Murley (NRC), "Structural Margin Evaluation for Reactor Pressure Vessel Head Studs," dated October 3, 1991 Enclosed is the Exelon Generation Company, LLC (EGC) LaSalle County Station Unit 2 Post-Outage 90-Day (ISI) Summary Report, submitted in accordance with 10 CFR 50.55a, "Codes and Standards," and the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section Xl, Article IWA-6200, Paragraph IWA-6230.

The enclosed Post-Outage 90-Day ISI Summary Report is for examinations, repair/replacement activities, and Containment Inservice Inspection (CISI) performed between the end of LaSalle County Station Unit 2 ninth refueling outage on February 21, 2003, through the end of the current, tenth refueling outage. This refueling outage started February 7, 2005, and ended March 16, 2005. This refueling outage was the first scheduled for the Third Inspection Period of the Second Inspection Interval, effective from July 5, 2004, through July 4, 2007, for LaSalle County Station Unit 2.

Pressure boundary leakage was detected during examination of the reactor coolant pressure boundary. The leakage was reactor coolant from the weld joint between the body of valve 2B21-F028D and drain line 2MS20AD-2". Issue Report # 311917 was generated to document the leak. Work Order # 789955 was generated and a ASME Section Xl Repair Plan was used to remove the entire defective weld and re-weld the connection. The repaired connection was subjected to System Leakage Test pressure and no leakage was detected. The components' materials of.

construction being joined by the repair weld necessitated Post Weld Heat Treatment (PWHT) of the completed weld. To monitor PWHT, five temporary thermocouples were tack welded to the valve body and one thermocouple was tack welded to the drain line pipe. The PWHT of the completed repair weld was successful and the temporary attachments and their tack welds were removed from the components.

D447

June 10, 2005 U.S. Nuclear Regulatory Commission Page 2 The weld removal areas on the valve body and the drain pipe were not examined by the Magnetic Particle (MT) or Liquid Penetrant (PT) methods as required by Sub Subparagraph NB-4231.2 (g) of the ASME Boiler and Pressure Vessel Code Section III, 1974 Edition. This ASME Code non-compliance was discovered following start-up from the refueling outage. Issue Report # 314183 was generated to document the ASME Code non-compliance. Operability Evaluation # 05-002 was completed and determined that the valve and drain line would remain operable until the weld removal areas could be examined using MT or PT methods. Action Tracking Item # 314183-03 was created to track the completion of the required examinations.

Attachment Post-Outage 90-Day ISI Summary Report INTRODUCTION The Inservice Inspection (ISI) Summary Report addresses examinations, repair/replacement activities, and Containment Inservice Inspections (CISI) performed between the end of the previous refuel outage, (L2R09) February 21, 2003, through the end of the current refuel outage (L2R1 0). This refuel outage was the tenth for LaSalle County Station Unit 2. It started February 7, 2005 and ended March 16, 2005. This refuel outage was the first scheduled for the Third Inspection Period of the Second Inspection Interval, effective from October 17,1994, through July 4, 2007, for LaSalle County Station Unit 2. Paragraph IWA-2430 (e) of the American Society of Mechanical Engineers (ASME) Code Section Xi allows an Inspection Interval to be extended for a period of time equivalent to the duration of a continuous outage that exceeds six months.

The Second Inservice Inspection Interval is divided into three successive inspection periods as determined by calendar years of plant service within the inspection interval.

Identified below are the period dates for the Second Inservice Inspection Interval as defined by Inspection Program B. In accordance with IWB-2412 (b), the Inspection Periods specified below may be decreased or extended by as much as one year to enable inspections to coincide with.LaSalle County Station's refuel outages.

Unit 2, Period 1 (October 17, 1994 through July 4, 2000**)

Unit 2, Period 2 (July 5, 2000 through July 4, 2004)

Unit 2, Period 3 (July 5, 2004 through July 4, 2007)

• • This date reflects a 932-day extension allowed by IWA-2430 (e) for L2R07.

Augmented Inservice Inspection (AISI) examinations, ISI and CISI, and Preservice Inspections (PSI) were completed prior to and during the refuel outage as required by the Code of Federal Regulations, Technical Requirements Manual, ASME Boiler and Pressure Vessel Code, Section Xi, 1989/1998 Edition, and the applicable requirements of the Performance Demonstration Initiative (PDI).

Personnel from General Electric Nuclear Energy (GENE) Inspection Services and Exelon Nondestructive Examination Services group (NDES) performed the Non-Destructive Examinations (NDE), Magnetic Particle (MT), Liquid Dye Penetrant (PT),

and manual and/or automated Ultrasonic (UT) techniques that were used during these inspections. All Intergranular Stress Corrosion Cracking (IGSCC) examinations were completed by personnel qualified for the detection and discrimination of IGSCC Cracking in accordance with the PDI. NDES provided necessary resolution of technical problems, reviewed all ISI personnel qualifications, and all visual, surface, and volumetric examination results.

1

Visual examinations of reactor vessel internals, component supports, and piping pressure tests were performed by GENE personnel, Exelon Generation Company, LLC (EGC) employees of the LaSalle County Station Programs Engineering Group and NDES personnel. These individuals were appropriately certified as ASME Code Section Xl Visual Examiners to EGC's written practice. An underwater camera was used for the visual inspection of the reactor vessel internals. The camera was proven capable of resolving 0.001" and 0.0005" stainless steel wires while underwater and, in the same lighting conditions found during the actual inspection.

The services of an Authorized Nuclear Inservice Concrete Inspector (ANIC) were provided by Hartford Steam Boiler Inspection & Insurance Co. of Connecticut, 2443 Warrenville Road, Suite 500, Lisle, IL 60532.

Mr. Rocky W. White, ANIC, State of Illinois #1927, reviewed written Nondestructive Examination procedures, personnel qualifications, instrument and material certifications, ASME Code Section Xl examination results, Owner's Reports of Repair or Replacement (Form NIS-2), and the Owner's Data Report for Inservice Inspection (Form NIS-1).

II.

SCOPE OF INSPECTIONS The ISI Summary Report is provided with tables that consolidate the extent and results of inspections performed between the end of the previous refuel outage (L2R09),

February 21, 2003, through the end of the current refuel outage (L2R1 0). An explanation of all abbreviations used is in Attachment 3 of the Summary Report.

Table A provides a listing of all completed ASME Code Section XI examinations for this refuel outage with the exception of component support examinations and pressure testing which are addressed separately. Table A is divided by ASME Code Category with a description of the items examined, including the examination types, and the examination results.

Table B provides a listing of all AISI. These are not ASME Code Section Xl requirements, but are additional examination area requirements, increased frequency requirements, or combinations of these, which are requested by the Nuclear Regulatory Commission (NRC). Others have been deemed prudent in view of EGC and industry experience. Table B also gives a description of the items examined as well as the examination types, and examination results. Table B includes the following categories:

BWRVIP These examinations are of austenitic stainless steel piping for the detection of IGSCC.

REACTOR VESSEL INTERNALS AISI - These examinations include inspection of reactor internal components required by the NRC such as core spray spargers and piping. These have been adopted by EGC through its commitment to the Boiling Water Reactor Vessel and Intemals Project (BWRVIP). Other examinations, such as the steam dryer and steam separator, were deemed prudent from industry experience.

MISCELLANEOUS AISI -

Pursuant to LaSalle County Station's commitment to the NRC (reference letter), the AISI examinations included an augmented "End-Shot" UT examination of 100% (76 total) of the reactor pressure vessel closure studs. The "End Shot" UT examination was completed using procedures, calibration standards, and personnel which met all applicable requirements of the 1989 Edition of ASME Code Section Xl, and the PDI.

2

Table C provides a listing of all completed ASME Code Section Xl Class I and 2 component support examinations for this outage. Table C gives the support #(s),

examination type, and examination results. Table C is divided by ASME Code Class.

Table D provides a listing of pressure testing of ASME Code Section Xl Class I & 2 piping and components completed during the period between the L2R09 and L2R10 refuel outages. As applicable, Code Case N-498-4, "Alternative Rules for 10-Year Hydrostatic Testing for Class 1, 2, and 3 Systems Section Xl, Division 1," is utilized during the Third Inspection Period. ASME Code Class 1 components and piping were examined using the VT-2 method during the system leakage test conducted at 1035 psig prior to reactor start-up, within the nominal operating pressure range of the reactor pressure vessel associated with 100% rated reactor power. Pressure testing will be ongoing throughout the remainder of the Third Inspection Period.

Table E is a listing of ASME Code Section Xl Class 1 and 2 repair/replacements completed since the previous refuel outage and those completed during the tenth refuel outage of Unit 2, in accordance with ASME Code Section Xl, Articles IWA-4000 and IWA-7000. This includes the Work Order # which served to implement the applicable activity and a short description. The documentation packages are on file at LaSalle County Station. Each activity has been certified on the Owner's Report of Repair or Replacement, which will serve as documentation of these repair/replacements.

The name of each major component or appurtenance inspected during the tenth refuel outage is listed on Form NIS-1 (Attachment 1) in column #1. This includes the reactor pressure vessel and the Class 1 piping system. A detailed list of components or appurtenances inspected appears in the abstracts listed as items 13, 14, and 15 on Form NIS-1. The descriptions including size, capacity, material, location, and drawings to aid in identification of the components or appurtenances have been previously submitted, including the N-5 ASME Code Data Reports and the Second 10-Year ISI Plan. This information was not included in the ISI Summary Report. These documents are on file at LaSalle County Station. This also applies to the PSI and ISI Summary Reports.

Ill.

SUMMARY

OF RESULTS AND CORRECTIVE ACTIONS The ASME Code Section Xl ISI results obtained during this refuel outage were compared with the Preservice and Inservice results. The following is a summary of the results and corrective actions taken.'

1.

ASME Code Section Xl Components Recordable indications were detected in ASME Code Section Xl components and other non-code components, during augmented examinations as discussed below or in the applicable Tables. All indications detected in ASME Code Section Xl components were evaluated against the applicable acceptance standards.

Examinations and tests of the Unit 2 ASME Code Section Xl Class CC post tensioning system were performed. The following conditions have been identified and are being reported as required by 10 CFR 50.55(a):

3

During the examination of tendons, free water was identified in either the grease can or anchorage of the following tendons:

Shop End H39GF 1.5 Ounce Field End H72F 1 Ounce The difference between the amount of sheeting filler grease removed and the amount replaced exceeded 10% of the tendon net duct volume in the following tendons:

V201A 20.29%

V201A 14.88%

V204A 10.82%

V205A 15.45%

V214A 10.77%

V216A 14.04%

V218A 21.06%

V221A 13.09%

V225A 11.50%

V228A 12.20%

V229A 13.93%

V247C 38.67%

Examination of tendons identified degradation in the form of broken wires found on the following:

V219A 1 of 90 wires broken V228A 3 of 90 wires broken. This tendon was replaced.

V229A 9 of 90 wires broken. This tendon was replaced.

V247C 2 of 90 wires broken Five "A" tendons and all thirty "B" tendons are inaccessible for examination during power operations. Degradation of the tendons is due to water-induced corrosion by failure of the water intrusion barriers and, aided by a loss of the corrosion protection medium (grease) in the top region of the accessible "A" tendons. The design of the inaccessible tendons incorporates a welded cover that prevents this type of degradation. To confirm this conclusion, a corrective action has been generated to inspect one inaccessible "A" and "B" tendon at the next scheduled refueling outage. Action Tracking Item #157920, Assignment 33, tracks this inspection.

2.

RH40-2877X Welded Attachments During Magnetic Particle testing of the welded attachment lugs associated with component support RH40-2877X, two linear indications were detected. The linear indications were located in the pipe base metal near the lug weldment. The indications were compared to the acceptance standards of ASME Section Xl, WB-3514-4 and did not meet the acceptance standards. Issue Report #300094 was generated to disposition the indications. ASME Section Xl, IWC-3512.1(c), allows flaws exceeding the standards of IWB-3514-4 to be examined by the volumetric method and compared to applicable standards for the volumetric method (i.e., Table IWB-3514-1). Alternatively, controlled mechanical removal may be used to establish each indication's depth. This is supported by ASME Code Interpretation XI-1-95-42, which allows a controlled mechanical removal technique (e.g., grinding) to be used to establish if the surface indication would have been acceptable to the volumetric acceptance standards of IWB-3500 or IWC-3500.

Work Order #781039 was generated and a Section Xl Repair Plan was used to implement controlled mechanical flaw removal using localized grinding. Ultrasonic thickness measurements were performed prior to grinding and after the indications were completely removed. The deepest measurement along each indication was recorded after each of the indications was completely removed. The amount of metal removed representing the initial depth of each indication was used to compare to the acceptance 4

standards of IWB-3514-1. Both indications were acceptable to the volumetric standards and no sample expansion was performed.

3.

Pressure Boundary Leakage of Pipe Line 2MS20AD Pressure boundary leakage was detected during examination of the Reactor Coolant Pressure Boundary completed with the System Leakage Test. The leakage was reactor coolant from the weld joint between the body of valve 2B21 -F028D and drain line 2MS20AD-2". Issue Report # 311917 was generated to document the leak. Work Order

1. 789955 was generated and a ASME Section Xl Repair Plan was used to remove the entire defective weld and re-weld the connection. The repaired connection was subjected to System Leakage Test pressure and no leakage was detected. The materials of construction of the components being joined by the repair weld necessitated PWHT of the completed weld. To monitor PWHT, five temporary thermocouples were tack welded to the valve body and one thermocouple was tack welded to the drain line pipe. The PWHT of the completed repair weld was successful and the temporary attachments and their tack welds were removed from the components. The weld removal areas on the valve body and the drain pipe were not examined by the MT or PT methods as required by Sub Subparagraph NB-4231.2 (g) of the ASME Boiler and Pressure Vessel Code Section 111, 1974 Edition. This ASME Code non-compliance was discovered after start-up from the refueling outage. Issue Report # 314183 was generated to document the ASME Code non-compliance. Operability Evaluation # 05-002 was completed and determined that the valve and drain line remain operable until the weld removal areas can be examined using MT or PT methods. Action Tracking Item # 314183-03 was created to track the completion of the required examinations.

4.

Steam Dryer An augmented visual examination of the steam dryer is completed during each refuel outage. The steam dryer contains numerous indications that were recorded during previous examinations. Areas where historically indications were identified include the lifting eye bracket welds, upper dryer bank vertical welds, uppers support ring, drain channel welds, and dryer bank panels. Specific inspections as recommended by SIL 644 Revision 1 were performed and new indications were identified on tie bars 5 and 28, and on the upper strap associated with the lifting lug at 2150. The indications on the tie bars were evaluated as acceptable as-is with no repair required in accordance with EC

1. 354310. The broken upper strap on the 2150 lifting lug was removed under EC

1. 353949. Issue Reports #308912 and #309163 (tie bar indications) and #301422 (broken upper strap) were generated to document these conditions. These examination results have been documented on the GENE examination data sheets.

5.

Steam Separator An augmented visual examination of the steam separator is completed during each refuel outage. No new indications were observed. The welds and separators around a steam separator tie bar removed in L2R09 were examined as recommended in the removal design change, and no indications were observed. These examination results have been documented on the GENE examination data sheets.

6.

Shroud Head Bolts All shroud head bolts were examined, and pin wear was identified on three bolts and window wear was observed on one of these same bolts. Issue Report #309413 was generated to document these indications. The indications were accepted as-is under design analysis EC 354310.

7.

Jet Pumps One hundred percent (20 total) of the jet pump inlet mixers were replaced with new inlet mixers that had labyrinth seals machined in the slip joint area, with oversized non-stellite main wedges. The changes in the inlet mixer were performed in accordance with EC 348413. The existing 10 Auxiliary Wedges previously installed to eliminate gaps between the jet pumps and the inlet mixers were removed. Visual examinations performed after inlet mixer replacement revealed that no Auxiliary Wedges were required. During the inlet mixer replacements, 17 of the 20 hold down beams were proactively replaced.

Examinations of areas made accessible below the core plate were performed when the inlet mixers were removed. Examinations included accessible portions of bottom head cladding in the vicinity of the jet pumps, surfaces/welds on Control Rod Drive (CRD) stub tubes and guide tubes, shroud to Reactor Pressure Vessel (RPV) weld H9 located below the shroud support plate, and a general overview of the bottom head. No recordable indications were noted. These examination results have been documented on the GENE examination data sheets.

8.

Core Spray Piping An augmented ultrasonic examination was completed on accessible core spray piping welds internal to the reactor vessel. An existing relevant indication on weld BP5 was re-sized with no noted growth after two cycles of operation. Issue Report #300599 was generated to document this indication. The indication was accepted as-is for two additional cycles under design analysis L-002704.

9.

Core Shroud Four of the core shroud horizontal welds were ultrasonically examined in accordance with BWRVIP-76, UBWR Vessel and Internals Project, BWR Core Shroud Inspection and Flaw Evaluation Guidelines". - No relevant indications were identified. Figure 2-2 of BWRVIP-76 requires that the inspected length for each weld be greater than 50% of the length of the weld or a plant specific evaluation is performed in accordance with Appendix D of BWRVIP-76. The length of weld examined was as follows:

H3: Looking-up:

73.1%

H3: Looking-down:

0%

H5: Looking-up:

40.5%

H5: Looking-down:

71.0%

H6: Looking-up:

0%

H6: Looking-down:

74.5%

H8: Looking-up:

73.7%

H8: Looking-down:

0%

Greater than 50% coverage was not achieved on both sides of any of these welds, and a plant specific evaluation was required per Section 2.2 of BWRVIP-76 and is documented in calculation L-003119. The calculation concluded that the Unit 2 core shroud has been very conservatively evaluated in accordance with BWRVIP-76 to maintain structural integrity for a minimum of 2 years, until the eleventh fuel cycle.

Note: LaSalle County Station weld nomenclature differs from the BWRVIP. The shroud contains two beltline welds (H4 and H5), H6 is BWRVIP weld H5, and H8 is BWRVIP weld H7.

ASME Code Section Xl Piping & Component Support Examinations Piping and component supports were inspected (42 total) during this refuel outage. These were distributed between ASME Code Section XI Class 1 and 2/D+ supports as follows:

ASME Code Class 1 - 22 supports.

• ASME Code Class 2/D+ - 20 supports.

One rejectable indication was detected during these examinations.

MS01-2005V had spring can settings outside of design tolerances. Issue Report #

305584 was initiated to disposition the indication. The condition was evaluated under Engineering Change # 354132 and found to be acceptable.

As required by ASME Section XI Code Case N-491-1, "Alternative Rules for Examination of Class 1, 2, 3, and MC Components Supports of Light-Water Cooled Power Plants Section Xl, Division 1," sample expansion examinations were completed for the rejectable indication. No further detrimental indications were detected.
