RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION Page 2 of 3
Dear Sir or Madam:
By Reference 1, Energy Northwest requested the renewal of the Columbia Generating Station (Columbia) operating license. Via Reference 2, the Nuclear Regulatory Commission (NRC) requested additional information related to the Energy Northwest submittal. Transmitted herewith in the attachment is the Energy Northwest response to the Request for Additional Information (RAI) contained in Reference 2. The RAI in Reference 2 was specific to the Cooling Unit Inspection Program, requesting a justification for a one-time inspection rather than a periodic inspection program. References 3, 4, 5, and 6 deferred responses to similar RAIs about the Diesel System Inspection, Diesel-Driven Fire Pump Inspection, Flexible Connections Inspection, Monitoring and Collection Systems, and Service Air Inspection. In RAI B.2.14-1, the NRC requested that Energy Northwest justify how the one-time inspection satisfied one of the following criteria for the use of a one-time inspection program: (a) the aging effect is not expected to occur but the data is insufficient to rule it out with reasonable confidence; (b) the aging effect is expected to progress very slowly in the specified environment, but the local environment may be more adverse than that generally expected; and (c) the characteristics of the aging effect include a long incubation period. Energy Northwest determined that, for the 6 programs, the site-specific operating experience has not identified an aging effect, but that the data is insufficient to rule it out with reasonable confidence. However, based on reviews of the Generic Aging Lessons Learned (GALL) Report, NUREG 1801, revision 2, Energy Northwest is revising the LRA to change the 6 one-time inspections to base-line inspections prior to the period of extended operation (PEO) with subsequent opportunistic inspections of components within the program scope during the PEO. The programs include a provision to verify that each material and environment combination is inspected with in a specified time frame. Enclosures 1 through 6 contain the applicable revised pages of Amendment 21 to the LRA. Each enclosure contains the revised pages for one of the programs modified in response to the RAIs. This group of 6 enclosures is provided to aid in the review of the individual RAIs. Six revised commitments are included in this response. If you have any questions or require additional information, please contact Abbas Mostala at (509) 377-4197.

RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION Page 1 of 6 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION "Request for Additional Information for the Review of the Columbia Generating Station, License Renewal Application," (ADAMS Accession No. ML103010080) Kichline RAI B.2.14-1
Background:
Generic Aging Lessons Learned (GALL) aging management program (AMP) XI.M32 states that use of a one-time inspection is appropriate when (a) an aging effect is not expected to occur but the data is insufficient to rule it out with reasonable confidence; (b) an aging effect is expected to progress very slowly in the specified environment, but the local environment may be more adverse than that generally expected; or (c) the characteristics of the aging effect include a long incubation period. GALL AMP XI.M32 also states that for these cases, the one-time inspection should provide confirmation that either the aging effect is indeed not occurring, or the aging effect is occurring very slowly so as not to affect the component or structure's intended function during the period of extended operation. GALL AMP XI.M32 also states that one-time inspections may be used to verify the system-wide effectiveness of an AMP at inspection locations in the system or component based on the aging effect. In license renewal application (LRA) Section B.2.14, the applicant stated that its Cooling Unit Inspection Program will be used to detect and characterize the material conditions of aluminum, steel, copper alloy and stainless steel cooling unit components that are exposed to condensation (internal or external) environment. The applicant also stated that the inspection would provide direct evidence as to whether, and to
- what extent, a loss of material due to crevice, galvanic, general, pitting, or microbiological influenced corrosion, reduction in heat transfer due to fouling of heat exchanger tubes and fins, or cracking of aluminum components has occurred, or is likely to occur, that could result in a loss of intended function.
GALL Report item VII.G-23 recommends GALL AMP XI.M38, "Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components" to manage loss of material for steel piping exposed internally to moist air or condensation. GALL AMP XI.M38 includes periodic inspections of the internal surfaces of components to manage loss of material. GALL Report items VII.F1 -1, VII.F2-12, and VII.F2-14 recommend a plant-specific aging management program and require further evaluation to manage the loss of material, pitting and crevice corrosion for stainless steel, aluminum, and copper, respectively.
RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION Page 2 of66 Issue: It is not clear to the staff how a one-time inspection program is appropriate to manage loss of material and cracking for aluminum exposed to condensation (external) and loss of material for steel exposed to condensation (internal) given that (a) industry experience has shown that aging is expected for these material and environment combinations (b) the GALL Report recommends periodic inspection programs to manage aging for these material and environment combinations; and (c) a one-time inspection program is only to be used when an aging effect is not expected or is expected to progress very slowly. Request: Justify how the one-time inspections proposed by the Cooling Units Inspection Program is adequate by explaining how, for each component managed by the program, one of the following criteria for use of a one-time inspection is satisfied: (a) the aging effect is not expected to occur but the data is insufficient to rule it out with reasonable confidence; (b) the aging effect is expected to progress very slowly in the specified environment, but the local environment may be more adverse than that generally expected; and (c) the characteristics of the aging effect include a long incubation period. Energy Northwest Response: The Cooling Units Inspection Program was credited for steel and stainless steel Diesel Building heating, ventilation and air conditioning (HVAC) drain pans and drain piping, Pump House HVAC drain pans and piping, Radwaste Building HVAC drain pans and piping, and Reactor Building HVAC drain pans, piping and components where a loss of material is not expected to occur but the data is insufficient to rule it out with reasonable confidence, since the drain pan and drain piping internal surfaces have not been inspected. Site specific operating experience has not identified a loss of material in drain pans or piping. However, the condition of the drain pans, piping and components has not been confirmed; air handling (cooling) unit maintenance and surveillance activities have been focused on the coils but have observed no leakage. By design, cooling units are self-draining. As such, a one-time inspection was credited for these components to verify that there are no aging effects requiring management for the subject components or to identify appropriate corrective actions, including possible programmatic oversight (based on the actual condition of the drain pans, piping and components). Furthermore, as described in the first annual update of the LRA (EN Letter G02-10-094), leakage was detected from ductwork downstream of Radwaste Building HVAC air handling unit WMA-AH-51A due to a dent in the bottom of the housing which allowed condensation to collect rather than drain off as designed. The collected water was removed but no corrosion was identified in the housing. The Cooling Units Inspection Program was also credited for the external surfaces of cooling unit coils (tubes and fins) for.cooling coils WMA-CC-51A2, 51B2, 52A2, and 52B2 which are not supplied by standby service water and, as such, are not within the scope of the Open-
RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION Page 3 of 6 Cycle Cooling Water Program. Site-specific operating experience has not identified cracking, loss of material or reduction in heat transfer and the heat transfer function of the coils is not managed by another program, but the data may not be sufficient to rule out the aging effects with reasonable confidence. As indicated by the use of generic note E (and listing of GALL Report items VII.F1-1, VII.F2-12, or VII.F2-14) or use of generic note H with no GALL report item listed, the Cooling Units Inspection Program is a plant-specific aging management program (AMP) for materials other than steel. This could have been more clearly described in LRA Appendix B.2.14. Also, industry operating experience reflected in NUREG-1801, Rev. 1 Chapter VII is more conservative in that aging is expected for components exposed to condensation. Therefore, the Cooling Units Inspection Program is modified in the attached LRA amendment to:
- 1. Clarify that it is a plant-specific AMP for the various materials in the scope of the program (including steel),
- 2. Change the one-time inspection to baseline inspections of each cooling unit material exposed to condensation prior to the period of extended operation,
- 3. Describe sample population selection and limits, as well as acceptance criteria,
- 4. Include opportunistic inspection of components within the scope of the program during maintenance, repair, or surveillance activities when surfaces are made available for inspection through the period of extended operation, and
- 5. Include trending of the results of these inspections to ensure that each material exposed to condensation has been examined via opportunistic inspection within a 5 year time period. Ifopportunistic inspections have not occurred within the 5-year interval, appropriate actions will be taken to ensure these inspections are performed As modified, the Cooling Units Inspection Program, which is a new program for Columbia, is a combination of one-time inspections collecting baseline information on actual cooling unit material-condition and opportunistic inspections thereafter to ensure that existing environmental conditions in cooling units and their drains are not causing material degradation that could result in a loss of component intended function during the period of extended operation. During the implementation phase (following receipt of the renewed license) and consistent with the response to NRC request for additional information (RAI) B.2.A-1, approved procedures will be revised or developed to direct these inspections. Per plant procedures, personnel performing VT-1, 2, or 3 inspections, ultrasonic examinations in accordance with ASME Section XI, and other nondestructive examinations in accordance with ASME Section V or Section Xl are required to be trained in accordance with ASME requirements. Training requirements for all inspections will be consistent with the requirements of 10 CFR 50 Appendix B. In addition, the sample population for the baseline inspections of the Cooling Units Inspection Program will be the same as that applied to the One-Time Inspections, which verify the effectiveness of existing aging management programs, in response to NRC

Amendment 21 addressing the required changes. is provided in the enclosure to this letter. Similar situations exist for the following AMPs, where plant-specific operating experience led to the conclusion that aging effects were not expected but data may not be sufficient to rule out the aging effect(s) with reasonable confidence. No occurrences of the aging effects were identified through a review of site operating experience, but actual material condition had not been determined.

The effect of precipitation is minimized by the physical arrangement of the EDG lines and any moisture that does collect is drained via a loop seal to an equipment drain. 2 Environment in the FP diesel exhaust lines is predominantly outdoor air with infrequent, and for short duration, exposure to diesel exhaust. The FP diesel exhaust lines are protected from precipitation by water shield caps. A cooling circuit in the FP diesels contains antifreeze, which is not chemistry controlled, is also exposed to river water (taken from the fire water supply), and is evaluated as raw water. This unique environment is not addressed by any other program. 3 Various environments where thermal exposure or ionizing radiation may result in elastomer degradation. Elastomer degradation, such as loss of material, for flexible connections in HVAC systems exposed to uncontrolled indoor air are also included based on re-evaluation of operating experience. 4 Raw (drainage) water, previously treated water that is no longer chemistry controlled, and plant sanitary drains with intermittent exposure to raw sewage. 5 Compressed air that is expected to be dry, but must be confirmed due to infrequent connection to other air sources that do not have air dryers.
RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION Page 5 of 6 Appendix B section. In these situations, industry operating experience reflected in NUREG-1 801 is more conservative, with aging effects expected to occur for the listed materials in the listed environments. Therefore, the above AMPs are also modified in the attached LRA amendment to:
- 1. Clarify that each is a plant-specific AMP,
- 2. Change the one-time inspection to baseline inspections of each material exposed to each environment prior to the period of extended operation,
- 3. Describe sample population selection and limits, as well as acceptance criteria
- 4. Include opportunistic inspection of components within the scope of the program during maintenance, repair, or surveillance activities through the period of extended operation, and
- 5. Include trending of the results of these inspections to ensure that each material and environment combination has been examined via opportunistic inspection within a 5 year time period. If opportunistic inspections have not occurred within the 5-year interval, appropriate actions will be taken to ensure these inspections are performed As modified, the AMPS, which are new programs for Columbia, are each a combination of one-time inspections collecting baseline information on actual material conditions and opportunistic inspections thereafter to ensure that existing environmental conditions are not causing material degradation that could result in a loss of component intended function during the period of extended operation. During the implementation phase (following receipt of the renewed license) and consistent with the response to NRC request for additional information (RAI) B.2.A-1, approved procedures will be revised or developed to direct these inspections. Per plant procedures, personnel performing VT-1, 2, or 3 inspections, ultrasonic examinations in accordance with ASME Section XI, and other nondestructive examinations in accordance with ASME Section V or Section XI are required to be trained in accordance with ASME requirements. Training requirements for all inspections will be consistent with the requirements of 10 CFR 50 Appendix B. In addition, the sample population for the baseline inspections will be the same as that applied to the One-Time Inspections, which verify the effectiveness of existing aging management programs, in response to NRC RAI B.2.A-2 and B.2.A-3.
Amendment 21 addressing the required changes is provided in the enclosure to this letter. In addition, updates of LRA Tables 3.3.2-14, 3.3.2-34, 3.3.2-36, 3.3.2-37 and 3.3.1, Table A-1 item 23, and Section B.2.23 are provided to relocate HVAC system flexible connections from the External Surfaces Monitoring Program to the Flexible Connection Inspection Program. Loss of material due to wear was also added as an aging effect for flexible connections in the HVAC systems based on plant-specific operating experience.
RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION Page 6 of 6 This completes the responses to the following NRC requests for additional information (RAIs): Other Programs Amendment 21 also includes the similar changes (specified above as items 1-5) for the additional 5 programs presented in the table below.

Columbia Generating Station License Renewal Application Technical Information A.1.2.12 Chemistry Program Effectiveness Inspection The Chemistry Program Effectiveness Inspection detects and characterizes the condition of materials in representative low flow and stagnant areas of systems with water chemistry controlled by the BWR Water Chemistry Program or the Closed Cooling Water Chemistry Program, and with fuel oil chemistry controlled by the Fuel Oil Chemistry Program. The inspection provides direct evidence as to whether, and to what extent, a loss of material due to corrosion has occurred. The inspection also determines whether cracking due to SCC of susceptible materials in susceptible locations has occurred. The Chemistry Program Effectiveness Inspection is a new one-time inspection that will be implemented prior to the period of extended operation. The inspection activities will be conducted within the 10-year period prior to the period of extended operation. A.1.2.13 Closed Cooling Water Chemistry Program The Closed Cooling Water Chemistry Program mitigates degradation of components that are within the scope of license renewal and contain closed cooling water. The program manages the relevant conditions that could lead to the onset and propagation of a loss of material due to corrosion or erosion, cracking due to SCC, or reduction in heat transfer due to fouling through proper monitoring and control of corrosion inhibitor concentrations consistent with EPRI closed cooling water chemistry guidelines. The Closed Cooling Water Chemistry Program includes corrosion rate measurement in reactor building closed cooling water locations and is supplemented by the one-time Chemistry Program Effectiveness Inspection and Heat Exchangers Inspection, which provide verification of the effectiveness of the program in managing the effects of aging. The Closed Cooling Water Chemistry Program is an existing program that requires enhancement prior to the period of extended operation.

Baseline inspections will be established on a sample population of subject components determined by engineering evaluation to identify evidence of cracking (of aluminum), a loss of material, or fouling, prior to the period of extended operation. Opportunistic inspections will be conducted, thereafter, when components are opened for maintenance, repair, or surveillance and surfaces are made available for inspection. For baseline inspections, the sample population will be 20% of the total population for each material - environment - aging effect group, up to a maximum of 25 inspections per group and, where practical, will be focused on the components most susceptible to aging, such as due to their time in service, the severity of conditions during normal plant operation, and the lowest design margins. Inspection of the sample population will be conducted within the 10-year period prior to the period of extended operation, and will serve as a baseline for future inspections. Any evidence of degradation that could lead to a loss of component intended function will be documented and evaluated through the Columbia corrective action program, including provisions for increasing the inspection sample size and locations. Insert E into pagqe B-67 The Cooling Units Inspection Program comprises baseline inspections prior to the period of extended operation and opportunistic inspections when components are opened for maintenance, repair, and surveillance thereafter. Baseline inspections are used to characterize material conditions and include provisions for increasing the inspection sample size and locations if degradation is detected. The results of baseline inspections are considered to ensure that opportunistic inspections thereafter will detect aging prior to a loss of component intended function.

Columbia Generating Station License Renewal Application Technical Information Insert B into page B-68 Inspection findings will be documented and evaluated by assigned engineering personnel. The inspection findings will be reviewed to ensure that each material exposed to condensation has been examined via opportunistic inspection within a 5 year time period. If opportunistic inspections have not occurred within the 5-year interval, appropriate actions will be taken to ensure these inspections are performed. Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program with subsequent adjustments to the program made as necessary. Insert C into page B-68 Indications or relevant conditions of degradation detected during the inspections will be compared to pre-determined acceptance criteria established by engineering evaluation of the pertinent design standard. Unacceptable inspection findings will include visual evidence of a loss of material or reduction in heat transfer due to fouling, a reduction in wall thickness where appropriate, or evidence of cracking of aluminum obtained by enhanced visual, surface, or volumetric examination. If the acceptance criteria are not met, then the indications and conditions will be evaluated under the Columbia corrective action program to determine whether they could result in a loss of component intended function during the period of extended operation or prior to the next opportunity for inspection. Insert D into page B-68 The Cooling Units Inspection Program is a new plant-specific program for which plant operating experience has not shown the occurrence of the aforementioned aging Program effects. Th provides for confirmation of material conditions before entering rg the period of extended operation, and detection of aging effects prior to loss of component intended function during the period of extended operation. The elements comprising the program activities will be consistent with industry practice. NUREG-1801, Revision 1, is based on industry operating experience through January 2005. Recent -industry operating experience has been reviewed for applicability, with only general indication that inspection of internal surfaces during the performance of periodic surveillance and maintenance activities has proven effective in maintaining the material condition of plant systems, structures, and components. Future operating experience is captured through the normal operating experience review process, which will continue through the period of extended operation.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-77 The Diesel Systems Inspection Program is a new plant-specific program for Columbia. The program will consist of inspections of the steel and stainless steel exhaust piping components for the Division 1, 2, and 3 diesels in the Diesel Engine Exhaust (DE) System, including the loop seal drains from the exhaust piping. The Diesel Systems Inspection Program will manage the effects of loss of material due to corrosion and cracking of stainless steel components. The Diesel Systems Inspection Program will comprise baseline inspections prior to the period of extended operation followed by opportunistic inspections when components are opened for maintenance, repair, or surveillance to ensure that the existing environmental conditions in subject components are not causing material degradation that could result in a loss of component intended function during the period of extended operation. Implementation of this program will ensure that the integrity of the subject components will be maintained consistent with the current licensing basis during the period of extended operation. The Diesel Systems Inspection Program is a new condition-monitoring program. Inspection of a sample population will be conducted within the 10-year period prior to the period of extended operation and will serve as a baseline for future inspections. Insert B into page B-77 The Diesel Systems Inspection Program is a new plant-specific Columbia program for License Renewal. NUREG-1801 includes an Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program (XI.M38) that is focused on steel components and the loss of material aging effect. Rather than necessitating enhancements and exceptions to the NUREG-1801 program, a plant-specific program is credited. The Diesel Systems Inspection Program is a new plant-specific program that is evaluated against the ten elements described in Appendix A of the Standard Review Plan of License Renewal Applications for Nuclear Power Plants, NUREG-1800, Revision 1. The results of an evaluation for each element are provided below. Amendment 21 Management Programs Aging Management Programs Page B-77a Page B-77a Amendment 21
Columbia Generating Station License Renewal Application Technical Information Insert C into page B-77 Prior to the period of extended operation, the Diesel Systems Inspection Program includes baseline inspection of a sample population followed by opportunistic inspection of the steel and stainless steel exhaust piping components exposed to an air-outdoor environment, and the loop seal drains from the exhaust piping that are exposed to raw water environment, for the following diesel engines: Insert D into page B-77 The baseline inspection portion of the Diesel Systems Inspection Program focuses on a representative sample population of subject components at susceptible locations to be defined in the implementing documents. The inspections identify symptomatic evidence of loss of material or cracking at other susceptible locations within the scope of the inspection due to the similarities in materials and environmental conditions. Subsequent inspections are opportunistic when components are opened for periodic maintenance, repair, and surveillance activities when surfaces are made available for inspection.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-78' The Diesel Systems Inspection Program does not include any actions to prevent aging effects or to mitigate aging degradation. This program is a condition monitoring program. Insert B into page B-78 The parameters to be inspected, by the Diesel Systems Inspection Program include wall thickness or visual evidence of internal surface degradation of the diesel exhaust piping as measures of loss of material and cracking. Inspections will be performed by qualified personnel using the appropriate established nondestructive examination (NDE) techniques, primarily visual, with enhanced visual, surface, or volumetric techniques used depending on the aging effect. Insert C into pare B-78 The Diesel Systems Inspection Program provides for detection of aging effects prior to a loss of component intended function. Inspections will include a combination of established visual or enhanced visual (e.g., VT-1 or VT-3 or equivalent), volumetric (e.g., radiographic testing or ultrasonic testing), and surface examination techniques performed by qualified personnel. Baseline inspections will be established on a sample population of subject components determined by engineering evaluation to identify evidence of loss of material or cracking prior to the period of extended operation. Opportunistic inspections will be conducted, thereafter, when components are opened for periodic maintenance, repair, or surveillance activities and surfaces are made available for inspection. For baseline inspections, the sample population will be 20% of the total population for each material - environment - aging effect group, up to a maximum of 25 inspections per group and, where practical, will be focused on the components most susceptible to aging, such as due to their time in service, the severity of conditions during normal plant operation, and the lowest design margins. Inspection of the sample population will be conducted within the 10-year period prior to the period of extended operation, and will serve as a baseline for future inspections. Any evidence of degradation that could lead to a loss of component intended function will be documented and evaluated through the Columbia corrective action program, including provisions for increasing the inspection sample size and locations. Aging Management Programs Page 13-78a Amendment 21
Columbia Generating Station License Renewal Application Technical Information Insert D into page B-78 The Diesel Systems Inspection Program comprises baseline inspections prior to the period of extended operation and opportunistic inspections when components are opened for maintenance, repair, or surveillance thereafter. Baseline inspections are used to characterize material conditions and include provisions for increasing the inspection sample size and locations if degradation is detected. The results of baseline inspections are considered to ensure that opportunistic inspections thereafter will detect aging prior to a loss of component intended function. The sample size for baseline inspections will be determined by engineering evaluation of the materials of construction, the environment (i.e., service conditions), aging effects, and of operating experience (e.g., time in-service, most susceptible locations, lowest design margins, etc.). Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program. Inspection findings will be documented and evaluated by assigned engineering personnel. The inspection findings will be reviewed to ensure that each material exposed to air-outdoor and raw water has been examined via opportunistic inspections within a 5 year time period. If opportunistic inspections have not occurred within the 5-year interval, appropriate actions will be taken to ensure these inspections are performed. Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program with subsequent adjustments to the program made as necessary.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-79 Indications or relevant conditions of degradation detected during the inspection will be compared to pre-determined acceptance criteria established by engineering evaluation of the pertinent design standard. Unacceptable inspection findings will include visual evidence of loss of material or cracking, or a reduction in wall thickness where appropriate, obtained by enhanced visual, surface, or volumetric examination. If the acceptance criteria are not met, then the indications and conditions will be evaluated under the Columbia corrective action program to determine whether they could result in a loss of component intended function during the period of extended operation or prior to the next opportunity for inspection. Insert B into pa-qe B-79 The Diesel Systems Inspection Program is a new plant-specific program for which plant operating experience has not shown the occurrence of the aforementioned aging effect. The program provides for confirmation of material conditions before entering the period of extended operation, and detection of aging effects prior to loss of component intended function during the period of extended operation. The elements comprising the program activities will be consistent with industry practice. Recent industry operating experience has been reviewed for applicability with only general indication that inspection of internal surfaces during the performance of periodic surveillance and maintenance activities has proven effective in maintaining the material condition of plant systems, structures, and components. Future operating experience is captured through the normal operating experience review process, which will continue through the period of extended operation. A review of Columbia operating experience to date has found no indications of loss of material or cracking in the subject diesel system components. This operating experience supports that baseline inspections of each material, to determine actual material conditions, prior to the period of extended operation and opportunistic inspections thereafter will, in conjunction with the normal operating experience review process, ensure aging is, detected prior to a loss of component intended function. The site corrective action program and an ongoing review of industry operating experience will be used to ensure that the program is effective in managing the effects of aging for components within the scope of this program during the period of extended operation.

Columbia Generating Station License Renewal Application Technical Information Insert A into pa-qe B-81 The Diesel-Driven Fire Pumps Inspection Program is a new plant-specific program for Columbia. The program will consist of inspections of the interior of the Fire Protection (FP) System diesel engine exhaust piping, and of FP System diesel heat exchangers exposed to a raw water (antifreeze or fire water) environment. The Diesel-Driven Fire Pumps Inspection Program will manage the effects of loss of material and reduction in heat transfer. The program also manages cracking due to stress corrosion cracking of susceptible materials. The Diesel-Driven Fire Pumps Inspection Program will comprise baseline inspections prior to the period of extended operation followed by opportunistic inspections, when components are opened for maintenance, repair, or surveillance to ensure that the existing environmental conditions in subject components are not causing material degradation that could result in a loss of component intended function during the period of extended operation. Implementation of this program will ensure that the pressure boundary and heat transfer capability of susceptible components is maintained consistent with the current licensing basis during the period of extended operation. The Diesel-Driven Fire Pumps Inspection Program is a new condition-monitoring program. Inspection of a sample population will be conducted within the 10-year period. prior to the period of extended operation and will serve as a baseline for future inspections. Insert B into page B-81 The Diesel-Driven Fire Pumps Inspection Program is a new plant-specific Columbia program for License Renewal. NUREG-1801 includes an Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program (XI.M38) that is focused on steel components and the loss of material aging effect. Rather than necessitating enhancements and exceptions to the NUREG-1801 program, a plant-specific program is credited. The Diesel-Driven Fire Pumps Inspection Program is a new plant-specific program that is evaluated against the ten elements described in Appendix A of the Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants, NUREG-1800, Revision 1.

Columbia Generating Station License Renewal Application Technical Information Insert C into pagqe B-81 Prior to the period of extended operation, the Diesel-Driven Fire Pumps Inspection Program includes a baseline inspection of a sample population followed by opportunistic inspection of the steel exhaust lines that are exposed to an air-outdoor environment and copper alloy, copper alloy > 15% Zn, gray cast iron, and stainless steel heat exchanger components exposed to a raw water (antifreeze or fire water) environment for the following diesels: Insert D into pa-qe B-81 The baseline inspection portion of Diesel-Driven Fire Pumps Inspection Program focuses on a representative sample population of subject components at susceptible locations to be defined in the implementing documents. The inspections identify symptomatic evidence of cracking, loss of material, or reduction in heat transfer at other susceptible locations within the scope of the inspection due to the similarities in materials and environmental conditions. Subsequent inspections are opportunistic when components are opened for periodic maintenance, repair, and surveillance activities when surfaces are made available for inspection.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-82 The parameters to be inspected by the Diesel-Driven Fire Pumps Inspection Program include wall thickness or visual evidence of internal surface degradation, of the diesel exhaust piping and heat exchangers as measures of cracking, loss of material, or reduction in heat transfer. Inspections will be performed by qualified personnel using the appropriate established nondestructive examination (NDE) techniques, primarily visual, with enhanced visual, surface, or volumetric techniques used depending on the aging effect. Insert B into pape B-82 The Diesel-Driven Fire Pumps Inspection Program provides for detection of aging effects prior to a loss of component intended function. Inspections will include a combination of established visual or enhanced visual (e.g., VT-1 or VT-3 or equivalent), volumetric (e.g., radiographic testing or ultrasonic testing), and surface examination techniques performed by qualified personnel. Baseline inspections will be established on a sample population of subject components determined by engineering evaluation to identify evidence of cracking, loss of material, or fouling, prior to the period of extended operation. Opportunistic inspections will be conducted, thereafter, when components are opened for maintenance, repair, or surveillance and surfaces are made available for inspection. For baseline inspections, the sample population will be 20% of the total population for each material - environment - aging effect group, up to a maximum of 25 inspections per group and, where practical, will be focused on the components most susceptible to aging, such as due to their time in service, the severity of conditions during normal plant operation, and the lowest design margins. Inspection of the sample population will be conducted within the 10 year period prior to the period of extended operation, and will serve as a baseline for future inspections. Any evidence~of degradation that could lead to a loss of component intended function will be documented and evaluated through the Columbia corrective action program, including provisions for increasing the inspection sample size and locations. Aging Management Programs Page B-82a Amendment 21
Columbia Generating Station License Renewal Application Technical Information Insert C into page B-82 The Diesel-Driven Fire Pumps Inspection Program comprises inspections prior to the period of extended operation and opportunistic inspections when components are opened for maintenance, repair, and surveillance thereafter. Baseline inspections are used to characterize material conditions and include provisions for increasing the inspection sample size and locations if degradation is detected. The results of baseline inspections are considered to ensure that opportunistic inspections thereafter will detect aging prior to a loss of component intended function. The sample size for baseline inspections will be determined by engineering evaluation of the materials of construction, the environment (i.e., service conditions), aging effects, and of operating experience (e.g., time in-service, most susceptible locations, lowest design margins, etc.). Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program. Inspection findings will be documented and evaluated by assigned engineering personnel. The inspection findings will be reviewed to ensure that each material exposed to air-outdoor and raw water has been examined via opportunistic inspections within a 5 year time period. If opportunistic inspections have not occurred within the 5 year interval, appropriate actions will be taken to ensure these inspections are performed. Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program with subsequent adjustments to the program made as necessary. Insert D into page B-82 Indications or relevant conditions of degradation detected during the inspection will be compared to pre-determined acceptance criteria established by engineering evaluation of the pertinent design standard. Unacceptable inspection findings will include visual evidence of cracking, loss of material, reduction in heat transfer due to fouling, or a reduction in wall thickness where appropriate, obtained by enhanced visual, surface, or volumetric examination. If the acceptance criteria are not met, then the indications and conditions will be evaluated under the Columbia corrective action program to determine whether they could result in a loss of component intended function during the period of extended operation or prior to the next opportunity for inspection.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-83 The Diesel-Driven Fire Pumps Inspection Program is a new plant-specific program for which plant operating experience has not shown the occurrence of the aforementioned aging effects. The program provides confirmation of material conditions before entering the period of extended operation, and detection of aging effects prior to loss of component intended function during the period of extended operation. The elements comprising the program activities will be consistent with industry practice. Recent industry operating experience has been reviewed for applicability; with only general indication that inspection of internal surfaces during the performance of periodic surveillance and maintenance activities has proven effective in maintaining the material condition of plant systems, structures, and components. Future operating experience is captured through the normal operating experience review process, which will continue through the period of extended operation. A review of Columbia operating experience reveals past issues associated with the subject components, including a loose clamp, a small oil leak, discolored oil, and a damaged connection pipe. None of these issues are age-related, nor do they involve the subject exhaust piping or heat exchanger components. This operating experience supports that baseline inspections of each material, to determine actual material conditions, prior to the period of extended operation and opportunistic inspections thereafter will, in conjunction with the normal operating experience review process, ensure aging is detected prior to a loss of component intended function. The site corrective action program and an ongoing review of industry operating experience will be used to ensure that the program is effective in managing the effects of aging for components within the scope of this program during the period of extended operation.

Columbia Generating Station License Renewal Application Technical Information due to crevice and pitting corrosion through examination of stainless steel and copper alloy piping components. Copper alloys with less than 15% zinc and less than 8% aluminum are not: susceptible to loss of material due to pitting or crevice corrosion and thus have no aging effect requiring management. 3.2.2.2.3.5 Partially Encased Tanks - Raw Water As stated in Table 3.2.1, there are no tanks at Columbia that compare to item number 3.2.1-07. The ESF systems contain no outdoor stainless steel tanks. Therefore, no further evaluation is necessary. 3.2.2.2.3.6 Piping, Piping Components, Piping Elements, and Tanks - Internal Condensation This item is applied to external condensation on stainless steel valve bodies in the RHR System. The resulting loss of material is managed by the External Surfaces Monitoring Program, which consists of observation and surveillance activities to detect age-related degradation. 3.2.2.2.4 Reduction of Heat Transfer due to Fouling 3.2.2.2.4.1 Heat Exchanger Tubes - Lubricating Oil Reduction of heat transfer for stainless steel and copper alloy heat exchanger tubes exposed to lubricating oil is managed by the Lubricating Oil Analysis Program. The Lubricating Oil Analysis Program manages aging effects through periodic monitoring and control of contaminants, including water. The Lubricating Oil Inspection will provide a verification of the effectiveness of the Lubricating Oil Analysis Program to manage reduction of heat transfer through examination of stainless steel and copper alloy heat exchanger tubes. 3.2.2.2.4.2 Heat Exchanger Tubes - Treated Water Reduction of heat transfer due to fouling for stainless steel heat exchanger tubes exposed to treated water in ESF systems is managed by the BWR Water Chemistry Program.

A.1.2.28 Flow-Accelerated Corrosion (FAC) Program The Flow-Accelerated Corrosion (FAC) Program manages loss of material for steel and gray cast iron components located in the treated water environment of systems that are susceptible to FAC, also called erosion-corrosion. The FAC Program combines the elements of predictive analysis, inspections (to baseline and monitor wall-thinning), industry experience, station information gathering and communication, and engineering judgment to monitor and predict FAC wear rates. The program is a condition monitoring program that implements the recommendations of NRC Generic Letter 89-08, and follows the guidance and recommendations of EPRI NSAC-202L [Reference A.1.4-2], to ensure that the integrity of piping systems susceptible to FAC is maintained. The FAC Program is an existing program that requires enhancement prior to the period of extended operation. A.1.2.29 Fuel Oil Chemistry Program The Fuel Oil Chemistry Program is an existing program that maintains fuel oil quality in order to mitigate degradation of the storage tanks and associated components containing fuel oil that are within the scope of license renewal. The program includes diesel fuel oil testing for emergency diesel generator and diesel-driven fire pump fuel. The Fuel Oil Chemistry Program manages the relevant conditions that could lead to the onset and propagation of loss of material due to corrosion, or cracking due to SCC of susceptible copper alloys, through proper monitoring and control of fuel oil contamination consistent with plant technical specifications and American Society for Testing and Materials (ASTM) standards for fuel oil.

.,,zz;L. ,e,,r~,, n z"in HVAC systems The External Surfaces Monitoring Program is a'.condition monitorinrg program that:
consists of visual inspections and'surveillance activities of accessible external surfaces on a frequency 'that generally exceeds once per fuel cycle.. Surfaces 'that are inaccessible during normal plant operation are inspected during refueling outages. Surfaces that are inaccessible or not readily .visible. during both plan0toperations and refueling outages, such as surfaces that are insulated, are inspected opportunistically, for example during maintenance activities during which insulation is removed. The External Surfaces Monitoring Program is supplemented by the Aboveground Steel' Tanks Inspection to manage loss of material for the inaccessible external surfaces of the carbon steel condensate storage.tanks (i.e., the tank bottom). NUREG-1801 Consistency The External Surfaces Monitoring Program is an existing Columbia program that, ýwith enhancement, will be consistent with the 10 elements of an effective aging management program as described in NUREG-1801, Section XI.M36, "External Surfaces; Monitorihg."

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-1 15 The Flexible Connection Inspection Program is a new plant-specific program for Columbia. The program will consist of inspections of elastomer components that are exposed to treated water, dried air, gas, and indoor air environments. The Flexible Connection Inspection Program will manage degradation of elastomer components, including the effects of loss of material due to wear and hardening and loss of strength due to thermal exposure and ionizing radiation. The Flexible Connection Inspection Program will comprise baseline inspections prior to the period of extended operation followed by opportunistic inspections, when components are opened for maintenance, repair, or surveillance, to ensure that the existing environmental conditions in subject components are not causing material degradation that could result in a loss of component intended function during the period of extended operation. Insert B into page B-115 Implementation of the program will also provide assurance (and confirmation) that the structural integrity of susceptible nonsafety-related components will be maintained such that spatial interactions, (e.g., leakage) will not result in the loss of any safety-related component intended functions during the period of extended operation. The Flexible Connection Inspection Program is a new condition-monitoring program. Inspection of a sample population will be conducted within the 10-year period prior to the period of extended operation and will serve as a baseline for future inspections. Insert C into pagqe B-1 15 The Flexible Connection Inspection Program is a new plant-specific Columbia program for License Renewal. NUREG-1801 includes an Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program (XI.M38) that is focused on steel components and the loss of material aging effect. Rather than necessitating enhancements and exceptions to the NUREG-1801 program, a plant-specific program is credited. The Flexible Connection Inspection Program is a new plant-specific program that is evaluated against the ten elements described in Appendix A of the Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants, NUREG-1800, Revision 1. The results of an evaluation for each element are provided below. Amendment 21 Aging Management Aging Programs Management Programs Page B-115a Page B-1 15a Amendment 21
Columbia Generating Station License Renewal Application Technical Information Insert D into pagqe B-115 Prior to the period of extended operation, the Flexible Connection Inspection Program identifies conditions relative to the following subject mechanical components to determine whether, and to what extent, degradation is occurring and to provide a baseline for future inspections. The scope of the Flexible Connection Inspection Program includes the surfaces of elastomer flexible connections exposed to treated water, dried air, gas, and indoor air environments in the following systems.
" Containment Exhaust Purge (CEP) " Containment Supply Purge (CSP) " Diesel Building HVAC " Diesel Cooling Water (DCW) " Diesel Fuel Oil (DO) " Fire Protection (FP)
- Pump House HVAC
" Radwaste Building HVAC
- Reactor Building HVAC
- Standby Gas Treatment (SGT)
The baseline inspection portion of Flexible Connection Inspection Program focuses on a representative sample population of subject components at susceptible locations to be defined in the implementing documents, to include internal and external surfaces of flexible connections exposed to treated water, dried air, gas, and indoor air environments. The inspections performed will be used to provide symptomatic evidence of loss of material due to wear and hardening and loss of strength at the other susceptible, but possibly inaccessible, locations due to the similarities in materials and environmental conditions. Subsequent inspections are opportunistic when components are opened for periodic maintenance, repair, and surveillance activities when surfaces are made available for inspection.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-1 16 Inspections will be performed by qualified personnel using the appropriate established nondestructive examination techniques, primarily visual and augmented by physical manipulation or prodding. Insert B into page B-116 The Flexible Connection Inspection Program provides for detection of aging effects prior to a loss of component intended function. Inspections will include a combination of visual and physical manipulation performed by qualified personnel. Baseline inspections will be established on a sample population of subject components determined by engineering evaluation to identify evidence of loss of material due to wear and hardening and loss of strength due to thermal exposure and ionizing radiation prior to the period of extended operation. Opportunistic inspections will be conducted, thereafter, when components are opened for maintenance, repair, or surveillance and surfaces are made available for inspection. For baseline inspections, the sample population will be 20% of the total population for each material - environment - aging effect group, up to a maximum of 25 inspections per group and, where practical, will be focused on the components most susceptible to aging, such as due to their time in service, the severity of conditions during normal plant operation, and the lowest design margins. Inspection of the sample population will be conducted within the 10-year period prior to the period of extended operation, and will serve as a baseline for future inspections. Any evidence of degradation that could lead to a loss of component intended function will be documented and evaluated through the Columbia corrective action program, including provisions for increasing the inspection sample size and locations.

Columbia Generating Station License Renewal Application Technical Information Insert C into pa-qe B-116 The Flexible Connection Inspection Program comprises baseline inspections prior to the period of extended operation and opportunistic inspections when components are opened for maintenance, repair, or surveillance thereafter. Baseline inspections are used to characterize material conditions and include provisions for increasing the inspection sample size and locations if degradation is detected. The results of baseline inspections are considered to ensure that opportunistic inspections thereafter will detect aging prior to a loss of component intended function. The sample size for baseline inspections will be determined by engineering evaluation of the materials of construction, the environment (i.e., service conditions), aging effects, and operating experience (e.g., time in-service, most susceptible locations, lowest design margins, etc.). Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program. Inspection findings will be documented and evaluated by assigned engineering personnel. The inspection findings will be reviewed to ensure that each material-environment has been examined via opportunistic inspection within a 5 year time period. If opportunistic inspections have not occurred within the 5-year interval, appropriate actions will be taken to ensure these inspections are performed. Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program with subsequent adjustments to the program made as necessary. Insert D into pagqe B-116 Indications or relevant conditions of degradation detected during the inspection will be compared to pre-determined acceptance criteria established by engineering evaluation of the pertinent design standard. Unacceptable inspection findings will include visual evidence of surface degradation, such as cracking or discoloration, as well as physical manipulation and prodding, as measures of loss of material due to wear and hardening and loss of strength that could lead to a loss of component intended function during the period of extended operation. If the acceptance criteria are not met, then the indications and conditions will be evaluated under the corrective action program to determine whether they could result in a loss of component intended function during the period of extended operation or prior to the next opportunity for inspection.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-1 17 The Flexible Connection Inspection Program is a new plant-specific program for which plant operating experience has not shown the occurrence of the aforementioned aging effects, with the exception of loss of material due to wear, which will also be managed by this program. As discussed below, tears were found in the HVAC boots, but no other flexible connections showed evidence of wear. The program provides confirmation of material conditions before entering the period of extended operation, and detection of aging effects prior to loss of component intended function during the period of extended operation. The elements comprising the program are to be consistent with industry practice. Insert B into page B-117 with only general indication that inspection of internal surfaces during the performance of periodic surveillance and maintenance activities has proven effective in maintaining the material condition of plant systems, structures, and components. Insert C into page B-117 Because of this operating experience, loss of material due to wear will also be managed by this program. Insert D into page B-117 This operating experience supports that baseline inspections, to determine actual material conditions, prior to the period of extended operation and opportunistic inspections thereafter will, in conjunction with the normal operating experience review process, ensure aging is detected prior to a loss of component intended function. The site corrective action program and an ongoing review of industry operating experience will be used to ensure that component intended functions will be maintained during the period of extended operation.

Columbia Generating Station License Renewal Application Technical Information Insert A into paaqe A-22 The Monitoring and Collection Systems Inspection Program manages the effects of loss of material due to corrosion or erosion for the internal surfaces of subject mechanical components that are exposed to equipment or area drainage water and other potential contaminants and fluids. The program also manages cracking due to stress corrosion cracking of susceptible materials. The Monitoring and Collection Systems Inspection Program is a new program that will be implemented via baseline inspection of a sample population followed by opportunistic inspections when components are opened for periodic maintenance, repair, and surveillance activities when surfaces are made available for inspection. These inspections ensure that the existing environmental conditions are not causing material degradation that could result in a loss of component intended function during the period of extended operation. Inspection of a sample population will be conducted within the 10-year period prior to the period of extended operation and will serve as a baseline for future inspections.

Columbia Generating Station License Renewal Application Technical Information Insert A into pagqe A-57 The Monitoring and Collection Systems Inspection Program is a new program. The Monitoring and Collection Systems Inspection Program manages the effects of loss of material due to corrosion or erosion for the internal surfaces of subject mechanical components that are exposed to equipment or area drainage water and other potential contaminants and fluids. The program also manages cracking due to stress corrosion cracking of susceptible materials. The program consists of baseline inspections prior to the period of extended operation followed by opportunistic inspections during the period of extended operation. Following the baseline inspection, inspection findings will be reviewed periodically to ensure that each material and environment combination has been examined via opportunistic inspection or actions are taken to ensure inspections are performed. Initial interval for review of inspection findings is 5 years and may be adjusted based on operating experience.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-159 The Monitoring and Collection Systems Inspection Program is a new plant-specific program for Columbia. The program will consist of inspections of subject mechanical components that are exposed to equipment and area drainage water and other potential contaminants and fluids. The Monitoring and Collection Systems Inspection Program will manage the effects of loss of material due to crevice, galvanic, general, or pitting corrosion, erosion, or microbiologically-influenced corrosion (MIC). The program will also manage the effects of cracking due to stress corrosion cracking (SCC) of susceptible materials in susceptible locations. The Monitoring and Collection Systems Inspection Program will comprise baseline inspections prior to the period of extended operation followed by opportunistic inspections, when components are opened for maintenance, repair, or surveillance, to ensure that the existing environmental conditions in subject components are not causing material degradation that could result in a loss of component intended function during the period of extended operation. Insert B into page B-159 The Monitoring and Collection Systems Inspection Program is a new condition-monitoring program. Inspection of a sample population will be conducted within the 10-year period prior to the period of extended operation and will serve as a baseline for future inspections. Insert C into page B-159 The Monitoring and Collection Systems Inspection Program is a new plant-specific program for Columbia for License Renewal. NUREG-1801 includes an Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program (XI.M38) that is focused on steel components and the loss of material aging effect. Rather than necessitating enhancements and exceptions to the NUREG-1801 program, a plant-specific program is credited. The Monitoring and Collection Systems Inspection Program is a new plant-specific program that is evaluated against the ten elements described in Appendix A of the Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants, NUREG-1800, Revision 1.

Columbia Generating Station License Renewal Application Technical Information Insert D into page B-160 The Monitoring and Collection Systems Inspection Program provides for detection of aging effects prior to a loss of component intended function. Inspections will include a combination of established visual or enhanced visual (e.g., VT'-I or VT-3 or equivalent), volumetric (e.g., radiographic testing or ultrasonic testing), and surface examination techniques performed by qualified personnel. Baseline inspections will be established on a sample population of subject components determined by engineering evaluation to identify evidence of cracking or loss of material prior to the period of extended operation. Opportunistic inspections will be conducted, thereafter, when components are opened for maintenance, repair, or surveillance, and surfaces are available for inspection. For baseline inspections, the sample population will be 20% of the total population for each material - environment - aging effect group, up to a maximum of 25 inspections per group, and, where practical, will be focused on the components most susceptible to aging, such as due to their time in service, the severity of conditions during normal plant operations, and the lowest design margins. Inspection of the sample population will be conducted within the 10-year period prior to the period of extended operation, and will serve as a baseline for future inspections. Any evidence of degradation that could lead to a loss of component intended function will be documented and evaluated through the Columbia corrective action program, including provisions for increasing the inspection sample size and locations.

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-161 The Monitoring and Collection Systems Inspection Program comprises baseline inspections prior to the period of extended operation and opportunistic inspections when components are opened for maintenance, repair, or surveillance thereafter. Baseline inspections are used to characterize material conditions and include provisions for increasing the inspection sample size and locations if degradation is detected. The results of baseline inspections are considered to ensure that opportunistic inspections thereafter will detect aging prior to a loss of component intended function. The sample population for baseline inspections will be determined by engineering evaluation of the materials of construction, the environment (i.e., service conditions), aging effects, and of operating experience (e.g., time in-service, most susceptible locations, lowest design margins, etc.). Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program. Inspection findings will be documented and evaluated by assigned engineering personnel. The inspection findings will be reviewed to ensure that each material and environment combination has been examined via opportunistic inspection within a 5 year time period. If opportunistic inspections have not occurred within the 5-year interval, appropriate actions will be taken to ensure these inspections are performed. Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program, with subsequent adjustments to the program made as necessary. Insert B into page B-161 Indications or relevant conditions of degradation detected during the inspection will be compared to pre-determined acceptance criteria established by engineering evaluation of the pertinent design standard. Unacceptable inspection, findings will include visual evidence of a loss of material, a reduction in wall thickness where appropriate, or evidence of cracking obtained by enhanced visual, surface, or volumetric examination. If the acceptance criteria are not met, then the indications and conditions will be evaluated'under the Columbia corrective action program to determine whether they could result in a loss of component intended function during the period of extended operation or prior to the next opportunity for inspection.

Columbia Generating Station License Renewal Application Technical Information Energy Northwest follows the requirements of the BWRVIP ISP and applies the ISP data to Columbia. The NRC has approved the use of the BWRVIP ISP in place of a unique plant program for Columbia. The provisions of 10 CFR50 Appendix G require Columbia to operate within the currently licensed pressure-temperature (P-T) limit curves, and to update these curves as necessary. The P-T limit curves, as contained in plant technical specifications, will be updated as necessary through the period of extended operation as part of the Reactor Vessel Surveillance Program.

This periodic program will provide physical evidence as to whether, and to what extent, cracking due to SCC or to thermal or mechanical loading has occurred in small bore Class 1 piping components. It will also verify, by inspections for cracking, that reduction of fracture toughness due to thermal embrittlement requires no additional aging management for small Class 1 cast austenitic stainless steel valve bodies. The Small Bore Class 1 Piping Program will be a condition monitoring program with no actions to prevent or mitigate aging effects. The program will include visual and volumetric inspection of a representative sample of small bore Class 1 piping, including butt welds and socket welds. The Small Bore Class 1 Piping Program is a new program that will be implemented prior to the period of extended operation. Inspection activities will start during the fourth 10-year inservice inspection interval and continue through the period of extended operation. The Small Bore Class 1 Piping Program will credit portions of the Inservice Inspection Program. The Small Bore Class 1 Piping Program will verify the effectiveness of the BWR Water Chemistry Program in mitigating cracking of small bore piping and piping components. Insert B into page A-24 The Service Air System Inspection Program manages the effect of loss of material due to corrosion of steel piping and valve bodies exposed to an "air (internal)" (i.e., compressed air) environment within the license renewal boundary of the Service Air System. The Service Air System Inspection Program is a new plant-specific program that will be implemented via baseline inspection of a sample population followed by opportunistic inspections when components are opened for periodic maintenance, repair, or surveillances when surfaces are made available for inspection. These inspections ensure that the existing environmental conditions are not causing material degradation that could result in a loss of component intended function during the period of extended operation. Inspection of a sample population will be conducted within the 10-year period prior to the period of extended operation and will serve as a baseline for future inspections.

Opportunistic inspections will be conducted, thereafter, when components are opened for maintenance, repair, or surveillance and surfaces are made available for inspection. For baseline inspections, the sample population will be 20% of the total population for each material - environment - aging effect group, up to a maximum of 25 inspections per group and, where practical, will be focused on the components most susceptible to aging, such as due to their time in service, the severity of conditions during normal plant operation, and the lowest design margins. Inspection of the sample population will be conducted within the 10-year period prior to the period of extended operation, and will serve as a baseline for future inspections. Any evidence of degradation that could lead to a loss of component intended function will be documented and evaluated through the C6lumbia corrective action program, including provisions for increasing the inspection sample size and locations.

Columbia Generating Station License Renewal Application Technical Information Insert C into pagqe B-184 The Service Air System Inspection Program comprises baseline inspections prior to the period of extended operation and opportunistic inspections when components are opened for maintenance, repair, or surveillance thereafter. Baseline inspections are used to characterize material conditions and include provisions for increasing the inspection sample size and locations if degradation is detected. The results of baseline inspections are considered to ensure that opportunistic inspections thereafter will detect aging prior to a loss of component intended function. Sample size for baseline inspections will be determined by engineering evaluation of the materials of construction, environment (i.e., service conditions), aging effects, and operating experience (e.g., time in-service, most susceptible locations, lowest design margins). Inspection findings that do not meet the acceptance criteria will be evaluated using the corrective action program. Inspection findings will be documented and evaluated by assigned engineering personnel. The inspection findings will be reviewed to ensure that each material has been examined via opportunistic inspection within a 5 year time period. If opportunistic inspections have not occurred within the 5-year interval, appropriate actions will be taken to ensure these inspections are performed. Inspection findings that do not meet the acceptance criteria will be evaluated using the Columbia corrective action program with subsequent adjustments to the program made as necessary. Insert D into pagqe B-184 Indications or relevant conditions of degradation detected during the inspections will be compared to pre-determined acceptance criteria established by engineering evaluation of the pertinent design standard. Unacceptable inspection findings will include visual evidence of loss of material or reduction in wall thickeness, where appropriate, that could lead to a loss of component intended function during the period of extended operation. If the acceptance criteria are not met, then the indications and conditions will be evaluated under the Columbia corrective action program to determine whether they could result in a loss of component intended function during the period of extended operation or prior to the next opportunity for inspection. 0 Aging Management Programs Page 13-184b Amendment 21

Columbia Generating Station License Renewal Application Technical Information Insert A into page B-185 The Service Air System Inspection Program is a new plant-specific program for which plant operating experience has not shown the occurrence of the aforementioned aging effect. Due to the fact that portable compressors without dryers have been used in the Service Air System, the system may not have always been reliably dry. The ".speetie-provides confirmation of material conditions before entering the period of extendedP operation, and detection of aging effects prior to loss of component intended function during the period of extended operation. The elements comprising the program are to be consistent with industry practice. NUREG-1801, Revision 1, is based on industry operating experience through January 2005. Recent industry operating experience has been reviewed for applicability, with only a general indication that inspection of internal surfaces during the performance of periodic surveillance and maintenance activities has proven effective in maintaining the material condition of plant systems, structures, and components. Future operating experience is captured through the normal plant operating experience review process, which will continue through the period of extended operation. This operating experience supports that baseline inspections of each material, to determine actual material conditions, prior to the period of extended operation and opportunistic inspections thereafter will, in conjunction with the normal operating experience review process, ensure aging is detected prior to a loss of component intended function. The site corrective action program and an ongoing review of industry operating experience will be used to ensure that the program is effective in managing the effects of aging for components within the scope of this program during the period of extended operation.
