I. 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, (L2R1 1) March 17, 2007, through the end of the current refuel outage (L2R12). This refuel outage was the twelfth for LaSalle County Station Unit 2. It started January 19, 2009 and ended February 10, 2009. This refueling outage was the first 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 2. 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 2, Period 1 (October 1, 2007 through September 30, 2010)

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

Unit 2, 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 Nondestructive 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.

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.
