Subject:

Submittal of the In-Service Inspection (ISI) Owner's Activity Report (OAR.for the 20th Refueling Outage for Unit 2 and Supplement to the 18Refueling Outage OAR for Unit 3Enclosed in Attachment 1 is the ISI Owner's Activity Report covering ISI activities associated with the second period of the current ISI inspection interval for Unit 2. Thisreport is submitted pursuant to the American Society of Mechanical Engineers (ASME)Boiler and Pressure Vessel Code,Section XI, "Rules for the Inservice Inspection ofNuclear Power Plant Components,"

Article IWA-6200, "Requirements" (2001 Editionthrough 2003 Addenda) and ASME Code Case N-532-4 (Repair/Replacement ActivityDocumentation Requirements and In-Service Summary Report Preparation andSubmission, section Xl, Division 1).In addition, a supplement to the flaw evaluation for the Unit 3 18 ' Refueling OutageOAR concerning a closure head weld is being provided in Attachment

2. This indication was originally discovered during the 13th Unit 3 Refueling Outage (3rd ISI inspection interval) and was re-inspected satisfactorily in the 18' Unit 3 Refueling Outage in 2011(4th ISI inspection interval).

A summary of the evaluation performed for this closure headindication is provided in Attachment 2.If you have any questions or require additional information, feel free to contact BrianRufo at 717-456-3250.

-Supplement to Unit 3 Owner's ActivityReportDuring review of historical data, it was identified that the Unit 3 closure head weld, CH-MA, examined in P3R18 had been evaluated using the methods and acceptance criteriaof the 1989 edition of the ASME Section XI code (3rd ISI Inspection Interval code). Thisevaluation should have used the 2001 edition of the ASME Section Xl code since theevaluation was performed in the 4th SI Inspection Interval.

This is a self-identified issuethat was captured in the PBAPS Corrective Action Program (IR 1554519).

A codereconciliation was performed to ensure that the identified weld flaw was still acceptable in accordance with the ASME Section Xl 2001 edition.

The reconciliation performed determined that the flaw evaluation met the requirements of the 2001 code with nochanges required.

The indication was originally discovered during the 13th Unit 3Refueling Outage (3rd ISI inspection interval) and was re-inspected satisfactorily in the18't Unit 3 Refueling Outage in 2011 (4th ISI inspection interval).
