Letter to Dr. T. E. Murley from S. L. Daltroff, dLted October 19, 1993, (Supplement to Peach Bottom Unit 2 Response to I.E. Bulletin No. 83-02

Dear Dr. Murley:

This supplement to our above referenced submittal letter of October 19, 1983, S. L. Daltroff (PECo) to Dr. T. E. Murley (NRC), provides the results of the post Induction Heating Stress Improvement (IHSI) ultrasonic examinations and thus completes the Philadelphia Electric Company response to I.E. Bulletin No. 83-02. The enclosed attachments include information extracted f rom General Electric Company report RSFA 83-71, Rev. O, entitled, ' Fracture Mechanics Evaluation and Weld Overlay Design for the Indications in the Peach Bottom 2 Recirculation and RHR Piping Subject to IHSI,' which is included as Attachment C. Philadelphia Electric Company decided to embark on a partial IHSI program to reduce the susceptibility of sixteen (16) selected welds to Intergranular Stress Corrosion Cracking (IGECC). Attachment A of our above referenced submittal has been updated to address: I 8312070172 831118 \\\\ PDR ADOCK 05000277 /\\ G PDR Y t\\

- - ~ _. _ _ %4 -Dr. Thomas E. Murley Page 2 Docket No. 50-277 (1) the welds on which IHSI was performed, (2) the corrective actions taken, if necessary, on welds i receiving IHSI treatment, and (3) the inclusion of items omitted from the previous submittal. Attachment A of this submittal, ' Recirculation, Residual Heat Removal Shutdown Cooling, Head Spray Line, Reactor Water Clean-Up Line, and Core Spray Line Piping Weld Information, .Rev s on 1, ' provides the information requested in Action Item 3 ii susceptibility matrix. [ The results of the volumetric inspection are shown in Attachment A, Table II, pages 21 of 60 through 40 of 60, under the heading "IGSCC Detection." The heading " Remarks" on the same pages provides justification why some welds were not examined. i The post IRSI ultrasonic examinations were performed utilizing inspection teams from General Electric Company (GE), i i Lambert-MacGill-Thomas, Inc. (LMT), and Southwest Research Institute (SWRI). The personnel and procedures utilized by each [ . company were qualified as described in our response to Action Item 1 in our October 19, 1983, submittal. All non-destructive examinations (NDE) were performed to the 1974 Edition of Section XI with Addenda thru Summer 1975. GE I L' and LMT were the prime contractors for these examinations. If the ultrasonic examination discovered evidence of a defect, the other contractor examined the wald to confirm the others' findings. A third contractor, SWRI, was utilized whenever the GE and LMT findings did not concur. Attachment B, " Summary of Ultrasonic Weld Indications," dated October 12, 1983, contains the results of the post IHSI ultrasonic examinations which identified five (5) welds with.IGSCC. The length and depth of each indication is shown, as well as the circumferential location from the weld reference point. In addition, a review of previous ultrasonic examination data discovered one (1) additional weld with IGSCC. Table 1, l ' Peach Bottom 2 Ultrasonic Testing,' n page 11 of Attachment C, l Fracture Mechanics Evaluation and Weld Overlay Desian for the i Indications in the Peach Bottom 2 Recirculation and RHR Piping Subject to IHSI," contains the results of the examination which identified. weld 10-0-2 as having IGSCC. The length and depth of l the indication is shown, as well as the circumferential location. -These six (6) additional cracked welds increases the total number of welds with-IGSCC indications to twenty-six (26).

Dr. Thomas E. Murley Page 3 Docket No. 50-277 4 Attachment C, " Fracture Mechanics Evaluation %nd Weld Overlay Design for the Indications in the Peach Bottom 2 Recirculation and RHR Piping Subject to IHSI," contains the GE document #83-71 (Rev. O) which describes the analysis and overlay designs where required, for disposition of the six (6) additional welds with indications. The fracture mechanics evaluations included in Attachment C were performed in accordance with Appendix X of Section XI of the ASME code and Paragraph IWB-3640, " Acceptance Criteria for Flaws in Austenitic Stainless Steel Piping." The beneficial effects of IMSI stresses were not included in the crack growth calculations. Full structural overlays, where required, were designed and applied to re-establish the code reauired safety factor of 3 for a minimum period of 24 months of continued full-power operation. This design assumes the indications will grow fully circumferential through the original pipe wall. The most limiting ultrasonic data was utilized in the disposition of indications in order to provide an additional degree of. conservatism. Two welds, the 2-AS-3 recirculation suction weld and the 10-0-2 RHR weld were discovered to contain circumferential indications requiring weld overlays in accordance with the fracture mechanics analysis in Attachment C. The four other welds (three located in the recirculation suction lines and the other in a recirculation discharge line), containing circumferential indications, were evaluated using the same fracture mechanics technique and were found to be acceptable for 24 months continued full-power operation. In order to provide an additional margin of safety, full structural overlays were applied to each of the three recirculation suction welds, Nos. 2-AS-4, 2-BS-6, and 2-BD-14. Fracture mechanics evaluation of the - recirculation discharge weld No. 2-AS-7 found the final flaw size to be acceptable beyond 24; months of continued full power operation per ASME Code Section XI, Paragraph IWB-3640. Philadelphia Electric Company plans to operate with the 2-AS-7 weld "as is" for the six to seven months remaining to the next scheduled refueling outage. In addition, this weld will be instrumented with moisture' sensing equipment prior to operation. This weld will be reinspected during the next refueling outage, and will either be replaced.with conforming material or overlaid with a full structural overlay. The overlayswelding was performed using remote GTAW equipment and 0.035". SPA 5.9 Type 308L weld filler metal. The welding procedures, welding aualification procedures, and repair procedures SP 602 P.B. Clad 1.0, Rev. 8, were contained in Appendices D, E, F, G, and I of our October 19, 1983, submittal. A summary of the weld overlay size details is contained in GE Report #83-71 (Rev. O), Figures 8 and 9 in Attachment C. A ~ licuid penetrant examination was performed in accordance with P.B. 83-3.0 (Appendix H of our October, 19, 1983, submittal)

A final ultrasonic examination was performed in accordance with UT-38-(Appendix J, October 19, 1983, submittal) to verify the structural integrity of the completed overlay. An operational hydro will be performed prior to Unit startup. Attachment D, " Safety Evaluation for the Operation of Peach Bottom Atomic Power Station Unit 2," contains the safety evaluation for only these six (6) additional welds. Attachment D of the October 19, 1983, supplement contains the safety evaluation for the previous twenty welds. Together, these two safety evaluations support the six to seven months operation to the next scheduled refueling outage of Unit 2. A written report will be submitted to the NRC staff outlining the plans and ALARA programs necessary for the replacement of portions of the recirculation and other reactor coolant pressure boundary piping systems to be performed during Unit 2 upcoming refueling outage. This report will be submitted at least 60 days prior to_ start of refueling outage. Should you have any ouestions or require additional information, please do not hesitate to contact us.

1. INIRODUCTION i Following the application of Induction Heating Stress Improvement (IHSI) process to the Peach Botton Unit 2 Recirculation Loops A and B, UT (ultrasonic testing) exenination revealed that 5 welds subjected to IHSI had reportable indications. In addition, reevaluation of the UT data on one more weld,10 2, revealed crack indications in the veld HAZ. Table 1 provides a summary of the lengths and depths of the indications at the six welds while Figures la and Ib show the locations of each weld on the Recirculation Piping System. For evaluation purposes, the greater of the depths and lengths reported by the three methods was used. Inspection of Table 1 shows that all indications are circunferential. O t i 1

4 2. SUlGIARY AND RESULTS A fracture mechanics analysis was performed for all six welds and results show that 2 of the welds (2-AS-3,10-0-2) require weld overlays for more than la months of continued operation. Although only 2 welds require overlays, minimum required weld overlay dhickness and width calculations were performed for all 6 velds. This information is provided so that veld overlays can be applied to al) 6 welds if added margin is desired. It is important to note that due to the application of the Induction Heating Stress Improvement (IHSI) process, the GE screening criteria was not used.* The beneficial effects of IMSI stress was not included in the crack growth calculations. A complete discussion of the impact the IHSI process on the fracture mechanics evaluation is given in the analysis. Weld 10-0-2, which was not subjected to IHSI, was analyzed using conventional methods. l l I t l l l O

  • Application of the GE screening criteria shows that welds 2-AS-3 and 10-0-2 require repair and welds 2-AS-4, 2-AS-7, and 2-BD-14 are in the evaluation region. Wold 2-BS-6 was bordering on the evaluation / repair classification.

3. FRACTURE MECHANICS EVALUATION + The purpose of the fracture mechanics / crack growth evaluation of the crack-like indications reported on the piping welds in Table 1 is to determine if a weld overlay is necessary for continued operation. All indications reported in Table 1 are cironsferential in orientation. The GE screening criteria is really not necessary for the evaluation of the indications ezenined in this report because the welds were subjected to the IMSI process. The purpose of IMSI is to change the tensile, weld residual stress on the inner surf ace of the pipe to a compression stress that inhibits IGSCC. The application of IHSI to tasse welds changes the normal assnaptions made on weld residual stresses used in the crack growth calculations. Since the fracture mechanics evaluation is different, it was decided not to use the screening critsria and perform crack growth calculations on all six welds, It is noted that veld 10-0-2, which was not subjected to IHSI, fails the screening criteria. However, a fracture mechanics analysis was performed on this weld and the results show that repair is ne cessary. O Fracture Mechanics Methodoloav 3.1 The fracture mechanics evaluation of the welds reported in Table 1 were performed according to the recently approved Appendix I to Section II of ths ASME Code [1], and the new Paragraph IVB-3640, ' Acceptance Criteria for Flaws in Austenitic Stainless Steel Piping.' These evaluations can be summarized into four basic steps. I. Determine the sustained operating stresses necessary for the crack growth calculations. The sustained operating stresses are those due to pressure, weight, and thermal expansion. No weld residual stress was assnaed (except for 10-0-2) due to the application of IHSI. The veld residual stress assumed for 10-0-2 is shown in Figure 2. This stress information was obtained from the recirculation system piping stress report [2]. l 3

d II. Determiam the stress intensity factor, K, as a function of crack , () depta. These f actors (K) for short, part-through flaws (aspect ratio a/1, greater than 0.1) were calculated using the procedures outlined in Appendix A, Section II of the ASME Code. Tae formulation developed by Bumford and Buchalet [3] was seed. 4 III. Based on the calculated values of K and the crack growth relationsaip j (K vs. da/dt; Figure 3, Reference 4), determins the crack growth as a function of time and establish the final crack size. l IV. Plot the final crack size at the end of 18,000 hours (~24 months) on the appropriate flaw acceptance diagram. The flaw acceptance diagram i is based on the primary stresses (pressure,' weight, and OBE seismic). i 3.2 Fracture Wechanics Evalestion Results Fracture mechanics analyses were performed for all 6 welds. The sustained stresses used in the calculations are presented in Table 2. The results of {} the calculations, printed out for every 1000 hours, are presented in Tables 3 through 8. l A flaw acceptance diagram based on the enveloping primary membrane stress (pressure) plus primary bending stresses (dead weight plus seismic) for welds 2-AS-3, 2-AS-4, ana 10-0-2 was constructed and is presented in Figure 4. Weld 2-AS-4 is seen to be acceptable for 18 months of continued operation as-is. Velds 2-AS-3 and 10-0-2 are not acceptable for 18 months of operation and weld overlays are recommended. A flaw acceptance diagram based on the enevloping primary stresses for welds 2-AS-7, 2-BS-6, and 2-BD-14 was elso constructed and is shown in Figure 5. All three welds are seen to be ecceptable for 24 months of continued operation as-is. e C:) 4 -~

.~ J 3.3 Ilmosct of the IMSI and Shrinkane Stresses.on the Fracture Mechanics O i iv i-The application of IESI to the welds in Table 1 where crack-like indications have Isen reported changes the usual assumptions made regarding weld residual stresses. Figure 2 shows the asial residual distribution based on the experimental dats her large diameter (>16 inch) pipes reported in Ref erence 4. This is the through-wall distribution that is normally assumed for crack growth'cIlculations in welds without IMSI. Figure 6 shows the residual stress vi distribution that is produced by the IHSI procssa. Note that IMSI virtually ~ reple'ces the residual stresses due to solding 'with a beneficial compressive stress on the inner surf ace. This analysis has conservatively assumed that /' there.are no residual stresses / resent in the veld locations. / Er ination of Fiscre 6 shows that the IHSI stress is compressive for only 50% of the wall thickness; the remaining portion is tensile. In crder to properly account f or the IMSI stress variation, the stress intensity f actor should be determined as a function of crack depth. Figure 7 shows K vs. a/t for the stress shows in Figure 6. It is seen that, the stress intensity factor is compressive for crack depth up to S05. Since nazimum crack depth of the IHSI treated welds is 50%, it is conserv$tive to neglect the benefit IHSI stress in the crack growth analysis. i l l Finally, it is necessary to account for shrinkage stresses at the six weld locations in Table 1 due to the installation cf weld overlays on other l portions of the recirculation piping system. All of the indications reported l in Table 1 are on large diameter (20-28 inch) pipes. Previous analyse s have J shown that sacuat of sustained stress due to shrinkage is small. Furthermore, its effect on the crack growth calculations ka known to be negligible, so this smalysis did not include any shrinkage stresses in the fracture mechanics analy si s. This is further supportd by near,ared shrinkage results on 28-inch overlays already applied to other weld locations. This data shows azial shrinkage values across the overlay to be in the range of 0.12-0.19 inch which is much lower than shrinkage previous 1) measured and 3 valuated for the Peach Botton Unit 3 recirculation and RER systems.

4. VEI4 OVERLAY ANALYSIS O The depth of a in11y circumferential erack at which met section collapse occurs is a function of the pipe material flow stress, the overall wall thickne ss including the weld overlay, and the primary locds. The primary f membrane stress (P,) is due to pressure, and the primary bending stress is the sum of the dead weight and seismic (OBE) stresses. Paragraph IBW-3640 of Appendiz 1 to Section II, Reference 1 contains tables of the allowable circumferential flaw depth to pipe thickness ratios (t/t) for various applied primary stress ratios: (P,+ P IIS. The recirculation b m piping welds are subjected to primary loads where the (P, + P I/S

Instead, the allowable flaw depth ratio aust be calculated from the actual applied loads, as described in Reference 5. Equations (1) and (2), from Reference 5, define the relationship for a fully circumf erential flaw. O .ut o g p= (1) 2-f i l (2 - ) sin p (2) P = b where og = Material Flow. Stresses = 3 S, P,= Primary hombrane Stress P = Primary Bending Stress b t = Total Thickness (pipe wall + veld overlay thickness) 1 Using these equations, the minimum required weld overlay thickness was 6

determined by an iterative method in which (i) the circumferential flaw depth (} is assumed to extend through the original pipe wall, (ii) the total thickness 't' equals pipe wall + veld overlay thickness, (iii) the applied primary stresses are adjusted for the new thickness, and (iv) a safety factor of 3 is applied. The iterative calculations wre performed at each of the 6 weld locations , reported in Table 1. The results of the calculations identified the minimum required overlay Unickness necessary to maintain the ASME Code safety factor of 3.0. This minimum required overlay thickness was then used as a basis for selecting the recommended / applied overlay thickness. Tables 9-14 present the results of the iterative calculations while Figures 8. and 9 present the veld overlay designs for each of the 6 welds. Note that veld overlays are recommended only for velds 2-AS-3 and 10-0-2. O l l O 7

5. CONCLUSIONS Wold overlay designs are provided for velds 2-AS-3 and 10-0-2. Justification of operation as-is is provided for velds 2-AS-4, 2-AS-7, 2-BS-6, and 2-BD-14. This assures that the, safety margins of the ASNE Code are maintained for is 2 months of continued operation. . If PECO thooses to apply weld overlays on these welds for added margin, in11 structural ovetiay designs are also provided in this report. i O l l l l l [ O S

ATTACHMENT D O PRACli BOTTOM - UNIT #9 Safety Evaluation for the Operation of Peach Bottom Atomic Power Station Unit #2 i l O l l l l l l O 1

SURJECT: Safety Evaluation for the Operation of p)s Peach Bottom ' Atomic Power Station Unit #2 -s -INT RODUCTION Philadel nhia Electric Company initiated a cartial Induction Ileating Stress Improvement Program (IHSI) on sixteen (16) -uelds as part of the weld overlay repair outage in order to reduce the susceptibility of-these welds' to Intergranular-S tress Corrosion. Cracking. (ICSCC). Initially these welds were volumetrically examined and found to be acceptable. The 16 welda on whichIIHSI was performed are located in -the recirculation auction and discharge lines and one RHR return 11tne. A volumetric' examination was performed upon completion of -the IIISI and 5 of these 16 welds were found to contain crack-like indications. In addition, all of the ul trasonic data for the 126 welds previous 1v examined as nar t of the IE nulletin 83-02 were reviewed. As a resul t of thi s revi ew, i t was decided that reflectors on wpld 10-0-?,. nroviouqly evaluated as aeometric in nature should be conservativelv dispositioned as. crack-like reflectors. Thene crack-like reflectors were later confirmed to be crack indications by independent ultrasonic examination. Philadelphia Electric Company contracted General Electric Company to analyze these indications and to provide their recommendations for disposition. General Electric analyzed and:propoced tcmnorary weld overlav repairs in accordance wi th Section XI of the ASMR Roiler and Pressure Vessel Code on RilR weld 10-0-2 and recirculation weld 2-AS-3. Philadelphia ~ Electric Company also elected to overlay recirculation' suction welds 2-Ab 1, 2-BS-6, and 2-BD-14. Procedures were prepared to perform these temporary weld - overlay repairs with the concurrence of the on-site representative of Hartford Steam Boiler Inspection & Insurance Company and the Nuclear Requlatory Commission. The weld overlays were-designed and sized as full structural overlays which provide the saf ety margins required by the ASME Code. Practure machanica evaluations havn verified that these 5 wolds have the necessary structural reinforcements for 24 months of full nower operation. The ' remai ni nq reci rcul ati on suction lino weld (2-AS-7) was shown to he acceptable "as is" for 24 months of full power onoration. The final flaw size for this oeld is well within the allowable limits of ASME Code Section XI, App. X. t .r - (-)

n 'u/ Philadelphia' Riectric Company han elected to continue onoration of this weld "an is" for only the 6 to 7 months run to the next s cheduled refuel outage. Philad elnhi a Electric will reinspect this wold during the next refuel outage and will either replace with conforming material or overlay with a full structural overlav. BACKGROUND Of the six welds that showed repor table indications, three of these are located in the "A" recirculation cuction li ne. (2-AS-3, 7-AS-4, 2-AS-7), one is located in the "B" recirculation cuction line (2-BS-G), one is locate,1 in the "0" recirculation discharge line (2-BD-14), and the remaininq weld (10-0-2) is located in the Residual Heat Removal (RHR) nuction line. Four welds (9-AS-3, 2-AS-4, ?-AS-7, 2-ns-6) are located in the r3 circulation suction lines. The recirculation nuction lines are ?R" in diameter by 1.00" minimum wall thickness (M.W.T.) TP 304 stainless steel nipe material. A O.439" thick by 4.5" long weld overlay was designed for the ?-AS-3 and ')-AS-4 weldc and a 0.375" thick by 4.G" lonn weld overlav was deniened for the 2-DS-6 wel d. These weld overlavn are full structural overlavs which can sustain a n() throuqh wall fully circumferential flaw and provide the ASME Code required nafety factor of 3 for ?4 months o f f ull power onoration. Weld ?-hD-14 is located in a recirculation discharge line 29" in diameter by 1.?.5" nominal wall thi ckne ss,. TP 304 ntaintenu nteel pipe material. A O.439" thick by 4.5" long weld overlav wan deciqned for the ?-DD-14 weld. This overlay 17 al so a full structural overlav which can sustain a throuqh wall fully circumferential flaw and provide the ASME Code requi red naf ety f actor of 3 for 24 months of full power operation. Weld 10-0-? is located in the RHR quction line which is a 20" diameter by 0.775" M.W.T. ASTM Type A359, qrade TP 304 ntainless steel pipe material. A 0.350" thick by 3.5" long weld overl ay van designed for thin weld. This overlay is a full structural overlay which can sustain a through wall fully ci r cum f nrenti al flaw and provide tho ASMC code requirca safety factor of 1 for 94 months full nower onoration. The final flaw nize of weld ?-AS-7 has been determined to be well within the allowable limits of the ASME Code Secti on XI, Paranraph IWR-3640 for 24 months of full power [) opera ti on. Tho General El ectric f racture mechanics anal vni n for this weld utilized the most limiting condition for crack growth anal yn i s. Therefore, this techniqua should be considered conservative. Philadelphia Electric Company

m _3- /m s \\_/ requestu continued full power operation for the six to seven months run to the next refueling outage, at which time weld ?-AS-7 will he re-innpected and will' either he replaced with conforming material or overlaid with a full structural overlay. EVALUATION The ul trasonic examination techniques used in the detection of the crack-like indications have been demonstrated to be canabl e o f finding IGSCC cracking at Battello Columbus Laboratories or the EPRI NUP Center in Charlotte, North Carolina. The technicians par ticipatinq in the examination have been certfied as being able to detect service-induced IGSCC in accordance with NUREG IE Bulletin 03-q?. Indonendent ultrasonic examinations were performed by both Lambert-MacG ill-Thomas, Inc. and General Electric Company personnel on all welds that were found to contain i ndi ca ti ons. This was done to obtain the maximum con fidence in crack detection. Where there was a discrepancy, a third vendor, Southwest Research Institute, was called in to (,,) provide additional verification, v It is recognized that under field conditions, one team may report crack indications of'different lengths and depths than that previously reparted by another independent team. This is because equipment may varv slightly as to transducer frequency and beam spread; calibration sensitivity may he dif f erent dependinq on whether sido drilled holes or notches were used; environmental conditions such as high radiation levels, resnirator recuirements, etc. may all lead to di f f erences i n reported crack cnaracterization. In addition, once an indication has been evaluated as being a crack, sizing for lonaths may tend to be less critical and adjacent I.D. qnometric reflections may he i ncl uded, particularly if the recording sensitivity levels are high. The crack characterization method used by Lambert-M acG ill-Thoma n, Inc., Gennral Electric Company, and Southwest Research Institute to describe crack indications was conservativo since it ignored tho down hendinq of l ultrasound as it is t ra nsmi t ted through weld material, i Therefore, the crack indications as characterized for fracture analysis rcpresent a maximum depth indication since straight line plots wern used in their characterization. In all cases, the most limiting ultrasonic data was used in the f') f racture mechan ics oval ua tion. v i

A 9 4 r - (_)s ~ The welding procedures and welders used to perform the weid overlays were qualified to procedures which meet the requirements of the ASME Code, Section IX 1980 Edition including the Winter 1981 Addenda. The welding procedure required an adequate ' cooling water flow inside the pipe during welding to produce compressive stresses on the inside Q surface of the pipe similar to those nroduced by IHGI. Crack propagation into the weld metal is not likely to occur by ICSCC since the high ferrite weld material is not susceptible ~ to IGSCC. The fracture mechanics analysis was done in accordance with Section XI, Appendix X to the ASME Code. The analysis performed hy-General Electric Company has been independently reviewed by philadelphia Electric Company and Structural integrity Ascociates of LaJolla, Cali fornia. CONCLUSION 1. The Peach Bottom Unit #2 ultrasonic exanination was conducted hv personnel trained in the detection of IGSCC cracking and certified by ultrasonic technique demonatration at Battelle Laboratories in Columbus Ohio, and the EPRI NDP Conter in Charlotte, N.C., in accordance with IE Bulletin 93-02. The procedure and instrumentation used in this f') examination han been proven capable of detecting A-and characterizing intergranular stress corrosion cracking. 2. The crack characterizations and the fracture mechanics analyses utilized are inherently con n er va ti ve. The fracture mechanics analysen performed on the crack indications and the weld overlav repairs possess an inherent safety factor of three. 3. The overwhelming laboratory and industry experience to date has shown that IGSCC will f ail in a leak before break manner. It-can he concluded that Unit #? of the Peach Bottom Atomic Power Station can operate at full-load power for the six to seven months run to the next scheduled refueling outage with reasonable assurance that the health and safety of the nublic will not he endangerna. m.- . ~ ~... - _. _.. _ _ _ _., _ _ _ _ _ _}}
