INSERVICE INSPECTION - EXAMINATION
SUMMARY
PRAIRIE ISLAND NUCLEAR GENERATING PLANT - UNIT 2 January 2 to February 4,1980
1.0 INTRODUCTION
This report is a summary of the examinations performed during the fourth scheduled inservice inspection at the Prairie Island Nuclear Generating Plant - Unit 2.
This was the second inservice inspection conducted during inspection period two.
The examinations were performed during the plant's 3
fourth refueling outage from January 2 to February 4, 1980. Prairie Island-Unit 2 began commercial operation on December 21, 1974.
This report identifies the components examined, the examination methods used, the examination report number; and, summarizes the examination results for each of the following areas:
1.
Pressure retaining components, supports, and bolting of raismic supports classified as ASME Class 1, and reactor coolant pump flywheels.
2.
Reactor pressure vessel interior surfaces and internal components.
3.
Feedwater piping circumferential butt welds and piping base metal as required by IE Bulletin No. 79-13.
4.
Eddy current examination of steam generator tubing.
2.0 ASME CLASS 1 COMPONENTS AND FLYk"dEELS 2.1 Examination Plan The examination plan focused on the pressure-retaining components and their supports of the reactor coolant and associated auxiliary systems classified as ASME Class 1.
In addition, examinations were performed on seismic bolting of supports for ASME Class 1 components, as required by DRO Bulletin No. 74-03, and on the reactor coolant pump flywheels as required by Prairie Island's Technical Specification, Table 4.2.1.
The examination plan was based on the examination requirements of the ASME Boiler and Pressure Vessel Code Section XI,1974 Edition through and incr: ding the Summer 1975 Addenda, and complied with Prairie Is-J land's Technical Specification, Section TS4.2.
The examination is in accordance with the program submitted to the United States Nuclear Reg-ulatory Commission on February 1, 1978 entitled, "ASME Code Section XI Inservice Inspection and Testing Program and Information Required for NRC Review of Requests for Relief from ASME Code Section XI Require-ments."
2.2 Examination Methods Ultrasonic examination methods and techniques stre 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 Page 1 of 8
height (amplitude) and the wcond channel was calibrated to indi-cat e met al path (ranne) to t he 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 examina-tions were performed using color contrast-solvent removable materials.
Magnetic particle examinations were performed using a yoke and dry powder.
All visual examinations were aided when necessary with artificial lighting and verified for adequacy with an 18% neutral grey card with a 1/32 inch black line.
2.3 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 the other examination procedures complied with the requirements of the 1974 Edition through and in-cluding 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.
2.4 Equipment and Materials All equipment and expendable materials used in the examinations are listed by either serial number or type along with their res-pective calibration date or batch number in. Table IV of Appendix E.
'The ultrasonic calibration standards used in the examination are listed in Table 11 of Appendix E.
These standards are owned and maintained by NSP at the plant site.
2.5 Personnel Northern States Power Company contracted Lambert, MacGill, Thomas, Inc. to perform the examinations. Hertford Steam Boiler Inspection and Insurance Company, representing ANI, provided the Authorized Inspection.
All personnel involved in the performance or evaluation of exam-inations 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.
2.6 Evaluation Any indications disclosed in the examinations were evaluated by the examiner at that time, in accordance with the rules of the f
procedure and ASME Section XI.
e The ultrasonic examiner was aided in his evaluation by a calibra-l tion performed on a standard calibration block 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 p&rt of the inspection report, and permitted further evaluation.

2.8 Summary of Results There were no signs of degradation to systems scheduled for exam-ination. The only anomalies detected were: one nut not flush in RTD Cold Leg A Hanger "B1" (line 2-2RC-7A); two loose nuts in RTD Hot Leg B Hanger "Al" (Line 2-2RC-7B); three nuts not flush on Reactor Coolant Pump 22 Through Anchor Bolts, one linear PT indi-cation on Pressurizer Spray Weld 22B (Line 3-2RC-5); and five linear and severtl rounded PT indications on Pressurizer Safety Line A Welds 1 and 1A S.E. (Line 6-2RC-20A).
All indications, with the exception of the rounded PT indications on Pressurizer Safety Line A, were corrected. The nuts on Hangers "B1" and "Al" and the Through Anchor Bolts were all tightened.
The one linear PT indication on Weld 22B and the five linear PT indications on Welds 1 and 1A S.E. were all buffed off the surface.
All these indications were corrected and re-examined with the same method that detected them with no further indications.
The several rounded indications on Pressurizer Safety line A vere determined by etching the surface, to be located in the nozzle casting within " from the inconnel weld. The area was radio-graphed to aid in evaluation and possible repair. The radiographs were reviewed and the indications were determined to be gas poro-sity. The porosity was also determined acceptab1<s to Class 1 ASTM E446 Reference Radiographs for Category A gas porosity. Westing-house was contacted to aid in evaluation. They tecommended that' the porosity indications be accepted as is, based on the PT exam-ination results, radiographs, visual examination with 10% magnifi-cation, and ASME Section XI acceptance criteria.

3.0 EXAMINATION OF THE REACTOR VESSEL INTERNALS Westinghouse was contracted to perform a visual examination of the reactor vessel internals. The examinations were performed with under-water television cameras and a video tape recording system.
Examinations were performed on representative regions of those interior surf aces and internals made accessible by the removal of components during normal refueling operation, as required by Item 1.15, Category N of Table 4.2-1 of the Plant Technical Specification.
The upper internals assembly support columns, guide tubes, thermo-couple conduits, alignment keyways and fuel assembly guide pins were all examined when the assembly was removed from the vessel and located I
on the storage stand. Guide tubes and support columns selected for examination included those subject to the highest flow loads and those considered to be subject to an " average" hydraulic loading. Guide tubes at the core locations of the " slow" nnd " fastest" drive lines were also reviewed. This inspection was to observe any evidence of physical dis-tortion and integrity of the fastening and locking devices.
Examinations were made of representative conduit runs and RTD's to verify freedom from distortion and integrity of the fastening clamps. The upper core plate alignment keyvay and fuel assembly guide pins were examined for any indication of galling or distortion.
Representative areas of the lower internals were examined above the fuel assemblies and to the extent accessible. Examinations were per-formed on the head and vessel alignment pin mating surfaces and attach-ments, upper core plate guide key, flange to core barrel weld, core barrel flange flow nozzle welds and the core barrel mid-plane weld were reviewed to verify their integrity and freedom from corrosion or dis-tortion.
The reactor vessel cladding at the 67 and 247' irradiation specimen sccess plug locatione was scheduled for examination. Due to equip-ment malfunction, these examinations were rescheduled for the next scheduled refueling outage.
Copies of the examination procedure, personnel qualifications and examination results is maintained on file by Northern States Power Company.
4.0 IE BULLETIN NO. 79-13 EXAMINATIONS - FEEDWATER PIPING All examinations required by IE Bulletin No. 79-13, Revision 2, were l
completed for Prairie Island Unit 2 during this refueling outage.
These examinations were performed on feedwater circumferential butt welds, supports and basemetal classified as ASME Class 2.
Radiographic examinations were performed on the feedwater pipe-to-nozzle welds and of adjacent pipe and nozzle areas. The radiographic examinations were performed using a double wall exposure, single wall viewing technique. An Iridium 192 source was used in conjunction with multiple loaded Kodak "M" film. In addition, the radiographic examinations were performed to the 2T penetrameter sensitivity level; I
Page 4 of 8
and, where geometry permitted, for a distance equal to two wall thickness on each side of the weld. The radiographic examination procedure and acceptance criteria complied with the requirements of ASME Section III, Subsection NC,1974 Edition through and in-cluding the Winter 1976 Addenda.
The above areas were also ultrasonically examined in accordance with Appendix III of ASME Section XI, 1974 Edition through the Summer 1976 Addenda. The ultrasonic examination was performed using a calibration block fabricated to resemble the pipe-to-nozzle weld geometry, includ-ing the cosnterbore-taper area. In addition, these areas were visually and magnetic particle examined in accordance with ASME Section XI, 1974 Edition through the Summer 1975 Addenda. The results of these examinations showed no evidence of cracking. The magnetic particle examinations did, however, reveal several material irregularities I
on the outside of the pipe and nozrle. These indications were buffed out and re-examined with no further indications.
Radiographic examinations were also performed on those areas required by Bulletin Item 2.a.
These examinations, of feedwater loop B, consisted of the piping base metal from the auxiliary feedwater connection to the pipe-to-nozzle weld. The remainder of this line is encapsulated with guard piping and could not be examined. The con-tainment penetration-to-pipe weld, the circumferential butt welds from the last support to the steam generator, and the piping base metal from the auxiliary feedwater connection to the pipe-to-nozzle weld were all examined on feedwater loop A.
All these areas examined by radiography were also examined by visual, ultrasonic, and magnetic particle methods referenced above. The results of these examinations revealed no evidence of cracking or other unacceptable indications.
All main feedwater piping supports and restraints in containment were examined visually in accordance with ASME Section XI, 1974 Edition through Summer 1975 Addenda. All accessible support attachment welds to the main feedwater pipe were also magnetic particle examined. During these examinations, the following minor descrepancies were noted: one missing nut on Loop A Hanger "K"; two loose nuts on Loop A Hanger "A";
two loose nuts on Loop B Hanger "A",
and, one nut not flush on Loop B Hanger "G".
All indications disclosed during the examinations were resolved prior to plant heat up.
The missing nut was replaced and the loose and not flush nuts were all tightened. All these areas were re-examined with the same method that detected them with no further indications.
Northern States Power Company contracted Peabody Testing Services to perform the radiographic examinations and Lambert, MacGill, Thomas, l
Inc. performed the remainder of the examinations. All personnel involved in the examinations are listed in Table I of Appendix E.
All examination reports and documentation is maintained on file by Northern States Power Company. The radiographs were filed with the Work Request Authorizations; Feedwater loop A with C6357-FW-Q and Feedwater Loop B with D006-FW-Q. Table I of Appendix B identifies the items examined and the corresponding report numbers that are prefixed with "80 ". Table 11 compares the baseline examination results with the results obtained during this examination and Table III identifies the isometric drawings used for the examination.

5.0 EXAMINATION OF STEAM GENERATOR TUBES Eddy current examinations of steam generator No. 21 and 22 tubing was also performed during this outage. In addition to complying with Technical Specification requirements, the examination plan was focused on the peripheral tubes in the inlet side of both steam generators.
These examinations of the peripheral tubes were planned to determine if there were any signs of tube damage due to foreign objects.
Westinghouse, along with technical support from Zetec Corporation, was contracted to perform and evaluate the data from the eddy current examinations. These examinations were performed using Westinghouse's new multi-frequency eddy current testing system. This system provided increased analytical capability for determining tube integrity. The four frequencies and their mcdes that were used for each examination were 400 KHz,100 KHz and 10 KHz in the differential mode and 100 KHz in the absolute mode.
In addition, Westinghouse was contracted to perform a visual examina-tion, using mirrors and fiber optics, of both steam generators to detect the presence of foreign objects.
During the completion of the eddy current inspection for the inlet side of S.G. No. 21, one tube (row I column 1) was detected as having a 66%
OD indication approximately 17 inches above the tube sheet. Due to the location of this tube and the indication, and with no other indications detected, foreign object damage was suspected.
(This tube damage was later confirmed as being caused by the improper installation of the tube lane blocking device which is a plate assembly used to redirect flow across the tube sheet.) Thus, the examination plan for the outlet side of S.G. No. 21 was increased to include the entire periphery of the tube bundle.
The results of the tube inspection for the outlet side of S.G. No. 21 revealed signs of tube deterioration in six of the peripheral tubes.
These indicstions were located at either the first or second tube support. The inspection plan of the outlet side was expanded until it was sufficiently demonstrated that this tube deterioration was primarily confined to the tubes at the periphery of the tube bundle at the first and second tube supports.
A similar inspection was performed on S.C. No. 22 and resulted in similar findings. Table I identifies the percentage of tubes that were inspected and Table II provides a tabulation of the number of deteriorated tubes for each steam generator.

. amu The plugging criterion of the Technical Specification is 50% of tube wall thinning. Additional conservatism was used and all tubes that had areas of wall thinning greater than 43% were plugged.
In addition, as a preven-i tive measure, the tubes that are directly in line with the tube lane block-ing devices, which are the row 1 column 1 and the row I column 94 tubes, were plugged in both steam generators.
(This measure was taken even though improvements in design were made to assure proper location and locking of these blocking devices.) Table III identifies all the tubes that were plugged during this outage.

Examination Dates 1-2-80 to 2-4-80 9.)
h.spection Interval 12-21-74 to 12-21-84 10.) Abstract of Examinations.
This was the second inservice inspect 1.a in the Second Period of the First Ten Year Inspection Interval. The examinations completed approximately 30% of the required pressure retaining components and their supports of the reactor coolant I
and associated auxillary systems classified as ASME Class I.
In addition, 100%
of the feedwater piping welds and base metal required by IE Bulletin No. 79-13, 100% of the required Seismic Bolting Program, 100% of the reactor coolant pump d
flywheels, and 100% of the required visual examinations of the reactor vessel internals was performed. Eddy Current examination requirements for steam gen-erator tubes during this outage was also completed in accordance with Prairie Island Technical Specifications, Section T.S. 4.12.
11.) Abstract of Conditions Noted.
Other than steam generator (S.G.) tubes, there were no other signs of degradation to systems scheduled for examination.
The eddy current inspection revealed for the first time tube deteriation. This deteriation was determined to be tutu wastage (corrosion) and confined to the cold Icg (outlet) side at the outer periphcry of the tube bundle for both S.C.'s.
There were a total cf 10 and 43 tubes for S.C. No. 21 and No. 22, respectively, that were found exhibiting wastage;t20% of tube wall. One tube in S.G. No. 21 was found to have been damaged by a loose flow lane blocking device.
The only anomalies detected were: one nut not flush in RTD Cold Leg A, Hanger "B1"; two loose nuts on RTD Hot Leg B, Hanger "Al"; three nuts not flush on Reactor Coolant Pump 22 Through Anchor Bolts; a missing nut on Feedwater Loop A, Hanger "K"; two loose nuts on Feedwater Loop A, Hanger "A"; two loose nuts on Feedwater Loop B, Hanger "A"; one nut not flush on Feedwater Loop B, Hanger G; one linear PT indication on Pressurizer Spray Weld 22B; five linear ai.d several rounded PT indications on Pressurizer Safety Line A Welds 1 and 1A S.E.,
and several linear MT indications on Feedwater Loop B Weld FW 133.
12.) Abstract of Corrective Measures Recommended and Taken.
All degradated S.C. tubes with wall thinning or damage > 43% were explosively plugged. The locating and locking mechanism for the flow lane blocking device was improved, and as a preventive measure the tubes that are directly in line with the tube lane blocking devices (Row 1 Column 1 and Row 1 Column 94) were plugged. An augumented water chemistry sampling and testing program for the Plant's secondary water system has been established to determine the cause and source of the wastage (corrosion); so that preventive action in the future can.
y
be taken.
i All anomalies, with the exception of the rounded PT indications on Pressurizer Safety Line A, were corrected. The locse nuts on the Hangers and on the Through Anel Bolts were all tightened. The missing nut on Hanger "K" was replaced.
The
- linear PT indication on Weld 22B, the five linear PT indications on Welds 1 anu 1A S.E. and several MT on Feedwater Loop B Weld FW 133 were all buffed off j
the surface. The several rounded indications on Pressurizer Safety line A were i
accepted as is, based on the PT examination results, radiographs, visual exam-inations with 10% magnification, and ASME Section XI acceptance criteria. The above hangers that had indications requiring corrective action will be reexam-ined during the next scheduled outage.
