2.5 Examination Results and Corrective Actions Examination area coverage was provided, to the extent practical, in accordance with the requirements of ASME Section XI and Code Case N-408. In those cases where physical conditions of the component restricted examination of the required area, the amount of coverage achieved was assessed. Appendix 2 D, ISI Examination Limitations, contains a detailed account of all examination limitations (UT, PT, and MT) encountered during 1RE03 weld examinations.
All UT indications determined to be recordable, regardless of signal amplitude, were investigated by SwRI to determine the nature of the reflector.
No reportable indications were detected by volumetric (UT), surface (PT and MT), or visual (VT) examinations.
2.6 Certification of Inspections ASME Section XI NIS 1 forms, " Owner's Report for Inservice Inspections", have been prepared to certify the STPEGS 1 weld ISI examinations described in this section of the Summary Report.

SUMMARY
OF INSERVICE EXAMINATION LIMITATIONS The following tables provide details on the limitations which were encountered during the inservice examinations (ISI) at the South Texas Project Electric Generating Station (STP), Unit 1. Each table of this summary provides the following information as described: folumn 1 - Class / Category / Item No./ Examination Requirement Identifies the ASME Section XI Code Class, Category, item Number, and Examination Requirement (volumetric or surface) for the specific examination area listed in Column 2. This information is derived from Tables IWB-2500-1 and IWC-2500-1 of the 1983 Edition of ASME Section XI (with Addenda through Summer 1983), and Tables 1 and 2 of Code Case N-408. Columql - Line No./ Subassembly Weld Identification Weld ID Figure Weld Configuration Examination Method Provides information for each examination area by line number (piping) or subassembly number (vessel), unique weld identification number, SwRI weld ID figure reference, weld configur ? ion (pipe-to-tee, head to-shell, etc.), and examination method (UT, UT/PT, or UTiM1; Column 3- - Exam Type - Lists the Methods of Examinations used for each area by specific angles for.UT (0,45, 45T,60,60T) and surface technique (MT or PT), if required. Column 4 -
% Coverage The extent of coverage for each exam type is expressed in percentages based on the examination volume / area required in Section XI. Depending on method, the percentage coverage may be represented in more than one way.
Surface methods are the simplest and are expressed as a percentage of the required surface area receiving no coverage and the remaining balance from 100% as the total coverage. 2-40
O Ultrasonic coverage is first expressed for each exam type as a percentage of the volume V receiving no coverage, angle beam coverage in one direction only, and angle beam coverage in two directions. These percentages are then used to compute the effective coverage for that exam type. In the case of 0 degree, the effective coverage is equal to the balance of 100% minus the percentage receiving no coverage. The effective coverage for angle beam is calculated from the following formula: c = " +22*b (effective coverage formula, angle beam) where a = one direction only percentage b = two direction percentage Examples: (1) none 1 dir 2 dir 0% 0% 100 % c = 0 + 2 100 = 100% effective coverage , 0 v 1 (2) none 1 dir 2 dir 0% 100 % 0 % c = 100 + = 50% effective coverage 2 (3) none 1 dir 2 dir 50 % 50 % 0% c = 50 + 2*0 = 25% effective coverage The total UT coverage is then expressed as the average of the effective coverage percentages for each UT exam type. Each UT exam type is considered as equal weight in the calculation of the average. [ 2-41
Columnj - Limitation A description of the type of limitation and primary reason for why the coverage was limited is provided in this section. O 2-42

,_ 3.0 STEAM GENERATOR TUBE EXAMINATIONS l
3.1 Introduction This section of the summary report addresses the eddy current ISI of selected tubing in S: cam Generators C and D conducted during the 1991 refueling outage of the South Texas Project Electric Generating Station, Unit 1 (1RE03). It is intended to respond to the reporting requirements of I ASME Code Section XI, IWA-6000 and 4.4.5.5 (b) of the STPEGS Technical Specification. The STPEGS Unit 1 plant design contains four (4) steam generators. Each of the steam generators is a raodel E2 recirculating design generator, designed and fabricated by Westinghouse Electric Corporation of Tampa, Florida. Each generator contains 4861 tubes. The tubing is ASTM SB-163 Inconel material having a nominal outer diameter (OD) of 0.75 inches and nominal wall thickness of 0.043 inches. The examination agency for the IRE 03 eddy current examination of steam generator tubes was Westinghouse Electric Corporation. They acquired the first eddy current data on January 27, 1991. The last eddy current data analysis was performed on January 31,1991. 3.2 Scope of Examinations The STPEGS 1 Ten Year ISI Plan, previously filed with the NRC, describes the ISI program for examination of steam generator tubing. Additionally, a supplemental 151 plan (ISI Outage Plan) entitled," 1991 Outage Plan for the Inservice Inspection of Steam Generator Tubing at the South Texas Project Electric Generating Station, Unit 1" was prepared by Houston Lighting & Power Company (HL&P). The ISI Outage Plan identified the steam generator tube areas expected to be examined and the eddy current examination procedures expected to be used during this ISI. Prior to the beginning of the ISI, tubes were selected in accordance with 4.4.5.2 of the STPEGS Technical Specification (NUREG - 1346) and assigned to the first (6%) sample of tubes in each of the two (2) steam generators to be examined. _ These first samples were lis:ed in the ISI Outage Plan. Because the results of the initial examinations identified oy the ISI Outage Plan could have identified a situation where additional examinations of other tube areas or the same tube areas (with different nondestructive examination techniques or methods) would be required or advisable, the ISI Outage Plan established a method for quickly changing the plan scope or other details during the outage. Changes were made by issuing Outage Plan Change 3-1

l I l n Forms. Three (3) changes were made 'o he ISI Outage Plan during the () outage. Each of the three (3)is included as i opendix 3 A. Tl:e ISI Outage Plan and plan changes are consistent with the requirements of the Ten Year ISI Plan. 3.3 Personnel, Procedures, and Equipment 3.3.1 Personnel Qualifications The Westinghouse personnel who performed eddy current examinations and data analysis were c:rtified in accordance with the requirements of IWA 2300 of ASME Code Section XI and a Westinghcuse certification practice approved by H1AP. In addition, all data analysts were required to have satisfactorily completed (1) specific training in eddy current data analysis and (2) site specific training. The site specific training lecture addressed the specific design and operating history, previous cddy current examination results, and the data acquisition procedure and analysis guideline to be used for the STPEGS Unit I and 2 steam genentors. The site specific training also included hands on review of indications of flaw types which have been experienced at plants of similar design to that of the STPEGS. Successful completion of the site specific course required the passing of a written and practical (hands on) test. The N Westinghouse personnel who performed examinations and data L analysis and their certification levels are listed in Appendix 3 B. l l 3.3.2 Examination and Analysis Procedures For those eddy current examinations which respond to the requirements of the STPEGS Technical Specifications, Westinghouse used the bobbin probe technique in their procedure entitled," Digital Multi Frequency Eddy Current Inspection of Preservice and Inservice Heat Exchanger Tubing"(HIAP Document No. 0120(1)-00172 WNC). l This technique was used in each tube examined to record 550,400, 100, and 10 kHz frequency data using both differential and absolute l bobbin probe coil configurations. The Westinghouse bobbin probe l procedure (0120(1)-00172-WNC) is an alternative to the technique l described in ASME Code Section V, Article 8, I-42, which requires that the probe puil speed not exceed 14 inches per second. Instead, l
- a maximum pull speed of 24 inches per second was permitted. At this i pull speed the digital signal sampling rate must be raised from the typical 400 samples per second to 800 samples per second. This l procedure, using the faster probe pull speed, was demonstrated to the n
satisfaction of the Authorized Nuclear Inservice Inspection (ANII) in V accordance with IWA 2240 of Section XI. 32
The eddy current data analysts worked to HIAP Engineering Instruction El 8.01," Steam Generator Eddy Current Data Analysis Guidelines", Revision 0 including the Analysis Guideline Exception i Forms entitled " Update 2"," Update 3", and " Update 4". The data for l each steam generator tube was analyzed by two (2) Independent analysts in accordance with HIAP Er3 ineering Instruction El 8.02,
" Steam Generator Eddy Current Data Control", Revision 1.
Every system calibration and calibration verification has been recorded ; on a uniquely numbered digital magnetic tape which is stored as a , record. The unique digital tape number is entered on the eddy current data sheet. The date and time of every system calibration and calibration verification has been recorded on a Digital Multi frequency Eddy Current Calibration & Data Analysis I.eg Sheet which is also considered to be a data sheet. The data sheets are also stored as records. They make it possible to locate the calibration data for each tube examination. 3.3.3 Equipment Westinghouse used MlZ-18A eddy current examination it. iruments
- s- to record the raw data and a Heather system to analyze the data. The s MlZ 18A's are manufactured and produced by both Zetec, Inc. and Westinghouce. The Heather system is iaanufactured by Westinghouse.
l Both the MlZ 18A and Heather use digital equipment and software which have a significantly improved dynamic range and signal to-noise ratio as compared to analog systems. The MIZ-18A is capable of being operated at locations remote frorr. the steam generators (e.g., in low radiation areas). Westinghouse used 0.610 inch diameter l magnetic biased bobbin coil probes. However, bobbin probes as small as 0.590 inch diameter were used in a few cases in order to pass the small radiused U bends in Rows 1 and 2. A motorized rotating pancake probe coil (MRPC) was used to characterize one incidence of wear detected at a baffle plate in the preheater of Steam Generator D. ASME Boiler and Pressure Vessel Code, Nuclear Components Code Case N-401," Eddy Current Examination Section XI, Division 1", was used after the digital equipment and the eddy L current tecimique used were demonstrated to the ANIIin accordance with Case N-401. 3.3.4 Calibration Standards The U bend areas of the Row I and 2 tubes in each steam generator have received an in situ heat treatment to improve their resistance to 3-3
I O V stress corrosion cracking. The eddy current calibration standards used were not subjected to that heat treatment. ASME Boiler and Pressure , i Vessel Code, Nuclear Components Code Case N-402," Eddy Current t Calibration Standard Material, Section XI, Division 1" was used after it was demonstrated to the satisfaction of the ANil that calibration standards with and without this heat treatment result in equivalent examinations. Otherwise, the design and material of the eddy curTent calibration standards used meet the requirements of the ASME Code Section XI. . 3.4 Summary of Examinations 3.4.1 Technical Specification Examinations Examinations were conducted of 301 tubes in each of Steam Generators C and D, approximately six (6) percent of the total tubes installed in these two (2) steam generators. The examinations were conducted with the bobbin probe inserted from the hot leg bowl. All of these, tubes were examined over their full length (from tube end to tube end). *he tubes that constitute these groups of 301 tubes consist of the first samples, defined in the ISI Outage Plan, with the following changes: O Steam Row Col. Row-Col. Reason Generator Removed Added D 3 106 4 - 106 Tube 3 - 106 could not be examined full length with-the .610 inch diameter })tobe because of the tight radius U bend. These examinations constitute the portion of the tube examinations conducted which responds to the requirements of the Technical Specification. 3A2 Augmenting Examinations in addiion t to the tube eddy current examinations required by the Technical Specification, several tubes were examined for other reasons. The reasons for performing tube testing not required by the Technical Specification included investigation of possible loose parts, investigation < of the preheater wear phenomenon, inadvertent testing of tubes not listed in the ISI Outage Plan, and the inability to test the full length A of a few tubes originally listed in the plan. Tube areas which were 3-4 w - y- ww fr- g -- -
l examined for reasons other than compliance with Technical O Specifications comprise the augmenting program. In some cases tubes or portions of tubes in the Technical Specification program were also included in the augmenting program. The additional numbers of tubes which were examined over their entire lengths as pr.rt of the auBmenting program only are as follows: Steam Generatgr Smiber Examined 1 C 21 l D 32 The augmenting program included the following numbers of tubes ' which were examined over only a portion of the tube length: Steam Generator Number Exnmined C 1 D 25 , 3.5 Examination Results and Corrective Actions i No flaw indication was detected by the Technical Specification program with a depth equal to _ or greater than 40.perc+mt of the nominal tube wall thickness. No indication of a tube flaw, which was greater than 20%, was y l ' detected by the Technical Specification program. Two (2) tubes contain L indications which were less than 20% in depth. The Technical Specification ! L - 4.4.5.4 a.3 says that a degraded tube means a tube containing imperfections j greater than or equal to 20% of the nominal wall thickness caused by a service induced damage mechanism. Therefore, there were no defective or degraded tubes detected by the Technical Specification or augmenting
- programs. No corrective actions were performed because of any. flaw, 7 detected by the Technical Specification-o: augmenting programs, with a .
L reduction.cf tube wall thickness. Lists, including the locations and depths, of all flaw indications which are characterized as reductions in the tube wall thickness in both the Technical- - Specification and augmenting programs are included in Appendix 3 C , Lists _of all dents and dings detected in each steam generator by both the k Technical Specification and augmenting programs are included in Appendix 3 D. . The location of the indications were recorded relative to the adjacent tube support and baffle plates and anti vibration bars. The tube support plates 3-5 i

l and baffle plates were numbered cons:cutively from 011I to 1011 (on the hot i leg) and from 11C to 23C (on the cold leg) starting on the hot leg side, over the U bends, and down the cold leg side of the steam generator. The anti-vibration bars were numbered AV1, AV2, AV3, and AV4 from the hot leg , to the cold leg side, respectively. Indications in the tubesheet area were recorded relative to TEH or TS11 (hot leg) or TEC or 1SC (co:d leg) depending on whether the indications were at the tube end (E) or secondary face (S). In addition, the vertical distances from these landmarks to flaws were recorded. > i The tubes which were removed from service by plugging prior to this 151 are as follows: Steam Tube Generator Number A 14 32 35 77 44 48 Steam Tube Generatt r Number B 12 102 17 22 28 30 32 78 Steam Tube Gratttator Number .

l q 4.0 COMPONENT SUPPORT EXAMINATIONS () 4.1 Introduction ISI of Class 1,2, and 3 component supports and Ch .tegral attachments of STPEGS-I was performed between December 10,1990 and M. 20,1991. These examinations constitute the third ISI and completion of the first inspection period of the first inspection interval for the Component Supports Examination Program for STPEGS 1. This Section of the Summary Report documents the examinations of component supports performed by H12P OC NDE personnel in accordance with the following documents: (1) HL&P Specification SUO35JS003, " Inservice Inspection Examination of Component Supports of South Texas Project Electric Generating Unit 1 First Inspection Interval', (2) " Examination Plan for the 1991 - IRE 03 Inservice Inspection at the South Texas Project Electric Generating Station, Unit 1" including changes made during the outage (Outage Plan). The HL&P Specification provides a detailed description of the rules for exemption and selection of Class 1,2, and 3 component suppons for ISI. The 1991 Examination Plan is O O an individual Outage Plan for implementing ISI component support examinations as designated in the HL&P Specification. 4.2 Scope of Examinations A total of ninety-four (94) component supports were visuu .y examined. These supports, selected from the Component Supports ISI Examination Plan (5UO35JS0003), constitute approximately fifteen (15) percent of the total piping and equipment supports required to be examined during the first inspection interval. When combined with the component supports examined during the first two refueling outages (1RE01 and 1RE02), approximately thirty-three (33) percent of the total piping and equipraent supports to be examined during the first inspection interval have been examined. ClasL1 Nine (9) Class I piping supports and three (3) Class I equipment support were examined in the following systems: Pipine Equipment Chemical & Volume Control (CV) 2 0 ( Reactor Coolant (RC) 5 3 Residual Heat Removal (RH) 1 0 Safety Injection (SI) 1 0 4-1 L i t

Examination Personnel". A listing of the-personnel who performed visual examinations of component supports, including their certification level, is included in Appendix 4-B.
; 4.3.2 Examination Procedure L; Visual (VT-3 and VT-4) examinations of component supports were performed in .
E accordance with NDEP 9.2 (Rev. 0),." Visual Examination of Component Supports for ASME XI. Inservice Inspection". L-l- 4-2
Summary of Examinations 4.4-4.4.1 Piping and Equipment Supports Eighty-one (81) piping supports and thirteen (13) equipment supports were examined just prior to and during 1RE03 as shown in Appendix 4 A. 4.4.2 Additional and Successive Examinations The results of the visual examinations of component supports performed during 1RE03 did not require that any additional examinations (IWF 2430) be performed or any successive examinations (IWF 2420) be scheduled. 4.5 Examination Results and Corrective Actions One (1) hanger was found with a missing cotter pin which was replaced and the support was reexamined with satisfactory results. Three (3) supports were found with slightly dislodged betuing racer. One of these supports also had a loose jam nut. These three (3) supports were reworked and reexamined with satisfactory results. One support was found with the load pin in contact with another piping line. This support was reworked and reexamined with satisfactory results. One support was found with a small arc strike on the sway strut. An engineering evaluation determined the arc strike to be insignificant and was accepted as is. One support was found with two (2) of eight (8) jam nuts missing. A L work request was issued to install the jam nuts when posdole. RFA's were issued for these conditions as noted in Table 4-1 below. All of the above supports were analyzed to substantiate their integrity for its intended service in the as-found condition and determined to be acceptable. However, rework was recommended in some cases as indicated in Table 41. l I l f V- 4-3 l
