• Welch MN 55089 November 16, 2002 10 CFR Part 50 Section 50.55a U S Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555 PRAIRIE ISLAND NUCLEAR GENERATING PLANT Docket No. 50-306 License No. DPR-60 Request for Relief No. 9 for the Unit 2 Third 10-year Interval Inservice Inspection Program On November 15, 1994 we submitted for review our third 10-year Inservice Inspection Examination Plan for Unit 2 and, on April 19, 1995, relief request revisions associated with that plan. The NRC issued its evaluation of the Third 10-year Interval Program Plan on February 22, 1996.

The purpose of this letter is to submit a relief request for "limited examinations" associated with that plan. Attached is Unit 2 Relief Request No. 9, Revision 0 which addresses those limited examinations. We are requesting relief pursuant to 10 CFR Part 50, Section 50.55a(g)(5)(iii) due to the impracticality of obtaining "100%" examination coverage for the affected items.

By letter dated March 21, 1997, we committed to submitting relief requests for "limited" examinations following each refueling outage inspection (whereas the regulation only requires that the relief requests be submitted within 12 months following the end of the inspection interval). We recently identified that we missed one, for the limited examinations encountered in the Spring 2000 Unit 2 refueling outage. Our review has determined that we submitted the requests following each of the other refueling outages since 1997. The attached relief request is for that Spring 2000 outage. We apologize for any inconvenience our failure to previously submit that relief request may have caused.

USNRC NUCLEAR MANAGEMENT COMPANY, LLC November 16, 2002 Page 2 In this letter we have made no new Nuclear Regulatory Commission commitments.

Please contact Jack Leveille (651-388-1121, Ext. 4142) if you have any questions related to this letter.

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION PRAIRIE ISLAND UNIT 2,3RD INTERVAL EXAMINATION PLAN ISI Relief Request No. 9 (Rev. 0)

Limited Examination SYSTEM: Various Class: 1 and 2 Category: Various Item: Various Impractical Examination Requirements:

ASME Section Xl (1989 no addenda) Code requires full examination of inservice inspection (ISI) components per Table IWB-2500-1, and IWC-2500-1. Reg. Guide 1.147, Rev. 12 endorses Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds." This Code Case allows greater than 90% examination coverage of a weld to meet the "essentially 100%" requirement.

NRC Information Notice 98-42 "Implementation of 10 CFR 50.55a(g) Inservice Inspection requirements" 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 XI.

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% coverage is not achievable on some ISl components required to be examined for the Third Ten Year Interval.

Basis for Relief:

The following 10 CFR 50.55a paragraphs apply to the inservice inspection of components in accordance with the ASME Section XI code:

50.55a(g)(1): For a boiling or pressurized water-cooled nuclear power facility whose construction permit was issued prior to January 1, 1971, components (including supports) must meet the requirements of paragraphs (g) (4) and (5) of this section to the extent practical.

50.55a(g)(4): 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 pre-service 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.

50.55a(g)(5)(iv): 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 ...

Page 1 of 6

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION PRAIRIE ISLAND UNIT 2,3RD INTERVAL EXAMINATION PLAN Prairie Island was designed and most components constructed and installed prior to development of ASME XI, 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 obstructions, interferences, and weld joint configurations.

A summary of the limited examinations are described below and included in Table RR 9.

Part A: Category B-B, "Pressure retaining Welds in Vessels other than Reactor Vessels."

Chemical and Volume Control (VC) Weld (W-2), Cap-Integral Tube-sheet:

Volumetric coverage limited, due to cap to tube-sheet configuration, to 48.75%

for UT examination. See Attachment 1, ISI drawing 2-1SI-34 and Attachment 7, Examination Report Number 2000U138.

Part B: Category B-F, "Pressure retaining dissimilar Metal Welds in Vessels Nozzles."

Reactor Coolant (RC) Weld (W-1) Nozzle to Safe-End: Volumetric coverage limited, due to nozzle-to-safe-end configuration, to 62.5% for UT examination.

See Attachment 2, ISO drawing 2-ISI-30A and Attachment 8, Examination Report Number 2000U1 19.

Part C: Category B-J, "Pressure Retaining Welds in Piping" Reactor Coolant (RC) Weld (W-1 3) Nozzle to Pipe: Volumetric coverage limited, due to nozzle to pipe configuration, to 53.75%. See Attachment 3, ISO drawing 2-ISI-5 and Attachment 9, Examination Report Number 2000U125.

Part D: Category C-A, "Pressure retaining Welds in Pressure Vessels" Steam Generator #21 (SG) Weld (W-E) Shell to transition Cone: Volumetric coverage limited, due to ring support at weld junction, to 11.4%. See Attachment 4, ISO drawing 2-ISI-37A and Attachment 10, Examination Report Number 2000U131.

Part E: Category C-C "Integral attachments for Vessels, Piping, Pumps and Valves" Safety Injection Pump 22 Supports A (H-I), B (H-2), C (H-3), D (H-4): Surface examination (MT) coverage limited to 83.0% due to inaccessibility of the bottom Page 2 of 6

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION PRAIRIE ISLAND UNIT 2, 3RD INTERVAL EXAMINATION PLAN of support because of concrete pad interference. See Attachment 5, ISO drawing 2-ISI-60B and Attachments 11 - 14 (Examination Report Numbers 2000M087, 2000M088, 2000M086 and 2000M089).

Residual Heat Exchanger 21, Support A (H-I), and Support B (H-2): Surface examination (PT) coverage limited to 85.2% due to the configuration of the support and concrete pedestal. See Attachment 6, ISO drawing 2-ISI-69A and Attachments 15 & 16 (Exam Report Numbers 2000P054 & 2000P056).

Additional Means of Establishinq Pressure Boundary Inteqrity:

System pressure tests and associated visual inspections (VT-2) required by Section XI are performed at the required frequency to ensure the piping system is capable of maintaining pressure boundary integrity. The B-B category weld was visually examined during a pressure test in 1997, Attachment 26, List of Section XI VT-2 Examinations.

The other pressure retaining welds with limited exams were visually examined during pressure tests in 2000, Attachment 27, List of Section XI VT-2 Examinations.

System integrity is monitored during normal plant 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.

In addition to the UT volumetric examination with limitations for the listed B-F Category weld, the required surface examination (PT) was completed, Attachment 17, Examination Report Number 2000P023.

In addition to the UT volumetric examination with limitations for the listed B-J Category weld, the required surface examination (PT) was completed, Attachment 18, Examination Report Number 2000P037.

In addition to the surface examinations (MT or PT) with limitations of all listed C-C Category integrally attached welds, VT-3 visual examinations were performed, Attachments 19 - 24 (Examination Report Numbers 2000V393, 2000V394, 2000V388, 2000V389, 2000V314, and 2000V313).

Alternate Examination:

Limitations to the required examination coverage have been noted on the applicable ISI examination reports and included in the 2000 ISI Outage Summary Report. NMC will continue to document examination limitations.

Page 3 of 6

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION PRAIRIE ISLAND UNIT 2, 3RD INTERVAL EXAMINATION PLAN In-service inspections at Prairie Island Unit 2 have been performed to the maximum extent practical. When examination limitations are encountered, M&MR procedure ISI LTS-1, "Limitations to NDE," is applied. ISI-LTS-1 (Attachment 25) is used when an ASME Section XI Code required examination results in less than 90% coverage of the required examination volume or area. It requires a review of the procedures to obtain maximum coverage and documentation of the limitation. The procedure also considers whether an alternative method could be used to obtain improved examination coverage required by the Code. This procedure was used for all the items identified above to determine that the maximum examination coverage was achieved.

Limitations to inspections are primarily due to obstructions, interferences, and weld joint configurations. NMC will continue to utilize the most current examination techniques available for future examinations.

XCEL ENERGY METALS & MATERIALS RESOURCES NORTH INSERVICE INSPECTION - NONDESTRUCTIVE EXAMINATION PROCEDURE TITLE: Limitations to NDE NUMBER: ISI-LTS-1 Revision 2 3.0 APPLICABILITY 3.1 This procedure is applicable to examinations performed at Xcel Energy's Nuclear Generating Plants.

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.

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 5.1 Personnel Requirements

• Examination personnel certification and eye examinations shall be documented in accordance with ISI-NDE-0.

• Nondestructive examination personnel shall be certified to a minimum of Level I in the appropriate method to operate equipment and Level IIto interpret test results.

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

• Complete original examination on accessible portions

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

• 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.

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

Sign and date the data sheet then forward it to the Xcel Energy's Field Supervisor.

7.2 Evaluation

• The data gathered by the initial examiner shall be reviewed by the Xcel Energy's field supervisor / designee to determine if altemate methods may be used to achieve additional coverage.

• If altemate 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 Xcel Energy's field supervisor to determine if that action is practical (see para 7.3).

Ifit 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 para 7.4).

XCEL ENERGY METALS & MATERIALS RESOURCES NORTH INSERVICE INSPECTION - NONDESTRUCTIVE EXAMINATION PROCEDURE TITLE: Limitations to NDE NUMBER: ISI-LTS-1 Revision 2 7.3 Alternate methods to achieve coverage

"* For surface examinations, MT and PT may be interchanged / intermixed as appropriate to the material and the conditions.

"* 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.

"* 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 altemate 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 XI.

"* For surface examinations, a worksheet similar to that shown in Fig 4 shall be completed.

"* For volumetric examinations, a worksheet similar to that shown in Fig 5 or 6 (ultrasonic examinations) shall be completed.

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 Xcel Energy's level III 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 (refer to ISIA 1.4).

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

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.

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 Metals and Materials Resurces North Procedure 2.3 "iSI Examination Program".

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