ULNRC-05183 10 CFR 50.55a DAmeren DOCKET NUMBER 50-483 UNION ELECTRIC COMPANY CALLAWAY PLANT REQUESTS FOR RELIEF FROM ASME SECTION XI CODE INSERVICE EXAMINATION REQUIREMENTS Pursuant to 10 CFR 50.55a(g)(5)(iii) and/or 10 CFR 50.55a(a)(3), Union Electric Company (AmerenUE) hereby requests NRC approval of the attached relief requests (i.e., 10 CFR 50.55a requests) for the second 10-year interval of Callaway's Inservice Inspection (ISI) Program, which ended on December 18, 2005. The Code Edition(s) and Addenda applicable to Callaway's second 10-year ISI interval are ASME Section XI, "Rules for Inservice Inspection of Nuclear Power Plant Components," 1989 Edition, with no Addenda (and 1995 Edition with 1996 Addenda, as applicable).

The relief requests (identified as ISI-34, -35, -36, -37, -38, -39, -40, and -41) are provided as attachments to this letter. Each relief request constitutes an attachment except that ISI-36, -37, -38 and -39 are combined within one attachment using a tabular format due to the repetitive nature of these requests, in accordance with industry guidance (i.e., Nuclear Energy Institute white paper dated October 15, 2002,"Standard Format for Requests Pursuant to 10 CFR 50.55a").The relief requests pertain to implementation of ASME Section XI examination requirements for welds ultrasonically examined during the latter part of the second 10-year interval. (Most of the relief requests are for examinations performed during Refuel 13 which was conducted during the spring of 2004. ISI-40 and -41 are for welds examined during Refuel 14 which was conducted during the fall of 2005.) In each case, the requested relief primarily concerns the inability to obtain complete coverage of the applicable weld(s) in strict compliance with applicable requirements, as summarily explained below.X4Q4/7 a subsidiary of Ameren Corporation ULNRC-05183 October 25, 2006 Page 2 ISI-34 concerns examination of identified Class 1 piping welds from the outside/accessible surface of each weld. For these examinations, in lieu of strictly conforming with the requirements of 10 CFR 50.55a(b)(2)(xv)(A) and 10 CFR 50.55a(b)(2)(xvi)(B), AmerenUE requests the use of best available techniques, as qualified through the industry's Performance Demonstration Initiative (PDI), with demonstrated best effort for such single-side examinations, when applied from the accessible side of the weld.A similar request is being made for ISI-35 and ISI-40. ISI-35 concerns examination of a Class 2 flange-to-channel weld where the flange configuration necessitated a single-side examination, and ISI-40 is for austenitic pipe-to-valve and pipe-to-flange welds associated with the emergency core cooling system accumulators such that only single-side (50%) coverage could be attained for these welds as well. Best available techniques that have been demonstrated through PDI (for ASME Section XI, Appendix VIII, Supplement

2) are requested to be used from the accessible side of each weld.Relief requests ISI-36, ISI-37, ISI-38 and ISI-39 address examination of reactor vessel pressure (RPV) and/or RPV nozzle welds, for which 100% examination coverage could not be obtained in accordance with IWB-2500 (for the 1989 Edition of the Code, with no Addenda) due to obstructions and/or configuration restrictions.

AmerenUE proposes to accept the percent coverage attained for these welds. Relief request ISI-41 is a similar request except that it applies to two nozzle welds associated with the reactor coolant system pressurizer.

Supporting information and justification for each request is provided in each of the applicable attachments.

It may be noted that no new regulatory commitments have been made or identified pursuant to this letter and its attachments.

Please contact us for any questions you may have regarding these relief requests.Sincerely,Keith D. Young Manager -Regulatory Affairs TBE/jdg ULNRC-05183 October 25, 2006 Page 3 Attachments:

In fact, the Code Item for all 8 welds is R-A, in accordance with the RI-ISI program.2. ADplicable Code Edition and Addenda S S ASME Section XI, 1989 Edition, with no Addenda.ASME Section XI, 1995 Edition 1996 Addenda.3. Apiplicable Code Requirement These welds were selected for the Risk-Informed Inservice Inspection (RI-ISI) Program[References 8.1 and 8.2]. The specific locations selected were based upon the Degradation Mechanism (DM) evaluation, Consequence Evaluation and Expert Panel insights (Element Selection).

A volumetric ultrasonic examination (UT) is the prescribed examination method.The Revised Risk-Informed Inservice Inspection Evaluation Procedure

[Reference 8.3]Page 1 of 7 10 CFR 50.55a Request Number ISI-34 provides examination volumes based upon specific degradation mechanisms.

For cases where no degradation mechanism was identified, the thermal fatigue examination volume is chosen as a default volume. The thermal fatigue examination volume applies to all of the welds as shown in Table 2.Weld No. Degradation Mechanism 2-BB-04-F004 NONE 2-BB-02-F019 THERMAL FATIGUE 2-BG-24-FW061 THERMAL FATIGUE 2-BG-24-FW062 THERMAL FATIGUE 2-BG-24-FW067 NONE 2-BG-02-S046-A NONE 2-BG-02-S046-C NONE Table 2, Weld list showing degradation mechanism Appendix VIII, Supplement 2 applies to Wrought Austenitic Piping Welds. 10 CFR 50.55a(b)(2)(xv)(A), requires the following examination coverage when applying Supplement 2 to Appendix VIII: (1) Piping must be examined in two axial directions and when examination in the circumferential direction is required, the circumferential examination must be performed in two directions, provided access is available.

(2) Where examination from both sides is not possible, full coverage credit may be claimed from a single side for ferritic welds. Where examination from both sides is not possible on austenitic welds, full coverage credit from a single side may be claimed only after completing a successful single sided Appendix VIII demonstration using flaws on the opposite side of the weld.10 CFR 50.55a(b)(2)(xvi)(B), requires that examinations performed from one side of a ferritic or stainless steel pipe weld must be conducted with equipment, procedures, and personnel that have demonstrated proficiency with single-side examinations.

To demonstrate equivalency to two sided examinations, the demonstration must be performed to the requirements of Appendix VIII as modified by this paragraph and 10 CFR 50.55a(b)(2)(xv)(A).

4. Impracticality of Compliance The Final Rule requires that if access is available, the weld shall be scanned in each of the four directions (parallel and perpendicular to the weld); where scanning from one side is impractical, coverage credit may be taken for single side exams on ferritic piping.However, for austenitic piping, a procedure must be qualified with flaws on the Page 2 of 7 10 CFR 50.55a Request Number ISI-34 inaccessible side of the weld. There are currently no qualified single side examination procedures that demonstrate equivalency to two-sided examination procedures on austenitic piping welds. Current technology is not capable of reliably detecting or sizing flaws on the far side of an austenitic weld for configurations common to US nuclear applications.

The PDI Program conforms with the Final Rule regarding single-side access for piping.PDI Performance Demonstration Qualification Summary (PDQS) certificates for austenitic piping list the limitation that single-side examination is performed on a best effort basis. The best effort qualification is provided in place of a complete single-ide qualification to demonstrate that the examiners qualification and the subsequent weld examination is based on application of the best available technology.

When the examination area is limited to one side of an austenitic weld, examination coverage does not comply with 10 CFR 50.55a(b)(2)(xv)(A) and proficiency demonstrations do not comply with 10 CFR 50.55a(b)(2)(xvi)(B) and full coverage credit may not be claimed.Description of Coverage Limitations Weld No. Coverage Achieved Limitation 2-BB-04-F004 50% Pipe to valve weld with limited access to the valve side. The weld configuration obstructs 100% of one circ and one axial scan.2-BB-02-FO19 50% Pipe to valve weld with limited access to the valve side. The weld configuration obstructs 100% of one circ and one axial scan.2-BG-24-FW061 50% The examination is limited to one side due to OD configuration.

The pipe and the pup piece are of different thickness.

The circ and axial scan are 100%obstructed from one side.2-BG-24-FW062 83.5% Weld is obstructed on one side due to lift off in crotch area of tee. The length of the obstruction is 2.5" and obstructs 33%of the axial scan and 33% of the circ scan on one side of the weld. All other scans are complete.Page 3 of 7 10 CFR 50.55a Request Number ISI-34 Weld No. Coverage Achieved Limitation 2-BG-24-FW067 83.5% Weld is obstructed on one side due to lift off in crotch area of tee. The length of the obstruction is 2.5" and obstructs 33%of the axial scan and 33% of the circ scan on one side of the weld. All other scans are complete.2-BG-02-S046-A 50% Pipe to Tee weld. Considered 50%coverage due to geometry of tee.Performed best effort examination of both sides of weld.2-BG-02-S046-C 50% Tee to Pipe weld. Considered 50%coverage due to geometry of tee.Performed best effort examination of both sides of weld.In all the examinations, a best effort examination using all available ultrasonic techniques of the obstructed portions of the weld was performed.

Coverage was not claimed, however, for any portion of any examination that did not meet with Appendix VIII, PDI, and 10 CFR 50.55a requirements.

For 2-BG-24-FW062 and 2-BG-24-FW067, the examination coverage reports are attached to show how 83.5% coverage was obtained.

For the remaining welds listed, single-sided access resulted in 50% coverage being obtained (i.e., the examination could claim coverage of only one side, therefore only 2 of the required 4 scan paths could be claimed for 50% total coverage.).

5. Burden Caused by Compliance There are currently no qualified single side examination procedures that demonstrate equivalency to two-sided examination procedures on austenitic piping welds. Current technology is not capable of reliably detecting or sizing flaws on the far side of an austenitic weld for configurations common to US nuclear applications.

The locations chosen for the RI-ISI program were based upon sound engineering judgment.

Component-to-pipe welds were preferentially chosen because at those locations, the worse case thermal fatigue conditions exist for that pipe segment. It was known at the time of selection that a conflict existed between the required weld volume and ultrasonic inspection qualification (PDI rules). Callaway chose these locations, based upon degradation mechanism issues because it was believed that these were the right locations to examine.Degradation Mechanism Assessment of Examination Coverage Limitation:

Currently, ASME Section XI is developing a Code Case to address issues relating to coverage of RI-ISI selected welds. The Code Case number is N-7 11 and is entitled Page 4 of 7 10 CFR 50.55a Request Number ISI-34"Alternative Examination Coverage Requirements for Examination Category B-F, B-J, C-F-i, C-F-2, and R-A Piping Welds." The purpose of Code Case N-711 is to provide examination coverage requirements that are consistent with the degradation mechanism area of interest.N-7 11, as currently written, requires the Owner to determine the damage mechanism associated with the weld. From this damage mechanism assessment an acceptable alternative extent of examination coverage is determined.

The diagram on the next page (page 6) shows the areas of interest for Pipe to Component Welds which have been identified with either Thermal Fatigue (TT or TASCS) or NONE as a degradation mechanism.

This diagram was developed based upon Table 2 of Code Case N-711.Using the degradation mechanism insight of Code Case N-711 and its associated white paper, Callaway Plant could take credit for examining 100% of the area of interest for the subject welds.Consequence Assessment of Coverage Limitation:

As an independent assessment of the impact of the examination coverage limitations on the Inservice Inspection program, Callaway Plant performed a risk impact analysis per the requirements of Section 3.7 of EPRI TR-1 12657. The calculations are based on the conservative assumption that no coverage was achieved even though, as described above, the volumes of interest for the appropriate degradation mechanism were examined.

The results of the delta risk calculation are shown in the table below.The net change in CDF and LERF as a result of removing these locations from the examination program was determined to be 1.8E-9 and 2.3E-10, respectively.

This result demonstrates that the impact of not examining these locations is insignificant.

Again, it should be noted that the areas of interest were examined and therefore the risk impact is in reality, orders of magnitude less than these already insignificant values.6. Proposed Alternative and Basis for Use The best available techniques, as qualified through the Performance Demonstration Initiative for Supplement 2 with demonstrated best effort for single-side examination, are used from the accessible side of the weld.7. Duration of Proposed Alternative Callaway Plant requests that the proposed alternative be approved for the remainder of the Second Inservice Inspection Interval.Page 5 of 7 10 CFR 50.55a Request Number ISI-34 Damage Mechanisms:

Applicable Code Edition and Addenda* ASME Section XI, "Rules for Inservice Inspection of Nuclear Power Plant Components," 1989 Edition, with no Addenda.3. Applicable Code Requirement 100% weld coverage in accordance with Figure No. IWC-2500-1.

4. Impracticality of Compliance The stainless steel flange configuration caused the examination to be single-sided.

The examination was further obstructed by flange bolting. An additional 45-degree full-vee shear wave examination and a 45-degree half-vee longitudinal wave examination were performed to address the flange side of the weld. Conservatively, however, no credit was taken for the flange side of the weld because single-sided examinations of austenitic welds have not been adequately demonstrated in accordance with the requirements of ASME Section XI Appendix VIII. A copy of the examination report for the weld is attached.5. Burden Caused by Compliance There are currently no qualified single-side examination procedures that demonstrate equivalency to two-sided examination procedures on austenitic welds. Current technology is not capable of reliably detecting or sizing flaws on the far side of an Page 1 of 2 10 CFR 50.55a Request Number ISI-35 austenitic weld for configurations common to US nuclear applications.

Plant modifications or replacement with components designed to allow for complete coverage would be needed to meet the ASME Code requirements.

This would impose a considerable burden to Callaway Plant.6. Proposed Alternative and Basis for Use The best available techniques, similar to those qualified through the industry's Performance Demonstration Initiative for Supplement 2 with a demonstrated best effort for single-side examination, are used from the accessible side of the weld.7. Duration of Proposed Alternative Callaway Plant requests that the proposed alternative be approved for the remainder of the Second Inservice Inspection Interval.Page 2 of 2 SSCIENTECH INCOMPLETE EXAMINATION REPORT REPORT NO: 0 Y/o PAGE OF ID PROCEDURE:

1. ASME Code Components Affected Refer to Table 1, Columns 1 and 2.2. Applicable Code Edition and Addenda ASME Section XI, "Rules for Inservice Inspection of Nuclear Power Plant Components," 1989 Edition, with no Addenda.3. Applicable Code Requirement Refer to Table 1, Column 3.4. Impracticality of Compliance A. The Lower Torus to Dollar Plate weld is positioned at about the same elevation as the peripheral bottom-mounted instrumentation (BMI) tubes. Scanning was conducted between obstructing penetrations with the scan boundaries maximized by visually assisted position of the exam head so that scan starts and stops were as close to the tubes as tool configuration allowed. Final examination coverage was estimated at 74.2%.B. The Lower Shell to Lower head circumferential weld is limited in scanning due to the proximity of six core support lugs. Scanning was conducted between and below the obstructing lugs with the scan boundaries maximized by visually assisted positioning of the exam head so that scan starts and stops were as close to the support lugs as tool configuration allowed. Final examination coverage was estimated at 77.3%.C. The Inlet Nozzle Safe-end to Elbow welds are limited in examination coverage for the detection of axial flaws (circumferential scans), as per the PDI-issued Performance Demonstration Qualification Summary (PDQS) document, due to the ID configuration (field weld root geometry).

Areas of limitation were fully examined by supplemental visual (enhanced VT) and Eddy Current techniques.

Final ultrasonic examination coverage was estimated at 50.0% (since coverage credit is taken for axial scans only).D. Callaway Plant obtained 100% coverage for reflectors parallel to the weld seam by a combination of radial scan paths (Star scans) and scans from within the nozzle bore (Bore scans). However, the proximity of the nozzle protrusion or boss to the Outlet Nozzle to Shell welds limits the parallel scans from the vessel ID (Tangential scans).Because of this, limited coverage of 58.6% was achieved examining for transverse reflectors.

Combined final ultrasonic examination coverage was estimated at 79.3%.Page 1 of 3 10 CFR 50.55a Request Numbers ISI-36, ISI-37, ISI-38, and ISI-39 5. Burden Caused by Compliance The design configuration/restriction makes the Code-required examination coverage requirements impractical.

Plant modifications or the replacement of components designed to allow for complete coverage would be needed to meet the ASME Code requirements.

This would impose a considerable burden to Callaway Plant.6. Proposed Alternative and Basis for Use Callaway proposes to accept the percent coverage obtained on the subject examinations.

The best-effort examination approach, in addition to the other considerations or actions described below, provides reasonable assurance of safety and/or structural integrity.

For the Inlet Nozzle Safe-end to Elbow welds, Callaway performed supplemental eddy current and enhanced visual examinations.

The reactor vessel shell welds are constructed of low alloy steel, and the Inlet Nozzle Safe-end to Elbow welds are constructed of stainless steel materials.

These materials have been shown to be resistant to stress corrosion cracking in pressurized water environments.

There is no degradation mechanism, other than fatigue, active in the subject welds that would cause weld failure." VT-2 examinations performed in conjunction with system pressure testing each refueling, along with reactor coolant system leak rate limitations imposed by the plant's Technical Specifications, as well as containment atmospheric particulate radioactivity monitoring, provide additional assurance that a leak would be detected prior to any gross failure occurring.

7. Duration of Proposed Alternative Callaway Plant requests the above Proposed Alternative be accepted for the duration of the second inservice inspection interval.Page 2 of 3 10 CFR 50.55a Request Numbers ISI-36, ISI-37, ISI-38, and ISI-39 Table 1 -Repetitive/Duplicative Requests Requested in Accordance with 10 CFR 50.55a(g)(5)(iii), Inservice Inspection Impracticality Second 1 0-Year Interval -Inservice Inspection Program ASME Code Section XI, "Rules for Inservice Inspection of Nuclear Power Plant Components," 1989 Edition, with no Addenda 1. 2. 3. 4. 5. 6. 7.ASME CODE PROPOSED COMPONENT APPLICABLE CODE ALTERNATIVE DURATION OF REQUEST (AREA OR WELD COMPONENT ID REQUIREMENT (100% IMPRACTICALITY BURDEN CAUSED AND BASIS FOR PROPOSED NUMBER TO BE EXAMINED)

Only 50% volume coverage can be claimed for these exams. (The welds that were subject to PSI as shown in the table above are new welds due to a modification that was completed during Refuel 14.These welds are associated with the Accumulator Safety Injection system.)2. Applicable Code Edition and Addenda ASME Code Section XI -1989 Edition, Appendix VIII of Section XI, 1995 Edition with the 1996 Addenda 3. Applicable Code Requirement 10 CFR 50.55a(b)(2)(xv)(A), requires the following examination coverage when applying Supplement 2 to Appendix VIII: (1) Piping must be examined in two axial directions and when examination in the circumferential direction is required, the circumferential examination must be performed in two directions, provided access is available.

Page 1 of 3 10 CFR 50.55a Request Number ISI-40 (2) Where examination from both sides is not possible, full coverage credit may be claimed from a single side for ferritic welds. Where examination from both sides is not possible on austenitic welds, full coverage credit from a single side may be claimed only after completing a successful single-sided Appendix VIII demonstration using flaws on the opposite side of the weld.10 CFR 50.55a(b)(2Xxvi)(B) requires that examinations performed from one side of a ferritic or stainless steel pipe weld must be conducted with equipment, procedures, and personnel that have demonstrated proficiency with single-side examinations.

To demonstrate equivalency to two-side examinations, the demonstration must be performed to the requirements of Appendix VIII as modified by this paragraph and 10 CFR 50.55a(b)(2)(xv)(A).

4. Impracticality of Compliance As stated above, 10 CFR 50.55a(b)(2)(xv)(A) requires that if access is available, the weld shall be scanned in each of the four directions (parallel and perpendicular to the weld). Full coverage credit may be taken for single-side exams on ferritic piping (when examination from both sides is not possible).

However, for full coverage credit from a single side for austenitic piping, a procedure must be qualified with flaws on the inaccessible side of the weld. There are currently no qualified single-side examination procedures that demonstrate equivalency to two-side examination procedures on austenitic piping welds. Current technology is not capable of reliably detecting or sizing flaws on the far side of an austenitic weld for configurations common to US nuclear applications.

The industry-established Performance Demonstration Initiative (PDI) Program addresses 10 CFR 50.55a(b)(2)(xv)(A) requirements regarding single-side access for piping. PDI Performance Demonstration Qualification Summary (PDQS) certificates for austenitic piping list the limitation that single-side examination is performed on a best-effort basis. The best-effort qualification is provided in place of a complete single-side qualification to demonstrate that the examiner's qualification and the subsequent weld examination is based on application of the best available technology.

When the examination area is limited to one side of an austenitic weld, examination coverage does not comply with 10 CFR 50.55a(b)(2)(xv)(A) and proficiency demonstrations do not comply with 10 CFR 50.55a(b)(2)(xvi)(B).

Full coverage credit cannot therefore be claimed.5. Burden Caused by Compliance There are currently no qualified single-side examination procedures that demonstrate equivalency to two-side examination procedures on austenitic piping welds. Current technology is not capable of reliably detecting or sizing flaws on the far side of an austenitic weld for configurations common to US nuclear applications.

Page 2 of 3 10 CFR 50.55a Request Number ISI-40 6. Proposed Alternative and Basis for Use The best available techniques, as qualified through the PDI for Supplement 2 with a demonstrated best effort for single-side examination, are to be used from the accessible side of the weld (in lieu of complete or strict compliance with Appendix VIII requirements).

7. Duration of Proposed Alternative The remainder of the 2 nd 10-year inservice inspection interval.Page 3 of 3 10 CFR 50.55a Request Number ISI-41 Relief Requested in Accordance with 10 CFR 50.55a(g)(5)(iii)

Applicable Code Edition and Addenda ASME Code Section XI -1989 Edition 3. Aipplicable Code Requirement For Examination Category B-D, Item B3.1 10, IWB-2500 requires 100% volumetric examination of nozzle-to-shell welds as defined in Figure IWB-2500-7(b)

4. Impracticality of Compliance The design configuration of the subject nozzle-to-head welds precludes ultrasonic examination of essentially 100% of the required examination volume. In order to examine the welds in accordance with the code requirements, the pressurizer would require extensive design modifications.

The physical arrangement of TBB03-1OC-W, in conjunction with the close curvature of the outside wall surfaces of the nozzle does not allow for a complete examination from the nozzle side. Scans normal to the weld from the head side were essentially 100% complete.Similarly, the physical arrangement of 2-TBB03-1OA-W, in conjunction with the close curvature of the outside wall surface of the nozzle does not allow for a complete examination from the nozzle side. For scans normal to the weld on the bottom vessel head side, examinations are limited to areas approximately 1.5" from the weld toe.Limitations on the bottom head side of 2-TBB03-1OA-W are due to the presence of immersion heaters penetrating the head which restricts the scanning surface of the transducers.

The weld configurations and the exact coverage achieved for each required scan are detailed in the attached ultrasonic examination reports.5. Burden Caused by Compliance Performance of an ultrasonic volumetric examination 100% of full penetration welds in the pressurizer nozzle-to-head welds would be impractical.

AmerenUE has Page 1 of 2 10 CFR 50.55a Request Number ISI-41 determined that it would be impractical to attempt other volumetric examination in order to increase examination coverage.6. Proposed Alternative and Basis for Use In lieu of the Code-required 100% ultrasonic examination, an ultrasonic examination was performed on accessible areas to the maximum extent practical.

Ultrasonic examination of the subject welds to the maximum extent practical still provides assurance of an acceptable level of quality and safety. Significant degradation, if present, would have been detected during the ultrasonic examination that was performed on the subject welds.7. Duration of Proposed Alternative The remainder of the 2 n, I 0-year inservice inspection interval.Page 2 of 2 a"-AmerenUE Summary No.: Workscope:
