SUBJECT:

REQUEST FOR RELIEF NO. 14, REVISION 1, FOR THE UNIT 1 3RD 10-YEAR INTERVAL INSERVICE INSPECTION PROGRAM (TAC NO.

MB7975)

On August 5, 1994 we submitted for review our third 10-year Inservice Inspection Examination Plan for Unit 1 and, on March 28,1995, a response to a request for additional information to that plan. The Nuclear Regulatory Commission (NRC) issued its evaluation of the third 10-year Interval Program Plan on February 22, 1996.

On March 6, 2003 we submitted Unit 1 Relief Request No. 14, Revision 0, for "limited examinations" associated with that plan. The NRC, by letter dated July 22, 2003, sent a request for additional information (RAI). This letter responds to the RAI by submitting Revision 1 to Unit 1 Relief Request No. 14. The revised relief request addresses the concerns expressed in the RAI. Revision 1 supercedes Revision 0 in its entirety. 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.

This letter contains no new commitments and no revisions to existing commitments.

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

ISI Relief Request No. 14 (Rev. 1), Prairie Island Unit 1, 3rd Interval Limited Examination SYSTEM: Various CLASS: 1 and 2 CATEGORY: Various ITEM NO: Various Impractical Examination Requirements:

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.

I of 16

ISI Relief Request No. 14 (Rev. 1), Prairie Island Unit 1, 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. Inthe 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 I - 2002 Refueling Outage."

Part A: Category B-A, "Pressure Retaining Welds in Reactor Vessel" Reactor Vessel (RV) Weld (W-6), Head to Flange:

The RV head-to-flange weld is subject to volumetric and surface examination. In addition to Section Xl Code requirements the volumetric examination was performed pursuant to the requirements of Regulatory Guide 1.150. The material of the head is A533 Grade B and the flange is A508 Class 1 carbon steel. The weld was examined, to the maximum extent practical, using a 0 degree longitudinal wave and 45 and 60 degree shear waves. Supplemental ultrasonic techniques were considered to extend examination coverage of the weld required volume (WRV). It was determined that no significant additional coverage could be obtained. 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 undue hardship imposed without offering a commensurate increase in safety with cost benefit.

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

2002M027). No relevant indications were detected.

The weld is included in the boundary examined by VT-2 during pressure testing.

The ultrasonic reflectors recorded with this examination are within the outer 75% of through-wall thickness, are not surface related, and are not suspected of being cracks.

The required volumetric examination of the WRV was limited from the flange side of the weld due to weld joint configuration and close proximity of the flange to the intersecting radius of the reactor head. Inaddition, there are three 5.5 inch wide lifting lugs located approximately 120 degrees apart and 3 inches from the toe of the weld on the head that prevent 100% scanning and axial coverage from the head side of the weld, however, coverage of the WRV was approximately 94%. Due to the ramp radius from the flange side of the weld, axial scanning of the WRV was limited to approximately 38.9% using a 45 degree shear wave and 23.6% using a 60 degree shear wave. Circumferential scanning in the clockwise and counterclockwise 2 of 16

ISI Relief Request No. 14 (Rev. 1), Prairie Island Unit 1, 3r Interval direction of the WRV was limited to 50% again by the flange and could only be performed on the head side of the weld.

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 Vill, Supplement 2. The examination was conducted using 45 and 60 degree transducers. The safe-end material is austenitic stainless Type 316 joined to a stainless type 316 45 degree piping elbow. The examination is limited to 50% in the axial and circumferential directions due to the safe-end to elbow weld joint configuration and proximity of the adjacent safe end to nozzle weld, The credited volumetric examination of the WRV was limited to 50% in that 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 Performance Demonstration Initiative (PDI) Appendix Vil 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 undue hardship imposed without offering a 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.

2002P080). No relevant indications were detected.

The weld is included in the boundary examined by VT-2 during pressure testing.

The credited volumetric examination of the WRV was limited to 50% 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 undue hardship imposed without offering a commensurate increase in safety with cost benefit.

The required surface examination was performed using liquid penetrant. 100% of the required surface area was inspected (Inspection Report No. 2002P072). No relevant indications were detected.

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 2002 ISI Outage Summary Report. NMC will continue to document limitations.

13 of 16

ISI Relief Request No. 14 (Rev. 1), Prairie Island Unit 1, 3rd Interval All in-service inspections at Prairie Island Unit 1 have been completed to the greatest extent practical. When limitations to required inspections are encountered, Xcel Energy Metals &

Materials Resources North procedure ISI-LTS-1 was applied. ISI-LTS-1 (Attachment 34) is used when an ASME Section Xl 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.

@& XcelEnergy- November 25.002 Review of Indications Unit 1 2002 RFO Report # -2002U074 Iso # - ISI-49 Component ID - W-6 (Head to Flange) Indication(s) -#1 thru #6 Method - UT 45° and 60° Procedure - ISIAJT-3A Rev. 8 With TCN 02-3 Code - ASME Section Xl 89 with No Addenda NRC Reg. 1.150 Rev. I Discussion These Indications are being reviewed after being identified during the scheduled examination of weld W6 on 1112212002. The Indications have been previously identified during previous examinations and found to be acceptable.

The indications observed on 11122I2t02 are reported as linear with a maximum amplitude of-35%

DAC.

Assumptions Based on nominal waft thickness and curvature correction the Indications are not within the Inner 25%

of the through-wan dimension. (see attached calculations)

Summarv The procedure referenced above Is intended to reflect the requirements of Reg. Guide 1.150 Rev.1.

Appendix A Altemative Method' paragraph 6.2 b.. alltows Reflectors which are at metal paths representing 25% and greater of the through-wall measured from the Inner surface should be recorded In accordance with the requirements of ASME Section Xl and characterized at 50% DAC. The reflectors in question are within the outer 75% of through-wall thickness, are sub- surface and are not suspected of being cracks. The amplitude of the subject refledors does not exceed 50% of DAC and therefore do not require characterization/comparlson to the code for an acceptancehrejection determination.

The Indications noted on report 2002UO74 are acceptable and require no further evaluation.

Pt-I Indication Review Rpt # 0094 ISO# IS149 Item # - W-6 (360 deg) Indication # - 1 through 5 L New Iso #-same New Item #-same Method - UT 00 Procedure - NSP-UT-3A Rev 5 wi FC 96-PIUi-1 Code - ASME Sect Xl '89 with No Addenda NRC Reg Guide 1.150 Rev I Discussion -

These indications are being evaluated as a result of an informational examination done during the Winter '96 outage. The reason for performing this examination was to clear up concerns about previous exams as to reference location for 0 deg and to obtain baseline automated examination data.

The indications were reported as "Linear, and the largest one measured 0.55' X 0.4" with a maximum amplitude of 29% DAC. Based on nominal wall thickness, the z indications are not within the inner 25% of the through-wall dimension. (see calculations below). The indication data with this report indicates that there was no complete loss of back associated with these indications that the recording of these indications was a result of amplitude in regard to DAC. In addition there were no indications that were greater than or equal to the remaining back reflection. Previous evaluations related to the examinations in this and the adjacent areas were performed in conjunction with report #940203 and the results were found to be acceptable.

Assumptions -

- There is no change in metal path associated with these indications, they are laminar in nature.

- Based on nominal wall thickness, the indications are not within the inner 25% of the through-wall dimension.

Code requirements -

The procedure noted above provided the examiner with criterion for evaluating and recording indications under circumstances determined from the following source documents; ASME Sect Xl IWA-2232 refers to Appendix I which refers to Sect V Art 4 with supplements (the supplements do not affect this evaluation). For laminar reflectors, T-441.3.2.9 (a) requires recording of "... all areas giving indications equal to or greater than the remaining back reflection' for determining interference with angle beam examinations. T-441.3.2.9 (b) requires recording of '... all areas where one or more discontinuities produce a continuous total loss of back reflection accompanied by continuous indications in the same plane' for acceptance. For planar reflectors found by straight beam, T-441.3.2.10 requires recording of" all reflectors that produce a response equal to or greater than 50% of the distance-amplitude correction (DAC).

The Reg Guide requirement for Indications without Changing Metal Path' (from I of 2 Flew _6-____Y_ _I

P1-1 Indication Review Appendix A) is to record when any continuous dimension exceeds one inch for the outer 75% of the through-wall dimension and, if the indication falls within the inner 25%

of the through-wall dimensions, recording should be at 20% DAC and evaluation peWformed at 50% DAC.

tJ)

Summary -

The indications noted on report #96-0094 do not fall under these criterion and do not require further evaluation.

Calculations -

Determination of % through wall (depth from OD surface)

Ind #1 - 2.70' MP / 5.512' T = 0.4898 or 48.98%

Ind #2 - 2.49' MP 15.512' T = 0.4517 or 45.17%

Ind #3 - 2.49* MP /5.512' T = 0.4517 or 45.17%

Ind #4 - 3.01" MP /5.512' T = 0.5461 or 54.61%

Ind #5 - 2.88" MP 15.512" T = 0.5225 or 52.25%

MP stands for Metal Path taken from page I of the UT report.

The 5.512" T is the thickness of the component taken from the value on the UT report.

These indications are being evaluated as a result of an informational examination done during the Winter '96 outage. The reason for performing this examination was to clear up concerns about previous exams as to reference location for 0 deg and to obtain baseline automated examination data.

The indications were reported as linearn with a maximum amplitude of 40% DAC.

Previous evaluations related to the examinations in this and the adjacent areas were performed in conjunction with reports #94-0240 and 90-323, and the results were found to be acceptable.

Assumptions -

- Based on nominal wall thickness, the indications are not within the inner 25% of the through-wall dimension. (see calculations below)

Summary -

The procedure referenced above is intended to reflect the requirements of Reg. Guide 1.150 Rev 1. Appendix A "Alternative Method' paragraph 6.2 b., allows that Reflectors which are at metal paths representing 25 percent and greater of the through-wall measured from the inner surface should be recorded in accordance with the requirements of ASME Section Xl and characterized at 50 percent DAC.' The reflectors in question are within the outer 75 percent of the through-wall thickness, are not surface related and are not suspected of being cracks. The amplitude of the subject reflectors does not exceed 50 percent DAC and do not require characterization/comparison to the code for an acceptance/rejection determination.

The indications noted on report #96-0095 are acceptable and require no further evaluation.

Pi 1 Indication Review Rpt # 0111 Iso # -iSI49 Item # - W-6 Indication # - 1 through 8 Nw so #-same New Item # - same Method -UT 60 Procedure - NSP-UT-3A Rev 55 w I FC 96-PIUI-1 Q Code - ASME Sect Xl '89 with No Addenda NRC Reg Guide 1.150 Rev 1 Discussion--

These indications are being evaluated as a result of an informational examination done during the Winter '96 outage. The reason for performing this examination was to clear up concerns about previous exams as to reference location for 0 deg and to obtain i baseline automated examination data.

The indications were reported as 0LinearX with a maximum amplitude of 40% DAC.

Previous evaluations related to the examinations in this and the adjacent areas were Z performed in conjunction with reports #94-0241 and 90-324, and the results were found to be acceptable.

Assumptions -

- Based on nominal wall thickness, the indications are not within the inner 25% of the through-wall dimension. (see calculations below)

Summary -

The procedure referenced above is intended to reflect the requirements of Reg. Guide 1.150 Rev 1. Appendix A "Altemative Method' paragraph 6.2 b., allows that "Reflectors which are at metal paths representing 25 percent and greater of the through-wall measured from the inner surface should be recorded in accordance with the requirements of ASME Section Xl and characterized at 50 percent DAC.' The reflectors in question are within the outer 75 percent of the through-wall thickness, are not surface related and are not suspected of being cracks. The amplitudes of the subject reflectors do not exceed 50 percent DAC and do not require characterization/

comparison to the code for an acceptancelrejection determination.

The indications noted on report #96-0111 are acceptable and require no further evaluation.

Pi 1 Indication Review Calculations - From calibration report WDC-003 the 114 T hole is at 2.0 screen divisions and 2.65 metal path with a measured angle of 60 deg in the cal block.

Ind #1 - cos 60 deg = 0.5 0.5

3.5!MP = 1.75" depth from outer surface 1.75' / 5.512' = 0.3175 or 31.75% throuah-wall Ind #2 - cos 60 deg = 0.5 0.5

3.5MP = 1.75" depth from outer surface 1.75' / 5.512' = 0.3175 or 31.75% through-wall Ind #3 - cos 60 deg = 0.5 0.5

3.57'MP = 1.785" depth from outer surface 1.785" 5.5120 = 0.3238 or 32.38% through-wall Ind #4 - cos 60 deg = 0.5 0.5

3.52'MP = 1.76" depth from outer surface 1.76' / 5.512N = 0.3193 or 31.93% throunh-wall Ind #5 - cos 60 deg = 0.5 0.5

3.52'MP = 1.76" depth from outer surface 1.76 / 5.512' = 0.3193 or 31.93% through-wall Ind #6 - cos 60 deg = 0.5 0.5 ' 3.65'MP = 1.825" depth from outer surface 1.825' / 5.512' = 0.3311 or 33.11% through-wall Ind #7 - cos 60 deg = 0.5 0.5

3.71'MP = 1.855" depth from outer surface 1.855' / 5.512 = 0.3365 or 33.65% through-wall Ind #8 - cos 60 deg = 0.5 0.5 ' 3.53'MP = 1.765" depth from outer surface 1.765 /5.512' = 0.3202 or 32.02% through-wall MP refers to metal path taken from pg 1 of the UT report.

The 5.512N T is the thickness of the component taken from the value on the UT report.

XCEL ENERGY METALS & MATERIALS RESOURCES NORTH INSERVICE INSPECTION - NONDESTRUCTIVE EXAMINATION PROCEDURE l 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 DEFINIONS 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 - T 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.

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 l 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).

For volumetric examinations, RT may be substituted for or augment UT assuming the ability to drain the line, and that the wall thickness I 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 I 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 E applicable figures in ASME Sect Xl.

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 Ill 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.
