BYRON STATION UNIT 2 REFUELING OUTAGE 15INSERVICE INSPECTION REPORT

1.1.0 INTRODUCTION

Inservice inspections of American Society of Mechanical Engineers (ASME) Class 1,2, 3, CC, and MC components were conducted at Byron Station Unit 2 from October24, 2008 through May 8, 2010. The majority of these inspections were performedduring the fifteenth refueling outage (B2R15) from April 19 through May 8, 2010.

B2R1 5 is the first outage of the Second Period in the Third Inspection Interval.

The examinations were performed in compliance with the rules and regulations ofASME Section Xl 2001 Edition, through the 2003 Addenda, pursuant to therequirements of 10 CFR 50.55a.

See 1.7.0 of the introduction for a listing of referenced documents.

This summary report meets the requirements of ASME Code, IWA-6000 for theinspection of Class 1 and 2 components and piping. Class CC and MC componentsin the Containment Inservice Inspection (CISI) program are included whenexamination results require reporting as specified in 10 CFR 50.55a.

The Nondestructive Examination (NDE) Inservice Inspection (ISI) Program Plan forClass 1, 2, 3, CC, and MC components was developed in accordance with therequirements and intent of Section Xl Subsections IWA, IWB, IWC, IWD, IWE, IWFand IWL, 2001 Edition, through the 2003 Addenda.

In addition to the ASME Section Xl requirements of examination, certain NuclearRegulatory Commission (NRC) augmented ISI inspections and industry initiatives(NEI-03-08) were required. The Byron Station Unit 2 augmented ISI examinationrequirements include:

6 Class 1 pressure boundary examinations for leakage at nominal operatingpressure, in accordance with NRC Generic Letter 88-05;

* Class 1 Alloy 600 weld examinations in accordance with MRP-139, N-722, andN-729-1;

6 Class 2 and 3 pressure boundary examinations for leakage at nominal operatingpressure, in accordance with NUREG 0737.

* Examination of RCP Flywheels in accordance with Regulatory Guide 1.14.

* Class 1 examinations of non-isolable Reactor Coolant System branch lines forThermal Fatigue in accordance with MRP-146;

Specific requests for relief were developed and submitted for the NRC's reviewwhen the code and/or augmented requirement(s) were deemed to be impractical,results in excessive hardship, or an alternative examination method is determinedas more suitable for the particular component.

Section 1.0 Page 1 of 6


1.1.1 Identification of Examination Requirements

The Section 7.0 of the ISI Program Plan contains the examination program tables.These tables are consistent with the tables found in Subsections IWB, IWC, IWD,IWE, IWF, and IWL-2500 of the ASME Code. The examination tables include thecorresponding code category, item number, and component/weld selection inconformance with examination requirements and intent of Section Xl.

For Class 1, 2, and certain non-class piping components, the requirements of RiskInformed Inservice Inspection (RI-ISI) are followed using EPRI TRI 12657 and Table1 of ASME Code Case N-578-1.

1.1.2 Identification of Exempted Components

ASME Class 1, 2, and 3 components, or parts of components, that are not includedin the examination tables and that are exempt from examination, as specified inSection Xl Paragraphs IWB, IWC, and IWD-1200, and Tables IWB-2500-1, IWC-2500-1, and IWD-2500-1, are identified in the NDE Program Plan in conjunction withtechnical justification(s) for exempting the component/system.

Class 1 or 2 piping welds exempted by IWB and IWC-1200 are not included in theRI-ISI program. Previous selection and examination exemptions identified in TablesIWB and IWC-2500-1 for Examination Categories B-F, B-J, C-F-i, and C-F-2, arenot allowed under the requirements of the RI-ISI program. With the adoption of RI-ISI, welds evaluated as Risk Category 6 or 7 are not subject to examination.

1.1.3 Implementation of the ISI Program

Exelon Nuclear, or its designee, examined ASME components utilizing the followingmethods: MT, PT, UT, VT-1, VT-2, and VT-3. The components examined complywith the ISI Program Schedule, Byron Station Technical Specifications, and/orcomply with the ASME Section Xl Repair/Replacement Program.

Personnel certified in nondestructive examination are qualified in accordance withANSI/ASNT CP-1 89, 1995 Edition and ASME Section Xl, 2001 Edition through 2003Addenda including December 2003 Erratum.

All personnel performing ASME Section Xl ultrasonic examinations are qualified tothe requirements of ASME Section Xl Appendix VII.

The NDE procedures were developed and qualified in-conformance with ASMESection V and XI as applicable.

All ISI NDE, including evaluation of flaw indications, were performed in accordancewith the requirements stipulated under Section XI IWA-2200. For componentsincorporated into the RI-ISI program, the guidance for the examination volume for agiven degradation mechanism is provided by the EPRI Topical Report while theguidance for the examination method is provided by Code Case N-578-1.



1.1.4 Siginificant Activities During B2R15

During the refueling outage, the Alloy 600 welds were examined for PWSCC per therequirements specified in N-722:

" All reactor vessel bottom-mounted instrument penetrations were visuallyexamined for leakage Item 115.80 weldments.

" All reactor vessel hot leg safe-end welds were visually examined for leakage forItem B15.90 weldments.

" One Alloy 600 reactor vessel cold leg safe-end weld was visually examined forleakage for Item B15.95 weldments.

" The steam generator primary channel head drains were visually examined forleakage for Item B15.120 weldments.

The reactor vessel head exterior surface was visually examined for evidence ofleakage per the requirements specified in N-729-1 Note (4) for Item B4.1 0components. One repaired reactor head penetration was examined with surfaceand volumetric methods per Item B4.20 and the approved relief request 13R-16.

All weld overlays on the pressurizer safe-end welds were volumetrically examined.This examination complies with the requirements specified in MRP-139 for CategoryF welds and ASME Appendix Q Paragraph Q-4300(a). Use of Appendix Q wasaddressed in relief request 13R-08.

1.1.5 ASME Section Xl Code Cases

N-566-2 is incorporated into the current Byron Station ISI Program and was utilizedduring this fuel cycle.

The implementation of the risk-informed program as described in relief request 13R-02 utilized N-578-1 during this Inspection Interval.

For Repair/Replacement activities, code cases are identified on the applicable FormNIS-2.

1.1.6 Witness and Verification of Examination

The inservice inspections were witnessed and/or verified by Authorized NuclearInservice Inspectors (ANII) associated with Hartford Steam Boiler CT of Hartford,Connecticut, Chicago Branch, at 2443 Warrenville Rd., Suite 500, Lisle, Illinois60532.

1.1.7 Corrective Measures

A surface examination revealed two indications located in the fusion zone betweentwo weld beads of an attachment weld on the 12" SI pipe to the flued headPenetration P-66 closure. The weld is identified in the Inservice Inspection Programas 2SI04B-1 2/C02 and was examined as Observation 15-203 in the outage. The



weld was selected under ASME Section Xl Class 2 Examination Category C-C; ItemC3.20. The indications were described in Issue Report 01057786 and OE 31183.

The indications were near the weld toe on the flued head side of the fillet weld. Theindications followed the interface between the beads while being removed and werethus classified as lack of fusion. The areas of the indications were blended and theindications were completely removed.

Additional examinations were performed on other attachment welds of similarmaterials and service per the requirements of ASME XI IWC-2430. Welds2RH01 BA-1 2/C03 and 2SI05BA-8/C02 were examined as Observations 15-223 and15-221 respectively. The additional examinations were acceptable and no othercode related actions are required.

This was a new valve which had not been installed at site.Repair. The valve was repaired under the NWS VR/NR programs. The X750 disc waslapped and oxidized disc prior to reuse. The nozzle seat was passivated after lapping.The spring was load tested with satisfactory results. Wear areas were cleaned asnecessary. All wear areas and contact points were lubricated prior to assembly.Initial Test* The valve was allowed to thermally stabilize at a holding pressure of -1000psig. A total of four lifts were done. No adjustments were required. The final two liftswere within the required as-left BYRON acceptance range of +1% of set-pressure.Final Seat Tightness Testing: Following set-pressure certification, system pressurewas maintained at 90%. No moisture was detected on a cold bar placed in the vicinityof the seats.All work was done by NWS personnel. An NWS test supervisor was present during alltesting. An HSB of CT reviewed documentation, witnessed nameplate installation, andcompleted an NVR-1 form.The valve was cleaned, sealed and packaged for return shipment.

Job SummaryAs-found testing had been done at site.Repair: The valve was repaired under the NWS VR/NR programs. The X750 disc waslapped and oxidized disc prior to reuse. The nozzle seat was passivated after lapping.The spring was load tested with satisfactory results. Wear areas were cleaned asnecessary. All wear areas and contact points were lubricated prior to assembly.Initial Test: The valve was allowed to thermally stabilize at a holding pressure of -1000psig. A total of three lifts were done. No adjustments were required. The final two liftswere within the required as-left BYRON acceptance range of +1% of set-pressure.Final Seat Tightness Testing: Following set-pressure certification, system pressurewas maintained at 90%. No moisture was detected on a cold bar placed in the vicinityof the seats.All work was done by NWS personnel. An NWS test supervisor was present during alltesting. An HSB of CT reviewed documentation, witnessed steam certification testing,nameplate installation, and completed an NVR-1 form.The valve was cleaned, sealed and packaged for return shipment.
