)

i This report is a summary of the examinations performed during the lith inservice inspection at the Prairie Island Nuclear Generating Plant - Unit 2. This was the second inspection conducted for inspec-t(on period one of the plant's 2nd ten year interval. The examina-tions were20? performed during the plant's lith refueling outage from October 1986 to November 19, 1986.

Prairie Island - Unit 2 began commercial operation on December 20, 1974.

This report identifies the components examined, the examination

. methods used, the examination number; and, summerizes the examina-tfon results of each of the following areas:

1. Pressure retaining components and supports of the reactor coolant and associated systems classif t' d as ASME Class I and ASME Class 2.

e

2. FSAR Augmented Examinations.

3. Eddy current examination of the Steam Generator. Tubing.

2.0 SUMMARf 0F RESULTS The evaluation of all the results from the inservice examinations indicated that the integrity of these systems has been maintained.

To assure continued integrity of the steam generators (S.G.),

a to-tal of 4 tubes in S.G. 21 and 20 tubes in S.G.

22 were mechanically plugged.

3.0 ASME CLASS 1 AND 2 COMP 0NENTS 3.1 EXAMINATION PLAN The examination plan focused on the pressure retaining compo-nents and their supports of the reactor coolant and associated auxiliary systems classified as ASME Class I and ASME Class 2.

The examination plan was based on the examination requirements of. the ASME Boiler and Pressure Vessel Code Section XI, 1980 Edition through and including the Winter 1981 Addenda, and complied with Prairie Island's Technical Specification, Sec-tion TS 4.15.

The examination is in accordance with the pro-gram' submitted to the United States Nuclear Regulatory Commis-6 sion on March 27, 1981 titled, "ASME Code Section XI Inservice Inspection and Testing Program and Information Required for s

NRC Review of Requests for Relief From ASME Code Section XI Requirements".

1 3.2 EXAMINATION METHODS Ultrasonic examination methods and techniques were used to perform the volumetric examinations. The ultrasonic test sys-tems consisted of an ultrasonic digital / analog tester and a two channel strip chart recorder. One channel of the recorder was calibrated to reflect ultrasonic screen height (amplitude) and the second channel was calibrated to indicate metal path (range) to the reflector.

This approach to the examination gives a permanent record to the extent possible.

Liquid penetrant or magnetic particle examination methods were used to perform the surface examinations.

The liquid pen-etrant examinations were performed using color contrast-solvent removable materials. Magnetic particle ex-aminations were performed using either a yoke with dry powder or an AC L-10 coil with fluorescent prepared bath.

All visual examinations were aided, when necessary, with arti-ficial lighting and verified for adequacy with an 18% neutral gray card with a 1/32 inch black line.

3.3 EXAMINATION PROCEDURES The ultrasonic examination procedures for piping welds com-plied with the requirements of Appendix III of ASME Section XI that was issued in the Winter 1981 Addenda.

All other proce-dures complied with the requirements of the 1980 Edition through and including the Winter 1981 Addenda of ASME Section XI.

A listing of the procedures used for the examinations is shown in Table III of Appendix E.

3.4 E0VIPMENT 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 examinations 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 balance of plant exami~ nations.

Hart-ford Steam Boiler Inspection and Insurance Company, represent-ing ANII, provided the Authorized Inspection.

$E All personnel involved in the performance or evaluation of ex-o aminations are listed along with their title, organization and

1 3.6 EVALUATION Any indications disclosed in the examinations were evaluated by the examiner at the time, in accordance with the rules of the procedure and ASME Section XI.

The ultrasonic examiner (s) was aided in their 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 examination reports and documentation are maintained on file by Northern States Power Company.

Table I of Appendices A,

8, C and D identifies the examination report number (s) for each item examined.

Many of the items identify more than one examination report because of the different types of examina-tions performed on the item.

Table I of Appendix A, B, C and D summarizes all the examina-tions performed to date and identifies the amount that will be l

examined in the future to complete the ten year examination requirements.

For retrieval purposes, the prefix of the in-spection report number corresponds with the year the inspec-l tion was performed.

The examination report numbers for this outage are prefixed with "86 ".

Table II of Appendix A,

B, C and D compares the baseline ex-l amination or previous results with the results obtained during l

this examination. Table III of Appendix A, B, C and D identi-fies the isometric drawings that were used for the examina-l tions.

The personnel, ultrasonic calibration blocks, proce-l

dures, equipment and materials that were used for the l

inspection are identified in the tables of Appendix E.

4.0 EXAMINATION OF THE STEAM GENERATOR TUBING During the October 1986 scheduled refueling outage 100% of all ac-cessible tubes in steam generators 21 and 22 were examined full length. The examination was conducted utilizing the multifrequency eddy current technique. The probes were all differentially wound bobbin coil design multiplexed at frequencies of 400KHZ,

200KHZ, l

100KHZ and 10KHZ in both the differential and absolute modes. The program was as follows:

1. Cold leg examinations were performed from the seventh support

~

plate on the hot leg side through the tube end on the cold leg side. These examinations were completed using 0.720 inch diam-eter magnetically biased probes. When U-Bend geometries re-l stricted the passage of 0.720 inch probes, other probe diameters l

of 0.700, 0.680, 0.650 and 0.610 inch were utilized to acquire the data. One tube in steam generator 21 (row 1 column 23) was i

only examined from seventh support plate on the cold leg side l

under this program.

2. Hot leg examinations were performed from the seventh support plate on the hot leg side through the tube end on the hot leg side. These examinations were completed using 0.740 inch diam-eter magnetically biased probes. Tube 1-23 in steam generator 21 l

was examined a second time from the seventh support on the cold leg side using a 0.610 inch probe to satisfy the cold leg pro-gram.

i

3. A small sample (approximately 84) of tubes were examined with the rotating pancake coil (RPC) technique in steam generator 22 cold leg. The purpose was to gather supplemental information to develop future techniques in detection and sizing of both bobbin and RPC data.

Westinghouse Electric Corporation was contracted to acquire and evaluate the eddy current data. Westinghouse subcontracted Echoram Technology Inc. to assist in the data evaluation. Conam Inspection l

was contracted to perform a completely independent evaluation of all data acquired. The scope of all the work contracted was com-pleted using remote positioning devices and the Zetec MIZ-18 digital test equipment along with associated acquisition and DDA-4 analysis software.

Summaries of tubes examined, indication distribution, tubes plugged this outage and total tubes plugged can be found in Tables I through IV respectively.

Tube sheet maps and cumulative lists of plugged tubes and indica-tions by depth range can be found in Appendices F an G for steam g

generators 21 and 22 respectively.

Include a list of examination and a statement concerning status of work required for current interval.

This was the second inspection conducted for inspection period one of the 2nd Ten Year Inspection Interval.

The examinations completed 65% of the required pressure retaining components and their supports of the reactor coolant and associated auxiliary systems classified as ASME Class I and II, and FSAR aug-mented examination of main steam and feedwater systems transversing the Auxil-iary Building. Eddy Current examination requirements for steam generator tubes was conducted this outage in accordance with Prairie Island Technical Specifi-a cation Section TS 4.12.

11.) Abstract of Conditions Noted.

Other than steam generator (S.G.) tubes, there were no signs of degradation to systems scheduled for examination.

There were a total of 4 and 20 tubes for S.G. No. 21 and No. 22, respectively, that were found exhibiting wall thinning greater than 45%.

The anomalies detected were:

2 linear MT indications; 2 linear PT indica-tions; 3 hangers with improper load settings; 2 hanger with drawing compli-ances; 1 hanger wi 5 either no load scale ; 3 hangers with loose bolts or nuts; I hanger with nuts missing; I weld with undercut and cold lap; I hanger with a rod bent: 3 hangers with different size spring canisters than the draw-ing; I hanger not welded per drawing; I hanger with undercut; 1 support with cracked grouting; and 1 hanger with no grouting.

12.) Abstract of Corrective Measures Recommended and Taken:

All degraded S.G.

tubes with greater than 45% wall thinning were mechanically plugged, a total of 4 tubes for S.G. No. 21 and 20 tubes for S.G. No. 22.

All anomalies were either corrected or an engineering evaluation was performed to accept "as is" conditions.

The MT and PT indications were corrected by light hand grinding and blending the surface smooth; the hangers that were out of adjustment were readjusted; the hangers with drawing compliances were turned over to drawing control to reflect the 'as found' conditions or were I

accepted 'as is' based on engineering evaluations; loose bolts were tightened; I j the missing nut was replaced.
