TECHNICAL LETTER REPORT REQUESTS FOR ADDITIONAL INFORMATION ON THIRD 10-YEAR IN-SERVICE INSPECTION INTERVAL REQUEST FOR RELIEF FOR NUCLEAR MANAGEMENT COMPANY PRAIRIE ISLAND NUCLEAR GENERATING PLANT, UNIT 1 DOCKET NUMBER: 50-282

1.

SCOPE By letter dated May 29, 2001, the licensee, Nuclear Management Company (NMC), submitted multiple requests for relief from the requirements of the ASME Code, Section XI, for the Prairie Island Nuclear Generating Plant, Unit 1. These relief requests are for the third 10-year inservice inspection (ISI) interval. Brookhaven National Laboratory (BNL) reviewed the information submitted by the licensee and based on this review, the following information for each relief request is required to complete this evaluation.

2.

REOUESTS FOR ADDITIONAL INFORMATION General (1) Please provide the date when the Third 10-year ISI Interval began for the Prairie Island Nuclear Generating Plant, Unit 1. Response: The 3 rd 10 year Interval began on Dec 17, 1993 and ends Dec. 16, 2003. (2) For the proposed alternative examination, it was stated in the licensee's submittal that Metal and Material Resources Procedure ISI-LTS-1 is applied when limitation to required inspections are encountered. In order to evaluate the acceptability and appropriateness of the proposed alternative, a review of this procedure is required. Please describe the related activities that are applicable to this relief request for all Parts A-E below. Explain how these activities provided an alternative to the Code-required examination(s) and how the licensee gained the maximum obtainable inspection coverage practically possible. Response: ISI-L TS-1 (Attachment 18) is the procedure used when an ASME Section XI Code required examination results in less than 90% Coverage. It requires a review ofprocedures 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. (3) None of the limitations identified in Table 1 of the submittal discussed the ALARA concerns. However, the alternative examination section of the submittal states that "Limitations are due to design, geometry, and materials of construction of the components or ALARA concerns." Explain how the ALARA concerns affected the impracticality in performing the Code-required inspection activities for the subject welds.

Response: Some of the examinations are in significant radiation fields, and excessive efforts to use alternative examination techniques without significant gain in examination coverage are not warranted. These radiation fields are recorded on the limitation datasheets provided with the relief requests as attachments. For this relief request no specific item was identified as an ALARA concern in itself Configuration issues are the main reason for the relief request or new Performance Demonstrated Initiative UT Methods as allowed by 10 CFR55a limit the acceptable examination coverage. 2.1 Req uest for Relief No.11. for "limited examinations" associated with Third 1 0-year Interval Program Plan Issued on February 22, 1996. Part A: Pressure retaining welds in the reactor coolant system piping, Weld W-6 (pipe to elbow) and Weld W-1 (RC pump to pipe), Examination Category B-J, Item No. B9.1 1. Pursuant to 10 CFR 50.5 5a(g)(5)(iii), the licensee requested relief from the 100% volumetric examination requirements for a reactor coolant system pipe to elbow weld W-6 and a reactor coolant pump to pipe weld W-1. Due to interferences and access limitations, the licensee performed single side examination only and therefore, could examine 75% (for the weld W-6) and 38.85% (for the weld W-1) of the Code-required volumes. In order for the proposed alternative to be considered, please provide the following: (1) Table 1 of the licensee submittal indicates that the limitation for the weld W-6 is (PDI) single sided examination due to pipe configuration and for the weld W-I is (PDD) single sided examination due to pump to pipe configuration. The sketches provided in the associated summary sheets are not clear to understand these limitations. Explain with sketches or photos what kind of configuration problems are associated with each of these welds. Discuss the relationship of the configuration limitations with PDI and provide the reference of the PDI section. Response: No photos of these limitations are available. The limitations for W-1 and W-6 are related to contour configuration of the OD scan surfaces that precluded a four directional scan of the weld volume particularly from the valve side (W-1) or pump side (W-6) of the weld, which is shown on the sketches previously submitted and new sketches (Attachments 1 and 2). 10 CFR 50.55a(b)(2)(xv)(A), 10 CFR 50.55a(b)(2)(xv)G and 10 CFR 50.55a(b)(2)9(xvi), define new requirements for coverage and qualification demonstration of UT Methods. These requirements affect both piping and RPV examinations. The PDI UT methodology is in agreement with the Federal Code regarding single side access for piping. The Federal Code requires that if access is available the weld shall be scanned in each of the four directions (parallel and perpendicular to the weld) where required. Coverage credit may be taken for single side exams on ferritic piping. However, for austenitic piping a 2

procedure must be qualified with flaws on the inaccessible side of the weld. The final rule requires that single side access examinations must demonstrate "equivalency to two sided examinations". Current technology is not capable of reliably detecting or sizing flaw on the inaccessible side of an austenitic weld, for configurations common to US nuclear applications. Instead of a full single side qualification, PDI offers a best effort approach, which demonstrates that the best available technology is applied. This best effort approach does not meet the requirements of the Federal Code. PDI lists the limitation that single side examination is performed on a best effort basis. This requires the inaccessible side of the weld to be listed as an area of limited coverage. Hence for W-1 and W-6 only limited coverage is obtained. Table 1 has been corrected to show W-1 limitation to be 50%and W-6 limitation to be 50%. See Attachments I and 2, UT examination reports and sketches (2001 U039 and 2001U004). (2) The description in the Table 1 of the licensee submittal identifies the weld W-6 is a circumferential weld between the RC piping to elbow, while the sketch in the corresponding summary report No. 300130 indicates that the weld is for the piping to valve. Clarify this discrepancy. Response: The Table I entry is incorrect and should say "Piping to Valve" as indicated on inspection report and sketch (Attachment 2). The limitation coverage for W-1 is also incorrect and should be 50% Coverage. These have been entered into the plant corrective action process. (3) Confirm that Code-required essentially 100% surface examination was performed for both W-6 and W-1 welds. Response: 100% coverage PT surface examination was performed on these welds. (4) Provide details of the alternatives, including system pressure test requirements for the reactor coolant system, proposed and/or attempted by the licensee for the subject welds. Response: VT-2 (visual examinations) and functional pressure test requirements are being performed and meet the code requirements for these welds. As noted above, a 100% OD PT surface examination was also performed on these welds. Part B: Pressure retaining welds in pressure vessels, Weld W-E (#12 steam generator shell to transition) and Weld W-2 (#12 RHR Rx shell to flange), Examination Category C-A, Item No. C1.10. Pursuant to 10 CFR 50.55a(g)(5)(iii), the licensee requested relief from the 100% volumetric examination requirements for a shell-to-transition weld W-E on the #12 Steam Generator and a shell-to-flange weld W-2 on the #12 RHR Heat Exchanger. Due to interferences, the licensee is proposing a 70.88% (for the weld W-E) and 27.26% (for the weld W-2) of the Code-required volumes. In order for the proposed alternative to be considered, please provide the following: 3

(1) The submittal is requesting relief from the Code-required volumetric examination for the welds W E and W-2 based on limitations in scanning the welds due to interferences caused by the weld geometry and configuration. Explain if the alternatives include surface examinations, radiography, and/or any other examination methods and describe the results of these examinations. Response: The alternative does not include surface examination since the code requirement is full weld volumetric. Also, radiography is not a viable option for these volumetric examinations since the S/G and heat exchanger would have to be drained down and SIG internals would have to be removed to perform radiography. No alternative examinations were performed. (2) The sketches given in Summary Nos. 301070 and 303054 are not clear. Provide sketches showing the Code-required volume to be examined and the scanner locations with volume coverage as practical. Response: Attached are UT reports 2001 U01 0, 2001 U029 and associated sketches (Attachments 3 and 4) and ISI-93B diagram of W-2 (Attachment 5). The UT coverage indicated on Table 1, of 70.88% for Weld W-E is incorrect and should state 77.54% coverage. This has been entered into the plant corrective action process. Weld W-E downstream UT scan is inaccessible due to restraining ring around Steam Generator. For W-2 flange, contour surface prevents adequate scan coverage downstream. (3) Provide details of the alternatives, including system pressure test requirements for the components containing the welds, proposed and/or attempted by the licensee for the subject welds. Response: VT-2 (visual examinations) and functional pressure test requirements are being performed and meet the code requirements for these welds. Part C: Integral attachment welds for piping and pumps, Examination Category C-C, Item Nos. C3.20 & C3.30. Pursuant to 10 CFR 50.5 5a(g)(5)(iii), the licensee requested relief from the Code-required surface examinations for nineteen integral attachment welds for piping and pumps in the main steam piping, feedwater piping, SI pumps, and RHR heat exchanger. For six of these welds, no surface examination could be performed due to interferences. In order for the proposed alternative to be considered, please provide the following: (1) For these welds, were any alternative inspection measures considered, such as examining surrogate welds, or performing a visual inspection to look for signs for degradation near the weld ? Response: This ASME Code Category requires all integral attached welds to be inspected each interval. So there are no surrogate welds. The Code required examination is a surface examination, PT or MT. A Visual VT-3 examination is 4

performed on these supports and the weld areas that are accessible as required by IWF and Code Case 491. No degradation near the welds was observed. These welds are covered by VT-2 (visual examinations) and functional pressure tests. (2) The diagrams given in the Limitation Record sheets are not clear, specifically the surface areas to be examined and the inaccessible portions of the weld. Some are covered by guard pipes and the licensee submittal for these welds include only the Magnetic Particle Examination sheets and no sketches or diagrams. Please provide detail sketches or photos with sufficient details so that the staff could determine the interferences on accessing the Code-required surfaces for the subject welds. Response: Guard piping completely encloses the weld areas. See attached Isometric drawing ISI-51B, ISI-68-A, and ISI-69 (Attachments 6, 7, and 8) for location of Guard Pipe. Photograph of guard pipe not available. (3) Explain why the integral attachment for the #12 RHR Heat Exchanger Support integral attachment weld is considered under Examination Category C-C, Item Number C3.20 which is applicable to piping. Response: This item number should be C3.10. This has been entered into the plant corrective action process. (4) Explain the following specific welds: (a) Summary No. 301589 shows a weld to pipe obstructed by guard pipe and insulation. Why can the insulation not be removed for surface examination? Response: Removal of insulation would not facilitate inspection. The inspection is constrained by guard pipe and configuration of the restraint collar. (b) Summary No. 301258 shows floor penetration which prohibits examination of the middle 12" of the two vertical welds on the pipe collar. The drawings do not clearly demonstrate the subject welds (2 circumferential welds and 2 vertical welds) and inaccessible portions of these welds. Please provide new sketches or photos showing the welds with inaccessible portions. Response: There is no photo available. A new sketch is provided and examination -report 2001M034 (Attachments 9 and 11). (c) Sketches in summary nos. 302082, 302086, and 303052 are not very clear. Please provide sketches with explanations how the Code-required surface areas in these welds are not accessible for examination. Response: Rough weld area prohibits PT examination. See attached reports 2001M030, 2001M034 and 2001P056 and attached Isometric Drawing ISI-83C (Attachments 9, 10, 11, 12, and 13). For 2001M030, there is less than 2" gap between 5

pump and integral attachment weld pedestal, For 2001M034, Attachment 9 shows how the floor interferes with the inspection. Report for 2001P056 is included again, note the description of limitations on page 2. Part D: Pressure retaining welds in austenitic stainless steel or high alloy piping, Examination Category C-F-i, Item Nos. C5.11 & C5.21. Pursuant to 10 CFR 50.55a(g)(5)(iii), the licensee requested relief from Code-required surface and volumetric examinations for the pressure retaining welds in RHR Pump B discharge lines and SI test return line. In order for the proposed alternative to be considered, please provide the following: (1) For these welds, were any alternative inspection measures considered, such as examining surrogate welds, or performing a visual inspection to look for discoloration where the pipe is exposed or discoloration of the insulation near the weld, which could be indicative of degradation of the weld? If so, please provide the details of these inspections. Response: There are 377 C-F-1 welds in PI Unit 1 plant, 51 welds are examined during the 3"d Interval. The code requires 29 minimum welds or a total of 7.5 % of 3 77, P1 Unit I inspects 51 C-F-1 welds (the last 12 to be completed in the Fall 2002 outage). A VT-2 (visual examinations) is conducted during required functional pressure examinations. No indications have been observed from these inspections. (2) Please provide sketches or photos with sufficient details so that the staff could determine the interferences on accessing the Code-required surfaces and volumes for the subject welds. Response: See attached Sketches and inspection reports 2001 U013 (Attachment 14), 2001U034 (Attachment 15), and sketch for 2001U040 and 2001P070 (Attachment 16). (3) Table 1 of the licensee submittal indicates that the limitation for the weld W-18 is (PDI) single sided examination due to tee to valve configuration and for the weld W-1 is (PDI) single sided examination due to weld crown configuration. Explain with sketches or photos what kind of configuration problems are associated with each of these welds. Discuss the relationship of the configuration limitations with PDI and provide the reference of the PDI section. Response: See attached sketches and reports 2001 U013 (Attachment 14) and 2001U034 (Attachment 15). 10 CFR 50.55a(b)(2)(xv)(A), 10 CFR 50.55a(b)(2)(xv)G and 10 CFR 50.55a(b)(2)9(xvi), define new requirements for coverage and qualification demonstrations of UT Methods. These requirements affect both piping and RPV 6

examinations. The PDI UT methodology is in agreement with the Federal Code regarding single side access for piping. The Federal Code requires that if access is available the weld shall be scanned in each of the four directions (parallel and perpendicular to the weld) where required. 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 inaccessible side of the weld. The federal code requires that single side access examinations must demonstrate "equivalency to two sided examinations". Current technology is not capable of reliably detecting or sizing flaw on the inaccessible side of an austenitic weld, for configurations common to US Nuclear applications. Instead of a full single side qualification, PDI offers a best effort approach, which demonstrates that the best available technology is applied. This best effort approach does not meet the requirements of the Federal Code. PDI lists the limitation that single side examination is performed on a best effort basis. This requires the inaccessible side of the weld to be listed as an area of limited coverage. Hence for W-8 and W-1 austenitic welds the examination technique is only capable of a maximum coverage of 50%. The coverage limitation on these welds is further limited by OD contour configuration surface due to Tee to Valve (W-18), 49.2% and Weldolet to Pipe (W-1) geometry 39.18%. (4) The RHR pump "B" discharge pipe to penetration weld is claimed to be inaccessible due to penetration sleeve and welded restraint. Explain if the licensee has considered other alternatives, including radiography, visual examination. Provide details of the system pressure test requirements applicable to the components containing the subject welds. Response: VT-2 (visual examinations) and pressure test requirements are being performed and meet the code requirements for these welds. The RHR pressure test is performed at nominal operating pressure of greater than or equal to 350 psig for at least 10 minutes, the insulation may be in place. Radiography would require draining the system and would be an undue hardship. (5) Confirm that Code-required essentially 100% surface examination was performed for both W-18 and W-1 welds. Response: The surface examinations were performed to essentially 100%. Part E: Pressure retaining weld in carbon or low alloy steel piping, Examination Category C-F-2, Item No. C5.50. Pursuant to 10 CFR 50.55a(g)(5)(iii), the licensee requested relief from the Code-required surface examination for the Tee-Pipe Weld in the Main steam "B" line. In order for the proposed alternative to be considered, please provide the following: (1) Please provide sketches or photos with sufficient details so that the staff could determine 7

the interferences on accessing the Code-required surfaces and volumes for the subject weld. Response: See attached Sketches and report 2001M016 (Attachment 17). (2) Confirm that Code-required essentially 100% volumetric examination was performed for the weld W-9 (LSD2U). Response: Yes, greater than 90% UT coverage was achieved. (3) Provide details of the alternatives, including system pressure test requirements for the main steam line containing the weld, proposed and/or attempted by the licensee for the subject weld. Response: VT2 (visual examinations) and functional required examinations are performed each period. (4) The Examination Category C-F-2 and Item Number C5.50 refers to piping welds 3/8 inch nominal wall thickness for piping > NPS 4 and includes both circumferential weld (Item Number C5.51) and longitudinal weld (Item Number C5.52. Clarify the Code Item Number applicable to the tee-to-pipe weld in the main steam "B" line. Response: The W-9 (LSD2U) is a weld with both long seam and circumferential welds. the designator (LSD2U) indicates this. We use Code Case N-524 and we give this type of weld the ASME item number C5.50, which indicates both weld types. 8

• 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 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. Page 2 of 12

XCEL ENERGY METALS & MATERIALS RESOURCES NORTH INSERVICE INSPECTION - NONDESTRUCTIVE EXAMINATION PROCEDURE TITLE: Limitations to NDE NUMBER: ISI-LTS-1 Revision 2 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; 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 alternate methods may be used to achieve additional coverage. "* 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 Xcel Energy's field supervisor to determine if that action is practical (see para 7.3). " 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 para 7.4). Page 3 of 12

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

0 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.

1. 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 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.

NORTHERN STATES POWER INSERVICE INSPECTION PRAIRIE ISLAND UNIT 1,3RD INTERVAL EXAMINATION PLAN ISI Relief Request No. 11 (Rev. 1) Limited Examination SYSTEM: Various Class: 1 and 2 Category: Various Item: Various Impractical Examination Requirements: ASME Section XI (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 endorses 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. 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 ISI components 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 XI 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 Page 1 of 37

NORTHERN STATES POWER INSERVICE INSPECTION PRAIRIE ISLAND UNIT 1,3RD INTERVAL EXAMINATION PLAN permitted by paragraph (g)(4) of this section, the basis for this determination must be demonstrated to the satisfaction of the Commission Prairie Island was designed and constructed 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 and interference. Summary of the limited examinations are described below and also included in Table 1.
