SUMMARY
PRAIRIE ISLAND NUCLEAR GENERATING PLANT - UNIT 1 SEPTEMBER 19, THRU SEPTEM3ER 22, 1984
1.0 INTRODUCTION
This report sunnarizes the inservice inspection examinations performed at Prairie Island Nuclear Generating Plant - Unit 1. This inspection was conducted during the period from September 19 thru September 22, 1984, in response to the NRC Staff Evaluation Meeting documented April 18, 1983.
Specifically, item 5 of Section 6 s.tates that ten welds will be examined every six months. The examinations were performed with the Unit in operation. Prairie Island - Unit 1 began commercial operation on December 16, 1973.
The examinations were performed on circumferential pipe welds in portions of the Safety Injection system that were identified as containing stagnant oxygenated borated water, and selection was based on those welds that are considered the most susceptible to trans-granular stress corrosion cracking.
Northern States Power Company contracted Lambert, MacGill, Thomas, Inc. to perform the examinations. Hartford Steam Boiler Inspection and Insurance Company, representing ANI, provided the Authorized Inspection.
2.0 INSPECTION
SUMMARY
The results of the nondestructive, (ultrasonic), examinations performed during this inspection revealed no relevant indications which might affect the integrity of the system. However, while performing these examinations UT personnel noted a small build-up of white residue located at 12:00 on the valve side of weld #W-86W. (It should be noted that ultrasonic examinations of pipe-to-valve welds from the cast, stainless steel valve side are impractical and generally not performed.)
The white residue, presumed to be dried boric acid solution, was removed and a very small, (barely discernable), leak was visible. The leak was approximately 1/2 inch from the weld centerline, valve side, with an approximate length of 1/32 inch. This through wall discontinuity was consequently weld repaTred and a visual inspection of the oppposite boric acid supply valve was performed.with no other evidence of leakage being
, observed.
3.0 DISCUSSION OF EXAMINATION 1

q l
i 3.1 Inspection Boundary The examination plan focused on piping circumferential butt welds in l portions of the Safety Injection system containing stagnant oxygenated l borated water. This piping consists of 8" diameter, Schedule 10 (0.148" wall) and 12" diameter, Schedule 10 (0.180" wall) austenitic stainless steel. The components examined and the examination report numbers are sunnarized in the attached Appendix A - ASME Class 2 Examinations, Table S2.2.1. ;
3.2 Examination Methods Ultrasonic examination methods and techniques were used to perforn the volumetric examinations. The ultrasonic test system consisted of an ultrasonic digital / analog tester and a two-channel strip chart re-corder. One channel of the recorder was calibrated to represent ultrasonic screen height brated to indicate (amplitude))and metal path (range to thethe secondThis reflector. channel was cali-approach gives a permanent record of the examinations and allows further evalua-tion of any indications by the contractor's Level III ard Northern States Power Company.
The ultrasonic techniques utilized miniature (1/4" x 1/4"), 5.0 MHz transducers. These were mounted on high temperture wedges which provided refracted shear wave angles of 45 degrees and 52 degrees in the parts to be examined. A 2-1/2 V metal path was used for all examinations.
All visual examinations vere aided, when necessary, with artificial lighting and verified for adequacy with an 18% neutral gray card containing a 1/32" black line.
3.3 Examination Procedures The ultrasonic examination procedure for pipe welds complied with the reouirements of Appendix III of ASME Section XI issued in the Winter 1974 Addenda. All other examination procedures complied with the requirements of the 1974 Edition through and including the Summer 1975 Addenda of ASME Section XI. A listing of the procedures used for the examinations is shown in Table III of Appendix B.
3.4 Equipment and Materials All equipment and expendable materials used in the examinations are listed either by serial number or type along with their respective calibration date or batch number in Table IV of Appendix B.
The ultrasonic calibration standards used in the examinations are listed in Table II of Appendix B. These standards are owned and maintained by Northern States Power Company at the plant site.

3.5 Personnel Northern States Power Company Company contracted Lambert, MacGill, Thomas, Inc. to perform the ultrasonic examinations. Hartford Steam Boiler Inspection and Insurance Company, representir.g ANI, provided the Authorized Inspection.
All personnel involved in the performance or evaluation of examinations are listed along with their title, organization, and ASMT Level of certification in Table I of Appendix B.
Certifications for examination personnel are maintained on file by Northern States Power Company.
3.6 Evaluation Any indications disclosed in the examinations were evaluated by the examiner at that time in accordance with the rules of the procedure and ASME Section XI.
The ultrasonic examiner was aided in his evaluation by a calibration performed on a standard reference before each day's examination, checked before and after each individual examination, and at intervals not exceeding four (4) hours. In addition, the ultrasonic data was recorded on strip charts which were made a part of the inspection report, and permitted further evaluation.
3.7 Examination Reports and Documentation All examinations reports and documentation are maintained on file by Table S2.2.1 of Appendix A identifies Northern Statesreport the examination Power Company number s) for(.each item examined. Many of the items identify more than one examination report because of the different types of examinations performed on the item.
Table 52.2.1 of Appendix A summarizes all the examinations that have been performed to date and identifies the amount that will be examined in the future to complete the ten year examination requirements. For retrieval purposes, the prefix of the inspection report number corre-I sponds with the year that the inspection was performed. The examina-l t
tion report numbers for this outage are prefixed with "84 ".
l Table II of Appendix A compares the baseline examination results with
, the results obtained during this examination. Table III of Appendix A identifies the isometric drawings that were used for the examinations.
The personnel, ultrasonic calibration blocks, procedures, equipment and
' materials that were used for the inspection are identified in the
, tables of Appendix B. Appendix C contains the Form NIS-1, titled.
l "0wner's Data Report for Inservice Inspections".
