The loose nuts and bolts were tightened, and the tilted hanger was straightened. The linear MT and PT indications were removed by light hand grinding and blending the surface smooth. The bolts with major steam gouges and -

linear indication were replaced. All indications were correctad and reexamined with the same method that located them.

The several rounded indications on Pressurizer Safety Line A were accepted as is, based on Westinghouse's evaluation conducted in the January 1980

outage. The indications on the Reactor Pressure Vessel outlet Nozzle Bore Region was also accepted as is, See section 4 for acceptance analysis, i 3.0 ASME CLASS 1 AND 2 COMPONENTS 1

l 3.1 Examination Plan l The examination plan focused on the pressure-retaining components i and their suppor s of tha reactor coolant and associated auxiliary systems classified as A5!P Class 1 and Class 2.

t l - The examination plan was based on the examination requirements of the ASME Boiler and Pressure Vessel Code Section XI, 1974 l Edition through and including the Summer 1975 Addenda, and com-l plied with Prairie Island's Technical Specification, Section TS 4.2.

l The examination is in accordance with the program submitted to the l

United States Nuclear Regulatory Commission on February 1, 1978 I

l entitled, "ASME Code Section XI Inservice inspection and Testing Program and Information Required for NRC Review of Requests for l Relief from ASME Code Section XI Requirements."

3.2 Examination Methods Ultrasonic examination methods and techniques were used to perform the volumetric examinations. The ultrasonic test systems 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 penetrant examinations were performed using color contrast-solvent removable materials. Magnetic particle examinations were performed using e: ther a yote with dry powder or an A-C L-10 coil with fluorescent prepared batn.

All v_sual examinations were aided when necessary with artificial light 1ng and verified for adequacy with an 18% neutral grey card with a 1/32 inch black line.

3.3 Examination Procedures The ultrasonic examination procedure for pipe welds complied with the requirements of Appendix III of ASME Section XI that was issued in the Winter 1975 Addenda. All other examination proce-dures complied with the requirements of the 1974 Edition through ard 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 E.

3.4 Equipment and Materials All equipment and expendable materials used in the examinations are -

listed by either serial number or type along with their respective calibration date or batch number in Table IV of Appendix E.

l The ultrasonic calibration standards used in the examination are l listed in Table II of Appendix E. These standards are owned and l

3.6 Evaluation Any indications disc 1ceed 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 was aided in his evaluation by a calibra-tion performed on a standard reference before each day's examina-tion, checked before and after each individual examination, and at intervals net 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 Docurggiation All examination reports and docamentation are maintained on file by Northern States Power Compeny. Table I of Appendices A, B and D identifies the examinat. ion report number (s) for each item examined. Many of the iteus identify more than one examination report because of the different types of examinations performed on the item.

Table I of Appendix A, B, and D 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 examina-tion requirements. For retrieval purposes, the prefix of the inspection report number corresponds with the year that the insp-ection was performed. The examination report numbers for this outage are prefixed with "81 ". .

bration 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, entitled " Owners" Data Report for Inservice Inspections".

4.0 EXAMINATION OF THE REACTOR PRESSURE VESSEL AND OUTLET N0ZZLES Westinghnuse was contracted to perform the remote ultrasonic and visual examinations of the reactor pressure vessel. The visual examina-tion program consisted of two reactor vessel shell clad patches each bein3 36 square inches. The rer.otely operated ultrasonic device was utilized to perform examinations on the shell-to-flange weld, vessel flange ligaments, outlet nozzle-to-weld, and for investigating for the presence of underclad cracking in the reactor vessel outlet nozzle bore region, ihe examinations were performed in accordance with the applicable requirements of Prairie Island's Technical Specification, Section TS 4.2, and the 1974 Edition of ASME Section XI through and including the Summer 1975 Addenda. There was no reportable indications revealed during all the examinations with the exception of the outlet nozzle underclad cracking examinations. These examinations disclosed 22 discrete reflectors in the cylindrical section of the Loop A nozzle bore and 83 discrete reflectors in the Loop B nozzle bore. There was no Pace 4 of 8

reportable indications detected in the taper regions of either loop A or B nozzles.

The following is a summary of the underciad examination results and bases for evaluation. This information was received by letter from Mr. J.A. Vano, Manager Inspection Services, Westinghouse Electric Corp.

Examinations were conducted from the inside diameter of the nozzle using dual element, transmit-receive, 2.25 MHz, focused immersion search units inclined to generate lonaitudinal waves at a refrac.ed' angle of 55 to 60 . Test sensitivit.y was established on the flat bottom of a 2mm diameter hole drilled just below the clad / base metal interface in a representative calibration block. Secnning was conducted on 3/16 inch increments in both circumferential directions. Any indications equal to or exceeding the primary reference response was recorded. Reflector lengths were measured via a 12 dB drop method. This procedure provides a sensitivity 14 - 16 dB greater than current ASME XI requirements and has been demonstrated capable of resolving reflectors as small as 1 to 2mm deep and 3 to 4tr long.

The fact that reflectors are' confined to areas in the nozzles clad with two layers suggests they may indicate the presence of underclad cold cracking. However, the reflector. are located at depths which indicate they may be confined to the cladding, and further, only half of the reflectors are detectable in both scanning directions. Laboratory studies have consistantly shown that sub-clad cracking is detectable from both directions. Since a definite conclusion regarding the nature of the ultrasonic reflectors is not available, all will be conservatively -

assumed to be planar surface defects just beneath the cladding for analysis purposes.

An ASME XI evaluatibn of these reflectors requires a measurement of their through-wall extent. Current NDE technology does not permit a

direct, accurate, measurement of this dimension thus a reliable method of estimating these depths is necessary.

Assuming the worst case, that of underclad cold cracking, exhaustive l

destructive analysis of nozzle strip clad with multiple layers have demonstrated these cracks are always confined to the depth of the heat affected zone of the second layer of cladding, 0.295 inches (7.5mm) maximum. The Prairie Island Unit II nozzles were clad using a process j with a lower heat input, dual-wire / submerged-arc. Thus an essumption that all reflectors are 0.295 inches deep is conservative for ASME XI l inservice evaluation purposes.

l- The criteria of I;'A-3330 for multiple planar flaws have been applied where necessary and all reflectors or groups of multiple reflectors have been characterized as surface flaws, IWA-3310, with depths equal to O.295".

l The thickness of the bore region of the Prairie Island Unit II nozzles i

is 10 inches. This thickness is determined per Table IWB ~n12, note 2, where t=tni + cn2 Dimension ent' and tn2 were btained from nozzle 2

l fabricacion drawings.

Th3 long3st ultrestnically meccur:d rafisctor obsarv:d in tho outist nozzle bore regions was 1.0". These reflectors have been evaluated per IWB-3512, ASME XI, 1977 Edition. Assuming a depth of 0.295", the allowable a/t value is 3.5% while the actual a/t value for this case is 2.95%.

Reflectors in the vicinity of the safe end welds have been evaluated per IWB-3514.4 (a), which refers to Table IWB-3514.2. The longest reflector detected in these areas was 0.86". Assuming a depth of 0.295", the allowable a/t value is 14.2%, while the actual a/t value for this case is 12.3%.

Thus, based on the conservative assumption that reflector depths are 0.295" (7.5mm), it is concluded that all ultrasonic reflectors detected in the Prairie Island loop A and B outlet nozzle bores meet the inservice acceptance criteria of IWB-3500, ASME XI, 1977 Edition.

Structural Materials Engineering (W. Bamford) perfocmed a fractute evaluation on the locations where the indications were detected, even though it was not required by the rules of Section XI of the code because the indications were small. In the nozzle bore region the critical flaw depth was found to be equal to the wall thickness for normal and upset transients, and to be equal to 2.53 inches for the governing accident condition, the larger LOCA. The crack growth of indications beneath the cladding is negligible, so the following results obtain:

ai = 2.55 ac = 12.15 (wall thickness) ,

ag = 0.295 Therefore the evaluation criteria of IWB 3600 are met:

ag < 0.5 at

~

ag < 0.1 a e In the nozzle safe end region, the critical flaw size for both normal upset and faulted conditions is equal to the wall thickness, because the stresses are very low. The fatigue crack growth is also negligible in this case, so the fellowing results are obtained:

ag = 0.295 ac = 2.53 ai = 2.53 Page 6 of 8

I The criteria used here are based on the calculated stress intensity factors for the observed indication for faulted conditions Kg (a=.295) = 33.0 kai 9in for normal upset conditions Kt (a=.295) = 36.0 kai E K y3 =Kyc = 200 kai Nin at the governing time for both normal and faulted conditions.

Therefore the criteria for integrity are met:

410 Kr (nomal-upset) = 36 Q 10 = 114 < 200 7K (f..lted) =

33 Q 2 = 46.7 < 200.

In conclusion, the reflectors meet the acceptance standards of ASME Section XI 1977 Edition. This conclusion was verified by a detailed fracture mechanics analysis perfomed by Westinghouse for Northern States Power Company. Copies of the procedures, inspection programs, inspection data and evaluation, and personnel certificatio a are con-tained under a separate report prepared by Westinghouse. This report will be maintained on file by Northern States Power Company.

5.0 EXAMINATION OF SEISMIC BOLTING The entire seismic bolting program, partially due to the problems that .

have bear occuring with high strength bolting materials, was scheduled for examination. This program includes the bolting, anchors, nuts, and pins on tne steam generator, reactor coolant pumps, accumulators, and pressurizer support structures. All items were examined visually, and where feasible, by ultrasonic examination techniques. .

la addition, a program for replacing each of the 48 helicoil bolts was scheduled for implementation during this outage. The helicoil bolts (so named because of the helicoil insert utilized in the base metal) form the connection between the steam generator channel head casting and the support structure it rests on. This replacement was scheduled due to the problems encountered during the detensioning program on Unit I's bolts during the September 1980 cutage.

When the problem on Unit I's helicoil boles was identified (September 1980 outage), Unit 11 was shut down and the helicoil bolts on both steam generators were ultrasonically examined. The examinations revealed 1

, bolt without a back reflection, that subsequently sheared off during detensioning, and 2 bolts with a reduced back reflection. These two

~

bolts were removed and a fluorescent magnetic particle examination was perfomed on them revealing a linear indication in the thread relief area adjacent to the bolt head on each bolt. Two of the other 45 bolts were removed and a magnetic particle examination was perfomed on them with no apparent indications. These two bolts were used to replace the two with indications (beca use all three of the bolts with indications were on the same support leg). The remaining bolts were detensioned and reexamined ultrasonically with no further indications.

These bolts were all removed during this outage and fluorescent magnetic particle and an ultrasonic examination was performed on each bolt. The ultrasonic examinations revealed one bolt with a reduced back reflection from the head end. The magnetic particle examinations revealed linear indications in the thread relief area adjacent to the bolt head on 36 of the 45 bolts. The majority of these indications were very small and inter-mittent. All the helicoil bolts were replaced with bolts of an approved design.

All other indications disclosed during the examinations were resolved prior to plant heat up. The loose nuts and bolts were tightened. All indications were corrected and the areas were reexamined with the same method that located them.

This was the last inservice inspection in the Second Period of the First Ten Year Interval. The examinations completed the required pressure retaining components and their supports of the reactor coolant and associated auxillary systems classi-fied as ASME Class 1 and Class 2,100% of the Seismic Bolting program, and 100%

of the required volumetric, surface, and visual examinations of the reactor vessel welds, studs and cladding we.s performed. In addition, both reactor vessel outlet nozzle bore area 3 were examined for the presence of underclad cracking.

11.) Abstract of Conditions Noted.

The results of these examinations indicated that the integrity of these systems was maintained. The following is a list of all anomalies detected:

All anomalies, with the exception of the rounded PT indications on Pressurizer Safety Line A and the indications on the Reactor Pressure Vessel Outlet Nozzle Bore Region, were corrected. The loose nuts and bolts were tightened, and the tilted hanger was straightened. The lirear MT and PT indications were removed by light hand grinding and blending the surface smooth. The bolts with major steam goug(.s and linear indication were replaced. All indications were corre;'.ted and reexamined with the same method that located them.

The several rounded indicaticns on Pressurizer Safety Line A were accepted as is, based on Westinghouse's evaluation conducted in the January 1980 outage. The indications on the Reactor Pressure Vessei Outlet Nozzle Bore Region was also accepted as is, See section 4 for acceptance analysis.

We certify that the statements made in this report are correct and the examinations and corrective measures taken conform to the rules of he ASME Code,Section XI. ,
