NIS-1 2R07 Section 2 Summary of Conditions Noted During Cycle 7 Inservice Inspection Examination and Tests April 21, 2001 to March 23, 2003

NIS-1 2R07 Section 2 Page 1 of 3 Summary of Conditions Noted Durng Cycle 7 Inservice Inspection Examination and Tests As a result of the examinations performed prior to and during the LGS Unit 2, 7th Refuel Outage, 2R07, there were no reportable conditions observed. Numerous other conditions were recorded and subsequent examinations and/or evaluations determined all conditions to be acceptable.

RPV Closure Head Meridional Weld Indication Summary Manual ultrasonic examinations from the outside surface of RPV closure head meridional welds 'DJ' and

'DH' were performed in accordance with the LGS Unit 2 ISI Program, Specification NE-027. This inspection is required for ASME Section XI.

Scanning for detection was performed in accordance with procedure GE-UT-300 Version 6. Interrogations for indication sizing were performed in accordance with procedure GE-UT-304 Version 3.

Weld DJ had 18 recordable indications. Twelve of the indications were determined to have through-wall dimension. The remaining 6 indications had no determinable through-wall component. All eighteen indications were evaluated and determined to be acceptable to the requirements of ASME Section XI, IWB-3500.

Weld DH had 2 recordable indications. Both indications were determined to have a through-wall dimension. Indication No.1 was in close proximity to the ID surface and a supplemental magnetic particle examination was performed from the near surface to ensure that the indication was not surface connected. Both indications were evaluated and determined to be acceptable to the requirements of ASME Section Xl, IWB-3500.

The indications in both welds were determined to be acceptable to the ASME Code without engineering (finite element) analysis. Accordingly, there are no structural integrity issues. An ECR is not required and operability was not an issue.

Previous ultrasonic examination results were reviewed. Indications were previously recorded in the area containing these indications however, they could not be directly correlated with the current indications.

Due to improvements in examination techniques this change in examination results is not considered to be indicative of changes in the condition of the weld or associated base material. The current examination techniques invoke a new standard (ASME Xl, Appendix Vil) which is considered to be more critical of the examination volume. The current indications do not represent abnormal degradation of the pressure boundary.

RPV O-Ring Indication Summary Inspection of the RPV flanges was performed in accordance with Owner Specified Criteria based on recent Industry Operating Experience. This inspection is not required for ASME or BWRVIP.

Two indications were recorded and found to meet the acceptance criteria of LGS ECR 02-00125,

'Acceptance Criteria for RPV O-Rings".

A Technical Evaluation was performed per AR A1407439 Evaluation 02.

All indications were determined to be acceptable and no structural integrity issues were identified. An ECR is not required and operability was not an issue.

NIS-1 2R07 Section 2 Page 2 of 3 Summary of Conditions Noted Durng Cycle 7 Inservice Inspection Examination and Tests Snubbers Functional Testing of snubbers was performed during 2R07 in accordance with LGS Unit 2 Technical Specification 4.7.4.e. and Surveillance Test ST-1 -103-300-2.

37 Mechanical snubbers (37 Plan), 17 Lisega Hydraulic snubbers (13.3% Plan), and 2 compensating struts (13.3% Plan) were selected for examination as part of the initial sample.

Of the Mechanical Snubbers tested there was one failure (DCA-204-H027, a PSA-35), All 17 Lisega Snubbers were functionally tested with no failures, and 2 Compensating struts were tested with no failures. The one Mechanical Snubber functional test failure resulted in an additional 19 snubbers being tested. There were no functional test failures in the expanded sample.

Regarding the failure of DCA-204-H027:

CR # 148064 was initiated to address the functional failure and Action Request Evaluation No.

Al 361523/E09 was initiated to provide the engineering evaluation required by LGS Technical Specification 4.7.4.g. The results of the engineering evaluation indicate that the piping and associated snubber were acceptable.

The pre-removal visual inspection of DCA-204-H027 revealed a cold setting of 5-9/16 inches that is 2-1/16 inches greater than the design cold setting of 3-1/2 inches. This condition has prompted the inspection of cold settings for several other snubbers connected to the same piping as DCA-204-H027 to determine the extent of condition of the piping displacement. No other snubber cold settings were found to be out-of-tolerance. Replacement of the HV-051-2F050 valves during a previous outage was determined to be the most likely cause of the snubber cold set problem.

Shroud Head Bolt Indication Summary Augmented ISI of the shroud head bolts was performed in accordance with the LGS Unit 2 ISI Program, Specification NE-027. This inspection is not required for ASME or BWRVIP.

Ten indications were recorded and found to meet the acceptance criteria of Specification NE-027.

CR# 00148196 was initiated to document the indications, apparent cause, corrective action, and extent of condition as required per LS-AA-125.

A Technical Evaluation was performed per A/R Al 407435 Evaluation 01.

All indications were found to be acceptable and no structural, bolted connection or loose parts concems exist. An ECR is not required and operability was not an issue.

Core Shroud During the baseline ultrasonic examination (UT) of the LGS Unit 2 core shroud, performed during 2R05, indications considered indicative of intergranular stress corrosion cracking were detected in six of the seven (7)horizontal welds (i.e. girth welds Hi, H2, H3, H4, H5, and H6).

The condition of the core shroud identified during 2R05 was evaluated per NCR LG 99-01153. An updated structural margin analyses, considering additional cycles of crack growth rate and the latest USNRC approved Industry Guidelines, was performed to ensure the condition of the core shroud remained analyzed. The attached report GE-NE 0000-0006-2250-04a, Revision 0, "Structural Evaluation of Core

NIS-1 2R07 Section 2 Page 3 of 3 Summary of Conditions Noted During Cycle 7 Inservice Inspection Examination and Tests Shroud Welds at Limerick Generating Station, Unit 2," was prepared using bounding crack growth rates approved by the USNRC in their Safety Evaluation Reports to BWRVIP-01 and BWRVIP-14. Results of the engineering analysis showed that structural integrity criteria are satisfied through Li2R1O in 2009 for all horizontal welds. Although the structural margins have been demonstrated to be maintained through Li2R10 using USNRC approved Industry Guidelines the reinspection of the LGS, Unit 2, core shroud has been scheduled for six years, Li2RO8 in 2005 based on the requirements of BWRVIP-76 for acceptance by site-specific analysis.

SUMMARY

The core shroud welds at the Limerick Generating Station, Unit 2 (LG2) were inspected during the refueling outage at the end of fuel cycle 5 (1999). Intergranular stress corrosion cracking (IGSCC) was detected at several horizontal welds. The objective of this report is to document the results of the structural evaluation of the cracked shroud welds to demonstrate compliance with BWRVIP-76 [3]. Horizontal welds HI through H7 were evaluated. The echnical evaluations considered the effects of power uprate (PU). It is shown that continued operation in the 'as-is' condition can be justified for at least 3 cycles of operation (end of fuel cycle 8). Although all horizontal shroud welds have been justified for 5 cycles of continued operations (end of fuel cycle 10) based on inspection results of end of cycle 5 (1999), re-inspection of the shroud welds is reconmended at the end of cycle 8. This shroud weld re-inspection interval of 6 years conservatively took into consideration the uncertainties associated with crack growth rates and possible new crack initiations.

2. INTRODUCTION & BACKGROUND The core shroud welds at LG2 were inspected by UT during the refueling outage at the end of fuel cycle 5 (1999). Figure A-] shows a schematic of the various horizontal welds.

Elevation and inside diameter of each weld evaluated are also shown. IGSCC was detected at several horizontal welds. References I and 2 had provided justification for continued operation of the shroud to end of fuel cycle 7 based on evaluations of the limiting H4 weld. The objecti.e of this report is to document the results of the structural evaluation of the cracked shroud welds HI through H6 to demonstrate compliance with BWRVIP-76 [3]. It is shown that continued operation in the 'as-is' condition at these welds can be justified for at least 3 cycles of operation (end of fuel cycle 8).

3. SHROUD GEOMETRY AND MATERIAL INFORMATION The shroud and horizontal welds geometry information is summarized in Figure A-1 of Appendix A. Figure A-I shows the locations of various welds. The shroud material is SA-240 Type 304L stainless steel (Sm = 14400 psi). The shroud diameter, thickness and elevation for each of the horizontal welds are shown in Table 1. A review of the fabrication information indicates that the H7 weld was made at the LGS site, and it connected the prefabricated core shroud structure to the reactor pressure vessel.

4. FLUENCE LEVELS AT VARIOUS SHROUD WELDS The fluence calculations for the H4 weld were reported in Reference 4. The fluence values for H3 weld were extrapolated conservatively from the H4 fluence calculations.

The luence distributions in all the quadrants are identical. For the purpose of structural margin analysis, the metal between azimuths where the fluence levels exceed 3x1020 n/cm' were conservatively removed (i.e., assumed to be thTough-wall cracks). The remaining ligaments were calculated based on crack growth Tates and inspection uncertainties.

5. PLANT WATER CHEMISTRY The Limerick Generating Station, Unit 2 (LG2), has been operating with at least 90%

availability of effective Hydrogen Water Chemistry (HWC) since Apil 2000. The reduced flaw growth rate was used in the structural evaluations accordingly. For operating period from 5/1999 to 4/2000, Normal Water Chemistry (NWC) condition was assumed, and nornal flaw growth rate was used in the calculation of shroud flaws.

6.

SUMMARY

OF INSPECTION RESULTS The Ultrasonic (UT) inspection results for the various horizontal welds are documented in Reference 5. The UT inspections were conducted using the procedures outlined in Demonstration Number 16 in Reference 6.

UT measurement uncertainties associated with Demonstration Number 16 were added to the reported values of indication depths and lengths. The UT uncertainty in the depth direction was taken as 0. 131 inch. The length uncertainty was assumed as 0 degrees, that corresponds to 45° shear wave case. For flaws whose lengths were determined through more than one setting, the placement uncertainty is 0.5 degree. This value was conservatively added at the both ends of all found flaws.

7. APPLIED LOADS AND STRESSES AT VARIOUS WELDS All applicable loads and the critical load combinations used in the evaluation were consistent with the Core Shroud Loads at Horizontal Welds HI through HE report [7].

The load magnitudes used have considered the impact of power uprate. The goveming applicable loads and load combinations evaluated are as shown in Table 2. A brief description of the various loads is provided next.

3

GENE 0000-0006-2250-04a,Rev. 0 7.1. Dead Weight (DW9 Dead weights were based on the input to seismic and dynamic horizontal mathematical model shown in GE drawing 794E776. These are dry metal weights and include appropriate hardware weights.

7.2. DiffereniialPressureLoads (DP^,, DPJ The differential pressures (Delta Ps) across the Core Plate, Top Guide, and the Shroud Head impart vertical upward loading on the horizontal shroud welds. The differential pressure values across these components are obtained from previous evaluations including power uprate evaluation performed for LG2 as indicated in GE report No.GENE-B13-02066-00-02-LTI[7]. The pressures are multiplied by the net area of resistance of the above components in order to deternine the pressure loads across them in the Upset (DP) and and Faulted (DP ) conditions. The welds H1 and H2 are subjected to the Shroud Head Delta P load; H3, H4, and H5 are subjected to the Delta P loads across Shroud Head and Top Guide; Welds H6 and H7 are subjected to Delta P loads across the Shroud Head, Top Guide, and the Core Plate.

7.3. Seismic Loads (OBE, SSE)

The upset condition Operating Basis Earthquake (OBE) loads and the faulted condition Safe Shutdown Earthquake (SSE) loads at each weld location, in the horizontal and vertical directions, were obtained from the Reference 7 analysis report. Both North-South and East-West seismic horizontal motions were considered. All seismic loads reported were generated using time history analysis and peak time history responses.

7.4. SafeO' Relief ValveDischargeHydrodynamicLoads (SR V, SRJADS)

The hydrodynamic loads induced as a result of the actuation of all Safety Relief Valves (SRV) and the loads induced by the actuation of the Safety Relief Valves associated with 4

GENE 0000-0006-2250-04a, Rev. 0 the Automatic Depressurization System (SRVADS ) were included in the evalution. These loads (vertical load and lateral moment) were obtained from the Reference 7 evaluation basis report. Enveloped SRV loads for symmetric and asymmetric conditions were used in the calculations. All SRV loads reported were generated using time history analysis and peak time history responses.

7.5. Annulus Pressurization(AP)

Due to the loss-o'-coolant accident (LOCA) associated with the postu!2ted rupture of recirculation outlet or feedwater piping in the vessel-to-shield wall annulus, an asynmetric, lateral, transient pressure load (i.e., Annulus Pressurization load, AP) is imparted on the reactor vessel. Since the main steam line is above the shield wall, AP load does not apply to main steam line break LOCA. These loads were obtained from the Reference 7 evaluation basis report. There are no vertical loads associated with AP condition. All AP loads reported were generated using time history analyses and peak time history responses.

7.6. AcousticLoad (AC) and FlowInducedLoad (FIL)

As a result of the postulated rupture of the recirculation suction line, the shroud is subjected to asymmetric lateral load towards the break location. This lateral loading is made up of the initial acoustic phase (AC) followed by the steady state flow induced load (FIL). These two phases of the load are mutually exclusive based on the timing of their occurrence. For the purpose of the flaw evaluation, the lateral acoustic and flow induced loads on the shroud were generated at each horizontal weld location. The flow induced loads were generated using TRACG based methodology and applying the various power/flow conditions. It should be noted that since the acoustic loads are higher than AP load at certain weld locations, they were used in the load combination Tesults shown in the Table 2.

5

GENE 0000-0006-2250-04a, Rev. 0 7.7. Fuel Liff Loads (FLL,, FLLd Fuel lift loads (FLL) are imparted on the Core Plate and the Top Guide, which in turn result in vertical upward loads on the shroud at these component locations. The fuel lift loads documented during Reference 7 report evaluation remain bounding, and hence the FLL from the Reference 7 evaluation for the Upset (FLLu) and Faulted (FLLf) conditions are used in this flaw evaluation. The total fuel lift load consists of load from 4 fuel assemblies per guide tube and 185 guide tube assemblies. Further, the total fuel lift load thus calculated at top guide is added to other dynamic loads for welds HI through H4.

Similarly the total fuel lift load thus calculated at the core plate plus the guide tube together are added to the other dynamic loads for welds H5 through H8. All fuel lift loads were generated using time history analysis, and peak time history responses.

8. CALCULATED STRESSES The vertical axial loads resulting in Primary Membrane Stresses (Pm) and the lateral moment loads resulting in Primary Bending (Pb) stresses, are considered in the evaluation at each weld loaction from HI through H7. Table 3 shows the calculated values of Pm and Pb at the horizontal welds for various load combinations.

9. STRUCTURAL MARGIN EVALUATION The structural margin evaluation was conducted using the guidelines provided in Reference 3. A key input in calculating the remaining ligament at a weld, is the assumed crack growth rate during the inspection inierval. The crack growth calculation is described next followed by the summary of the structural evaluation results for the horizontal welds Hl, H2, H3, H4 and H6. Since weld H5 had only minor flaws found and H7 has no flaw found in 1999 inspection, they were simply dispositioned to the end of cycle 10 utilizing the acceptance standard established in Table 2-1 of Reference 3.

GENE 0000-0006-2250-04a,Rev. 0 9.1. Crack Growth Calculation As prescribed in Reference 3 and 8, the crack growth rates used in the length direction was 5x10-5 in/hr and in the depth direction was l.lxl0 5 in/hr under Hydrogen Water Chemistry (HWC) and 2.2x105 in/hr under Nornal Water Chemistry (NWC). In the depth direction, with 90% Hydrogen Water Chemistry (HWC) availability starting April2000, the crack growth rate was calculated based on NWC from May/1999 to March/2000 and HWC from April/2000 onward. The planned length of operation cycle is 24 months. Assuming approximately 90% availability, 24 months translate into approximately 16,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> of hot operation. The assumption regarding 90% availability is based on historic data. Given the conservative nature of the evaluation, the required structural margins are expected to be maintained even with slightly higher than 90%

availability during the next cycle. Only the length direction crack growth is used for areas where through-wall cracking is assumed.

9.2. Evaluation of HI Weld The crack depths at OD and ID were calculated using the guidance provided in Appendix I of Reference 3. All un-inspected regions were conservatively assumed o he cracked through wall. Since the fluence at this weld is calculated to be less than 3x I0'~ at the end of Cycle 10, only limit load evaluation using the computer program DLL [9] was conducted. The details of the structural margin calculation are included in Appendix B and the limiting case margin is shown in Table 4.

9.3. Evaluation of H2 Weld The crack depths at OD and ID were calculated using the guidance provided in Appendix I of Reference 3. All un-inspected regions were conservatively assumed to be cracked through wall. Since the fluence at this weld is calculated to be less than 3x102 0 at the end of Cycle 10, only limit load evaluation using the computer program DLL [9] was 7

GENE 0000-0006-2250-04a, Rev. 0 conducted. The details of the structural margin calculation are included in Appendix C and the limiting case margin is shown in Table 4.

9.4. Evaluation of H3 Weld The crack depths at OD and ID were calculated using the guidance provided in Appendix I of Reference 3. All un-inspected regions were conservatively assumed to be cracked through wall. The fluence level at H3 weld was extrapolated from the fluence distribution at H4 weld reported in Reference 4. As per the guidance provided in ApDendix D (Paragraph D.l.) of Reference 3, through-wall crack depth was assumed in regions where the calculated fluence exceeded 3x 1020 n/cm 2 at the end of Cycle 10. This obviates the need for linear elaslic fracture mechanics evaluation. Therefore, only the limit load evaluation was conducted using the computer program DLL. The details of the structural margin calculation are included in Appendix D and the limiting case margin is shown in Table 4.

9.5. Evaluation of H4 Weld The crack depths at OD (look-up and look-down) and ID (look-up and look-down) were calculated using the guidance provided in Appendix ] of Reference 3. All un-inspected regions were conservatively assumed to be cracked through wall. As per the guidance provided in Appendix D (Paragraph D.].1) of Reference 3, through-wall crack depth was assumed in regions where the calculated fluence exceeded 3x1020 n/CM2 at the end of Cycle 10. This obviates the need for linear elastic fracture mechanics evaluation.

Therefore, only the limit load evaluation was conducted using the computer program DLL. The details of the structural margin calculation are included in Appendix E and the limiting case margin is shown in Table 4.

9.6. Evaluation of H6 Weld The crack depths at OD and ID were calculated using tht guidance provided in Appendix I of Reference 3. All un-inspected regions were conservatively assumed to be cracked through wall. Since the fluence at this weld is calculated to be less than 3x10 20 at the end of Cycle 10, only limit load evaluation using the computer program DLL was conducted.

8

GENE 00000006-2250-04a,Rev. 0 The details of the structural margin calculation are included in Appendix F and the limiting case margin is shown in Table 4.

9.7. Summary of Evaluation Results The calculated values of structural safety factors at the HI, H2, H3, H4 and H6 welds for the limiting operating condition are summarized in Table 4. A comparison with the required values indicates that all of the calculated safety factor values exceed the required values. Based on this it is concluded that the required safety margins at the HI, H2, H3, H4 and H6 welds are maintained in the 'as is' condition to the end of Cycle 10.

However, the reconmended re-inspection interval for the welds that were qualified by plant specific analyses (Hl through H4 and H6) is 6 years to end of cycle 8, taking into account of the uncertainties of possible new crack initiation and crack growth.

SUMMARY

AND CONCLUSIONS The core shroud welds at the LG2 were inspected during the refueling outage at the end of Fuel Cycle 5 (1999). This report documents the results of the structuTal evaluation of the cracked shroud welds to dernonstrate compliance with BWRVIP-76 3]. Specifically, horizontal welds HI, H2, H3, H4 and H6 were evaluated. H5 and H7 were simply dispositioned using guidelines provided in Table 2-1 of Reference 3. The technical evaluations considered the effects of power uprate (PU). It is shown that continued operation in the 'as-is' condition at these welds is technically justified for at least 3 cycles of operation (end of Fuel Cycle 8) assuming normal water chemistry operation until April of 2000, and effective hydrogen water chemistry operation from then on.

Report 0o Rev.O Apd 199A- - -. -.-- -.-. .

GE NuclearEnergy Project Summary From 29 April 1999 through 8 May 1999. General Electric (GE) Inspection Services conducted ultrasonic examinations of Core Shroud Assembly welds at Limerick Generating Station - Unit 2. The scope of the examinations included selected portions of four circumferential welds. H3, H4. H5 and H7. The detection of flaw indications forced an expansion of the work scope to include the examination of acoessible porions of welds HI, 1-2 and H.6.

All welds were examined using the GE OD Tracker scanning device, while employing the conventional technique, which uses 45 shear wave, 60° -longitudinal wave and OD/ID Creeping wave search units in an integral housing. I This report contains specifc details regarding the performance and results of the examinations.

Equipment T

The capabilities of the MicroTomol' data acquisition system, TomoView " Workstation and GE Trimodal search unit were successfully demonstrated in accordance with BWRVIP-03 Reactor Pressure Vessel and internals Guidelines.

MicroTomo n'Acquisition System The MicroTomno data acquisition system was utilized for this examination. The MicroTomotM is a multiplexed, digital system. The system digitizes the entire A-scan or RF waveform at the rate of up to 120 MHz. The entire A-scan Is digitized and archived to a one gigabyte optical disk or 2 gigabyte removable hard disk for off-line analysis and subsequent examination comparisons.

OD rackerScanner This device rests upon and drives around the steam dam structure of the core shroud assembly.

Interchangeable vertical arms of appropriate length descend from the carriage of the GE OD Tracker to the elevation of each of the four welds examined. The search units are applied to the outside surface of the shoud and are manipulated about the accessible portions of the circumference of the shroud. Search units are also moved toward and away from each weld, in a raster scan pattern. ThTis scanning motion generally provides 'ull coverage of the BWRVIP-specified surface regions on both sides of fle weld.
