1. 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, (L1 R12) February 28, 2008, through the end of the current refuel outage (L1 R13). This refuel outage was the thirteenth for LaSalle County Station Unit 1. It started February 8, 2010 and ended March 6, 2010.

This refueling outage was the second outage scheduled for the First Inspection Period of the Third Inservice Inspection Interval, and the Second Containment Inservice Inspection Interval, effective from October 1, 2007, through September 30, 2010, for LaSalle County Station Unit 1. The Third Inservice Inspection Interval, and the Second Containment Inservice Inspection Interval are 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 inspection intervals as defined by Inspection Program B. In accordance with IWA-2430 (d)(3), 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 1, Period 1 (October 1, 2007 through September 30, 2010)

Unit 1, Period 2 (October 1, 2010 through September 30, 2014)

Unit 1, Period 3 (October 1, 2014 through September 30, 2017)

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, 2001 Edition through the 2003 Addenda, and the applicable requirements of the Performance Demonstration Initiative (PDI).

Personnel from General Electric Hitachi Nuclear Inspection Services and Exelon Nondestructive Examination Services (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 General Electric Hitachi Nuclear Inspection Services 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 XI 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 and .044" characters 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 certifications, material certifications and ASME Code Section XI examination results. Owner's Reports of Repair or Replacement (Form NIS-2), and the Owner's Data Report for Inservice Inspection (Form NIS-1) were certified by Mr. Mark Bosnich, ANII, State of Illinois #2144.

U. 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 (L1 R12),

February 28, 2008, through the end of the refuel outage (L1 R13). 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, the examination results and where applicable, the percentage of examinations completed.

Table B provides a listing of all AISI. These are not ASME Code Section XI requirements, but are additional examination area requirements, increased frequency requirements, or combinations of these requirements, which are requested by the Nuclear Regulatory Commission (NRC). These other requirements 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 and other susceptible materials 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 Internals Project (BWRVIP). Other examinations, such as the steam dryer and steam separator, were deemed prudent based on 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% (68 total) of the reactor pressure vessel closure studs. The "End Shot" UT examination was completed using procedures, calibration standards, and 2

personnel that met all applicable requirements of the ASME Code,Section XI, 2001 Edition through the 2003 Addenda, and the PDI.

Table C provides a listing of all completed ASME Code Section XI Class 1 and 2 component support examinations for this outage. Table C gives the support number, examination type, and examination results. ASME Code Class divides Table C.

Table D provides a listing of pressure testing of ASME Code Section XI Class 1 and 2 piping and components completed during the period between the L1 R12 and L1 R13 refuel outages. ASME Code Class 1 components and piping were examined using the VT-2 method during the system leakage test conducted at 1042 psig prior to reactor start-up, which is 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 First Inspection Period.

Table E is a listing of ASME Code Section XI Class 1 and 2 repair/replacements completed since the previous refuel outage and those completed during the twelfth refuel outage of Unit 1, which are in accordance with ASME Code Section XI, Articles IWA-4000. These include the work order number that 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 thirteenth refuel outage is listed in column # 1 on Form NIS-1 (Attachment 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. 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.
