This refueling Outage was the first outage scheduled for the Third Inspection Period of the Third ISI Interval, and the first outage scheduled for the Second Containment 1SI Interval', effective from October 1 2014, through September 30, 2017, for LaSalle County Station Unit2.

The Third Inservice Inspection Intervalapd the Second Containmernt 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 periodidates 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 refueling 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 Infservice Inspection (AISI) examinations, ISI and CISl, and Preservice Inspections (PSI) were completed prior to and during the refueling outage as required by the Code, ofFederal Regulations,' Technicial Requirements Manual, ASME Boiler and Pressure Vessel Code, Section XI, 2001 Edition through the 2003 Addenda, and the applicable requirements of the Perf ormance Demonstration Initiative (PDI).

Personnel from General Electric Hitachi Nuclear Inspection Services and Exelon Nondestructive Examination Services (NOES) performed the Non-Destructive Examinations. (NDE), Magnetic Particle'.(MT), Liquid Dye Penetrant (PT), and manual Ultrasonic (UT) techniques'that were used during these inspections.

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 perso66nel. 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 0.044" 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 The Hartford Steam Boiler Inspection and Insurance Company of Connecticut, 2443 Warrenville Road, Suite 500, Lisle,- IL60532.

Mr. Adam M.Prine, ANIi, State of Illinois.#2146 IC,,reviewed written Nondestructive Examination procedures, personnel qualifications, instrument certifications, material certifications and ASME COde Section XA examination results. Mr. Prine also certified 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 provides tables that consolidate the extent and results of inspections performed between the end of. the previous refueling outage (L2R14), March 4, 2013, through the most recent refueling..outage (L2R1 5). 'An explanation'of all abbreviations provided is in Attachment 3,of the Summary Report. A listing of Code Cases applicable to the activities described in this report is contained in-the Third 10-Year Inspection Interval ISI Plan document on file at LaSalle County Station.

Table A provides a listing ofall completed ASME Code, Section XI examinations for this refueling 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 C0ode Section AI 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 2

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.4), the AISI examinations includedoan 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 that met all applicable requirements of the ASME Code, Section Xl, 2001 Edition through the 2003 Addenda, and the PDL

ý.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 providesa listing of pressure testing of ASME Code Section XI Class 1 and 2 piping and components completed during the period between the L2R14 and L2R15 refueling outages. ASME.Code Class 1 components and piping were examined using the VT-2 method during the system leakage test conducted at 1037 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 Third Inspection Period.

Table E is a listing of ASME Code Section Xl Class .1ýand 2. repair/replacements completed since the previous refueling outage and those completed during the fifteenth refueling outage of Unit.2, which are in accordance with ASME Code Section XI, Article IWA-4000. These include the work order number, 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 Repairor Replacement, which will serve as documentation of these repair/replacements.

The name of each major component or appurtenance. inspected during the fifteenth refueling outage:is listed in column # 1 on Form NIS-I (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 15on Form NIS-I. 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.
