collection of data following reactor pressure vessel operational transients,
- (2) performed a periodic review of operational transients for trending the effect on fatigue usage as noted in the updated safety analysis for the reactor pressure vessel, and
- (3) tracks operational transients for the effect on fatigue usage for the Torus.
Commitment 8 specified:
Consideration of the effect of the reactor water environment will be accomplished through implementation of one or more of the following options for the reactor vessel shell and lower head, feedwater nozzles, core spray nozzles and RHR pipe transition.
1) Update the fatigue usage calculations using refined fatigue analyses to determine valid CUFs (cumulative usage factors) less than 1.0 when accounting for the effects of reactor water environment. This includes applying the appropriate Fen factors to valid CUFs determined using the NRC-approved version of the ASME code or the NRC-approved alternative (e.g., NRC-approved code case). NPPD will use NUREG/CR-6909 when determining the effects of the reactor coolant environment on the fatigue life of Alloy 600 components.
2) Repair or replace the affected locations before exceeding an environmentally adjusted CUF of 1.0.
The CNS Fatigue Monitoring Program will be enhanced to require the recording of each transient associated with the actuation of a safety/relief valve.
In the NRC Inspection Report 05000298/2012008, dated December 6, 2012 (ML12342A390), the inspectors determined that Procedure 3.20, Revision 18, did not incorporate environmental factors and implement the methodology described in Engineering Evaluation 10-023, Reactor Pressure Boundary Components Fatigue Management Plan.

Enhance the program to provide wall thickness evaluations of fire protection piping on system components using non-intrusive techniques (e.g.,
volumetric testing) to identify evidence of loss of material due to corrosion. These inspections will be performed before the end of the current operating term and at intervals thereafter during the period of extended operation. Results of the initial evaluations will be used to determine the appropriate inspection interval to ensure aging effects are identified prior to loss of intended function. Enhance the program to add that a sample of sprinkler heads required for 10 CFR 50.48 will be tested or replaced using guidance of NFPA-25 (2002 edition), Section 5.3.1.1.1, before the end of the 50-year sprinkler head service life and at 10-year intervals thereafter during the period of extended operation.
The team verified that:
- Procedure 6.FP.603, Fire Hose Station Annual Examination, Revision 10, required inspecting hose reels for corrosion and specified no unacceptable corrosion allowed. The licensee established separate maintenance plans to inspect the hose reels for accessible areas and high radiation areas.
- Procedure 6.FP.302, Automatic Deluge and Pre-Action Systems Testing, Revision 24, required inspecting for corrosion when opening deluge valves and specified no unacceptable corrosion allowed. The licensee identified no corrosion when they replaced the deluge valves around transformers in 2012.
- Repetitive Task 800000041971 required ultrasonic testing of fire protection piping to determine wall thickness of the piping. The licensee measured the wall thickness in four pipe lines (i.e., 2.5-, 3-, 4-, and 12-inch). The licensee concluded that the lines had expected service lives that exceed the period of extended operation.
- The licensee elected to replace rather than perform sample testing of their sprinkler heads. The licensee identified they would replace 976 sprinkler heads in eleven fire water lines beginning in 2023 to prevent exceeding their 50-year service life. The licensee created maintenance plans for each line and highlighted the lines on fire protection drawings.
The team verified that the licensee had trained maintenance personnel to recognize corrosion and other forms of age-related degradation during visual inspections.
Procedure 7.0.4 required maintenance personnel to initiate corrective action documents if they identified aging effects such as loss of material or corrosion and required visual examination of internal surfaces for the effects of aging whenever they breached any system or component boundary.

The team verified the program owner implemented the elements of NSAC-202L-R2 and followed the EPRI guidelines for predicting, detecting, and monitoring flow-accelerated corrosion in plant piping and other components by conducting analysis to determine critical locations, performing baseline inspections, and repairing or replacing components as necessary. The team verified that Procedure 3.10, Flow Accelerated Corroston (FAC) and Microbiologically Influenced Corrosion (MlC) Program Implementation, Revision 13, stipulated training and qualification requirements for non-licensee personnel if they performed activities required by the flow-accelerated corrosion program.
Based on review of the actions implemented related to the Flow-Accelerated Corrosion Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 11 prior to the period of extended operation.
11. B.1.20 Inservice Inspection - IWF Program and Commitments 12 and 30 The Inservice Inspection - IWF Program aging management program managed loss of material for ASME Class 1, 2, 3 and MC piping, component supports, bolting, and base plates. Visual inspections looked for evidence of corrosion; deformation; misalignment; improper clearances; improper spring settings; damage to close tolerance machined or sliding surfaces; and missing, detached, or loosened support items that might compromise support function or load capacity.
The team reviewed license renewal documents, program documents, implementing procedures, updated safety analysis report, and safety evaluation report. From interviews with the program owner, the team determined that the licensee had established a program as described in the NRC safety evaluation report and the updated safety analysis report supplement.
Commitment 12 specified:
Enhance the Inservice Inspection - IWF Program to include Class MC piping and component supports. Enhance the program to clarify that the successive inspection requirements of IWF-2420 and the additional examination requirements of IWF-2430 will be applied.
The team determined that the licensee added an additional 128 IWF supports within the scope of license renewal. The licensee grouped the components based on similar function and conditions as allowed by Table IWF-2500-1, Examination Categories, Note 3. The team confirmed that the licensee classified the components into six groups.
The licensee selected the following components for examination in the 5th and 6th inservice inspection intervals: B7-VH-S6, B12-DCPRB-S28, SC-EQT-S0, SC-SAD-S1, B12-DCPR-S28, and NRV24-S5. The licensee scheduled Supports B12-DCPRB-S28 and B12-DCPR-S28 for inspection in the 4th interval that concludes during Refueling Outage 28 in 2014.
Commitment 30 specified:
NPPD will implement the plant modifications designed to correct the main steam line support discrepancies noted in RAI B.1.20-1 prior to the period of extended operation.
The team verified that Calculation NEDC-92-143, Main Steam Supply Piping MSIV Leakage Pathway Analysis Configured with Viscous, Revision 0, provided appropriate evaluations and modification recommendations for the main steam line supports. During the Phase 1 inspection the team had confirmed the installation of the new supports. The licensee planned to perform a confirmatory review to verify the effectiveness of the modification during the upcoming outage.
The team reviewed the vendor report recommending those modifications and the design change package used for its implementation. The modifications added rigid bracing to secure the pipe to adjacent structures proved effective in eliminating lateral movement in the pipe, as recorded by cameras and observed by program owner periodically.
Additionally, the licensee installed supports with viscous fluids to help absorb the waterhammer being experienced.
Based on review of the actions implemented related to the Inservice Inspection - IWF Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 12 and Commitment 30 prior to the period of extended operation.
12. B.1.21 Masonry Wall Program and Commitment 13 The Masonry Wall Program aging management program ensured through visual inspections that the evaluation basis established for each in-scope masonry wall remained valid through the period of extended operation. The program included masonry walls required by 10 CFR 50.48, radiation shielding masonry walls, and masonry walls with the potential to affect safety-related components.
The team reviewed license renewal documents, implementing procedures, program documents, safety evaluation report, and updated safety analysis report. The team interviewed the program owner and performed general area walk downs of several masonry wall structures. The licensee included this aging management program in their maintenance rule structures monitoring program and used the same implementing procedures.
During a general area walk down, the team identified several cracks along grout lines in the maintenance shop masonry block walls. The licensee demonstrated that they had identified these cracks and concluded they posed no structural concern. The team verified that the licensee had taken photographs and provided a narrative description in the plant records. During review of this program area, the team identified several issues that reflected some vulnerability related to retrievable documentation. Specifically, the team:
- Identified the presence of a crack on the south end of the turbine building. The licensee identified they had not documented this crack in their structures monitoring program and initiated Condition Report 2013-07465
- Determined the licensee could not retrieve the structures monitoring program reports for the turbine building from 2007. In addition, the licensee had not issued the structures monitoring report for the turbine building inspections performed in 2012. The licensee initiated Condition Report 2013-07476 to document these deficiencies
- Determined the licensee could not retrieve the masonry wall monitoring reports for the turbine building from 2002. The licensee initiated Condition Report 2013-07333 The team determined that the licensee had not consistently documented nor could they easily retrieve structural deficiencies identified between the formal Structures Monitoring Program scheduled inspections. The licensee documented this concern in Condition Report 2013-07304 and initiated a task to modify their structures monitoring program to formalize their documentation and record retrieval process. The program owner described that the procedure change would require engineers performing inspections and/or documenting deficiencies to update the network drive, plant records, and inspection binders between 5-year inspections. The team determined that the licensee continued to refine their method for tracking and trending anomalies within the structures monitoring program to ensure periodic inspections of spaces include items that arise between inspection frequencies. The team concluded these actions were appropriate.
Commitment 13 specified:
Enhance the Masonry Wall Program to clarify that the control house - 161kV switchyard is included in the program. Enhance the program to clarify that structures with conditions classified as acceptable with deficiencies or unacceptable shall be entered into the Corrective Action Program.
The team verified that Procedure 3-EN-DC-150, Condition Monitoring of Maintenance Rule Structures, Revision 2C1, listed the 161kV switchyard control house as a structure that required monitoring and specified that structures with conditions classified as acceptable with deficiencies or unacceptable shall be entered into the corrective action program. The team determined that the procedure included attachments to assist with specific items to inspect and required personnel to document discrepancies.
Based on review of the actions implemented related to the Masonry Wall Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 13 prior to the period of extended operation.
13. B.1.22 Metal-Enclosed Bus Inspection Program and Commitment 14 The Metal-Enclosed Bus Inspection Program aging management program managed the effects of aging effects associated with loosening of bolted bus bar connections and reduced insulation and insulator resistance on non-segregated bus ducts. Specifically, the program ensured the intended function of the buses were not challenged by circuit failures caused by
- (1) loose bolted connections,
- (2) degraded insulation and insulators,
- (3) degraded exterior enclosures both metallic and non-metallic portions (expansion boots and gaskets), and
- (4) degraded interior portions both metallic and non-metallic portions. The licensee established a periodic program to inspect and test activities every 10 years with the first inspection completed prior to the period of extended operation.
The licensee included the following bus ducts in this program:
- Start-Up Station Service Transformer to non-Safety Switchgear Buses 1A & 1B (start-up station service transformer metal-enclosed bus)
- Emergency Station Service Transformer to Switchgear Buses 1F & 1G (emergency station service transformer metal-enclosed bus)
The team reviewed license renewal program basis documents, aging management review documents, procedures, updated safety analysis report, and safety evaluation report. The team interviewed the program owner, reviewed completed work documents related to the inspection of the bus ducts, and reviewed corrective action documents.
Commitment 14 specified:
Implement the Metal-Enclosed Bus Inspection Program.
The team verified that Procedure 7.3.41, Examination and Meggering of Non-Segregated Buses and Associated Equipment, Revision 9, required visual inspections and circuit resistance tests for the start-up and emergency station service transformer metal-enclosed buses prior to the period of extended operation and every 10 years thereafter. The team verified that the digital low resistance ohmmeter test included the bus and all of its respective bolted connections. The team determined that the procedure required personnel to visually inspect:
- (1) hardware and insulation for cracks, corrosion, foreign debris, excessive dust buildup, and evidence of water intrusion;
- (2) insulation for signs of embrittlement, cracking, melting, swelling, or discoloration, which may indicate overheating or aging degradation;
- (3) internal bus supports for structural integrity and signs of cracks; and
- (4) externally including the metal bus enclosure, expansion boots and gaskets.
From review of the completed inspections, the team determined that the licensee confirmed connections had low resistance and identified and corrected any noted deficiencies.
Based on review of the actions implemented related to the Metal-Enclosed Bus Inspection Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 14 prior to the period of extended operation.
14. B.1.23 Neutron Absorber Monitoring Program and Commitment 31 The Neutron Absorber Monitoring Program aging management program managed loss of material from Boral neutron absorption panels in the spent fuel racks. The program relied on representative coupon samples mounted in surveillance assemblies located in the spent fuel pool to monitor performance of the absorber material without disrupting the integrity of the spent fuel racks.
The team reviewed the license renewal application, safety evaluation report, and updated safety analysis report, reviewed the commitments implementation review document, procedures, and work instructions. The team interviewed the program owner and reviewed the most recent coupon sample results.
Commitment 31 specified:
To verify there is no loss of neutron absorbing capacity of the Boral material, NPPD will supplement the Neutron Absorber Monitoring Program to include neutron attenuation testing of representative sample coupons. Acceptance criteria will be that measured or analyzed neutron-absorber capacity required to ensure the 5 percent subcriticality margin for the spent fuel pool is maintained assuming neutron absorber degradation is the only mechanism. Results not meeting the acceptance criteria will be entered into the CNS Corrective Action Program for disposition. One test will be performed prior to the period of extended operation, with another confirmatory test performed within the first 10 years of the period of extended operation.
The team determined that the neutron attenuation testing of the sample coupons demonstrated no degradation in the neutron absorbing capacity of the Boral material.
Further, the licensee demonstrated that they would maintain the 5 percent subcriticality margin. The team verified that the licensee scheduled the next neutron attenuation test performance for Refueling Outage 29 in 2016. The team verified Procedure 10.20, Boral Coupon Sampling, Revision 16, directed initiating a corrective action document if the test results demonstrate that Boral did not maintain the 5 percent shutdown margin.
From review of teleconference notes and discussions with experts in the Office of Nuclear Reactor Regulation, the team verified that the licensee only had to perform one additional test within the period of extended operation.
Based on review of the actions implemented related to the Neutron Absorber Monitoring Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 31 prior to the period of extended operation.
15. B.1.24 Non-Environmentally Qualified Bolted Cable Connection Program and Commitment 15 The Non-Environmentally Qualified Bolted Cable Connections Program aging management program ensured that the intended functions of in-scope power cable circuits (low and medium voltage) in their operating environments would remain tightly connected through the period of extended operation. The program assessed whether loosening of bolted connections because of thermal cycling, ohmic heating, electrical transients, vibration, chemical contamination, corrosion, and oxidation had occurred prior to the period of extended operation.
The team reviewed license renewal program basis documents, implementing procedures, maintenance plans, updated safety analysis report, and safety evaluation report. The team interviewed the program owner, completed work documents, and corrective action documents.
Commitment 15 specified:
Implement the Non-Environmentally Qualified Bolted Cable Connections Program.
The team verified that the licensee based their selection on the service application, circuit loading, and location. The licensee selected the samples for inspection based upon in-scope circuits with voltage less than 35kV, non-environmentally qualified, and outside of an active electrical assembly (e.g., motor-operated valve, motor control center, et cetera). Using their criteria, the licensee identified the following three in-scope bolted-splice connections:
- Cable MZA-41 - 480V E-Bay Traveling Water Screen Motor, Starter Rack ZA;
- Cable MDG1-83 - 480V Radwaste Sump Pump Z1 Motor feeder;
- Cable OS30 - 12.5kV Fire Pump E Motor feeder on 12.5kV Disconnect 20-D.
The licensee thermo-graphically scanned Connections MZA-41 and MDG1-83 and determined the connections had not degraded because the connections had no appreciable temperature difference or abnormally high temperature rise. The licensee determined the Cable OS30 bolted connections measured less than 100 micro-ohms with a digital low resistance ohmmeter that demonstrated aging stressors (heat, humidity, and vibration) had not caused loose or high resistance bolted cable connections.
Because of the limited number of in-scope connections, the licensee elected to review additional test and inspection results that would have provided an indication of the condition of bolted connections in large power circuits (less than 35kV) that could have been affected by adverse environments (high heat, high humidity and vibration). The licensee programs that periodically test circuits and provide information on bolted connections included thermography and motor circuit evaluation (megger and phase load imbalance) programs. The licensee reviewed inspection results for the previous 4 years. The thermography program results included 239 low voltage connections and 108 Medium voltage connections, and the motor circuit evaluation results included 165 low voltage and 9 medium voltage connections. The licensee identified no issues from review of the test results. The team independently assessed the evaluation, confirmed that the licensee took appropriate corrective actions for identified deficiencies, and confirmed no issues resulted from loose connections.
Based on review of the actions implemented related to the Non-Environmentally Qualified Bolted Cable Connection Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 15 prior to the period of extended operation.
16. B.1.25 Non-Environmentally Qualified Inaccessible Medium-Voltage Cables Program and Commitment 16 The Non-Environmentally Qualified Inaccessible Medium-Voltage Cable Program aging management program included periodic inspections for water collection in underground cable manholes and periodic testing of cables to detect degraded cable insulation.
The team reviewed license renewal program basis documents, aging management review documents, plant procedures, program documents, photographs of the manholes, updated safety analysis report, and safety evaluation report. The team interviewed the program owner, walked down selected cable manholes, reviewed relevant corrective action documents, and reviewed completed tests and maintenance activities.
Commitment 16 specified:
Implement the Non-Environmentally Qualified Inaccessible Inaccessible Medium-Voltage Cable Program. Inspections for water accumulation in manholes containing in-scope inaccessible low-voltage and medium-voltage power cables will be performed at least once every 2 years. In-scope inaccessible low-voltage power cables (cables with operating voltage from 480 V to 2 kV) that are subject to aging management review are included in this program. The in-scope inaccessible low-voltage power cables will be tested for degradation of the cable insulation prior to the period of extended operation and at least once every 10 years thereafter. A proven, commercially available test will be used for detecting deterioration due to wetting of the insulation system for all in-scope inaccessible low-voltage power cables (480 V to 2 kV). Condition-based inspections of [the manhole not dewatered by a sump pump] will be performed based on: a) potentially high water table conditions, as indicated by high river level, and b) after periods of heavy rain.
The team verified that Procedure 3.47.24, Non-EQ Inaccessible Power Cables Program, Revision 2, specified:
- Inspect for water accumulation in manholes containing in-scope inaccessible low-voltage (480 Vac to 2kV) and medium-voltage power cables at least once every 2 years.
- Test in-scope cables for degradation of the cable insulation prior to the period of extended operation and at least once every 10 years thereafter with a proven, commercially available test capable of detecting deterioration resulting from wetting of the insulation.
- Inspect the manhole without a sump pump based upon the installed high water level annunciation.
In order to meet the condition-based inspection for the manhole not dewatered by a sump pump, the licensee installed float switches that annunciated in the control room to alert operators of accumulation of water in the manholes. The team determined the alarm system provided a reliable method to ensure the cables would remain dry or ensure they were wetted for only a short period of time. The team determined that the licensee revised their commitment using their commitment change process and revised their updated safety analysis report in accordance with their 10 CFR 50.59 program.
The team determined that the manholes with installed sump pumps used a float switch inside the sump to activate the sump pump and had an additional float switch set at a higher water level that alerted operators that the water in the manhole had reached an elevation above where the sump pump should have removed the water. The team verified that the licensee established inspections every 2 years in the manholes with sump pumps and established inspections quarterly in manholes without sump pumps to monitor for aging effects. The licensee established plans to test the float switches annually. The licensee planned to test in-scope cables every 10 years to determine the condition of the conductor insulation.
During walk down of the newly installed float switches and review of the float testing procedures, the team determined that the procedure tested actuation of the switch without verifying the float would lift on high water level. The licensee installed the float switches in December 2012 and tested them in March 2013; therefore, the licensee would not conduct the next test until March 2014. Following questions by the team, the licensee verified that the manufacturer tested the stainless steel float for buoyancy at the factory. The licensee initiated actions to test the floats every 2 cycles and initiated a corrective maintenance work order to test the float.
The team identified the failure to verify proper operation of the float as a performance deficiency for inadequate post modification testing. The team screened this performance deficiency using Manual Chapter 0612, Appendix B, and concluded it was of minor significance. The licensee entered this into their corrective action program as Condition Report 2013-07532.
While reviewing photos of the various manholes, the team determined the conduit sealing material had degraded and water had seeped from the conduits, which could have exposed the cable in these conduits to moisture based on rust deposited on the walls of the manholes. The team questioned whether the cables in the conduits between manholes had water trapped because of low spots in the conduit. The team determined that the conduit drawings showed sloped conduits with short runs between manholes. The licensee documented the degraded sealing material in Condition Report 2013-07564 to evaluate the best approach to address the issue. The team verified that the licensee routinely tested the affected cables that demonstrated the cables remained in good condition.
Based on review of the actions implemented related to the Non-Environmentally Qualified Inaccessible Medium-Voltage Cables Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded licensee met the conditions of Commitment 16 prior to the period of extended operation.
17. B.1.26 Non-Environmentally Qualified Instrumentation Circuits Test Review Program and Commitment 17 The Non-Environmentally Qualified Instrumentation Circuits Test Review Program aging management program managed the effects of aging of instrument circuit cables through monitoring of completed test records. This aging management program assured that the intended functions of sensitive, high-voltage, low-signal cables exposed to adverse localized equipment environments caused by heat, radiation and moisture were maintained consistent with the current licensing basis through the period of extended operation. The program included the following grouping of systems: main steam line radiation monitors, reactor building ventilation exhaust monitors, intermediate range monitors, and local power range monitors. The team verified that the licensee completed tests prior to entering the period of extended operation and scheduled test reviews once every 10 years.
The team reviewed license renewal program basis documents, aging management review documents, plant procedures, program documents, updated safety analysis report, and safety evaluation report. The team interviewed the program owner, reviewed relevant corrective action documents, reviewed completed tests and completed maintenance activities.
Commitment 17 specified:
Implement the Non-Environmentally Qualified Instrumentation Circuits Test Review Program.
The team determined that Procedure 3.47.26, Non-EQ Sensitive Instrumentation Circuits Test Review Program, Revision 0, established the aging management program and required personnel to evaluate the test results of the 12 test procedures used to test and calibrate the equipment associated with the in-scope systems. The licensee evaluated whether collective test results and site cable history for these systems indicated cable insulation failures not adequately corrected or resolved through the corrective action program.
The team independently assessed the licensee evaluation of the in-scope test results from 2000-2009. The licensee tested the local power range monitor cables inside containment for the first time in 2011. The team determined that the licensee had confirmed that the cables had not experienced any age-related degradation.
Based on review of the actions implemented related to the Non-Environmentally Qualified Instrumentation Circuits Test Review aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 17 prior to the period of extended operation.
18. B.1.27 Non-Environmentally Qualified Insulated Cables and Connections Program and Commitment 18 The Non-Environmentally Qualified Insulated Cables and Connections Program aging management program managed the aging effects of cables and connections exposed to adverse localized environments caused by heat, radiation and moisture. The program specified periodic visual inspection to confirm the absence of adverse insulated cable and connections aging effects such as embrittlement, discoloration, cracking, or surface contamination at least once every 10 years.
Commitment 18 specified:
Implement the Non-Environmentally Qualified Insulated Cables and Connections Program.
The team verified that Procedure 3.47.27, Non-EQ Insulated Cables And Connections Aging Management Program, Revision 0, provided the guidance to implement the program. The licensee inspected all areas of the plant where adverse localized environments existed rather than determine representative samples. The license divided the inspection areas into two distinct groups: areas walked down during normal plant operation and areas walked down during plant outages. The areas walked down during normal plant operation had the advantage of using thermography to evaluate suspected adverse localized environments and configurations for high temperature exposures to nearby insulated cables and connections. The licensee used visual inspections of accessible insulated cables and connections during outages.
In addition, the licensee specified the following criteria when selecting the cables for inspection:
- (1) easily accessible (i.e. no underground ducts or small chases, no ladders or scaffolds required, safe personnel environment, etc.),
- (2) contain in-scope non-environmentally qualified insulated cables and connections, and
- (3) cables and connections not under another aging management program.
The team determined that the licensee initiated seven condition reports during the inspections performed during normal plant operation. The licensee addressed each of the identified deficiencies and determined that the deficiencies did not result from any unanalyzed adverse localized environments. The licensee initiated corrective actions to replace and reroute cabling that had experienced accelerated aging (discoloration, chalking) in the heater bay area. The team confirmed that the licensee incorporated the guidance in EPRI Report TR-109619, Guideline for Management of Adverse Localized Environments.
Based on review of the actions implemented related to Non-Environmentally Qualified Insulated Cables and Connections Program aging management program, the team determined the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 18 prior to the period of extended operation.
19. B.1.28 Oil Analysis Program and Commitment 19 The Oil Analysis Program aging management program managed aging effects caused by loss of material, cracking, or fouling. The licensee monitored the oil systems through sampling and analysis of lubricating oil for detrimental contaminants, water, and particulates.
The team reviewed procedures, program documents, license renewal documents, the updated safety analysis report and the safety evaluation report. The team interviewed the program owner and reviewed work records associated with the oil analysis program to confirm that the licensee implemented the commitments. The team verified that in-scope systems had experienced no degradation because of contaminated oil and that the licensee had identified no evidence of abnormal wear rates for the in-scope components.
Commitment 19 specified:
Enhance the Oil Analysis Program to include viscosity, neutralization number, and flash point determination of oil samples from components that do not have regular oil changes, along with analytical ferrography and elemental analysis for the identification of wear particles. Enhance the program to include screening for particulate and water content for oil replaced periodically. Enhance the program to formalize preliminary oil screening for water and particulates and laboratory analyses, including defined acceptance criteria for all components included in the scope of the program. The program will specify corrective actions in the event acceptance criteria are not met.
The team verified that Procedure 7.0.14.2, Lubrication/Oil Analysis Program, Revision 8,
- (1) sampled for viscosity and neutralization number and conducted analytical ferrography and elemental analysis for components that did not have regular oil changes;
- (2) screened for particulates and water content for components with periodically replaced oil;
- (3) formalized preliminary oil screening for water and particulates and laboratory analyses, including defined acceptance criteria for all components included in the scope of the program; and
- (4) required personnel to initiate a corrective action document whenever a test failed to meet acceptance criteria. The inspectors verified the licensee established their acceptance criteria in accordance with industry standards.
The team determined that the program did not mention conducting a flash point determination as specified in the safety evaluation report. Subsequently, the team determined that the licensee revised their commitment using their commitment change process and revised their updated safety analysis report in accordance with their 10 CFR 50.59 program. The team agreed with the change since the licensee adopted the guidance in the GALL Report, Revision 2.
Based on review of the actions implemented related to the Oil Analysis Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 19 prior to the period of extended operation.
20. B.1.29 One-Time Inspection Program and Commitment 20 The One-Time Inspection Program aging management program verified the effectiveness of the Oil Analysis, Lubricating Oil, and Water Chemistry aging management programs. Specifically, the licensee reviewed the internals of a sample of mechanical components to assess whether significant aging effects had occurred. The licensee performed visual one-time inspections to address concerns related to long incubation periods for certain aging effects on structures, systems, and components.
Commitment 20 specified:
Implement the One-time Inspection Program.
The team reviewed the one-time inspection procedure, license renewal documents, safety evaluation report, updated safety analysis report, corrective action documents, and calculations. The team interviewed the program owner and reviewed a sample of mechanical one-time inspection visual inspection records. The team verified that the licensee
- (1) selected samples for each material-environment combination with consideration of operating experience,
- (2) identified appropriate inspection locations and examination techniques,
- (3) established appropriate acceptance criteria, and
- (4) assessed the component condition to determine if follow-up inspections would be required. The team determined that the licensee had demonstrated that they had no components that showed the effects of aging, which indicated the Water Chemistry, Oil Analysis, and Lubricating Oil aging management programs had effectively limited any aging effects.
The licensee documented in Calculation 13-012, Flaw Tolerance Evaluation for Reactor Recirculation Flow Element, Revision 0, that they did not have to inspect their main steam and reactor recirculation nozzles as part of the one-time program since the calculation demonstrated that the nozzles were not susceptible to aging effects. The team determined that one of the six criteria reviewed included the amount of ferrite in the cast austenitic stainless steel main steam and reactor recirculation flow elements. The team determined that the amount of ferrite discussed in Calculation 13-012 had a similar basis as the cast austenitic stainless steel components discussed in the Boiling Water Reactor Vessel and Internals Project (BWRVIP)-234, Thermal Aging and Neutron Embrittlement Evaluation of Cast Austenitic Stainless Steels, dated December 2009, (discussed in Section 26). As described in Section 26, NRC continued to question the basis used by industry to determine the amount of ferrite and whether cast austenitic stainless steel components needed to be managed for aging effects.
Because of the uncertainty related to ferrite in cast austenitic stainless steel components, the team determined that the licensee had inappropriately excluded these flow nozzles from being visually or volumetrically examined. The licensee generated a new commitment in Letter NLS2013100, New License Renewal Commitment, dated November 26, 2013. Commitment 41 specified:
NPPD will confirm that the reactor recirculation and main steam line flow restrictor CASS materials are either:
- (a) not greater than 25 percent ferrite, (b)will perform a flaw tolerance evaluation, or
- (c) will perform a qualified visual or volumetric examination. This will be completed within 3 years after the period of extended operation.
Because the licensee had not entered the period of extended operation, the licensee revised the due date for this commitment to January 18, 2017, which matched the dates for the other commitments. The licensee further indicated that they would implement the appropriate corrective actions if they were determined to exceed 25 percent ferrite in their cast austenitic stainless steel components. The team considered this an appropriate corrective action.
Based on review of the actions implemented related to the One-Time Inspection Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 20 prior to the period of extended operation with one exception. The team determined that the licensee took appropriate action to track resolution of the amount of ferrite in cast austenitic stainless steel components to determine the most appropriate action related to their main steam line and reactor recirculation flow elements as Commitment 41.
21. B.1.30 One-Time Inspection - Small-Bore Piping Program and Commitments 21 and 32 The One-Time Inspection - Small-Bore Piping Program aging management program managed the effects of cracking through the use of volumetric examinations on American Society of Mechanical Engineers (ASME) Code Class 1 piping less than 4 inches nominal pipe size (small bore), which included pipe, fittings, and branch connections. The licensee selected their sample based on susceptibility, inspectability, dose considerations, operating experience, and limiting locations of the total population of ASME Class 1 small bore piping locations.
The team reviewed procedures, program documents, license renewal documents, safety evaluation report and updated safety analysis report. The team reviewed selected inspection records and interviewed the program owner. The team verified that the licensee took an appropriate sample population and included small bore pipe inspections in their inservice inspection program.
Commitment 21 specified:
Implement the One-time Inspection Small-Bore Piping Program.
The team determined that Engineering Report CNS-RPT-13-LRIMR-06, One Time Inspection - Small Bore Piping Program Report, Revision 0, summarized the results of licensee actions related to implementing this aging management program.
The team verified that the licensee tracked future changes to the 5th and 6th 10-year Inservice Inspection Intervals with LO 2013-05190-003 and LO 2013-05190-004, respectively. The team determined that the licensee planned to perform volumetric examinations on Socket Welds SLC-BJ-8, SLC-BJ-9, and RVD-BJ-10 during each of the subsequent 10-year inspection intervals Commitment 32 specified:
During the period of extended operation, NPPD will perform periodic volumetric examinations of Class 1 socket weld connections. Three Class 1 socket welds will receive volumetric examination during each 10 year ISI interval. The examination method will be a volumetric examination of the base metal 1/2-inch beyond the toe of the socket fillet weld which allows for the use of qualified ultrasonic examination techniques as close as possible to the fillet weld. The volumetric examinations will be performed by certified examiners following guidelines set forth in ASME Section V, Article 4 consistent with the guidelines for examination volume of 1/2-inch beyond the toe of the weld as established in MRP-146, Materials Reliability Program: Management of Thermal Fatigue in Normally Stagnant Non-Isolable Reactor Coolant System Branch Lines.
The team verified that the licensee had documented inspection results related to ultrasonic examinations of the Class-1 Small Bore Pipe Socket Welds SLC-BJ-8, SLC-BJ-9, and RVD-BJ-10, and Small Bore Pipe Welds RVD-BJ-17, RVD-BJ-18, RSA-BJ-7x, RSA-BJ-8x, RSA-BJ-9, and RSA-BJ-10. The team verified that the licensee performed the volumetric examinations as specified in ASME Section V, Article 4. The team determined that Procedure 3.28.5.UT.SOC, Socket Weld Ultrasonic Phased Array Weld Examination, Revision 0, required personnel performing the examinations be certified to Ultrasonic Testing Level II or III and the examinations be initiated as close to the fillet weld as possible.
Based on review of the actions implemented related to the One-Time Inspection - Small-Bore Piping Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitments 21 and 32 prior to the period of extended operation.
22. B.1.31 Periodic Surveillance and Preventive Maintenance Program and Commitment 22 The Periodic Surveillance and Preventive Maintenance Program aging management program managed the following aging effects: loss of material, cracking, change in material properties, loss of material by wear, and fouling. While primarily used for managing the effects of aging on internal surfaces, the program was used to managing loss of material from external surfaces for situations in which external and internal material and environment combinations were the same.
The team reviewed license renewal program basis documents, aging management review documents, procedures, maintenance and engineering training requirements, training records, updated safety analysis report and the safety evaluation report. The team interviewed the program owner, reviewed relevant condition reports and surveillances results.
Commitment 22 specified:
Enhance the Periodic Surveillance and Preventive Maintenance Program to include the activities described in the table provided in the program description of LRA Section B. 1.31. For each activity that refers to a representative sample, a representative sample will be selected for each unique material and environment combination. The sample size will be determined in accordance with Chapter 4 of EPRI 107514, Age-Related Degradation Inspection Method and Demonstration, which outlines a method to determine the number of inspections required for 90 percent confidence that 90 percent of the population does not experience degradation.
Procedure 3.47.31, Periodic Surveillance and Preventative Maintenance (PSPM)
Program, Revision 0, described conduct of this program. The program verified for miscellaneous components that aging effects were not occurring or were acceptable through the end of the period of extended operation. The licensee included components in this program not managed by other aging management programs. The program supplemented the guidance in the existing preventive maintenance and surveillance programs. The licensee created 48 separate groups of components that represented different material-environment combinations and planned to apply the sampling method to each group of components. The licensee stated that they would evaluate each component once every 5 years throughout the period of extended of operation. The licensee identified the initial list of components and scheduled the inspections expected to occur during Refuel Outage 28 in 2014. Procedure 3.47.31 required all maintenance and engineering personnel attend training related to identifying aging effects.
The team determined that the licensee revised their sampling method to agree with the sampling method described in GALL Report, Revision 2 that specified performing inspections on 20 percent of the sample population up to a maximum of 25 components.
The team determined that the licensee appropriately revised their commitment using their commitment change process and revised their updated safety analysis report in accordance with their 10 CFR 50.59 program.
The licensee planned to schedule the aging effect inspections to coincide with planned maintenance or modification activities. The licensee had not completed the scheduling of each component aging inspection for the first 5-year period at the time of this inspection. The licensee had created the online (12-month) and offline (24-month)recurring tasks that reminded the aging management coordinator to promulgate the component schedules to the individual system engineers and component engineers of the equipment to choose the most appropriate samples to inspect. The licensee expected that this would result in sample selections most likely to show evidence of aging (e.g., worst environment or oldest installed component).
Based on review of the actions implemented related to the Periodic Surveillance and Preventive Maintenance Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitments 22 prior to the period of extended operation.
23. B.1.33 Reactor Vessel Surveillance Program and Commitment 23 The Reactor Vessel Surveillance Program aging management program managed the reduction in fracture toughness of reactor vessel beltline materials to assure that the reactor pressure vessel pressure boundary function was maintained through the period of extended operation. The licensee received the NRC approval to use the BWRVIP Integrated Surveillance Program. As BWRVIP Integrated Surveillance Program capsule test reports become available for reactor pressure vessel materials representative of the Cooper Nuclear Station reactor vessel, the licensee would update any actual shift in the reference temperature for nil ductility transition of the reactor vessel material. In accordance with 10 CFR Part 50 Appendices G and H, the licensee reviewed relevant test reports to assure compliance with fracture toughness requirements and pressure temperature limits.
The team reviewed applicable program procedures, aging management program guidance, license renewal documents, updated safety analysis report, safety evaluation report, and industry documents. The team discussed the program with the NRC personnel and interviewed the program owner.
Commitment 23 specified:
Enhance the Reactor Vessel Surveillance Program to add that if the CNS license renewal capsule is removed from the reactor vessel without the intent to test it, the capsule will be stored in a manner which maintains it in a condition which would permit its future use, including during the period of extended operation, if necessary.
Enhance the program to ensure that the additional requirements that are specified in the final NRC safety evaluation for BWRVIP-116 will be addressed before the period of extended operation.
The team reviewed BWRVIP-116, BWR Vessel and Internals Project Integrated Surveillance Program (ISP) Implementation for License Renewal, dated July 2003 and the NRC safety evaluation report for BWRVIP-116. The team determined from interviews with the program owner that the licensee identified one recommendation from BWRVIP-116 that their program did not already require. Specifically, the licensee needed to add the requirement to submit a license amendment for the NRC approval if they planned to change their neutron fluence determination methodology.
The team verified Procedure 3.28.4, Integrated Surveillance Program, Revision 11 contained precautions to obtain the NRC approval if they needed to change their neutron fluence determination methodology and to determine if the desired methodology had been or would be benchmarked against existing dosimetry databases. The team determined that the licensee used the NRC-approved RAMA code as its neutron fluence methodology.
The team verified that the licensee had committed to meeting the prescribed capsule testing schedule. Further, the team verified that Procedure 3.28.4 contained guidance related to storing test capsules in a manner that would permit its future use, if the licensee removed the capsule without the intent to test it.
Based on review of the actions implemented related to the Reactor Vessel Surveillance Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the condition of Commitment 23 prior to the period of extended operation.
24. B.1.34 Selective Leaching Program and Commitment 24 The Selective Leaching Program aging management program managed the effects of aging by ensuring the integrity of components made of cast iron, bronze, brass, and other alloys exposed to condensation, raw water, steam, treated water, and soil (groundwater) that may lead to selective leaching. The licensee performed one-time visual inspections, hardness measurements, and destructive testing inspections of selected components to determine whether loss of material resulting from selective leaching occurred. Based on the results of the inspections, the licensee would determine whether any material environment combination experienced selective leaching.
The team reviewed licensee procedures, program documents, license renewal documents, safety evaluation report, and updated safety analysis report. The team interviewed the program owner, reviewed inspection records, and corrective action documents.
Commitment 24 specified:
Implement the Selective Leaching Program.
The team determined that the licensee reviewed for selective leaching in five environments: treated water, steam, raw water, condensation, and soil (groundwater).
The licensee inspected 78 components for selective leaching in 22 different systems.
The licensee initiated 17 condition reports 9 of which included gray cast iron in the service water and fire protection water systems. Because the gray cast iron/treated water material environment combination indicated evidence of selective leaching, the licensee initiated actions to monitor for the effects of aging related to selective leaching for gray cast iron components in a treated water environment. The team determined that the licensee developed a repetitive task to take a sample from the fire water system once every 5 years if an opportunistic inspection of a component in the fire water systems had not occurred.
Based on review of the actions implemented related to the Selective Leaching Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the condition of Commitments 24 prior to the period of extended operation.
25. B.1.36 Structures Monitoring Program and Commitment 25 The Structures Monitoring Program aging management program managed the effects of aging of structures and commodities through periodic inspections to ensure that aging degradation would be detected, evaluated, and repaired prior to any loss of intended functions.
The team reviewed plant procedures, program documents, updated safety analysis report, safety evaluation report, and license renewal documents. The team reviewed corrective action documents, interviewed the program owner and walked down selected plant areas. The team determined that the licensee based their inspection requirements on numerous industry documents that required structures be designed to withstand seismic events.
Commitment 25 specified:
Revise procedures to ensure the structures described in the LRA Section B.1.36 table are included in the program. Revise procedures to ensure the commodities described in the LRA Section B.1.36 table are inspected, as applicable. Enhance the Structures Monitoring Program to add guidance to inspect inaccessible concrete areas that are submerged or below grade which may become exposed due to excavation, construction or other activities. CNS will also inspect inaccessible concrete areas when observed conditions in accessible areas exposed to the same environment indicate that significant concrete degradation is occurring. Enhance the Structures Monitoring Program to perform inspections of elastomers (seals, gaskets, and roof elastomers) to identify cracking and change in material properties. Enhance the Structures Monitoring Program to perform an engineering evaluation of groundwater samples to assess aggressiveness of groundwater to concrete on a periodic basis (at least once every 5 years). CNS will obtain samples from a well that is representative of the groundwater surrounding below-grade site structures.
Samples will be monitored for Sulfates, pH and chlorides. Enhance the Structures Monitoring Program to add guidance to perform visual structural examinations of wood to identify loss of material and change in material properties. Enhance the Structures Monitoring Program to add guidance to perform visual structural monitoring of the oil tank bunker crushed rock fill to identify loss of form. Enhance the Structures Monitoring Program to clarify that structures with conditions classified as acceptable with deficiencies or unacceptable shall be entered into the Corrective Action Program. Supplement 1: NPPD will enhance the Structures Monitoring Program procedure to: a) include more detailed guidance on acceptance criteria (using ACI documents ACI 201.1R-92, and ACI 349.3R-96) to preclude potential inconsistent application of inspection criteria, and b) provide more detailed guidance on trending.
The team verified that the licensee had inspected their in-scope structures in accordance with the procedures that implemented their maintenance rule structures monitoring program. Further the team verified that the licensee had performed the following activities related to Commitment 25.
The team verified that Procedure 3-EN-DC-150, Condition Monitoring of Maintenance Rule Structures, Revision 2C1:
- (1) included the structures and commodities listed in the license renewal application;
- (2) specified inspecting elastomers (seals, gaskets, and roof elastomers) to identify cracking and change in material properties;
- (3) required inspecting wood structures to identify loss of material and change in material properties;
- (4) specified inspecting the oil tank bunker crushed rock fill to identify loss of form;
- (5) specified that structures with conditions classified as acceptable with deficiencies or unacceptable shall be entered into the corrective action program; and
- (6) included detailed guidance to preclude potential inconsistent application of inspection criteria and specified proper documentation to allow trending.
The team reviewed the groundwater sample records and evaluation performed prior to the period of extended operation and determined that the ground water parameters remained within the required limits. The team verified that Procedure 8.ENV.9, Groundwater Monitoring Program Sampling, Monitoring, and Administrative Requirements, Revision 9, specified that the license take samples from monitoring wells GMW-2, GMW-8, and GMW-10 to ensure they represented site soil conditions. The procedure required that the samples be taken once every 5 years, included monitoring for sulfates, pH and chlorides, and required an engineering evaluation of the groundwater samples to assess aggressiveness of groundwater on concrete.
The team verified that Procedure 3.6.5, Excavation and Ground Penetrating Activities, Revision 18, specified inspecting inaccessible concrete areas
- (1) that are submerged or below grade which may become exposed due to excavation, construction or other activities and
- (2) when observed conditions in accessible areas exposed to the same environment indicate that significant concrete degradation was occurring.
Based on review of the actions implemented related to the Structures Monitoring Program aging management program, the team concluded the aging management program would effectively manage the effects of aging during the period of extended operation. The team concluded the licensee met the conditions of Commitment 25 prior to the period of extended operation.
26. B.1.37 Thermal Aging and Neutron Irradiation Embrittlement of Cast Austenitic Stainless Steel and Commitment 29 The Thermal Aging and Neutron Irradiation Embrittlement of Cast Austenitic Stainless Steel Program aging management program managed the reduction of fracture toughness resulting from thermal aging and reduction of fracture toughness resulting from radiation embrittlement to prevent any in loss of intended function of reactor vessel internal components. This program evaluated cast austenitic stainless steel components in the reactor vessel internals and required non-destructive examinations as appropriate.
The team reviewed license renewal and industry documents and interviewed the program owner. The team determined that the licensee had not established a formal program because they believed that they did not have any cast austenitic stainless steel components that had more than 25 percent ferrite content.
Commitment 29 specified:
NPPD will confirm there are no CASS materials with greater than 25 percent ferrite or provide a flaw evaluation methodology for CASS internal components with greater than 25 percent ferrite for staff review and approval. This will be provided at least 2 years prior to the period of extended operation. NPPD expects to implement this commitment by a generic analysis sponsored by the BWRVIP in collaboration with EPRI.
The team determined that EPRI submitted BWRVIP-234 for review by the NRC in December 2009. At the time of this submittal, the licensee determined that they would use the NRC acceptance and approval of BWRVIP-234 to demonstrate that they had less than 25 percent ferrite in their cast austenitic stainless steel components. Because they believed that the NRC would approve BWRVIP-234 prior to January 18, 2014, the licensee did not provide a flaw evaluation methodology prior to January 18, 2012.
During this inspection, the NRC had not approved BWRVIP-234 and would not approve it by January 18, 2014. The team determined the following chronology related to review of BWRVIP-234. In a letter dated September 28, 2011 the NRC requested additional information. On September 18, 2012 EPRI responded to the requests for additional information. The NRC initiated a second request for additional information on April 24, 2013. The team determined that the licensee tracked completion of this commitment by Condition Report CNSLO-2011-00258.
Because the licensee had not entered the period of extended operation, the licensee revised the due date for this commitment to January 18, 2017, which matched the dates for the other commitments that will be completed after entering the period of extended operation. The licensee further indicated that they would implement the appropriate corrective actions if they were determined to exceed 25 percent ferrite in their cast austenitic stainless steel components. The team considered this an appropriate corrective action.
Based on review of the actions implemented related to the Thermal Aging and Neutron Irradiation Embrittlement of Cast Austenitic Stainless Steel aging management program, the team could not determine whether the program would effectively manage the effects of aging during the period of extended operation. Because of concerns related to determining the amount of ferrite in cast austenitic stainless steel, the team was unable to ensure the licensee met the conditions of Commitment 29; consequently, Commitment 29 remained open.
.02 Aging Management Programs without any Associated Commitments
