Background -Part 54 Safety Application ApproachLessons learned from previous Exelon and industry license renewal projects are utilized in the PBAPS SLRA ProjectExelon has extensive aging management experience22 of 23 units have renewed operating licenses13 units are operating in the PEOExelon has held leadership positions and participates in NEI and EPRI initiatives that prepared the industry for Subsequent License Renewal & Long Term OperationsExelon participated through NEI in providing comments to the staff on GALL/SRP -SLRCurrent NRC Expectations and SRP GuidanceExelon reviewed RAIs that have been issued to recent license renewal applicants to ensure consistency with current NRC expectations and SRP guidanceIncludes lessons learned from River Bend acceptance review 5

Part 54 Safety Application ApproachSafety portion format is based on NUREG -2192 (SRP-SLR), NEI 17-01, and Reg. Guide 1.188 (pending)Comprehensive Scoping & Screening was performedAging Management ReviewsHighly consistent : >

98% A through E notes (approx. 6400 line items)No new aging effects since first license renewalAging Management ProgramsGoal is to maximize consistency with GALL-SLR Includes Aging Management Effectiveness Review of First LR programsTLAAsAddressed First License Renewal TLAAs Extensive review for additional TLAAsReview of SLRA Internal consistency checks being performed (e.g., enhancements, aging effects)Industry Peer review will be performed 6

GALL-SLR Consistency and Commitments 7

Discussion Topics/Lessons LearnedGAP Analysis for Reactor Internals: Section 3.1.2.2.12 for BWR InternalsBases for projecting neutron fluence values for RPV and RVI to the end of a proposed subsequent period of extended operationAre there changes in methods of analysis since first license renewal?RPV Fluence Methodology consistent with CLBEnvironmental qualification of electrical equipment consistent with CLBFatigue Analysis consistent with CLBEAF analysis consistent with GALL-SLR guidanceEAF Screening methodology for limiting Class 1 locationsAny changes in Technical Specifications anticipated for SLR?Is Noble Metal Chemical Addition or Hydrogen Water Chemistry credited in reducing ISI inspection requirements?Will BWRVIP-62 Rev. 1 be used for BWR Vessel and Internals? Concrete degradation including irradiation effects 8

Discussion Topics/Lessons LearnedCable and Electrical AMPs BWRVIP Integrated Surveillance Program (ISP)BWRVIP-135 BWRVIP-86 Rev. 1-AUse of the BWRVIP-74 App. B generic equivalent margins analysis methodology for Upper Shelf Energy (USE) TLAA Any new aging effects identified for SLR?Westinghouse Steam Dryer aging managementUse of SLRA Appendix CRelationship between 1 st and 2 nd LR UFSAR supplements 9

Project Management Exelon plans to provide electronic SLRA submittal, web-ready CD and reviewers' aid information including: Reviewer version CDs including SLRA, ER, boundary drawings, UFSAR, and FPP, with links SLRA and boundary drawing hard copies will be providedExelon will utilize Scientech eDocs portal to make supporting documents available upon NRC completion of SLRA acceptance reviewFrequent project calls between the Exelon Licensing Lead and NRC PMOperating Experience Audit in Rockville, MDExelon will support with utility laptops, spreadsheet data and connection to Station CAP databaseIn-Office and On-Site Audit SupportExelon will work with NRC PM to establish and manage remote breakout session schedulesExelon will track NRC audit questions, requests, and the responses in a databaseCoordination of plant walkdownsand other on-site activitiesRAI ResponsesExelon will meet NRC response schedules 10 Closing RemarksThe Peach Bottom SLR application will be consistent with GALL-SLR and GEIS to the greatest extent possibleExelon will submit a high quality application that can support an 18 month staff reviewRecent industry RAIs addressed in the SLR application Timely RAI responsesFrequent NRC interfaceThe Peach Bottom SLR application is on track to be submitted to the NRC in 3 rdquarter 2018 11 Questions?
