Sampling results indicate.a groundwater pH minimum value of 6.9, chloride content maximum value of 36 ppm, and sulfate content maximum value of 323 ppm.Primary Containment foundation concrete is designed in accordance with American Concrete Institute (ACI) 318-63 or 318-71 and constructed in accordance with ACI 301-66 or 301-72 using ingredients conforming to ACI and American Society for Testing and Materials (ASTM) standards. Concrete constructed to these criteria has a low water-to-cement ratio of less than 0.50 and an air entrainment between 3 and 6 percent and provides a good quality dense concrete with a low permeability, which meets the intent of ACI 201.2R-77. (Note: Columbia does not specify water-to-cement ratio, however for massive concrete (sections more than 30 inches in the least dimension) a minimum slump of 1 inch and a maximum slump of 3 inches is provided so that the average for all batches or of the most recent 10 batches tested, whichever is lower, does not exceed 2-1/2 inches. Water-to-cement ratio is established by tests of trial mixes using the materials and slump proposed for use. The slump working limit at point of placement specified in design specification yields concrete with low water-to-cement ratio since the average slump at the point of placement is less than the working limit, which is the maximum slump for estimating the quantity of mixing water to be used in the concrete.) The Primary Containment concrete is not exposed to an aggressive environment and the design and construction of the concrete is in accordance with accepted ACI Standards, thereby precluding aggressive chemical attack and embedded steel corrosion aging mechanisms. Therefore, increases in porosity and permeability, cracking, loss of material (spalling, scaling) due to aggressive chemical attack, and cracking, loss of bond, and loss of material (spalling, scaling) due to corrosion of embedded steel are not applicable for Primary Containment concrete in inaccessible areas.The absence of concrete aging effects is confirmed under the Structures Monitoring Program.

Foundations of all Columbia plant structures are supported on structural backfill. The backfill provides safe bearing for the structural foundations, and settlements are estimated to be minimal.In order to compare the calculated to actual settlement, measurement points were established at the corners of the substructure of the Reactor Building, Radwaste Qontrol Building, Spray Ponds, and along the four sides of the sub-structure of the Turbine Generator Building. These points have been monitored systematically since the beginning of construction. The settlement observation records to date for these facilities are included in the FSAR, Appendix 2.5H. The results of settlement monitoring program show that the actual maximum differential settlements are well within the estimated differential settlements and that they remain of no consequence to the design of plant structures appurtenances. The measured settlement rate in the time frame from 1986 to 1991 has virtually leveled off (i.e., zero settlement) for the, Reactor, Radwaste Control, and Turbine Generator buildings and was less than an average of 0.001 feet per year for both Spray Ponds. Therefore, commitments regarding settlement have been satisfied as any future settlements during the lifetime of the plant will not adversely affect the plant structures or appurtenances. Columbia does not employ a de-watering system in any of the site structures for control of settlement since the groundwater level at the site is sufficiently lower than the deepest foundation in the complex. The Primary Containment base foundation is not constructed of porous concrete below-grade and is not subject to flowing water.Therefore, cracks and distortion due to increased stress levels from settlement, and reduction of foundation strength, cracking, and differential settlement due to erosion of porous concrete are not applicable to the Primary Containment concrete subfoundations. 3.5.2.2.1.3 Reduction of Strength and Modulus of Concrete Structures due to Elevated Temperature ASME Code, Section III, Division 2, Subsection CC indicates that aging due to elevated temperature exposure is not significant as long as concrete general area temperatures do not exceed 150 OF and local area temperatures do not exceed 200 OF.

The sand filled pocket area is used to collect any drainage between the primary containment vessel exterior and the biological shield wall.An embedded steel closure ring is installed on the top of the sand filled transition area.Due to the possibility of containment shell degradation from corrosion induced by a moist environment in the sand pocket region, Columbia has committed to monitor humidity levels in this region.

Due to the possibility of containment shell degradation from corrosion induced by a moist environment in the sand pocket region, Columbia has committed to monitor humidity levels in this region. Columbia has implemented a procedure to survey the relative humidity of air drawn from within the containment annulus sand pocket region.

Concrete constructed to these criteria has a low water-to-cement ratio of less than 0.50 and an air entrainment between 3 and 6 percent and provides a good quality dense concrete with a low permeability, which meets the intent of ACI 201.2R-77. (Note: Columbia does not specify water-to-cement ratio, however for massive concrete (sections more than 30 inches in the least dimension) a minimum slump of 1 inch and a maximum slump of 3 inches is provided so that the average for all batches or of the most recent 10 batches tested, whichever is lower, does not exceed 2-1/2 inches. Water-to-cement ratio is established by tests of trial mixes using thematerials and slump proposed for use. The slump working limit at point of placement specified in design specification yields concrete with low water-to-cement ratio since the average slump at the point of placement is less than the working limit, which is the maximum slump for estimating the quantity of mixing water to be used in the concrete.) Columbia requires that concrete aggregates conform to ASTM C33 and that the potential reactivity of aggregates be acceptable based on testing in accordance with the Standard Test Method for Potential Alkali Reactivity of Cement-Aggregate Combinations (Mortar-Bar Method) (ASTM C227) or the Standard Test Method for Potential Alkali-Silica Reactivity of Aggregates (Chemical Method) (ASTM C289).Columbia specifications for concrete prohibit the use of calcium chloride in the concrete mix design.Leaching of calcium hydroxide from reinforced concrete becomes significant only if the concrete is exposed to flowing water. Seismic Category I structures and safety-related systems and components at Columbia are located above the present groundwater elevation 380 feet msl (mean sea level) and are not subject to any force effects of buoyancy and static water from this groundwater elevation. The bottom of the Reactor Building foundation mat is at elevation 400 feet 9 inches; therefore, foundation interaction with groundwater is unlikely. The Primary Containment concrete is not exposed to flowing water and the design and construction of the Primary Containment concrete is in accordance with accepted ACI Standards, thereby precluding expansion and reaction with aggregate and leaching of calcium hydroxide aging mechanisms.

Sampling results indicate a groundwater pH minimum value of 6.9, chloride content maximum value of 36 ppm, and sulfate content maximum value of 323 ppm.Raw water sampling results indicate a raw water pH minimum value of 6.6, chloride content maximum value of 60 ppm, and sulfate content maximum value of 127 ppm.Columbia concrete is designed in accordance with ACI 318-63 or 318-71 and constructed in accordance with ACI 301-66 or 301-72 using ingredients conforming to ACI and ASTM standards. Concrete constructed to these criteria has a low water-to-cement ratio of less than 0.50 and an air entrainment between 3 and 6 percent andprovides a good quality dense concrete with a low permeability, which meets the intent of ACI 201.2R-77. (Note: Columbia does not specify water-to-cement ratio, however for massive concrete (sections more than 30 inches in the least dimension) a minimum slump of 1 inch and a maximum slump-of 3 inches is provided so that the average for all batches or of the most recent 10 batches tested, whichever is lower, does not exceed 2-1/2 inches. Water-to-cement ratio is established by tests of trial mixes using the materials and slump proposed for use. The slump working limit at point of placement specified in design specification yields concrete with low water-to-cement ratio since the average slump at the point of placement is less than the working limit, which is the maximum slump for estimating the quantity of mixing water to be used in the concrete.)

Aging Management Review Results Page 3.5-137 January 2010 Columbia Generating Station License Renewal Application Technical Information Plant-Specific Notes: 0501 No applicable aging effects have been identified for the component type. However, the identified AMP will be used to confirm the absence of significant aging effects for the period of extended operation. 0502 NUREG-1801 item lI.B2.1-1 indicates the moisture barrier, at the junction where the shell or liner becomes embedded, is subject to aging management activities in accordance with ASME Section Xl, Subsection IWE requirements. Columbia drywell floor peripheral seal is made of stainless steel and is welded to the primary containment vessel and to the underside of the circular closure girder embedded in the drywell floor. There are no concrete to metal moisture barriers; therefore, the NUREG-1 801 textregarding moisture barrier is not applicable. 0503 The refueling stainless steel bellows perform their functions during refueling preventing water from entering the drywell. The bellows are not subjected to cyclic loading during refueling. The normal environment experienced by the refueling bellows is warm, dry air, with short periods of demineralized water contact during refueling. 0504 Due to possibility of containment shell degradation from corrosion induced by a moist environment in sand pocket region, Columbia has committed to monitor humidity levels in this region. Columbia has implemented a procedure to survey the relative humidity of air drawn from within containment annulus sand pocket region. k 0505 The process line penetrations are of welded steel construction without expansion bellows, gaskets, or sealing compounds. Electrical penetration assembly internal o-rings are sub-component of the electrical penetration and are included in this commodity group. Insulation for hot penetrations is addressed in bulk commodities. 0506 Elastomeric seals, gaskets, or o-rings are sub-part of the host component and their leak tightness is monitored by the Appendix JProgram.

Additional testing was performed, which resulted in developing a coating system that has proven effective in mitigating the flashover when reapplied at least every 10 years.Due to the operating experience with the 500-kV system, Columbia instituted a program to clean the high voltage insulators on the 115-kV system, identified for license renewal as the plant-specific High-Voltage Porcelain Insulators Aging Management Program, in order to manage the build-up of hard water residue from the cooling tower plume, and thereby mitigate potential degradation of the insulation function.

This program allows for the option to either hand clean the in-scope high voltage insulators every two years or to coat the insulators every 10 years and inspect the coating for damage every two years between coatings. The operating experience indicates that this is only an issue with station post insulators. There are no station post insulators associated with the 230-kV system in the Columbia transformer yard, therefore the 230-kV system is.excluded. Loss of material due to mechanical wear is an aging effect for certain strain insulators if they are subject to significant movement. Such movement of the insulators can be caused by wind blowing the supported transmission conductor, causing it to sway from side to side. If this swinging motion occurs frequently enough, it could cause wear on the metallic contact points of the insulator string and between an insulator and the supporting hardware. Although this aging mechanism is possible, industry experience has shown that transmission conductors do not normally swing unless subjected to a substantial wind, and they stop swinging shortly after the wind subsides. Wind loading that can result in conductor sway is considered in the transmission system design. For insulators that are associated with switchyard bus, movement is precluded by the rigid design of the switchyard bus (i.e., the bus is of short length, is rigid itself, and is connected to rigid components). Review of operating experience has identified no concerns related to the occurrence of loss of material due to mechanical wear as a result of wind blowing on transmission conductors and the switchyard high voltageinsulators. Therefore, loss of material due to mechanical wear is not an aging effect requiring management for the high voltage insulators at Columbia.3.6.2.2.3 Loss of Material due toWind Induced Abrasion and Fatigue, Loss ofConductor Strength due to Corrosion, and Increased Resistance of Connection due to Oxidation or Loss of Pre-LoadThe switchyard bus which connects Back-up Transformer E-TR-B to circuit breaker E-CB-TRB and the bus between the 230 kV overhead line and circuit breaker A809 is within the scope of license renewal at Columbia.

• Columbia Generating StationLicense Renewal Application Technical Information very thin surface layer of oxidation, but the tube itself does not oxidize and theconductor properties are not degraded by a thin surface oxidation layer. The Columbia applications incorporate the use of galvanized or stainless steel "Belleville" washers on bolted electrical connections using galvanized or stainless steel bolts, nuts, and washers to compensate for temperature changes and to maintain the proper tightness.

The bolted connections are exposed to the ambient service conditions in the switchyard bus locations at Columbia (in the plant transformer yard and in the Ashe substation), and do not experience any aging effects that require management. From EPRI. TR-104213 ("Bolted Joint Maintenance & Applications Guide"), Section 15.7.5.3, ANSI B18.21.1 ("Lock Washers") has not changed since 1972. Prior to that.year, it was designated ASA B27.1 (1965). The specification was changed in 1972regarding embrittlement. Prior to 1972, there was no statement made to prevent possible hydrogen embrittlement if the washers were plated. Because construction of the Columbia transformer yard post-dates 1972, there is strong assurance that the washers used at Columbia are not subject to hydrogen embrittlement. Wind-induced abrasion and fatigue are not aging effects applicable to the in-scopetransmission conductors. Industry experience has shown that transmission conductors do not normally swing unless subjected to substantial winds, and they stop swinging after a short period once the wind subsides. Because the transmission conductors are not normally moving, the loss of material due to wind-induced abrasion and fatigue is not an aging effect requiring management. Loss of conductor strength due to corrosion of the transmission conductor is not identified as an aging effect due to ample design margin and a minimal corrosion process at the rural location of Columbia. Connection resistance is not identified as a stressor based on use of good bolting practices and review of site operating experience. EPRI Report 1013475, the License Renewal Electrical Handbook, concludes that the most prevalent aging mechanism contributing to loss of conductor strength of ACSR (aluminum conductor steel reinforced) transmission conductors is corrosion. For ACSRconductors, degradation begins as a loss of zinc from the galvanized steel core wires.Corrosion rates depend largely on air quality, which involves suspended particles in the air, sulfur dioxide (SO 2) concentration, rain, fog chemistry, and other weather conditions. Corrosion of ACSR conductors is a very slow process that is even slower in rural areas with less air pollution. Columbia is located in a rural area in east-central Washington state, where airborne particle concentrations are low.Tests performed by Ontario Hydroelectric showed a 30 percent composite loss of conductor strength for an 80 year-old sample of an ACSR conductor (due to corrosion). The Ontario Hydroelectric Test Report is available from the Institute of Electrical and Electronics Engineers (IEEE). The report is documented in two parts in the IEEE Transactions on Power Delivery, Volume 7, Number 2, April 1992©.

The field testing involved detection of steel core galvanizing loss via the use of an overhead line conductor corrosion detector. Laboratory tests (using a dynamometer) were performed for fatigue, tensile strength, torsional ductility, and electrical performance. The report also addressed metallurgical data and analysis of potential environmental contributors. With respect to the Ontario Hydroelectric study, the National Electrical Safety Code (NESC) requires that tension on installed conductors be a maximum of 60 percent of the ultimate conductor strength and that consideration for ice, wind, and temperature be included in the design. The discussion in EPRI 1013475 demonstrates that with a 30 percent loss of conductor strength, there is still margin between the NESC requirements and the actual 'conductor strength. Because the Columbia transmission conductor design and installation meets the NESC requirements, the Ontario Hydroelectric study bounds the Columbia configuration. The specific comparisons are addressed below.The transmission conductors within the scope of license renewal are "Drake" ACSR 795 MCM (thousand circular mils) with a 26/7 stranding (for the 230-kV system). The Ontario Hydro testing included ACSR with the same stranding configuration as the Columbia transmission conductors. The Columbia transmission conductors have an ultimate strength of 31,200 pounds for the "Drake" configuration. The "Drake" conductor has a maximum design working tension of 8,000 pounds. Because the Ontario Hydro study demonstrated a 30 percent loss of ultimate strength in an 80 year-old conductor, the Columbia transmission conductors are shown to demonstrate the following: Normal margin (ultimate versus maximum design tension): "Drake" -(31,200 -8,000) / (31,200) = 0.74 x 100 = 74 percentAged margin (assuming a 30 percent loss of ultimate strength): ".Drake" -[(0.7)*(31,200) -8,000] [(31,200)*(0.7)] = 0.63 x 100 = 63 percent This demonstrates that (using the Ontario Hydroelectric test data) the Columbiatransmission conductors will have greater than 63 percent ultimate strength margin remaining after 80 years.Therefore, based on the expected low corrosion rates due to plant location and the margins included in the design, corrosion of the transmission conductors is not an aging effect requiring management for the period of extended operation. Increased connection resistance is not identified as an aging effect requiring management.

Aging Management Review Results Page 3.6,.27 January 2010 Columbia Generating Station License Renewal Application Technical Information Plant-Specific Notes: Loss of material due to wear is not an applicable aging effect for the in-scope high-voltage insulators at Columbia - see Section 3.6.2.2.2 for evaluation. 0602 For the switchyard bus and connections, no aging effects are identified that require aging management -refer to Section 3.6.2.2.3 for evaluation. A review of the Columbia fuse list and other engineering documents showed that there are no in-scope passive fuses that are pulled on a routine basis such that deformation (fatigue) would cause loosening of the fuse holder.The in-scope fuse holders at Columbia are located in metallic electrical boxes (terminal boxes) which have covers to protect the interior of the box from the ambient environment. The boxes are not exposed to weather conditions (they are located indoors); they are not exposed to chemical contamination or spills; they are not exposed to mechanical stress inside the box; and, due to the 0603 Columbia location in rural central Washington, they are not located in an evironment with industrial pollution or salt deposition. Therefore, chemical contamination, corrosion, and oxidation are not applicable aging mechanisms for the fuse holders within the license renewal scope at Columbia.With respect to electrical transients and ohmic heating, these fuses are not heavily loaded and do not experience frequent electrical and thermal cycling. With respect to vibration, it is an induced aging mechanism, and the fuse boxes are securely mounted on walls, so vibration itself is not an applicable stressor.The transmission conductors within the license renewal scope are those that connect start-up transformer E-TR-S to circuit breaker A 809 in the Ashe substation switchyard. This circuit breaker constitutes part of the station blackout license renewal boundary.0604 This segment of transmission conductor does not exhibit significant aging mechanisms or effects. An aging management program is not required for the segment of transmission conductor that is within the scope of license renewal. See Section 3.6.2.2.3 for details.The inspection of the metal-enclosed bus enclosure assembly elastomers (joints, seals, gaskets) will be performed as part of the Metal-Enclosed Bus Program. The elastomers will be inspected when the covers of the various bus enclosure sections are 0605 removed. The Structures Monitoring Program will address the metallic portion of the enclosure assembly and the external structural supports for the various bus assemblies (along with the building penetrations and seals where the bus ducts enter the Reactor Building). In addition to steel and galvanized steel, Columbia uses aluminum enclosures (a material not mentioned in NUREG-1801, Item 0606 VI.A-1 3). Note A is used, because the Structures Monitoring Program includes consideration of aluminum and is consistent with NUREG-1801. 0607 Inspection of a sample of the passive fuse boxes within the scope of license renewal (performed in September 2007) showed that conditions are clean and dry, with no corrosion or moisture intrusion found.Aging Management Review Results Page 3.6-28 January 2010 Columbia Generating Station License Renewal Application Technical Information Notes: 0601 Loss of material due to wear is not an applicable aging effect for the in-scope high-voltage insulators at Columbia -see Section 3.6.2.2.2 for evaluation. 0602 For the switchyard bus and connections, no aging effects are identified that require aging management -refer to Section 3.6.2.2.3 for evaluation. A review of the Columbia fuse list and other engineering documents showed that there are no in-scope passive fuses that are pulled on a routine basis such that deformation (fatigue) would cause loosening of the fuse holder. . The in-scope fuse holders at Columbia are located in metallic electrical boxes (terminal boxes) which have covers to protect the interior of the box from the ambient environment. The boxes are not exposed to weather conditions (they are located indoors); they are not exposed to chemical contamination or spills; they are not exposed to mechanical stress inside the box; and, due to the 0603 Columbia location in rural central Washington, they are not located in an evironment with industrial pollution or salt deposition. Therefore, chemical contamination, corrosion, and oxidation are not applicable aging mechanisms forthe fuse holders within the license renewal scope at Columbia. With respect to electrical transients and ohmic heating, these fuses are not heavily loaded and do not experience frequent electrical and thermal cycling. With respect to vibration, it is an induced aging mechanism, and the fuse boxes are securely mounted on* , walls, so vibration itself is not an applicable stressor. The transmission conductors within the license renewal scope are those that connect start-up transformer E-TR-S to circuit breaker A 809 in the Ashe substation switchyard. This circuit breaker constitutes part cif the station blackout license renewal boundary. 0604 This segment of transmission conductor does not exhibit significant aging mechanisms or effects. An aging management program is not required for the segment of transmission conductor that is within the scope of license renewal. See Section 3.6.2.2.3 for details. .. The inspection of the metal-enclosed bus enclosure assembly elastomers Ooints, seals, gaskets) will be performed as part of the Metal-Enclosed Bus Program. The elastomers will be inspected when the covers of the various bus enclosure sections are 0605 removed. The Structures Monitoring Program will address the metallic portion of the enclosure assembly and the external structural supports for the various bus assemblies (along with the building penetrations and seals where the bus ducts enter the Reactor Building).* . In addition to steel and galvanized steel, Columbia uses aluminum enclosures (a material not mentioned in NUREG-1801, Item 0606 VI.A-13).

• Columbia Generating StationLicense Renewal Application Technical Information 4.2 REACTOR VESSEL NEUTRON EMBRITTLEMENT Neutron embrittlement is the term used to describe changes-in mechanical properties of reactor vessel materials that result from exposure to fast neutron flux (E>1.0 MeV)within the beltline region.

The most pronounced material change is a reduction in fracture toughness. As fracture toughness decreases, with cumulative fast neutron exposure, the material's resistance to crack propagation decreases. Fracture toughness is also dependent on temperature. The reference temperature for nil-ductility transition (RTNDT) is the temperature above which the material behaves in a ductile manner and below which the material behaves in a brittle manner. As fluence increases, RTNDT increases. This means higher temperatures are required for the material to continue to act in a ductile manner.The regulations governing reactor vessel integrity are in 10 CFR Part 50. Section 50.60 requires that all light-water reactors meet the fracture toughness, pressure-temperature limits, and material surveillance program requirements for the reactor coolant pressure boundary as set forth in Appendices G and H of 10 CFR 50.The analyses associated with evaluation of the effect of neutron embrittlement on the Columbia reactor pressure vessel for 40 years are TLAAs. Neutron fluence, Upper shelf energy (USE), adjusted reference temperature (ART), and vessel pressure-temperature (P-T) limits are time dependent parameters that must be investigated with respect to fracture toughness (embrittlement) of reactor vessel materials. The following sections address fluence, USE, ART, P-T limits, circumferential welds, and axial welds for the reactor pressure vessel (RPV) beltline materials for the period of extended operation. This discussion uses the latest data, as submitted to the NRC on June 9, 2004 (Reference 4.8-1) and approved by the NRC in license amendment'number 193 on May 12, 2005 (Reference 4.8-2). The latest data supersedes the information currently in the NRC's Reactor Vessel Integrity Database (RVID2).4.2.1 Neutron Fluence EFPY Projection To evaluate the effects of radiation on RPV material embrittlement, the results of analyses were projected to determine neutron fluence out to 54 effective full power years (EFPY). Using actual reactor core power histories to-date and conservative estimates of future core designs, extended operation to 60 years will be bounded by 54 EFPY. (Reaching 54 EFPY would require a plant capacity factor in excess of 95 percent from now until the end of the period of extended operation.)

Time-Limited Aging Page 4.2-1 January 2010 Columbia Generating Station License Renewal Application Technical Information Fluence Projection Fluence values at 51.6 EFPY of reactor operation (analyzed by General Electric (GE) in Reference 4.8-3) are addressed in FSAR Section 4.3.2.8 and FSAR Table 4.3-1. These fluence analyses are based on the original licensed thermal power of 3323 megawatt-thermal (MWt) through fuel cycle 10, and the currently licensed thermal power uprated to 3486 MWt from cycle 11 through the end of operation. These fluence analyses are based on the methodology -of NEDC-32983P, "General Electric Methodology for Reactor Pressure Vessel Fast Neutron Flux Evaluation." NEDC-32983P was approved by NRC letter (Reference 4.8-4) with acceptability based :on the fact that the methodology followed the guidance in Regulatory Guide (RG) 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence." Subsequently, GE incorporated the fluence analyses into a personal computer worksheet to allow production of fluence estimates at other EFPY. For purposes of license renewal, the reported fluence was linearly extrapolated from 33.1 EFPY (the original 40-year end of life estimate) through 51.6 EFPY to 54 EFPY. Those projections match the fluence values obtained from the automated worksheet for 54 EFPY.A summary of the highest estimated values offluence for the RPV beltline shells and welds is shown in Table 4.2-1. Fluence is calculated at the inner surface (OT) of the vessel and at Y4 thickness (1/4T) depth into the vessel.Beitline Evaluation NUREG-1801 indicates that ferritic materials for RPV beltline shells, welds, and assembly components are to be evaluated for neutron irradiation embrittlement if high energy neutron fluence is greater than a threshold value of 1E+17 n/cm 2 (E >1 MeV) at the end of the license renewal term. The only RPV assembly items, other than the shells and welds in Table 4.2-1, that would experience neutron fluence greater than 1E+17 n/cm 2 during the period of extended operation are instrumentation nozzle N12 and residual heat removal/low-pressure coolant injection (RHR/LPCI) nozzle N6.Instrumentation nozzle N12 has a thickness less than 2.5 inches and therefore requires no fracture toughness evaluation per ASME Code Appendix G, Section G2223, and thus is not evaluated. Nozzle N6 is evaluated for ART in Section 4.2.3 and Table 4.2-5 below. As shown in Table 4.2-5, the ART for these nozzles is only 22.2 OF, versus 53.8 OF for the highest weld and 73.6 OF for the highest plate. Consequently, nozzle N6 is not the limiting material for the vessel. However, as nozzle N6 was evaluated for ART it meets thedefinition of a beltline component per 10 CFR 50, Appendix G.Time-Limited Aging Analyses Time-Limited Aging Analyses Page 4.2-2 January 2010 Page 4.2-2.January 2010 Columbia Generating Station License Renewal Application

If USE cannot be shown to remain above this limit, then an equivalent margin, analysis (EMA) must be performed to show that the margins of safety against fracture are equivalent to those required by Appendix G of Section Xl of the ASME Code.The USE calculation of record for the existing licensed period (33.1 EFPY) is Appendix F of GE NEDO-33144 (Reference 4.8-5). The initial (unirraditated) USE is not known for all the Columbia vessel plates and welds. For those plates and welds for which the initial USE is known, USE was projected using Regulatory Guide 1.99, Revision 2 methods. For the vessel plates and welds for which the initial USE is not known, USE EMAs were performed using the Boiling Water Reactor Owners Group EMA methodology. Results from the testing and analysis of surveillance materials were used in the EMA analyses.The values of USE projected to 54 EFPY are listed in Table 4.2-2. All of the projected USE values from Table 4.2-2 remain above 50 ft-lbs through the end of the period of extended operation (54 EFPY).The projected EMAs are listed in Table 4.2-3 and Table 4.2-4. The projected EMAs in Table 4.2-3, and Table 4.2-4 used the projected 54 EFPY fluence listed in Table 4.2-1, and the curves provided in RG 1.99 Figure 2. The predicted values were compared to the minimum 54 EFPY USE limits in BWRVIP-74-A. For the vessel beltline plates, the maximum decrease in USE was found to be 13.2 percent (see Table 4.2-3). This is less than the assumed decrease of 23.5 percent in the beltline plate equivalent margin analysis. Therefore, the maximum predicted decreases in USE for 54 EFPY for the beltline plates are bounded by the generic 54 EFPY equivalent margin analysis documented in BWRVIP-74-A. The projected USE for the vessel beltline plates is acceptable for the period of extended operation. For the welds associated with the vessel beltline plates, the maximum decrease in USE was found to be 21.6 percent (see Table 4.2-4). This is less than the assumed decrease of 39 percent in the equivalent margin analysis. Therefore, the maximum predicted decreases in USE for the welds in the vessel beltline region are bounded by the generic 54 EFPY equivalent margin analysis documented in BWRVIP-74-A.

This reference temperature changes as a function of exposure to neutron radiation resulting in an adjusted reference temperature, ART.The initial RTNDT is the reference temperature for the unirradiated material as defined in Paragraph NB-2331 of Section III of the ASME Boiler and Pressure Vessel Code. The change due to neutron radiation is referred to as ARTNDT.The ART is calculated by adding the initial RTNDT, the ARTNDT, and a margin to account for uncertainties as prescribed in Regulatory Guide 1.99, Revision 2.The ART evaluations of record for the vessel beltline plates and welds for the currently licensed period (33.1 EFPY), including power uprate conditions, are provided in NEDO-33144 (Reference 4.8-5). NEDO-33144 lists the initial RTNDT and chemistry values for the Columbia reactor vessel materials obtained from the Columbia vessel Certified Material Test Reports. Some chemistry factors were adjusted when Surveillance Capsule Data and Integrated Surveillance Program (ISP) best estimates were available, as described in NEDO-33144. The results and methodology in NEDO-33144, Revision 2 of Regulatory Guide 1.99 (Reference 4.8-6), and the projected fluence values listed in Table 4.2-1 were Used to project the ART for 54 EFPY. The results of this projection are summarized in Table 4.2-5 for vessel beltline plates and welds. The ART values projected to 54 EFPY are used to develop P-T limit curves, as discussed in Section 4.2.4.

The usage factors, as calculated in the design fatigue analyses, account for the design transients assumed for the original 40-year life of the plant. Therefore,the determination of cumulative usage factors used in the selection of postulated high energy line break locations are TLAAs The Fatigue Monitoring Program will identify when the transients for piping systems are approaching their analyzed numbers of cycles. Prior to any transient exceeding its analyzed number of cycles for a piping system, the design calculations for that system will be reviewed to determine if any additional locations should be designated as postulated high energy line breaks, under the original criteria of FSAR Section 3.6. If other locations are determined to require consideration as postulated break locations,. actions will be taken to address the new break locations. During initial plant startup, an induction heating stress improvement (IHSI) process was used on various RPV nozzles to safe end and safe end to pipe welds. In the 1994 refueling outage, Columbia performed a mechanical stress improvement process (MSIP) for multiple RPV nozzles to safe end and safe end'to pipe welds. No credit is taken for MSIP or IHSI in the calculation of CUFs for the Columbia vessel nozzles and safe ends.All Class 1 piping was reviewed for the power uprate. The power uprate evaluation scaled existing fatigue analyses based on the changes in stress expected from the power uprate. This evaluation showed that there was adequate margin in each system to accommodate the power uprate (the increased CUF after the power uprate was approximated by the report). The maximum CUFs for Class 1 piping are shown in Table 4.3-5. The Fatigue Monitoring Program uses the systematic counting of plant transient cycles to ensure that component design fatigue usage limits are not exceeded.Design fatigue usage for 40 years of operation is provided in Table 4.3-5 for the limiting reactor coolant pressure boundary components. A review of Columbia's documentation found several fatigue analyses for Class 1 valves that were TLAAs. The fatigue usage for those valves is based on transients that are tracked by the Fatigue Monitoring Program.

The design of ASME III Code Class 2 and 3 piping systems incorporates a cycle based stress range reduction factor fordetermining acceptability of piping design with respect to thermal stress range.Columbia SSCs designated as quality group D are designed to ANSI B31.1, which also incorporates stress range reduction factors based Upon the number of thermal cycles.In general, a stress range reduction factor of 1.0 in the stress analyses applies for up to 7,000 thermal cycles. The allowable stress range is reduced by the stress range reduction factor if the number of thermal cycles exceeds 7,000. If fewer than 7,000 cycles are expected through the period of extended operation, then the fatigue analysis (stress range reduction factor) of record will remain valid through the period of extended operation. The non-Class 1 aging management reviews for Columbia determined piping locations susceptible to fatigue. The fatigue evaluation of non-Class 1 components determined whether the associated operating temperature exceeded threshold values for the affected materials and, if so, evaluated the number of transient cycles expected. In every case, the number of projected cycles for 60 years was found to be less than 7,000for -piping and in-line components whose temperatures exceed threshold values.Therefore, fatigue for non-Class 1 piping and in-line components remains valid for the period of extended operation. None of the non-Class 1 vessels, heat exchangers, storage tanks, or pumps were designed to ASME Section VIII, Division 2 or ASME Section III, Subsection NC-3200.Therefore, there is no fatigue TLAA for these components.

Non-class 1 components that are Quality Group B or C are designed and constructed to the ASME Boiler and Pressure Vessel Code. The design of ASME III Code Class 2 and 3 piping systems incorporates a cycle based stress range reduction factor for determining acceptability of piping design with respect to thermal stress range. Columbia SSCs designated as quality group D are designed to ANSI B31.1, which also incorporates stress range reduction factors based upon the number of thermal cycles. In general, a stress range reduction factor of 1.0 in the stress analyses applies for upto 7,000 thermal cycles. The allowable stress range is reduced by the stress range reduction factor if the number of thermal cycles exceeds 7,000. If fewer than 7,000 cycles are expected through the period of extended operation, then the fatigue analysis (stress range reduction factor) of record will remain valid through the period of extended operation.

The non-Cla,ss 1 aging management reviews for Columbia determined piping locations susceptible to fatigue. The fatigue evaluation of non-Class 1 components determined whether the associated operating temperature exceeded threshold values for the affected materials and, if so, evaluated the number of transient cycles expected. In

• every case, the number of proJected cycles for 60 years was found to be less than 7,000 for -piping and in-line components whose temperatures exceed threshold values. Therefore, fatigue for non-Class 1 piping and in-line components remains valid for the period of extended operation.

None of the non-Class 1 vessels, heat exchangers, storage tanks, or pumps were designed to ASME Section VIII, Division 2 or ASME Section III, Subsection NC-3200. Therefore, there is n,o fatigue TLAA for these components. Disposition: 10 CFR 54.21(c)(1)(i) -The analyses remain valid for the period of extended operation.

These attributes are discussed below.Analytical Methods The Columbia EQ Program uses the same analytical models in the re-analysis of'an aging evaluation as those applied during the previous qualification analysis. The Arrhenius methodology is an acceptable thermal model for performing a thermal aging evaluation. The analytical method used for a radiation aging evaluation is to demonstrate qualification for the total integrated dose (that is, normal radiation dose for the projected installed life plus accident radiation dose). For license renewal, one acceptable method of establishing the 60-year normal radiation dose is to multiply the 40-year normal radiation dose by 1.5 (that is, 60 years divided by 40 years). The result is added to the accident radiation dose to obtain the total integrated dose for the component. For cyclical aging, an approach similar to that used for radiation dose may be used. Other models may be justified on a case-by-case basis.Data Collection and Reduction Methods Reducing excess conservatism in the component service conditions (for example, temperature, radiation, cycles) used in the previous aging evaluation is a method used for a re-analysis in the Columbia EQ Program. Temperature data used in an aging evaluation should be conservative and based on plant design temperatures or on actual plant temperature data. When used, plant temperature data can be obtained in several ways, including monitors used for technical specification compliance, other installed monitors, measurements made by plant operators during rounds, and temperature sensors installed on large motors (while the motor is not running). A representative number of temperature measurements are evaluated to establish the temperatures used in an aging evaluation.- Plant temperature data may be used in an agingevaluation in different ways, such as: a) directly applying the'plant temperature data inthe evaluation, or b) using the plant temperature data to demonstrate conservatism when using plant design temperatures for an evaluation. Any changes to material activation energy values as part of a re-analysis must be justified. Similar methods of reducing excess conservatism in the component service conditions used in previous aging evaluations can be used for radiation and cyclical aging.Underlying Assumptions The Columbia EQ Program environmental qualification evaluations contain sufficient conservatism to account for most environmental changes occurring due to plant conditions and events. When unexpected adverse conditions are identified during operational or maintenance activities that affect the environment of a qualified component, the affected EQ component is evaluated, and appropriate corrective actions are taken, which may include changes to the qualification bases and conclusions.Time-Limited Aging Analyses Page 4.4-2 January 2010 Columbia Generating Station License Renewal Application

• Columbia Generating Station License Renewal Application Technical Information Acceptance Criteria and Corrective Actions Under the Columbia EQ Program, the re-analysis of an aging evaluation could extend the qualification of a component.

If the qualification cannot be extended by re-analysis,the component must be refurbished, replaced, or re-qualified prior to exceeding-the current qualified life. A re-analysis should be performed in a timely manner (such that sufficient time is available to refurbish, replace, or re-qualify the component if the re-analysis is unsuccessful). Therefore, the EQ TLAAs are dispositioned per 10 CFR 54.21(c)(1)(iii). The Columbia EQ Program is part of the current licensing basis, is in compliance with 10 CFR 50.49, and is the basis for managing the aging of EQ equipment in the current license term.In Section X.E1 of NUREG-1801, the NRC has already generically evaluated EQ programs put in place to meet 10 CFR 50.49 and found them acceptable for managing the aging of electrical EQ equipment during the period of extended operation. NUREG-1800, Section 4.4.2.1.3, states that if a licensee takes credit for this generic evaluation of the EQ Program, "...the applicant should indicate that the material referenced is applicable to the specific plant involved and should provide the information necessary to adopt the finding of program acceptability as described and evaluated in this report." To this end, a comparison of the EQ Program to the evaluation in NUREG-1801, Section X.E1 was performed with the results documented in Appendix B of this Application. From this review, it was concluded that the Columbia EQ Program contains the same program elements evaluated in NUREG-1801 and that the EQ Program is consistent with the generic evaluation performed by the NRC and documented in NUREG-1801. Continued effective implementation of the Columbia EQ Program assures that the aging effects will be adequately managed and that EQ components will continue to perform their intended functions for the period of extended operation.

The Columbia EO Program is part of the current licensing basis, is in compliance with 10 CFR 50.49, and isthe basis for managing the aging of EO equipment in the current license term. In Section X.E1 of NUREG-1801, the NRC has already genericaliy evaluated EO programs put in place to meet 10 CFR 50.49 and found them acceptable

• for managing the aging of electrical EO equipment during the' period of extended operation.

NUREG-1800, Section 4.4.2.1.3, states that if a licensee takes credit for this generic evaluation of the EO Program, ": .. the applicant should indicate that the material referenced is applicable! to the specific plant involved and should provide the information necessary to adopt the finding of program acceptability as described and evaluated in this report." To this end, a comparison of the EO Program to the evaluation in NUREG-1801, Section X.E1 was performed with the results documented in Appendix B of this Application. From this review, it was concluded that the Columbia EO Program contains the same program elements evaluated in NUREG-1801 and that the EO Program is consistent with the generic evaluation performed by .the NRC and documented in NUREG-1801. Continued effective implementation of the Columbia ,EO Program assures that the aging effects will be adequately managed and that EO components will continue to perform their intended functions for the period of extended operation.

There are 84 24-inch diameter downcomers and 18 28-inch downcomers. Three of the downcomers are capped (see FSAR Section 6.2.1.1.3.2). The downcomer vent pipes are designed to contain and direct uncondensed drywell steam into the suppression pool following a pipe break accident. The upper portion of the downcomers are designed and constructed in accordance with ASME Section III Class 2 requirements while the lower portion are designed and constructed to ASME Section III Class 3 requirements. The only effect of this code break is to eliminate radiography requirements for the circumferential weld joining the upper and lower portions of the downcomers (see FSAR Section 3.8.3.4.9). A fatigue evaluation of the downcomers was performed even though it is not an ASMECode requirement. The fatigue evaluation of the downcomer lines in the wetwell air volume was based on the number of cycles as presented in FSAR Table 3A.4.1-3 (reproduced in Section 4.6 above).

The indications were 'present in past inservice inspection examinations, but became rejectable under current ASME Section XI, IWB-3610 requirements. The rejected indications were evaluated and determined to be acceptable for continued service without repair, as reported to the NRC in Energy Northwest letter G02-05-153 (Reference 4.8-14)._ The indications were evaluated per the guidelines of ASME Section XI, IWB-3610, which include acceptance criteria based on the applied stress intensity factors, using conservative assumptions in the applied stresses to determine the stress intensity factors for comparison to Code allowables. This evaluation calculated a fatigue crack growth (0.0064 inches) at the end of 33.1 EFPY vessel service life) that is insignificant in comparison to the bounding initial crack size-of 0.39 inch. It also determined that the applied stress intensity factor (about 30 ksi*in) is well below the allowable Kic of 63.25 ksilin.The calculation used two time-limited assumptions based on the 1 40-year life of the plant, and thus is a TLAA.1. The /4 T neutron fluence at weld BG (5.11E+17 n/cm 2 at 33.1 EFPY) was used for both welds. This fluence was used to calculate the material properties of the cracked area, and hence the crack propagation. As can be seen from Table 4.2-1, the projected .1/4 T fluence for Weld BG at 54 EFPY is 8.1 0E+1 7 n/cm 2.2. 500 significant thermal transients were assumed (SRV blowdown cycles being the worst case thermal cycle). From Table 4.3-2, it can be seen that no SRV blowdown cycles are expected through 60 years of operation; furthermore, only 409 significant thermal transients are expected (233 heatup/cooldowns, 166-scrams, and 10 HPCS actuations). Although this calculation easily meets the. acceptance criteria, it is based on a time-limited assumption of neutron fluence that will not remain valid for the period of extended operation. This indication is currently scheduled for re-inspection in 2015.Columbia will re-evaluate the indication based on the results of the 2015 inspection and either project this analysis through the period of extended operation or continue augmented inspections as required by the ASME code.

The restrictor assembly has no moving parts and consists of a venturi-type nozzle insert welded-into the main steam line.FSAR Section 5.4.4.4 indicates that only very slow erosion of the main steam flow restrictor is expected. Erosion of a flow restrictor is a safety concern since it could impair the ability of the flow restrictor to limit vessel blowdown following a main steam line break. Since erosion is a time-related phenomenon, the analysis for the effect it has on the flow restrictors over the life of the plant is a TLAA. Cast stainless steel (SA351, Type CF8) was selected for the steam flow restrictor material because it has excellent resistance to erosion-corrosion from high velocity steam.Columbia has projected the erosion of the main steam flow restrictors for the period of extended operation. The projection concludes that after 60 years of erosion on the main steam flow restrictors, the choked flow will still be less than 200 percent of normal flow. Therefore, the main steam flow restrictors will continue to perform their intended function for the period of extended operation. Disposition: 10 CFR 54.21(c)(1)(ii) - The TLAA for erosion of the main steam line flow restrictors has been projected to the end of the period ofextended operation.

• Columbia Generating Station License Renewal Application Technical Information A.0 FINAL SAFETY ANALYSIS REPORT SUPPLEMENT A.1 INTRODUCTION This appendix provides the information to be submitted in a Final Safety Analysis Report (FSAR) Supplement as required by 10 CFR 54.21(d) for the License Renewal Application (LRA). The LRA contains the technical information required by 10 CFR 54.21(a) and (c). Section 3 of the LRA contains the results of the aging management reviews. The programs and activities credited to manage the effects of aging. are described in LRA Appendix B. Section 4 of the LRA documents the evaluations of time-limited aging analyses for the period of extended operation.

LRA Section 3, Section 4, and Appendix B have been used to prepare the program and activity descriptions that are contained in this appendix. In addition, this appendix contains a listing of commitments associated with license renewal. The information presented in LRA Sections A.1.2, A.1.3, and A.1.4 will be incorporated into the FSAR following issuance of the renewed operating license. 'The listing of commitments for license renewal in LRA Section A.1.5 is provided for information, but will not be included in the FSAR. The license renewal commitments will be'tracked within the Columbia regulatory commitment management program (see Commitment Item Number 57).A.1.1 New FSAR Section The information contained in LRA Sections A.1.2, A.1.3, and A.1.4 will be incorporated into the FSAR to document aging management programs and activities credited in the Columbia integrated plant assessment and time-limited aging analyses evaluated for the period of extended operation. A.1.2 Aging Management Program and Activities The license renewal integrated plant assessment identified existing and new aging management programs necessary to provide reasonable assurance that components within the scope of license renewal will continue to perform their intended functions consistent with the current licensing basis (CLB) for the period .of extended operation. This section describes the aging management programs and activities identified during the integrated plant assessment. The aging management programs will be implemented prior to the period of extended operation. One-time inspections will be conducted within the 10-year period prior to beginning the period of extended operation. The aging management programs identified as necessary in association with the evaluation of time-limited aging analyses are described in Section A. 1.3.Three elements of an effective aging management program that are common to each of the aging management programs are corrective actions, confirmation process, andadministrative controls. These elements are included in the Operational Quality Final Safety Analysis Report Supplement Page A-7 January 2010* Columbia Generating Station License Renewal Application Technical Information A.O FINAL SAFETY ANALYSIS REPORT SUPPLEMENT A.1 INTRODUCTION This appendix provides the information to be submitted in a Final Safety Analysis Report (FSAR) Supplement as required by 10 CFR 54.2t(d) for the License Renewal' Application (LRA).

• A.1.1 New FSAR Sect:ion
• The information contained in lRA Sections A.1.2, A.1.3, and A.1.4 will be incorporated into the FSAR to document aging management programs and activities credited in the . Columbia integrated plant assessment and time-limited aging analyses evaluated for the period of extended operation.

' A.1.2 Aging Management Program and Activities The license renewal integrated plant assessment identified existing and new aging management programs necessary to provide reasonable assurance that components within the scope of license renewal will continue to perform their intended functions consistent with the current licensing basis (CLB) for the period *ofextended operation. This section describes the aging management programs and activities identified during the integrated plant assessment. The aging management programs will be implemented prior to the period of extended operation. One-time inspections will be conducted within the 10-year period prior to beginning the period of extended operation. The aging managememt programs identified as necessary' in association with the evaluation bf time-limitBd aging analyses are described in SectionA.1.3. Three elements of an effective aging management program that are common to each of the aging management programs are corrective actions, confirmation proGess, and administrative controls. 'These elements are included in the Operational Quality Final Safety Analysis Repol1 Supplement Page A-7 January 2010 ( Columbia Generating Station License Renewal Application Technical Information Assurance Program Description (OQAPD) for Columbia, which implements the requirements of 10 CFR 50, Appendix B.Prior to the period of extended operation, the elements of corrective actions, confirmation process, and administrative controls in the OQAPD will be applied to required aging management programs for both safety-related and non-safety related structures and components determined to require aging management during the period of extended operation. A.1.2.1 Aboveground Steel Tanks Inspection The Aboveground Steel Tanks Inspection detects and characterizes the conditions on the bottom surfaces of the condensate storage tanks. The inspection provides direct evidence through volumetric examination as to whether, and to what extent, a loss of material due to corrosion has occurred in inaccessible areas (i.e., tank base and bottom surface).The Aboveground Steel Tanks 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.1.2.2 Air Quality Sampling Program The Air Quality Sampling Program is an existing prevention and condition monitoring program that manages loss of material due to corrosion for Diesel Starting Air (DSA)components that contain compressed air through periodic sampling of the air for hydrocarbons, dewpoint, and particulates and periodic ultrasonic inspection of the DSA System air receivers.

• Columbia Generating StationLicense Renewal Application Technical Information A.1.3.1 Reactor Vessel Neutron Embrittlement Neutron embrittlement is the change in mechanical properties of reactor vessel materials resulting from exposure to fast neutron flux (E>1.0. MeV) in the beltline region of the reactor core. The most pronounced material change is a reduction in fracture toughness.

As fracture toughness decreases with cumulative fast neutron exposure,the material's resistance to crack propagation decreases. Fracture toughness is also dependent on temperature. The reference temperature for nil-ductility transition (RTNDT)is the temperature above which the material behaves in a ductile manner and below which the material behaves in a brittle manner. As fluence increases, RTNDT increases, and higher temperatures are required for the material to continue to act in a ductile manner.Requirements associated with fracture toughness, pressure-temperature limits, and material surveillance programs for the reactor coolant pressure boundary are contained in Appendices G and H of 10 CFR 50.The analyses associated with evaluation of the effect of neutron embrittlement on the reactor pressure vessel for 40 years are TLAAs.

• Columbia Generating Station License Renewal Application Technical Information A.1.3.7.3 Main Steam Flow Restrictor Erosion Analyses The main steam line flow restrictors are designed to limit coolant flow rate from the reactor vessel (before the MSIVs are closed) to less than 200 percent of normal flow in the event of a main steam line break outside the containment.

Erosion of a flow restrictor is a safety concern since it could impair the ability of the flow restrictor to limit vessel blowdown following a main steam line break. Since erosion is a time-related phenomenon, the analysis for the effect it has on the flow restrictors over the life of the plant is a TLAA. Cast stainless steel (SA351, Type CF8) was selected for the steam flow restrictor material because it has excellent resistance to erosion-corrosion from high velocity steam.The erosion of the main steam flow restrictors has been projected for the period of extended operation. The projection concludes that after 60 years of erosion on the main steam flow restrictors, the choked flow will still be less than 200 percent of normal flow. Therefore, the main steam flow restrictors will continue to perform their intended function and the existing accident radiological release analysis will remain valid for the period of extended operation.

For those programs that are either new or plant-specific, the above format is followed along with the additional provision of a discussion of each of the 1 0 elements associated with the program. Aging Management Programs Page 8-7 January 2010 Columbia Generating Station License Renewal Application Technical Information B.1.3 Quality Assurance Program and Administrative Controls Three elements of an effective aging management program that are common to each of the aging management programs are corrective actions, confirmation process, and administrative controls. These elements are included in the Operational Quality.Assurance Program Description (OQAPD) for Columbia, which implements the requirements of 10 CFR 50 Appendix B. The OQAPD is described in FSAR ,Sections 3.1.2.1.1, 13.4, and 17.2.Prior to the period of extended operation, the elements of corrective actions, confirmation process, and administrative controls in the OQAPD will be applied to required aging management programs for both safety-related and NSR structures and components determined to require aging management during the period of extended operation. The corrective actions, confirmation process, and administrative controls in the OQAPD, to be applied to the credited aging management programs and activities for the structures and components determined to require aging management, are consistent with the related discussions in the Appendix on Quality Assurance for Aging Management Programs in NUREG-1801, Volume 2.The elements of corrective actions, confirmation process, and administrative controls of the OQAPD are described in the sections below, including a general comparison to theassociated elements of the corresponding NUREG-1801 aging management programs (AMPs), which indicate that the "staff finds the requirements of 10CFR Part 50, Appendix B acceptable to address the corrective actions (and confirmation process)." Corrective Actions: Corrective actions are implemented through the site corrective action program, which includes the initiation, processing, and evaluation of condition reports, that satisfies the requirements of 10 CFR 50, Appendix B, Criterion XVI. Conditions adverse to quality, an all inclusive term used in reference to failures, malfunctions, deficiencies, defective items, and non-conformances are identified, reported to management, and corrected. In. the case of significant conditions adverse to quality, measures are implemented to ensure that the root cause is determined and that corrective actions are taken to preclude recurrence.The corrective action program is the subjectlof periodic NRC examination and Columbia self-assessment and audit. In general, problems are effectively identified, evaluated and prioritized, and effective corrective actions implemented for conditions adverse to quality. Some program shortfalls have been identified, but corresponding process improvement plans have been developed and implemented. The current program is, therefore, adequate for aging management considerations.

• Columbia Generating Station* License Renewal Application Technical Information Confirmation Process: The focus of the confirmation process is on the follow-up actions taken to verify effective implementation

'of corrective actions and preclude repetition of significant conditions adverse to quality. The corrective action- program includes the requirement that measures be taken to preclude repetition of significant conditions adverse to quality.These measures include actions to verify effective implementation of proposed corrective actions. The confirmation process is part of the corrective action program and, for significant conditions adverse to quality, includes:* reviews to assure proposed actions are adequate,* tracking and reporting of open corrective actions," Root Cause and Apparent-Common Cause evaluations, and" reviews of corrective action effectiveness. Effectiveness reviews are conducted as part of the corrective action process to ensure that all corrective actions have been completed and to identify any repetition of the event. The corrective action process is also monitored for potentially adverse trends.The existence of an adverse trend due to recurring or repetitive adverse conditions will result in the initiation of a follow-up condition report.Administrative Controls: Administrative controls that govern aging management activities are established within the document control procedures that implement: (1) industry standards related to administrative controls and quality assurance for the operational phase of nuclear power plants, and (2) the requirements of 10 CFR 50, Appendix B, Criterion VI.Plant policies, directives, and procedures are written and controlled to specify and manage various activities, particularly those related to compliance with 10CFR 50, Appendix B. The phrase "administrative control" refers to the adherence to the policies, directives, and procedures, and includes the formal review and approval process that the plant policies, directives, and procedures undergo as they are issued (and subsequently revised). The individual documents (i.e., the plant policies, directives, and procedures), in conjunction with the plant's quality assurance program documents, provide the overall administrative framework to ensure regulatory requirements are met.B.1.4 Operating Experience Operating experience for existing Columbia plant programs and activities was reviewed as an input to the aging management program evaluations. The operating experience review demonstrates the effectiveness of the plant programs and activities that are credited with aging management for the period of extended operation. Aging Management Programs Page B-9 January 2010* .' Confirmation Process: Generating Station License Renewal Application Technical Information The focus of the confirmation process is on the follow-up actions taken to verify effective* implementation 'of corrective actions and preclude repetition of significant conditions adverse to quality. The corrective action-program includes the requirement that measures be taken to preclude repetition of significant conditions adverse to quality. These measures include actions to verify effective implementation of proposed corrective actions. The confirmation process is part of the corrective action program and, for significant conditions adverse to quality, includes:

• reviews to assure proposed actions are adequate,
• tracking and reporting of open corrective actions, .
• Root Cause and Apparent-Common Cause evaluations, and

Effectiveness reviews are conducted as part of the corrective action process to ensure that all corrective actions have been completed and to identify any repetition of the event. The corrective action process is also monitored for potentially adverse trends. The existence of an adverse trend due to recurring or repetitive adverse conditions will result in the initiation of a follow-up condition report. Administrative Controls: Administrative controls that govern aging management activities are established within the document control procedures that implement: (1) industry. standards related to administrative controls and quality assurance for the operational phase of nuclear power plants, and (2) the requirements of 10 CFR 50, Appendix B, Criterion VI. Plant policies, directives, and procedures are written and controlled to specify and. manage various activities, particularly those related to compliance with 10'CFR 50, Appendix B. The phrase "adll)inistrative control" refers to the adherence to the policies, directives, and procedures, and includes the formal review and approval process that the plant policies, directives, and procedures undergo as they are issued (and subsequently revised). The individual documents (i.e., the plant policies, directives, and procedures), in conjunction with the plant's quality assurance program documents, provide the overall administrative framework to ensure regulatory requirements are met. B.1.4 Operating Experie,:",ce Operating experience for existing Columbia plant programs and activities was reviewed as an input to the aging management program evaluations. The operating experience review demonstrates the effectiveness of the plant programs and activities that are credited with aging management for the period of extended operation. Aging Management Programs Page 8-9 January 2010 Columbia Generating Station License Renewal Application Technical Information Plant procedures require that the discovery of conditions adverse to quality be documented in accordance with the corrective action program. A review of plant records for the most recent seven-year period (January 2001 through July 2008) was performed in order to identify age-related issues of degradation related to current plantoperation. The scope of the review included reports generated under the corrective action program and licensee event reports. These records provide documentation ofsituations where systems, structures, and components exhibit conditions adverse to quality, including age-related degradation. Keywords related to aging and degradation were used to search the records. The operating experience review provides the basis for the determination that existing programs are either effective or require enhancement; that one-time inspections are appropriate to verify that either aging is not occurring or that aging is being effectively managed by an existing program; or that a new program is required to be established to manage the effects of aging.The operating experience review included consideration of the results of programmatic assessments performed by Columbia and of those performed by outside agencies, including the NRC. Past corrective actions resulting in program enhancements are included in the evaluation of program effectiveness. Industry operating experience was considered specifically for new programs with no plant-specific operating experience or when industry events were significant for existing programs. The operating experience review provides objective evidence that the effects of aging will be managed for the period of extended operation. B.1.5 Aging Management Programs Table B-1 provides a listing of the NUREG-1801 aging management programs and the corresponding aging management programs for Columbia. Table B-2 provides a summary of the aging management programs for Columbia with respect to consistency with NUREG-1801 aging management programs.

• Columbia Generating Station License Renewal Application Technical Information-., Periodic inspection of the external surfaces of the tanks (including protective coatings), other than the tank bottoms, is included in the scope of the External Surfaces Monitoring Program.* Preventive Actions The external surfaces of the condensate storage tanks have protective coatings that are consistent with industry practice.

However, there is no sealant or caulking at the interface edge between the tanks and concrete foundation. No other actions are taken as part of the Aboveground Steel Tanks Inspection or the External Surfaces Monitoring Program to prevent aging effects or to mitigate aging degradation.

• Parameters Monitored or Inspected The Aboveground Steel Tanks Inspection will determine wall thickness as a measure of loss of material for the tank bottom.The related parameters inspected by the External Surfaces Monitoring Program include visual evidence of a loss of material or other degradation.
• Detection of Aging Effects The Aboveground Steel Tanks Inspection will use established volumetric examination techniques performed by qualified personnel to inspect locations on the bottom surface of a condensate storage tank to determine whether, and to what extent, a loss of material has occurred or is likely to occur during the period of extended operation.

The Aboveground Steel Tanks Inspection will be conducted after the issuance of therenewed license and prior to the end of the current operating license for Columbia, with sufficient time to implement programmatic oversight for the period of extended operation. The activities will be conducted no earlier than 10 years prior to the end of the current operating license, so that conditions are more representative of the conditions expected during the period of extended operation. The results of this inspection will supplement the existing inspection of accessible external surfaces conducted by the External Surfaces Monitoring Program.Monitoring and Trending No actions are taken as part of the Aboveground Steel Tanks Inspection to monitor or trend inspection results.

• Columbia Generating Station License Renewal Application Technical Information Type B and C leakage rate test results from the 2007 Refueling Outage (R18) are summarized in the.local leak rate test post outage report. The R18 local leak rate test involved ninety-one Type B and C air tests. Twenty-five Type B tests were conducted,.including the personnel airlock barrel test. All Type B as found leak rates were below their administrative limits with the exception of the containment-side flange (CEP-V-2A), which had a leak rate exceeding its administrative limit. This flange was checked using a soap solution with test pressure applied and showed no external leakage. This visual inspection confirmed that the leakage recorded was into the system rather than a breach of the containment penetration.

Sixty-six Type C tests were.conducted. All but eight valves had as found leak rates below their administrative limits. The valves with leak rates in excess of their administrative limit required corrective actions to reduce their leak rates.

• Detection of Aging Effects -Require that an inspection of a representative sample of buried piping be performed within the 10-year period prior to entering the period of extended operation (i.e., between year 30 and year 40).Require an additional inspection of a representative sample of buried piping be performed within 10 years after entering the period of extended operation (i.e., between year 40 and year 50).Operating Experience No history of piping degradation due to external corrosion of buried piping was identified for Columbia through searches of operating experience or discussions with program owners. Columbia operating experience demonstrates that the coating of buried steel piping and tanks is effective in managing the effects of aging. Plant design considerations addressed the potential for degradation of buried piping components through the application of protective coatings.A review was conducted of station piping failures, and it was determined that there had been no documented failures attributed to externally-initiated corrosion.

Identified instances of leakage associated with buried piping have been the result of internal corrosion. The environmental conditions at Columbia are very good based on the sandy soil and electrolyte resistivity of the soil which is considered very high. This has resulted in minimal degradation of buried piping as evidenced by excavations of certain sections ofpiping for examination. There have been no significant areas of degradation caused by protective coating failure. This was determined after a section of buried Standby Service Water (SW) System piping was excavated and evaluated in 2007.Conclusion The Buried Piping and Tanks Inspection Program will manage loss of material due to corrosion for susceptible piping components and tanks in buried environments. The Buried Piping and Tanks Inspection Program, with the required enhancements, provides reasonable assurance that the aging effects will be managed such that components subject to aging management review will continue to perform their intended functions consistent with the current licensing basis for the period of extended operation.

• Columbia Generating Station License Renewal Application Technical Information During Refueling Outage (RFO) 16 at Duane Arnold Energy Center, inspections of welds susceptible to intergranular stress corrosion cracking (IGSCC) identified flaw indications on three recirculation riser nozzle-to-safe-end welds (RRB-F002 , RRD-F002 and RRF-F002). The original scope of the examinations included three recirculation riser welds and one core spray nozzle-to-safe-end weld. The inspection scope was therefore expanded to include all of the remaining F002 welds, as well as the other similarly designed core spray welds. One weld was ground flush and re-inspected, and has been dispositioned.

Two welds were repaired using weld overlays.Columbia operating experience: One indication was identified in stainless steel recirculation system piping to valve weld 20RRC(6)-8 during Refuel Outage 6 (1991). The sample size was expanded in accordance with GL 88-01. The indication did not show IGSCC characteristics; however, it was evaluated as IGSCC. The indication was determined to be acceptable for continued operation without repair. In 1996, after four successive inspections without significant change in the indication, the indication was reclassified to an IGSCC Category E weld in accordance with GL 88-01. The NRC staff was kept informed of the indication status and concurred with the actions taken and the reclassification of the indication. The weld was examined in 2001 using technology approved as part of the EPRI Performance Demonstration Initiative and no indications associated with IGSCC were identified. It was determined that the indication was not due to IGSCC and the weld was reclassified as Category B. All previous examinations were re-evaluated using the 2001 methods, and it wasconcluded that the indication had shown no identifiable growth in either length or depth in the 10 years that it had been monitored. A second indication, identified in RRC nozzle to safe end weld 24RRC(2)A-1 in 1998, has been verified to be an original construction weld repair. There is no indication of IGSCC in this weld.Therefore, continued implementation of the program provides reasonable assurance that stress corrosion cracking of austenitic stainless steel will be managed so that components crediting the BWR Stress Corrosion Cracking Program will continue to perform their intended function consistent with the current licensing basis during the period of extended operation.The site corrective action program and an ongoing review of industry operating experience will be used to ensure that the program continues, to be effective in managing the identified aging effects.Aging Management Programs Page B-49 January 2010 Aging Management Programs Page B-49 January 2010* *

• Columbia Generating Station License Renewal Application Technical Information B.2.11 BWR Water Chemistry ProgramProgram Description The BWR Water Chemistry Program will mitigate damage related to loss of material due to corrosion or erosion, cracking due to SCC, and reduction of heat transfer due to fouling of plant components that are within the scope of license renewal and contain or are exposed to treated water, treated water in the steam phase, reactor coolant, or treated water in a sodium pentaborate solution. The program manages the relevantconditions (e.g., concentrations of chlorides, oxygen, and sulfates) that could lead to the onset and propagation of a loss of material, cracking, or reduction of heat transfer through proper monitoring and control consistent with the current EPRI water chemistry guidelines. The relevant conditions are specific parameters such as sulfates, halogens, dissolved oxygen, and conductivity that could lead to, or are indicative of, conditions for corrosion or SCC of susceptible materials, as well as erosion and fouling. The BWR Water Chemistry Program is a mitigation program.The BWR Water Chemistry Program is supplemented by separate one-time inspections of representative areas of treated water systems.

Based on review of plant-specific and industry operating experience, the identified aging effects will require inspection to determine the presence (and extent) of any degradation associated with the non-environmentally qualified cable electrical connections. Plant operating experience has shown that the corrective action program hasaddressed issues related to degraded cable connections in recent years. Cable connections have been identified with degraded electrical continuity (i.e., 'increased resistance), primarily as a result of loosened electrical connections or corrosion. For example, corroded electrical connections were identified in the cooling tower lighting panels (which are not within the scope of license renewal), and an abnormally warm connection on a diesel generator power panel was identified via thermography.

( Aging Management Programs Page 8-103 January 2010 / Columbia Generating Station License Renewal Application Technical Information B.2.24 Fatigue Monitoring Program Program Description The Fatigue Monitoring Program manages fatigue of the reactor pressure vessel by tracking thermal cycles as required by Technical Specification 5.5.5, "Component Cyclic or Transient Limit." The Fatigue Monitoring Program also manages fatigue of other components (including the ASME Class 1 reactor coolant pressure boundary, high energy line break locations, and Primary Containment) by tracking transient cycles. The Fatigue Monitoring Program is a combination of time-limited aging analyses (cumulative usage factor calculations) and transient counting procedures. The Fatigue Monitoring Program uses the systematic counting of plant transient cycles to ensure that the numbers of analyzed cycles are not exceeded, thereby ensuring that component fatigue usage limits are not exceeded.The BWR Vessel Internals Program contributes to managing fatigue of the jet pumps by checking the jet pump set screw gaps each outage. If any out of specification-gaps are found, Columbia will calculate the additional fatigue accumulated by the jet pumps due to those gaps.The Fatigue Monitoring Program acceptance criteria are to maintain the number of counted transient cycles below the analyzed number of cycles for each transient. The Columbia program periodically updates the cycle counts. When the accumulated cycles approach the analyzed design cycles, corrective action is required to ensure the analyzed number of cycles is not exceeded. Corrective action may include update of the fatigue usage calculation. Any re-analysis will use an NRC-approved version of the ASME code or NRC-approved alternative (e.g., NRC-approved code case) to determine a valid CUF.Columbia has assessed the impact of the reactor coolant environment on the sample of critical components identified in NUREG/CR-6260. These components were evaluated by applying environmental life correction factors to ASME Code fatigue analyses.Formulae for calculating the environmental life correction factors are contained in NUREG/CR-6583 for carbon and low alloy steels and in NUREG/CR-5704 for austenitic stainless steel. The austenitic stainless steel formulae are also applied to nickel alloys.Columbia will enhance the Fatigue Monitoring Program to include the cycles analyzed for the effects of the reactor coolant environment on fatigue prior to the period of extended operation.

Columbia operating experience: The three most recent counting of cycles show the systematic implementation of the Fatigue Monitoring Program.In August 2000, Columbia operated for a period of time with the recirculation pumps in an unbalanced mode (pump speeds different by more than 50%). The effect of that flow on the fatigue usage of the jet pumps was evaluated. Jet pump clamps were installed on all 20 jet pumps during refueling outage R-17 (2005). Each jet pump mixer was clamped to its diffuser to minimize flow induced vibration caused by leakage at the mixer to diffuser, slip joint interface. As long as the set screw gaps remain within their revised criteria no additional fatigue due to bypass leakage flow induced vibration is accumulated.

The program manages the relevant conditions that could lead to the onset and propagation of a 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. The relevant conditions are specific contaminants such as water or microbiological organisms in the fuel oil that could lead to corrosion of susceptible materials.

Exposure to these contaminants is minimized by verifying the quality of new fuel oil before it enters the storage tanks and by periodic sampling to ensure the tanks are free of water and particulates. The Fuel Oil Chemistry Program is a mitigation program.The Fuel Oil Chemistry Program is supplemented by the Chemistry Program Effectiveness Inspection, which is a separate one-time inspection of representative areas of the diesel fuel oil system, such as low points where contaminants could accumulate. The one-time inspection provides further confirmation that loss of material, as well as cracking of susceptible copper alloys, is effectively mitigated or to detect and characterize whether, and to what extent, degradation is occurring.

Control cables, instrument cables, and low-voltage power cables have been identified with degraded insulation, primarily as a result of exposure to excessive localized overheating. There have been no failures of cables directly attributed to water treeing. Columbia has not experienced any degradation failures of medium-voltage cables. However, two 480-V power cables have failed due to damage incurred during installation and subsequent moisture intrusion. One medium-voltage cable failed because it exceeded its ampacity rating.Recent inspections of medium-voltage manholes identified two manholes adjacent to the cooling towers with standing water. The source of water has not been determined. This is a current licensing basis issue, and the corrective action program will be used to determine the source, to correct or mitigate the problem, and to determine the future inspection frequency needed based on the cause and the corrective actions taken. A search of plant operating experience identified no other cases of medium-voltage manholes having water intrusion. Industry operating experience will be considered in the development of this program.Required Enhancements Not applicable, this is a new program.Conclusion The Inaccessible Medium-Voltage Cables Not Subject to 10 CFR 50.49 EQ Requirements Program will manage degradation of conductor insulation for inaccessible, non-environmentally qualified medium-voltage cables. The Inaccessible Medium-Voltage Cables Not Subject to 10 CFR 50.49 EQ Requirements Program will provide reasonable assurance that the aging effects will be managed such that the inaccessible, non-environmentally qualified medium-voltage cables subject to aging management review will continue to perform their intended functions consistent with the current licensing basis for the period of extended operation.

Aging Management Programs Page 8-135 January 2010 Columbia Generating Station License Renewal Application Technical Information B.2.33 Inservice Inspection (ISI) Program Program Description The Inservice Inspection (ISI) Program manages cracking due to SCC/IGA and flaw growth of reactor coolant system pressure boundary components made of nickel alloy, stainless steel (including cast austenitic stainless steel), and steel (including steel with stainless steel cladding), including the reactor vessel, a limited number of internals components, and the reactor coolant system pressure boundary. The Inservice Inspection (ISI) Program also manages loss of material due to corrosion for reactor vessel internals components and reduction of fracture toughness due to thermal embrittlement of cast austenitic stainless steel pump casings and valve bodies.The Columbia Inservice Inspection (ISI) Program meets the requirements of ASME Section XI. The Columbia Inservice Inspection (ISI) Program details the requirements for the examination, testing, repair, and replacement of components specified in ASME Section Xl for Class 1, 2, or 3 components. The Columbia Inservice Inspection (ISI)Program complies with the ASME Code requirements, and is therefore consistent with the NUREG-1801 program. The program is described in FSAR Section 5.2.4 and is implemented by various plant procedures. The Columbia program scope has been augmented to include additional requirements, and components, beyond the ASME requirements. Examples include the augmentation of ISI to expanded reactor vessel feedwater nozzle examinations, examinations of high energy line piping systems that penetrate containment, and examinations per Generic Letter 88-01. Such augmentation is consistent with the ISI program description in NUREG-1801, Section XI.M1.The Columbia Inservice Inspection (ISI) Program contains a Risk-Informed Inservice Inspection (RI-ISI) program for Class 1 piping, based on EPRI Topical Report TR-1 12657 Revision B-A, which has been approved by the. NRC staff. The RI-ISI provides alternate inspection requirements for a subset of Class 1 piping welds. The staff's review of the RI-ISI program for the third ISI 10-year interval concluded that the program is an acceptable alternative to the current ISI program based on the American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section Xl requirements for Class 1, non-socket Category B-J welds. While this varies from the ASME Code, it represents a modernization of the Code that has been accepted by theNRC for use at. many nuclear power plants, including Columbia. Because of the widespread NRC acceptance of Risk-Informed ISI, this is not considered an exceptionto NUREG-1801. Evaluation of flaws in accordance with established site procedures using ASME Code and BWRVIP requirements may result in re-inspection or sample expansion.

All of these examinations and tests performed to date have satisfied the acceptance standards contained within Article IWE-3000, without exception. Currently, there are no containment surfaces or components requiring designation as augmented examination areas. Columbia's Mark II containment is inerted with nitrogen, which provides an atmosphere that is not conducive to corrosion of containment interior surfaces.

• Columbia Generating Station License Renewal Application Technical Information Exceptions to NUREG-1801 None.Required Enhancements None.Operating Experience The ISI Program -IWF refueling outage 18 (R-18) inspection identified non aging-related degradation such as a spring can setting out of tolerance.

This deficiency was further evaluated and accepted in accordance with the ISI program. Another deficiency found was one of the 1/2 inch bolts holding the installed shims in place sheared at a reactor pressure vessel (RPV) stabilizer. An engineering evaluation determined that the condition of the RPV stabilizer is acceptable. A condition report documents the discovery of this sheared bolt. Only one of the two 1/2 inch diameter bolts provided for shim restraint on each side is damaged (i.e., the upper bolt on the right hand side) and the associated shims are not dislodged, the condition does not affect the overall functionality of the RPV stabilizer. The damaged bolt was replaced during refueling outage 19 (R-19).Examinations were conducted of 100 percent of the locations specified in the program.There were two Code-related successive inspections required to be performed per Subsection IWF during the third interval first inspection period. These inspections, one on a snubber and one on a spring support, were performed during the R-19 outage andthe results were acceptable.The health of the ISI program is reported periodically in terms of performance indicators.

The program ensures that the oil environment in the mechanical systems is maintained to the required quality. The program manages the relevant conditions that could lead to the onset and propagation of a loss of material due to crevice, galvanic, general, or pitting corrosion or selective leaching, or reduction in heat transfer due to ,fouling, through monitoring of the lubricating oil consistent with manufacturer's recommendations and industry standards.

The relevant conditions are specific parameters including particulate and water content, viscosity, neutralization number, and flash point that are indicative of conditions that could lead to age-related degradation of susceptible materials. The Lubricating Oil Analysis Program is a mitigation program.The Lubricating Oil Analysis Program is supplemented by a one-time inspection of representative areas of lubricating oil systems under the Lubricating Oil Inspection to provide confirmation that loss of material and fouling are effectively mitigated. NUREG-1801 Consistency The Lubricating Oil Analysis Program is an existing Columbia program that, with enhancement, will be consistent with the 10 elements of an effective aging management program as described in NUREG-1801, Section XI.M39, "Lubricating Oil Analysis."

Aging Management Programs Page 8-145 January 2010 Columbia Generating Station License Renewal Application Technical Information Operating Experience The Lubricating Oil Analysis Program is, an ongoing program that effectively incorporates the best practices of the industry.

Manufacturer recommendations and industry standards are used to establish quality requirements for lubricating oil. The program incorporates the results of operating experience from Columbia and from other utility and industry sources. The program has been, and continues to be, subject to periodic internal and external assessment of the performance to identify strengths and areas for improvement. Review of Columbia operating experience did not reveal a loss of component intended function for components exposed to lubricating oil that could be attributed to an inadequacy of the Lubricating Oil Analysis Program. Abnormal lubricating oil conditions are promptly identified, evaluated, and corrected. For example, lubricating oil in the feedwater turbine has previously been found contaminated with water. The Lubricating Oil Analysis Program evaluated the condition, determined the source of the waterthrough sampling and analysis, and initiated corrective action. The lubricating oil was replaced and the source of the water leakage was repaired. In addition, levels of lead in emergency diesel generator lube oil have been found that exceeded the specified limits and showed an increasing trend. The evaluation determined the source to be soldered joints on the lube oil coolers. A planned replacement of the oil coolers with a different design was already in place at the time the source was determined, and the coolers have since been replaced.Conclusion The Lubricating Oil Analysis Program will manage loss of material and reduction in heat transfer for susceptible components in lubricating oil, through monitoring of the relevant parameters.

In addition, the program manages cracking for copper alloy > 15% Zn components in the Process Sampling System and for aluminum components in the HVAC systems that are subject to condensation.

The Open-Cycle Cooling Water Program consists of inspections, surveillances; and testing to detect the presence, and assess the extent, of fouling, loss of material, and cracking, combined with chemical treatments and cleaning activities to minimize fouling, loss of material, and cracking. The existing program is a combination condition monitoring and mitigation program that implements the recommendations of NRC GL 89-13, "Service Water System Problems Affecting Safety-Related Equipment." NUREG-1801 Consistency The Open-Cycle Cooling Water Program is an eXisting Columbia program that, with enhancement, will be consistent with the 10 elements of an effective aging management program as described in NUREG-1801 Section XI.M20, "Open-Cycle Cooling Water System," with exceptions. Exceptions to NUREG-1801 Program Elements Affected:

• Preventive Actions -NUREG-1801 states that system components are lined or coated to protect . underlying metal surfaces from being exposed to aggressive cooling water environments

.. Protective coatings on the inner walls are not used in the service water systems that are within the scope of license renewal at Columbia.

• Monitoring and Trending -NUREG-1801 states that testing and inspections are performed annually and during refueling outages. Inspection frequencies for the Open-Cycle Cooling Water Program are based on operating conditions and past history; flow rates, water quality, lay-up, and heat exchanger design .

No findings of significance with respect to the effectiveness of the existing program were identified during these integrated inspections. Furthermore, a review of plant-specific operating experience has identified several instances of damage due to erosion, designated as cavitation erosion. There have been repeated instances of leaks and failures in the SW System, which were cavitation-related. The design and operational adjustments have not fully precluded subsequent cavitation-related failures. That is, design and operational adjustments have corrected the issues sufficient to support continued operation of the plant, but have not fully eliminated the occurrence of cavitation erosion in the service water or attached systems. Therefore, in the course of normal operation during the period of extended operation, it is plausible that cavitation erosion could have the same effect as other forms of erosion (e.g., particulate) in the raw water environment of the service water and attached systems.Conclusion The Open-Cycle Cooling Water Program will detect and manage loss of material and reduction in heat transfer for susceptible components in raw water envir6nments.

• Columbia Generating StationLicense Renewal Application Technical Information Operating Experience Based on review of plant-specific and industry operating experience, the identified aging effects require management for the period of extended operation.

Industry operating experience: NUREG-1801 is based on industry operating experience through January 2005.Recent industry operating experience has been reviewed for applicability. Future operating experience is captured through the normal operating experience review process, which will continue through the period of extended operation. Stress corrosion cracking has occurred in other BWR reactor head closure studs as described in a GE service information letter.The Reactor Head Closure Studs Program detects aging effects using nondestructive examination (NDE) visual, surface and volumetric techniques to detect and characterize flaws. These techniques are widely used and have been demonstrated effective at detecting aging effects during inspections performed to meet ASME Section Xl Code requirements. A review of operating experience in recently submitted License Renewal Applications includes the following.

• Surface examination of RPV studs and nuts in 2001 at Cooper Nuclear Station during RE20 identified a recordable indication for RPV nuts, two non-recordable indications for RPV studs and a non-recordable for RPV washers.The recordable indication was evaluated as satisfactory.

Industry operating experience: NUREG-1801 is based on industry operating experience through January 2005. Recent industry operating experience has been reviewed for applicability. Future operating experience is captured through the normal operating experience review process, which will continue through the period of extended operation. Stress corrosion cracking has occurred in other BWR reactor head closure studs as described in a GE service information letter. The Reactor Head Closure Studs Program detects aging effects using nondestructive examination (NDE) visual, surface and volumetric techniques to detect and characterize flaws. These techniques are widely used and have been demonstrated effective at detecting aging effects during inspections performed to meet ASME Section XI Code requirements. A review of operating experience in recently submitted License Renewal Applications includes the following. . * . Surface examination of RPV studs and nuts in 2001 at Cooper Nuclear Station RE20 identified a recordable indication for RPV nuts, two recordable indications for RPV studs and a non-recordable for RPV washers. The recordable indication was evaluated as satisfactory.

The! Reactor Vessel Surveillance Program is a condition monitoring program developed in response to 10 CFR 50 Appendix H.The Columbia program is part of the BWRVIP Integrated Surveillance Program (ISP)that includes multiple BWR vessels. The BWRVIP ISP is an NRC-approved program that appropriately implements the requirements of Appendix H to 10 CFR Part 50.Testing and reporting done by the BWRVIP ISP is performed in accordance with the requirements of ASTM E 185 (1982). The NRC has approved the use of the BWRVIP ISP in place of a unique plant program for Columbia.

The BWRVIP ISP has been revised for License Renewal; as documented in BWRVIP-116, to ensure representative capsules are irradiated to fluence levels corresponding to the end of the period of extended operation. The BWRVIP ISP uses material surveillance capsules in BWR plants, as well as supplemental capsules irradiated in host plants, to provide data which bounds all operating BWR plants. No surveillance capsules from Columbia are included in the BWRVIP ISP; however, the Columbia surveillance, capsules will continue to be maintained in the reactor vessel in standby (deferred) status as required by the ISP.Capsules from host plants will be removed and tested in accordance with the ISP implementation plan defined in BWRVIP-86-A. Results from these tests that are applicable to Columbia will provide the necessary data to monitor embrittlement for the Columbia reactor pressure vessel (RPV). EN will apply the results of the ISP capsule testing to Columbia.The neutron fluence values used for the projections of neutron embrittlement effects are determined using NRC.-approved methodology. The exposure conditions of the reactor vessel are monitored to ensure that they continue to be consistent with those used to project the effects of embrittlement to the end of the license term. If the reactor vessel exposure conditions (neutron flux, spectrum, irradiation temperature, etc.) are altered, then the basis for the projection to 60 years is reviewed; and, if deemed appropriate, arevised fluence projection is prepared and the effects of the revised fluence analysis on neutron embrittlement calculations will be evaluated.The determination of neutron embrittlement effects for Columbia fully complies with NRC Regulatory Guide 1.99, Revision 2. Projections for neutron embrittlement effects have been adjusted to account for the specific nickel and copper contents of the Columbia materials. The extent of reactor vessel embrittlement for upper-shelf energy (USE) and adjusted reference temperature for nil-ductility transition (ART) is projected for 60 years in accordance with Regulatory Guide 1.99, Revision

NUREG-1801 ConsistEmcy The Service Air System Inspection is a new one-time inspection for Columbia that will be consistent with the 10 elements of an effective aging management program as described in NUREG-1 801, Section XI,M32, "One-Time Inspection." Exceptions to NUREG-1801 None. Aging Management Program Elements The results of an evaluation of each program element are provided below.

• Scope of Program The Service Air System Inspection detects and characterizes conditions relative to the following subject mechanical components to determine whether, and to what extent, degradation is occurring:
• Loss of material due to general corrosion on steel piping and valve bodies exposed to an air (internal) environment.

The Service Air System Inspection focuses on the portion of the Service Air System that forms the boundary for containment penetration X93 and the connected piping subject to an air (internal) environment (i.e., compressed air) that Aging Management Progr.ams Page 8-183 January 2010 Columbia Generating Station License Renewal Application Technical Information performs a structural integrity function. The Service Air System Inspection provides symptomatic evidence of loss of material (due to general corrosion).

• Preventive Actions No actions are taken as part of the Service Air System Inspection to prevent agingeffects or to mitigate aging degradation.

Parameters Monitored or Inspected The parameters to be inspected by the Service Air System Inspection include wall thickness or visual evidence of internal surface degradation, as measures of loss of material. Inspections will be performed by qualified personnel using established NDE techniques. Detection of Aging Effects The Service Air System Inspection will use a combination of established volumetric (radiographic or ultrasonic testing) and visual (VT-3 or equivalent) examination techniques performed by qualified personnel on a portion of the subject Service Air System components as determined by engineering evaluation, to identify evidence of a loss of material, or to confirm a lack thereof.The sample population will be determined by engineering evaluation based on sound statistical sampling methodology, and, where practical, 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 design margins.The Service Air System Inspection will be conducted within the 10-year period prior to the period of extended operation. Monitoring and Trending This one-time inspection activity is used to characterize conditions and determine if, and to what extent, further actions may be required. The activity includes increasing the inspection sample size and location if degradation is detected.Sample size 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 process to determine the need for subsequent aging management activities and for monitoring and trending of the results.Acceptance Criteria Indications or relevant conditions of degradation detected during the inspections will be compared to pre-determined acceptance criteria. If the acceptance criteria are not met, then the indications and conditions will be evaluated under the corrective Aging Management Programs Page B-184 January 2010 Columbia Generating Station License Renewal Application

The one-time inspection 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 CASS valve bodies. The Small Bore Class 1 Piping Inspection will be an evaluation and inspection with no actions to prevent or mitigate aging effects.This one-time inspection is applicable to small bore ASME Code, Class I piping components less than-4 inches nominal pipe size (NPS 4), which includes piping, fittings, branch connections, and valve bodies. The Small Bore Class 1 Piping Inspection includes visual and volumetric inspection of a representative sample of small bore Class 1 piping components. The inspection provides additional assurance that either age-related degradation of small bore ASME Code Class 1 piping components isnot occurring or that the aging is insignificant, such that an additional aging management program is not warranted during the period of extended operation. Columbia has not experienced cracking of small bore Class 1 piping solely due to stress corrosion or thermal and mechanical loading, and therefore this one-time inspection is appropriate. The inspection will include a representative sample of the small bore Class 1 piping population, and, where practical, will focus on the bounding or lead components most susceptible to aging due to time in service, severity of operating conditions, and lowest design margin. The guidelines of EPRI Report 1000701, "Interim Thermal Fatigue Management Guideline (MRP-24)" will be considered in selecting the sample size and locations. Actual inspection locations will be based on physical accessibility, exposure levels, NDE techniques., and locations identified in NRC Information Notice (IN) 97-46. Volumetric examinations (including qualified destructive and/or nondestructive techniques) will be performed by qualified personnel following procedures that are consistent with Section Xl of the ASME Code and 10 CFR 50, Appendix B.Unacceptable inspection findings will be evaluated by the Columbia corrective action process using criteria in accordance with the ASME Code. The evaluation of indications will include determining the extent of condition by the expansion of the sample size when called for by the Code.

• Columbia Generating Station License Renewal Application Technical Information Normal deterioration due to the effects of aging has been 'identified and effectivelymanaged under the site maintenance program.Visual examinations conducted by the Structures Monitoring Program have found general corrosion on steel components and concrete cracking, flaking, and scaling.Some of the currently identified concrete surface conditions have existed since original construction.

These conditions are the results of typical construction practices permitted by the original specifications and design criteria. They include small shrinkage cracks, minor construction joint voids, surface irregularities, and similar conditions determined to be minor degradation that did not require further evaluation. Inspected structures are in good condition and are capable of performing their design functions. Specific examples of age-related degradation identified by the Structures Monitoring Program include:* Circulating water pump house -Minor leaching observed on the concrete pad near the interface with the siding, cracks in the wall along joints due to stresses caused by a hanger attached to the wall above door, corrosion on the lower section of various door frames, and minor cracking of concrete damwork around the intake bays.* Turbine generator building -Air in-leakage noted at north exterior, turbine generator building wall panels, degraded roof membrane, and minor water in-leakage from roof above.* Radwaste control building -Some areas of concrete spalling in the switchgear rooms probably from racking breakers in and out, delaminated floor coatings, and punctured roof membrane from screws." Wetwell -Support steel has layer of corrosion products, condition was unchanged from previous inspections. The condition was reviewed by the material group which determined the condition of the wetwell and containment liner to be acceptable." Main steam tunnel -Some flaking of coating on the overhead horizontal panels, the condition was unchanged from previous inspections and determined to be acceptable. The overall Maintenance Rule program is comprised of many existing monitoring and assessment activities that collectively address potential and actual degradation conditions. The Maintenance Rule program screens all condition reports written at Columbia. When a condition report addresses a structure issue it is reviewed by a system engineer for evaluation of a functional failure. The screening resu}}
