SUMMARY

PRAIRIE ISLAND NUCLEAR GENERATING PLANT - UNIT 1 September 27, 1983 to September 29, 1983

1.0 INTRODUCTION

~

This report summarizes the inservice inspection examinations per-formed at Prairie Island Nuclear Generating Plant - Unit 1.

This inspection was conducted during the period from September 27 to September 29, 1983 in response to the NRC Staff Evaluation Meeting documented April 18, 1983. Specifically, item 5 of Section 6 states that 10 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 susceptable 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 evcluation of the results from the inservice examinations in-dicated that the integrity of the system has been maintained.

3.0 DISCUSSION OF EXAMINATION 3.1 Inspection Boundary The examination plan focused on piping circumferential butt welds in portions of the Safety Injection system containing stagnant oxygenated borated water. This piping consists of 8" diameter, Schedule 10 (0.148" wall) and 12" diameter, Schedule 10 (0.180" wall) austenitic stairless steel. The components examined and the examination report numbert are summarized in the attached Appendix B - ASME Class 2 Examina-tions, Table S2.2.1.

l LCD101283JJB01 4

3.2 Examination Methods Ultrasonic examination methods and techniques were used to perform the volumetric examinations. The ultrasonic test system consisted of an ultrasonic digital / analog tester and a two-channel strip chart recorder. One channel of the re-corder was calibrated to represent ultrasonic screen height (amplitude) and the second channel was calibrated to indi-cate metal path (range) to the reflector. This approach gives a permanent record of the examinations and allows further evaluation of any indications by the contractor's Level III and Northern States Power Company.

The ultrasonic techniques utilized miniature (1/4" x 1/4"),

5.0 MHz transducers. These were mounted on high tempera-ture 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 exam' nations were aided, when necessary, with i

artificial lighting and verified for adquacy with an 18%

neutral gray card containing a 1/32-inch black line.

3.3 Examination Procedures The ultrasonic examination procedure for pipe welds com-plied with the requirements of Appendix III of ASME Sec-tion XI issued in the Winter 1975 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 Appen-dix E.

3.4 Equipment and Materials All equipment and expendable materials used in the examina-tions are listed either by serial number or type along with their respective calibration date or batch number in Table IV of Appendix E.

The ultrasonic calibration standards used in the examina-tion are listed in Table II of Appendix E.

These standards are owned and maintained by NSP at the plant site.

3.5 Personnel Northern States Power Company contracted Lambert, MacGill, Thomas, Inc. to perform the ultrasonic examinations. Hart-ford Steam Boiler Inspection and Insurance Company, repre-senting ANI, provided the Authorized Inspection.

LCD101283JJB01

All parsonnel involved in the performance or evaluation of examinations are listed along with their title, organization, and ASNT Level of certification in Table I of Appendix E.

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 cali-bration performed on a standard reference before each day's examination, checked before and after each individual examina-tion, and at intervals not exceeding four (4) hours.

In addi-tion, the ultrasonic data wcs recorded on strip charts which were made a part of the inspection report, and permitted fur.

ther evaluation.

3.7 Examination Reports and Documentation All examination reports and documentation are maintained on file by Northern States Power Company. Table I of Appendix B identifies the examination report number (s) for each item examined. Many of the items identify more than one examina-tion report because of the difference types of examinations performed on the item.

Table I of Appendix B 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 ex-amination requirements. For retrieval purposes, the prefix of the inspection report number corresponds with the year that the inspection was performed. The examination report numbers for this outage are prefixed with "83A ".

Table II of Appendix B compares the baseline examination results with the results obtained during this examination.

Table II of Appendix B identifies the isometric drawings that were used for the examinations. The personnel, ul-trasonic calibration blocks, procedures, equipment and materials that were used for the inspection are identified in the tables of Appendix E.

Appendix F contains the Form NIS-1, titled, "0wner's Data Report for Inservice Inspec-tions".
