a. Inspection Scope
(IP 71002)
This inspection was performed to evaluate the thoroughness and accuracy of the applicant's scoping and screening of nonsafety-related structures, systems, and components (SSC), as required in 10 CFR 54.4(a)(2). Also, the team evaluated whether aging management programs will be capable of managing identified aging effects in an appropriate manner.
In order to evaluate scoping activities, the team selected a number of SSCs for review to evaluate whether the methodology used by the applicant appropriately addressed the nonsafety-related systems affecting the safety functions of a structure, system, or component within the scope of license renewal.
The team selected a sample of 23 of the 41 aging management programs developed by the applicant to verify the adequacy of the applicants guidance, implementation activities, and documentation. The team evaluated the programs to determine whether the applicant would appropriately manage the effects of aging and to verify that the applicant would maintain the safety functions of the SSCs during the period of extended operation. The team evaluated the applicants review and consideration of industry and plant-specific operating experience related to aging effects.
The team reviewed supporting documentation and interviewed applicant personnel to confirm the accuracy of the license renewal application conclusions. For a sample of plant structures and systems, the team walked down accessible portions of the systems to observe aging effects. During the plant walkdowns, the team reviewed the material condition of the SSCs.
b.1 Evaluation of Scoping of Nonsafety-Related Structures, Systems, and Components For scoping of nonsafety-related SSCs affecting safety-related SSCs, as required by 10 CFR 54.4(a)(2), the team reviewed the applicants program guidance and scoping results. The team assessed the thoroughness and accuracy of the methods used to identify the SSCs required to be within the scope of the license renewal application.
The team verified that the applicant had established procedures consistent with the NRC-endorsed guidance contained in Nuclear Energy Institute 95-10, Industry Guideline for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule, Revision 6, Appendix F, Sections 3, 4, and 5. The team assessed whether the applicant evaluated
- (1) nonsafety-related SSCs within the scope of the current licensing basis,
The team reviewed the license renewal drawings listed in the appendix. The applicant had color coded the drawings to indicate in-scope systems and components required by 10 CFR 54.4(a)(1), (a)(2), and (a)(3). The team interviewed personnel, reviewed program documents, and independently walked down numerous areas within the plant.
The areas walked down included:
- Reactor auxiliary building
- Fuel handling building
- Diesel generator rooms
- Turbine building and upper deck
- Diesel generator fuel oil storage tank A area
- Wet and dry cooling towers
- Firewater pump house and tanks
- Yard fire main
- Portions of the electrical distribution system associated with station blackout recovery For SSCs selected because of potential spatial interactions, where failure of nonsafety-related components could adversely affect adjacent safety-related components, the team determined that the applicant accurately categorized the in-plant configuration within the license renewal documents. The team determined the personnel involved in the process were knowledgeable and appropriately trained.
For SSCs selected because of potential structural interaction (seismic design of safety-related components potentially affected by nonsafety-related components), the team determined that the applicant accurately identified and categorized the structural boundaries within the program documents. Based on in-plant walkdowns and on independent sampling of the isometric drawings (identified by an asterisk (*) in the appendix) and the seismic boundary determinations, the team determined that the applicant appropriately identified the seismic design boundaries and correctly included the applicable components within the license renewal scope.
On June 27, 2016, the NRC issued a license amendment authorizing the transition of the applicants fire protection program to a risk informed, performance-based program based on the 2001 Edition of National Fire Protection Association (NFPA) Standard 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generation Plants. The applicant had transitioned their fire protection program in accordance with Amendment 248 of the facility operating license. In a response to a request for information letter (W3F1-2017-0002), dated January 16, 2017, the applicant identified they would update their License Renewal Application to reflect this change.
The team reviewed the applicants scoping of systems affected by this change, and reviewed a sample of aging management programs affected by this change.
In summary, the team concluded that the applicant had implemented an acceptable method of scoping nonsafety-related SSCs and that this method resulted in appropriate scoping determinations for the samples reviewed.
b.2 Evaluation of New Aging Management Programs The team reviewed 7 of the 13 new aging management programs to determine whether the applicant had established appropriate actions or had actions planned to manage the effects of aging as specified in NUREG-1801, Generic Aging Lessons Learned (GALL)
Report, Revision 2 (the GALL Report). The team independently reviewed site-specific operating experience to determine whether there were any aging effects for the systems and components within the scope of these programs that had not been identified when considering applicable industry operating experience.
The team selected in-scope SSCs to assess how the applicant maintained plant equipment material conditions under existing programs and to visually observe examples of nonsafety-related equipment determined to be within scope because of the proximity to safety-related equipment and the potential for failure as a result of aging effects.
.1 B.1.3 Buried and Underground Piping and Tanks Inspection (XI.M41)
The applicant established this new aging management program, consistent with the GALL Report, as modified by LR-ISG-2011-03, Changes to the Generic Aging Lessons Learned (GALL) Report Revision 2 Aging Management Program XI.M41, Buried and Underground Piping and Tanks, to manage the loss of material, cracking or changes in material properties resulting from general corrosion, and loss of material on external surfaces of buried and underground limited access components. The program specified prevention, mitigation, and inspection activities, including external coatings, quality of backfill, cathodic protection and periodic inspections. The applicant included all in-scope underground piping and components of carbon steel, gray cast iron, polymers, cementitious and concrete materials. This program is credited for plant drains, the emergency generator system, component cooling and auxiliary component cooling water systems, and the fire water system.
The applicant identified that they would manage the effects of aging through visual inspection either during opportunistic excavations for other maintenance or during planned excavations. The inspections will evaluate the condition of the external surfaces, the backfill, and protective coatings and wrappings of steel, stainless steel, and copper alloy on buried and underground components. The applicant will perform one excavation of each material type once every 10 years, beginning in the 10-year period prior to the period of extended operation.
The team reviewed the aging management program evaluation report, implementing procedures, and corrective action documents. The team also reviewed plant specific operating experience, cathodic protection system evaluation reports, and cathodic protection system surveys. The team interviewed engineers responsible for the buried pipe and coating programs and the cathodic protection systems.
The team concluded that the applicant had performed appropriate evaluations of the piping conditions and considered pertinent industry experience and plant operating history to determine the effects of aging on buried piping and tanks. The team concluded that, if implemented as described, the applicant developed guidance that would appropriately identify and address aging effects during the period of extended operation.
.2 B.1.4 Coating Integrity (XI.M42)
The applicant established this new aging management program, consistent with the GALL Report, as modified by LR-ISG-2013-01, Aging Management of Loss of Coating or Lining Integrity for Internal Coatings/Linings on In-Scope Piping, Piping Components, Heat Exchangers and Tanks, with exception, to manage aging effects where loss of coating or lining integrity could impact the components current licensing basis intended functions. The applicant will perform periodic visual inspections of components with coated surfaces in environments of raw water, treated water, lubricating oil or fuel oil.
For coated surfaces that do not meet the acceptance criteria, physical testing will be performed. The training and qualification of individuals must meet the standards endorsed in Regulatory Guide 1.54, Service Level I, II, and III Protective Coatings Applied to Nuclear Power Plants. The applicant will implement this program within the 10-year period prior to entering the period of extended operation.
The applicant requested an exception for this aging management program.
Exception For the Detection of Aging Effects element, the applicant proposed performing a one-time inspection of the internal coating of the 11-foot diameter carbon steel circulating water piping. The piping is in-service while the plant operates and provides the source to fill the wet cooling tower basin. The coal-tar coating, if it detached, would flow to the condenser water box affecting power generation but not any safety functions.
The team identified no concerns with this exception.
The team reviewed the license renewal application and the aging management program evaluation report. The team discussed the program with the responsible staff.
For the Coating Integrity program, the team concluded that the applicant had performed appropriate evaluations and considered pertinent industry experience to determine the in-scope components and systems. The team concluded that, if implemented as described, the applicant developed guidance that would appropriately identify and address aging effects during the period of extended operation.
.3 B.1.20 Metal Enclosed Bus Inspection (XI.E4)
The applicant established this new aging management program, consistent with the GALL Report, to manage aging of the electrical bus bar bolted connections, bus bar insulation and insulators, bus enclosure assemblies (internal and external), and elastomers. The program scope included safety-related 4.16kV metal enclosed bus sections between switchgear 3A3-S, 3AB3-S, and 3B3-S and the safety-related 480V metal enclosed bus sections between switchgear 3A31-S, 3AB31-S, and 3B31-S.
The program will inspect a sample of accessible bus bolted connections for increased connection resistance. Bus insulation or insulators will be visually inspected for signs of aging caused by thermal/thermoxidative degradation of organics/thermoplastics, radiation-induced oxidation, moisture/debris intrusion, or ohmic heating, as indicated by embrittlement, cracking, chipping, melting, discoloration, or swelling, which may indicate overheating or aging degradation. A combination of visual inspections and quantitative measurements such as thermography will be performed, as required. Internal bus supports or insulators will be visually inspected for structural integrity and signs of cracking.
assembly external surfaces will be visually inspected for evidence of loss of material caused by general, pitting, and crevice corrosion. Accessible elastomers (e.g., gaskets, boots, and sealants) will be inspected for changes in material properties (elastomer degradation) including surface cracking, crazing, scuffing, dimensional changes (e.g., ballooning and necking), shrinkage, discoloration, hardening, and loss of strength at least once every 10 years. Enclosure assembly internal surfaces will be visually inspected for evidence of loss of material. Internal portions of the enclosure assemblies will also be inspected for cracks, corrosion, foreign debris, excessive dust buildup, and evidence of water intrusion.
The applicant will perform inspections before the period of extended operation, and at least once every 10 years, unless visual inspections are used as the only method to inspect accessible bolted connections. If the applicant uses only visual inspection methods for accessible bolted connection inspection, the inspection will be completed prior to the period of extended operation and at least once every five years thereafter.
This method is consistent with the alternative method described in the GALL Report.
The team reviewed applicable license renewal program basis documents, aging management program evaluation report, existing maintenance procedures, plant specific operating experience, and preventive maintenance requirements. The team interviewed license renewal project personnel and the responsible plant and design engineers. The team walked down all the in-scope metal enclosed buses.
The team concluded that for the Metal Enclosed Bus Inspection program, the applicant had performed appropriate evaluations and considered pertinent industry experience and plant operating history to determine the effects of aging for the metal enclosed buses. The team concluded that, if implemented as described, the applicant developed guidance that would appropriately identify and address aging effects during the period of extended operation.
.4 B.1.24 Non-EQ Inaccessible Power Cables ( 400 V) (XI.E3)
The applicant established this new aging management program, consistent with the GALL Report, with exception, to manage the effects of reduced insulation resistance on inaccessible power cables (greater than or equal to 400 V) exposed to adverse localized environments caused by significant moisture. The applicant had no in-scope safety-related cables installed below grade.
The applicant requested an exception for this aging management program.
Exception For the Preventive Actions element, the applicant cannot prevent the 480V electric driven fire pump (FP MPMP0002) and the electric driven jockey fire pump cables from being exposed to significant moisture even with increased inspection frequency.
Periodic manhole inspections will be performed to minimize this exposure, but the inspection frequency cannot be increased to prevent these cables from being exposed to significant moisture.
The applicant took this exception to the Preventive Actions element because of environmental conditions surrounding the in-scope cables. The applicant could not prevent the in-scope 480V electric-driven fire pump cables and the electric-driven jockey fire pump cables from being exposed to significant moisture resulting from site elevation.
The manholes and duct banks housing these cables are continuously submerged above the cable support assemblies from ground water penetration since the site elevation is below river elevation. As a result the applicant had chosen to perform annual inspections of the cables and cable support assemblies. A review of site historical operating experience identified only one medium-voltage cable failure and that failure was not attributable to moisture intrusion.
The team held numerous discussions with the applicant about their efforts to mitigate the in-scope cables exposure to submergence and their current and proposed process for inspections. The applicant opened and dewatered an in-scope manhole for the team to inspect and observe the as-found conditions of the cables, cable support assemblies and the structural condition of the cable vault and ducting. The applicant had planned to use the sites maintenance program and existing model work orders to perform visual inspections of the in-scope cables and cable support assemblies. After reviewing existing work orders and the open manhole conditions, the applicant identified that enhancements to their work orders and inspection process for the cables and manholes would be appropriate. As part of their aging management program, the applicant was developing a cable reliability program using Procedure EN-DC-346, Cable Reliability Program, Revision 6, and guidance from several industry guidance documents, including Electric Power Research Institute (EPRI) TR-1020804, Aging Management Development Guidance AC and DC Low-Voltage Power Cable Systems for Nuclear Power Plants, to improve their cable management process. The in-scope cabling had ethylene propylene rubber (EPR) insulation with jacketing of black heavy-duty chlorosulphonated polyethylene for low moisture absorption. The cables were designed for underground and aboveground applications in wet or dry locations and direct burial.
The applicant stated the in-scope cables did not have splices.
The program specified annual manhole inspections to assess whether cables and cable support assemblies are intact. The applicant discussed the enhancements to the work order process for the in-scope cables that will significantly improve the visual inspection process. In addition, the applicant will electrically test the inaccessible power cabling prior to entering the period of extended operation and once every six years thereafter.
The program stated the testing will be a proven test for detecting deterioration of the insulation system caused by wetting or submergence, such as Dielectric Loss (Dissipation Factor/Power Factor), AC Voltage Withstand, Partial Discharge, Step Voltage, Time Domain Reflectometry, Insulation Resistance and Polarization Index, Line Resonance Analysis, or other state-of-the-art testing at the time the test is performed.
The program will trend and track the results for condition monitoring, and the applicant will use the Structures Monitoring program for inspection and management of the cable vault structures. After discussions and review, the team had no significant concerns with the exception and concluded the licensee could provide reasonable assurance that the aging effects for the in-scope cables would be appropriately managed through the enhanced inspection and testing program.
The team reviewed applicable license renewal program basis documents, aging management program evaluation report, program procedures, and records for completed maintenance activities. In addition, the team reviewed condition records from the corrective action database for relevant plant operating experience documents. The team interviewed plant personnel and reviewed maintenance work orders, manhole inspection results, and records regarding water removed from manholes.
The team concluded that for the Non-EQ Inaccessible Power Cables program, the applicant had performed appropriate evaluations and considered pertinent industry experience and plant operating history to determine the effects of aging for inaccessible cables. The team concluded that, if implemented as described, the applicant developed guidance that would appropriately identify and address aging effects during the period of extended operation.
.5 B.1.26 Non-EQ Insulated Cables and Connections (XI.E1)
The applicant established this new aging management program, consistent with the GALL Report, to manage the aging of insulated cables and connections exposed to adverse localized environments caused by heat, radiation, or moisture. The monitored aging effects included cable and connection jacket surface anomalies, such as embrittlement, discoloration, cracking, melting, swelling, or surface contamination. The program population will consist of all accessible cables and connections such that the program sample will represent, with reasonable assurance, all cables (accessible and inaccessible) and connections in adverse localized environments.
The applicant planned to monitor the aging effects through periodic visual inspections.
The program acceptance criteria established that accessible cables and connections were to be free from unacceptable visual indications of surface anomalies. The applicant defined an unacceptable indication as a noted condition or situation that, if left unmanaged, could lead to a loss of intended function. The applicant will complete the first inspection sample of these components prior to entering the period of extended operation and once every 10 years thereafter.
The team reviewed relevant license renewal program basis documents, aging management review documents, procedures, plant specific operating experience, and preventive maintenance requirements. The team interviewed the license renewal project personnel and walked down a sample of accessible areas within the plant where cable trays and exposed cables were installed in adverse localized environments. The applicant identified that EPRI TR 109619, Guideline for Management of Adverse Localized Environments, dated June 1999 will be used as guidance in performing the inspections.
The team concluded that for the Non-EQ Insulated Cables and Connections program, the applicant performed appropriate evaluations and considered pertinent industry experience and plant operating history to determine the effects of aging for cables and connections exposed to adverse localized environments. The team concluded that, if implemented as described, the applicant developed guidance that would appropriately identify and address aging effects during the period of extended operation.
.6 B.1.28 One-Time Inspection (XI.M32)
The applicant established this new aging management program, consistent with the GALL Report, to manage the aging of components for loss of material, cracking, and reduction of heat transfer internal to plant systems. The applicant will conduct these one-time inspections to identify and characterize the material conditions in representative low-flow and stagnant areas of plant piping and components addressed by the Water Chemistry Control - Primary and Secondary program, the Diesel Fuel Monitoring the Oil Analysis programs, the circulating water concrete intake piping internals, and the reactor vessel flange leak detection line. The planned visual and volumetric inspections would provide direct evidence that no loss of material resulting from corrosion in treated liquid environments was present. The applicant will implement this program within the 10 year period prior to entering the period of extended operation.
The team reviewed the license renewal application and the aging management program evaluation report. The applicant proposed an acceptable method to select their sample population (20 percent of the sample population up to a maximum of 25 components)and specified that the sampling would occur for each set of common material and environment combinations.
For the One Time Inspection program, the team concluded that the applicant had performed appropriate evaluations and considered pertinent industry experience and plant operating history to determine the effects of aging in the affected systems. The team concluded that, if implemented as described, the applicant developed guidance that would appropriately identify and address aging effects during the period of extended operation.
.7 B.1.35 Selective Leaching (XI.M33)
The applicant established this new aging management program, consistent with the GALL Report, to manage the aging of components subject to selective leaching of materials. The affected components included material made of gray cast iron and copper alloy with greater than 15 percent nickel (i.e., bronze or brass) exposed to raw water, treated water, and ground water that may lead to selective leaching. The program will include a one-time visual inspection and mechanical testing of a sample of components with metallurgical properties susceptible to selective leaching to demonstrate the absence of this aging effect, or to implement an aging management program if a loss of material has occurred.
The team reviewed the license renewal application, the aging management program evaluation report, and the list of components subject to selective leaching. The majority of the components consisted of gray cast iron piping and valves in the fire protection system. The team discussed the program evaluations and planned activities with the responsible staff.
For the Selective Leaching program the team concluded that the applicant had performed appropriate evaluations and considered pertinent industry experience and plant operating history to determine the effect of aging in components and systems subject to this mechanism. The team concluded that, if implemented as described, the applicant developed guidance would appropriately identify and address aging effects during the period of extended operation.
b.3 Evaluation of Existing Aging Management Programs The team reviewed 16 of the 28 existing programs credited with aging management to determine whether the applicant had taken or planned to take appropriate actions to manage the effects of aging as described in the GALL Report and any related License Renewal Interim Staff Guidance (LR-ISG).
The team reviewed site-specific operating experience to determine whether there were any aging effects for the systems and components within the scope of these programs that had not been identified from the applicants review of industry operating experience.
The team evaluated whether the applicant implemented or planned to implement appropriate actions to manage the effects of aging. These programs had established procedures, records of past corrective actions, and previous operating experience related to applicable components. Some programs required enhancements and took exceptions (i.e., changes to program aspects that will be implemented prior to the period of extended operation) to be consistent with the GALL Report.
The team walked down selected in-scope SSCs to assess how the applicant maintained plant equipment under the current operating license; to observe examples of nonsafety- related equipment determined to be in-scope because of the proximity to safety-related equipment; and, to assess the potential for failures as a result of aging effects.
.1 B.1.1 Bolting Integrity (XI.M18)
This was an existing program, consistent with the GALL Report, after one exception and three enhancements, credited with managing aging of safety-related and nonsafety-related closure bolting for pressure retaining components. The program included the selection of bolting materials and use of lubricants and sealants consistent with guidance in EPRI NP-5769, Degradation and Failure of Bolting in Nuclear Power Plants, and recommendations provided in NUREG-1339, Resolution of Generic Safety Issue 29:
Bolting Degradation or Failure in Nuclear Power Plants, to prevent or mitigate degradation and failure of safety-related bolting. The applicant selected bolting materials, lubricants, and sealants in accordance with industry guidance. In addition, the applicant established torque values and restricted the use of molybdenum disulfide as specified in industry guidelines and manufacturer recommendations. Maintenance practices and bolting replacement activities included proper gasket activation, preload, torqueing, and fit-up of bolting in accordance with manufacturer, vendor, or industry recommendations.
The applicant requested an exception for this aging management program.

The program used periodic inspections and walkdowns to monitor for material degradation and leakage, including coatings and insulation degradation, and loss of material. The program included confirmation of the integrity of coated surfaces as a means to effectively manage the effects of corrosion on metallic surfaces. Accessible mechanical components are inspected at least once per refueling cycle; inaccessible mechanical components or areas that have limited access caused by safety, security, or other considerations will be inspected when plant conditions permit, but at a frequency that will ensure the components intended function is maintained. When required by the ASME Code, inspections are conducted in accordance with the code requirements. In the absence of such requirements, plant-specific visual inspections are performed of metallic surfaces using procedures implemented by inspectors qualified through plant programs. Component surfaces that are insulated and in an environment of condensation and insulated outdoor components are periodically inspected at such intervals that would ensure the components intended function.
The applicant identified that several enhancements were necessary to ensure consistency with the GALL Report as modified by LR-ISG-2011-03.
Enhancements For the Detection of Aging Effects element, revise procedures to:
- Include instructions to perform a 100 percent visual inspection of accessible polymeric component surfaces. The visual inspection should identify indicators of loss of material caused by wear to include dimensional change, surface cracking, crazing, scuffing, and for flexible polymeric materials with internal reinforcement, the exposure of reinforcing fibers, mesh, or underlying metal. In addition, 10 percent of the available flexible polymeric surface area should be physically manipulated to augment the visual inspection to confirm the absence of hardening and loss of strength;
- Conduct representative inspections during each 10-year period of insulated surfaces of each material type (e.g., steel, stainless steel, copper alloy, aluminum)in an air-outdoor or condensation environments;
- Remove insulation in order to perform a visual inspection of a representative sample of insulated indoor component surfaces in an environment of condensation and outdoor component surfaces. The inspections shall include a minimum of 20 percent of the in-scope piping length for each material type (e.g., steel, stainless steel, copper alloy, aluminum), or for components with a configuration which does not conform to a 1- foot axial length determination, 20 percent of the surface area.
Alternatively, insulation can be removed and a minimum of 25 inspections performed that can be a combination of 1-foot axial length sections and individual components for each material type;
- Include inspection locations based on the likelihood of corrosion under insulation;
- Allow subsequent inspections to consist of an examination of the exterior surface of the insulation for indications of damage to the jacketing or protective outer layer of the insulation, if no loss of material caused by general, pitting or crevice corrosion, beyond that which could have been present during initial construction and no evidence of cracking is identified after the initial inspection;
- Ensure that if the external visual inspections of the insulation reveal damage to the exterior surface of the insulation or there is evidence of water intrusion through the insulation, periodic inspections under the insulation will continue at such intervals that would ensure the components intended function; Enhancements
- Provide guidance that removal of tightly adhering insulation that is impermeable to moisture is not required unless there is evidence of damage to the moisture barrier.
However, the entire population of in-scope accessible piping component surfaces that have tightly adhering insulation will be visually inspected for damage to the moisture barrier with the same frequency as for other types of insulation inspections. These inspections will not be credited towards the inspection quantities for other types of insulation.
For the Acceptance Criteria element, include the following criteria:
- Stainless steel should have a clean and shiny surface with no discoloration;
- Other metals should not have any abnormal surface indications;
- Flexible polymeric materials should have a uniform surface texture and color with no cracks and no unanticipated dimensional change, no abnormal surface with the material in an as new condition with respect to hardness, flexibility, physical dimensions, and color;

.7 B.1.13 Fire Water System (XI.M27)
This was an existing program, consistent with the GALL Report as modified by LR-ISG-2012-02, Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion under Insulation, after enhancement and exception, credited with managing loss of material, flow blockage caused by fouling, and loss of coating integrity for in-scope long-lived, passive, water-based fire suppression system components using periodic flow testing and visual inspections in accordance with the 2011 edition of NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. The program is credited with managing loss of material in systems including dry-pipe systems downstream of manual isolation valves or deluge valves which may not drain correctly or allow water to collect in piping sections.
System flow testing, including that of underground headers, hose stations, main drains, and selected inspector test valves are performed to ensure the system maintains its intended function. Fire suppression water system parameters monitored during periodic flow testing are fire pump discharge pressure, pressure at fire hydrants and local areas being tested (e.g., local static and flow pressure at main drain valves being opened for testing). Fire water system pressure is continuously monitored such that a loss of pressure is immediately detected and corrective action is initiated. When visual inspections are used to detect loss of material and fouling, the inspection technique used will be capable of detecting surface irregularities that could indicate wall loss caused by corrosion, corrosion product deposition, and flow blockage caused by fouling.
The applicant requested exceptions for this aging management program. The applicant modified several previously identified exceptions in a subsequent responses to NRC Request for Information correspondence.
