ISI Relief Request No. 21 (Rev. 0), Prairie Island Unit 2, 3rd Interval Limited Examination SYSTEM: Various CLASS: 1 and 2 CATEGORY: Various ITEM NO: Various Impractical Examination Requirements:

American Society of Mechanical Engineers (ASME) Section Xl (1989 Edition, no addenda)

Code requires full examination coverage of inservice inspection (ISI) components per Table IWB-2500-1, and IWC-2500-1. NRC Regulatory Guide 1.147 endorses the use of Section Xl Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds." This code case allows greater than 90% coverage of a weld to meet the "essentially 100%"

requirement.

In addition, NRC Information Notice 98-42 "Implementation of 10 CFR 50.55a(g) Inservice Inspection requirements" dated Dec. 1, 1998, states, "The NRC has adopted and further refined the definition of 'essentially 100 percent' to mean 'greater than 90 percent' in 10 CFR 50.55a(g)(6)(ii)(A)(2) for required examination coverage of reactor pressure vessel welds.

This standard has been applied to all examination of welds or other areas required by ASME Section Xl."

The Prairie Island construction permit was issued in 1967. This facility was designed and constructed with limited accessibility due to component configurations and/or physical barriers for which 100% examination coverage is not achievable on some ISI components examined for the Third Ten Year Interval.

Basis for Relief:

This request is submitted pursuant to 10 CFR 50.55a(g)(5)(iv) which states, 'Where an examination requirement by the code or addenda is determined to be impractical by the licensee and is not included in the revised inservice inspection program as permitted by paragraph (g)(4) of this section, the basis for this determination must be demonstrated to the satisfaction of the Commission."

The regulation further states in 10 CFR 50.55a(g)(1) that, "For a boiling or pressurized water-cooled nuclear power facility whose construction permit was issued before January 1, 1971, components (including supports) must meet the requirements of paragraphs (g) (4)and (g)(5) of this section to the extent practical." 10 CFR 50.55a(g)(4) states, "Throughout the service life of a boiling or pressurized water-cooled nuclear power facility, components (including supports) which are classified as ASME Code Class 1, Class 2, and Class 3 must meet the requirements, except design and access provisions and preservice examination requirements, set forth in Section Xl of editions of the ASME Boiler and Pressure Vessel Code ... to the extent practical within the limitations of design, geometry and materials of construction of the components."

1 of 7

ISI Relief Request No. 21 (Rev. 0), Prairie Island Unit 2, 3rd Interval Prairie Island was designed and constructed prior to development of ASME Xl, therefore design for accessibility and inspection coverage is not in many cases, sufficient to permit satisfying the current Code requirements. Limitations to inspections are primarily due to design obstructions, component configurations and interference. In the case of circumferential welds a limitation from ultrasonic examination may exist simply because of weld joint configuration as with a pipe to valve or fitting weld.

A summary of the limited examinations are described below and also included in Table 1, "Limited Examinations - Prairie Island Unit 2 - 2005 Refueling Outage."

Part A: Category B-D, "Full Penetration Welds of Nozzles in Vessels" Reactor Vessel (RV) Nozzle (N-7), Outlet Nozzle to Vessel Loon A:

The Reactor Vessel Nozzle-to-Vessel weld is subject to a volumetric examination.

The volumetric examination was performed using personnel and procedures qualified in accordance with Appendix Vill, Supplements 4,6 and 7. The examination was conducted using 45-degree transducers. The nozzle and vessel material are SA 508.

The examination was limited in both the parallel and perpendicular scans from the vessel ID to 78.56% due to the proximity of the outlet nozzle protrusion to the nozzle to shell weld. As an alternative to the ultrasonic examination, radiography was considered and determined to be an unacceptable substitute due to no outside access and weld configuration.

The following supporting documentation has been provided:

ISI Relief Request No. 21 (Rev. 0), Prairie Island Unit 2, 3rd Interval Reactor Vessel (RV) Nozzle (N-8), SI Nozzle to Vessel Loop A:

The Reactor Vessel Nozzle-to-Vessel weld is subject to a volumetric examination.

The volumetric examination was performed using personnel and procedures qualified in accordance with Appendix VIII, Supplements 4, 6, and 7. The examination was conducted using 45-degree transducers. The nozzle and vessel material are SA 508.

The examination was limited in both the parallel and perpendicular scans from the vessel IDto 59.26% due to the proximity of the outlet nozzle protrusion to the nozzle to shell weld. As an alternative to the ultrasonic examination, radiography was considered and determined to be an unacceptable substitute due to no outside access and weld configuration.

The following supporting documentation has been provided: , [SI Drawing 2-lSI-40 , Examination Report Number 2005VE023 and WesDyne report Reactor Vessel (RV) Nozzle (N-I1), SI Nozzle to Vessel Loop B:

The Reactor Vessel Nozzle-to-Vessel weld is subject to a volumetric examination.

The volumetric examination was performed using personnel and procedures qualified in accordance with Appendix ViII, Supplements 4, 6, and 7. The examination was conducted using 45-degree transducers. The nozzle and vessel material are SA 508.

The examination was limited in both the parallel and perpendicular scans from the vessel IDto 59.26% due to the proximity of the outlet nozzle protrusion to the nozzle to shell weld. As an alternative to the ultrasonic examination, radiography was considered and determined to be an unacceptable substitute due to no outside access and weld configuration.

The following supporting documentation has been provided: ISI Drawing ISI-40 , Examination Report Number 2005VE024 and WesDyne report Part B: Category B-F, "Pressure Retaining Dissimilar Metal Welds" Reactor Coolant (RC) Weld (W-5), Nozzle to Safe End:

This dissimilar metal weld joint configuration is not currently covered by the demonstrated samples at the Electric Power Research Institute (EPRI) Perf6rmance Demonstration Initiative (PDI) center. Due to the design of the joint, no mockup could be created to examine this ultrasonically to meet Appendix VIII, Supplement 10.

3 of 7

ISI Relief Request No. 21 (Rev. 0), Prairie Island Unit 2, 3rd Interval Therefore a supplemental ultrasonic (UT) exam was performed with the following results:

The Elbow to Safe End weld is subject to a volumetric examination and surface examination. The volumetric examination was performed using personnel and procedures qualified in accordance with Appendix ill. The examination was conducted using 45-degree refracted longitudinal transducers. The elbow and safe end material are SA 351-CF8 cast austenitic stainless and 308L stainless (this joint contains no Alloy 82/182 or 600). The examination was limited to 78.46% due to the OD profile of the cast stainless steel elbow. The UT examination is further hindered from the elbow side of the weld for obtaining meaningful ultrasonic data because of the elbow material being cast austenitic stainless steel. UT sound beam attenuation and propagation properties in cast stainless steel are extremely difficult. The ASME Code Committee and the industry Performance Demonstration Initiative (PDI) recognized that such examinations are difficult. ASME Section Xl, Appendix VIII, Supplement 9 has been in "course of preparation" for several years, hence, there are no qualified examination procedures or personnel to conduct the required examinations. As an alternative to the ultrasonic examination, radiography was considered and determined to be an unacceptable substitute due to radiological constraints, the reactor vessel level would be required to be at reduced inventory below the center line of the hot leg, weld configuration, and the undue hardship imposed without offering any commensurate increase in safety with cost benefit.

The required surface examination was performed using liquid penetrant and was not limited. 100% of the required surface area was inspected (Inspection Report No.

2005P032). No relevant indications were detected.

The weld is included in the boundary examined by VT-2 during pressure testing (SP 2070, Reactor Coolant System Integrity Test, completed on 619/2005). No leakage was identified in the vicinity of the weld.

The following supporting documentation has been provided: , ISI Drawing 2-lSI-33A , Examination Report Number 2005U036 Part C: Category B-J, "Pressure Retaining Welds in Piping" Residual Heat Removal (RH) Weld (W-11) Valve to Pipe:

This piping weld is subject to be examined by both volumetric and surface examination methods. The volumetric examination was performed using personnel and procedures qualified in accordance with Appendix VIII, Supplement 2. The examination was conducted using 45 and 60-degree transducers. The valve and piping material are austenitic stainless steel. The examination is limited to 50% in both the axial and circumferential directions from the piping side of the weld due to the weld joint configuration connection to the valve. The credited volumetric examination of the Weld 4 of 7

ISI Relief Request No. 21 (Rev. 0), Prairie Island Unit 2, 3rd Interval Required Volume (WRV) was limited to 47.77% and only a single-sided examination could be performed. It should be noted that the volumetric examination was performed through 100% of the Code WRV; however, the PDI Appendix Vill procedure used is not qualified for the detection of flaws on the far side of single sided access examinations on austenitic stainless steel piping welds. The techniques employed for the examination provide for a best effort examination. As an alternative to the ultrasonic examination, radiography was considered and determined to be an unacceptable substitute due to radiological constraints, weld configuration, and the undo hardship imposed without offering any commensurate increase in safety with cost benefit.

The required surface examination was performed using liquid penetrant and was not limited. 100% of the required surface area was inspected (Inspection Report No.

2005P019). No relevant indications were detected.

The weld is included in the boundary examined by VT-2 during pressure testing (SP 2070, Reactor Coolant System Integrity Test, completed on 6/9/2005). No leakage was identified in the vicinity of the weld.

The following supporting documentation has been provided: , ISI Drawing 2-ISI-1 OA , Examination Report Numbers 2005U024 Part D: Category C-F-2 "Pressure Retaining Welds in Carbon or Low Alloy Steel Piping" Main Steam (MS) Weld (W-14), Tee to Flange:

This tee to flange pipe weld is subject to be examined by both volumetric and surface examination methods. The reducer tee and pipe materials are carbon steel. The volumetric examination was performed using personnel and procedures qualified in accordance with Appendix VilI, Supplement 3. The examination was conducted using 45 and 60-degree transducers. The piping materials are A155 KC70 . The credited volumetric examination of the WRV was limited to 74.85%. As an alternative to the ultrasonic examination, radiography was considered and determined to be an unacceptable substitute due to radiological constraints, weld configuration, and the undo hardship imposed without offering any commensurate increase in safety with cost benefit.

The required surface examination was performed using Dye Penetrant and 95.8% of the required surface area was inspected (Inspection Report No. 2005P043). No relevant indications were detected.

ISI Relief Request No. 21 (Rev. 0), Prairie Island Unit 2, 3rd Interval The weld is included in the boundary examined by VT-2 during pressure testing (SP 2168.1 1, completed 9/13/2003). No leakage was identified in the vicinity of the weld.

The following supporting documentation has been provided:

Attachment 10, ISI Drawing 2-lSI-47B Attachment 11, Examination Report Number 2005U023 Additional Means of Establishing Component Integrity:

System integrity is monitored during normal operation by many direct and indirect methods, e.g., containment radiation monitoring, containment air monitoring, containment sump monitoring, containment temperature monitoring, system walk downs, surveillance testing, etc.

Alternate Examination:

The limitations have been noted on the ISI examination reports and are included in the 2005 ISI Outage Summary Report. NMC will continue to document limitations.

All in-service inspections at Prairie Island Unit 2 have been completed to the greatest extent practical. When limitations to required inspections are encountered, Prairie Island's "Limitations to NDE" procedure SWI NDE-LTS-1 was applied. SWI NDE-LTS-1 (Attachment

12) is used when an ASME Section XI Code required examination results in less than 90%

coverage. It requires a review of the procedures to obtain maximum coverage and documentation of the limitation. The procedure also examines whether an alternative method could be used to obtain better coverage as allowed by the Code. This procedure was used for all the items identified above and the maximum inspection coverage was achieved.

Limitations are due to design, geometry, and materials of construction of the components.

NMC will continue to utilize the most current techniques available for future examinations.

________________ .;..Page 2 of 13 1.0 PURPOSE This procedure provides instruction for identifying, quantifying and recording of limitations encountered while performing NDE examinations under the ISI program.

2.0 REFERENCES

This procedure complies with the applicable portions of the following referenced documents:

2.1 Nuclear Regulatory Commission Regulatory Guide - 1.150 "Ultrasonic Testing of Reactor Vessel Welds during Preservice and Inservice Examinations", (Rev. 1 dated Feb. 1983).

2.2 Code case N-460 - Alternative Examination Coverage for Class 1 and Class 2 Welds - Section Xl, Division 1.

2.3 Procedure SWI NDE-NDE-1, 'Equipment, Personnel and Material Reporting."

2.4 5AWI 14.6.0 "ISI Examination Program" 3.0 APPLICABILITY 3.1 This procedure is applicable to examinations performed at Prairie Island Nuclear Generating Plant.

3.2 This procedure is to be followed when it has been determined that there is a limitation which prevents obtaining full coverage of an area or volume as stated by the applicable examination procedure.

For ultrasonic examinations, this would mean less than all of the required scans and/or a reduction of required scan path for one or more scans.

SWI NDE-LTS-1 LIMITATIONS TO NDE REV: 1

______________ -iPage _ 3 of 13 4.0 DEFINITIONS 4.1 Limitation - something that limits, restraint: An obstacle to the performance of an examination procedure.

4.2 Evaluation - to determine the significance, worth, or condition of, usually by careful appraisal and study.

4.3 Practical -" of, relating to, or manifested in practice or action: not theoretical or ideal; concerned with voluntary action and ethical decisions. Useful." For this application this is interpreted to mean, for a specific case the benefits of a proposed action outweigh the negative aspects of that action.

5.0 PREREQUISITES Personnel Requirements 5.1 Examination personnel certification and eye examinations SHALL be documented in accordance with SWI NDE-NDE-1.

5.2 Nondestructive examination personnel SHALL be certified to a minimum of Level I in the appropriate method to operate equipment and Level II to interpret test results.

6.0 EQUIPMENT This item is not applicable to this procedure. If alternate methods are required to augment coverage, that work SHALL be done under a separate procedure.

SWI NDE-LTS-1 LIMITATIONS TO NDEREV:

___ Page 4 of 13 7.0 INSTRUCTIONS 7.1 Initial Examination Where the examiner is not able to complete a full examination as dictated by applicable procedure, the following steps SHALL be taken:

7.1.1 Complete original examination on accessible portions.

7.1.2 Make sketch which includes dimensions defining location and size of limitations using a report format similar to that shown in Figure 3.

7.1.3 Describe the limitation including what it is and how it interferes with the exam. State what appears to be required to remove the limitation using a report format similar to that shown in Figure 3.

7.1.4 For volumetric examinations, construct a surface profile using a surface contour gauge and perform a thickness profile (typically one reading each 1/2" in a line) of the area that encompasses the code required volume. For UT that would include the available scanning surface.

7.1.5 Record radiation field information on the report (this may require assistance from the health physics group).

7.1.6 Sign and date the data sheet then forward it to the NDE Level IlIl.

7.2 Evaluation 7.2.1 The data gathered by the initial examiner SHALL be reviewed by the NDE Level Ill or/ designee to determine if alternate methods may be used to achieve additional coverage.

7.2.2 If alternate methods would provide additional coverage, a review of the benefit versus the required resources (radiation dose, time, cost etc.) to achieve that coverage SHALL be performed by the NDE Level Ill to determine if that action is practical (see Step 7.3).

_ _ _ _ _ _ _ _ _ _ __ __ _ _ __'_ _ __ _ _P a g e 5 of 1 3 7.2.3 If it is determined that the entire examination volume or area cannot be examined due to interference by another component or part geometry, a reduction in examination coverage on any Class 1 or Class 2 weld may be accepted provided the reduction in coverage for that weld is less than 10%.

The applicable examination records SHALL identify both the cause and percentage of reduced examination coverage (see Step 7.4).

7.3 Alternate Methods to Achieve Coverage 7.3.1 For surface examinations, MT and PT may be interchanged / intermixed as appropriate to the material and the conditions.

7.3.2 For volumetric examinations, RT may be substituted for or augment UT assuming the ability to drain the line, and that the wall thickness / diameter is within a practical range.

7.3.3 For UT, use of other angles, full node or node and one half calibrations, skewed scans or approach from another surface to achieve additional coverage SHALL be considered.

7.4 Determining Coverage Achieved When evaluation of initial and alternate examination methods results in examinations, which do not provide full coverage, a determination of percent coverage SHALL be made. The required examination coverage is defined by applicable figures in ASME Sect Xl.

7.4.1 For surface examinations, a worksheet similar to that shown in Figure 4 SHALL be completed.

i For ASME Section Xl appendix Vill exams, code coverage

. ,maybe limited by what the procedure has been demonstrated.

7.4.2 For volumetric examinations, a worksheet similar to that shown in Figure 5 or Figure 6 (ultrasonic examinations) SHALL be completed.

PRAIRIE ISLAND NUCLEAR GENERATING PLANT SECTION WORK INSTRUCTION SWI NDE-LTS-1 REV: 1 Page 6 of 13 7.5 Should the evaluation show that 90% weld coverage has been achieved, attach all related information to the original NDE report and no further action is required.

7.6 Contractor procedures for performing examinations utilizing automated equipment (e.g. reactor vessel and nozzle safe-end exams) SHALL be reviewed by an NDE Level IlIl in the appropriate method to ensure the requirements for identifying, quantifying and recording of limitations encountered are adequately addressed.

7.7 When it has been determined that the maximum examination coverage practically achievable for a code required item is less than required; a relief request is required to be submitted to the NRC (5AWI 14.6.0).

8.0 ACCEPTANCE CRITERIA This item is not applicable to this procedure.

9.0 REPORTING 9.1 Information addressed in Figures 3, 4, 5 and 6 (as applicable) SHALL be reported.

9.2 Information for examinations that are required to meet Reg. Guide 1.150 SHALL also include the following from Appendix A - Alternate Method:

7.c 'The best estimate of the portion of the volume required to be examined by the ASME Code that has not been effectively examined such as volumes of material near each surface because of near-field or other effects, volumes near interfaces between cladding and parent metal, volumes shadowed by laminar material defects, volumes shadowed by part geometry, volumes inaccessible to the transducer, volumes affected by electronic gating, and volumes near the surface opposite the transducer. Sketches and/or descriptions of the tools, fixtures and component geometry which contribute to incomplete coverage should be included."

9.3 Reference System Recording of limitations SHALL be based on the reference system shown in the original examination procedure.

PRAIRIE ISLAND NUCLEAR GENERATING PLANT SECTION WORK INSTRUCTION 9.4 Documentation A picture of the limitation should be taken and added to the description, preferably in a digital format.

10.0 RECORDS 10.1 Inservice inspection examinations SHALL be incorporated in the ISI records. See UISI Examination Program."

10.2 Records of other examinations SHALL be the responsibility of the organization requesting the examination.
