Overview

• SLRA Guidance

• Preparing for NRC review of SLRA

• Lessons Learned from review of first SLRA 3

SLRA Guidance

• 2008 - 2011 - international workshops on LTO

• 2011-2014 - collected proposed changes to technical guidance

• SECY 14-0016 and SRM - no rulemaking

• 2014 - expert panel meetings

• 2015 - draft guidance documents published

• Feb. 2017 - engaged ACRS on draft guidance 4

SLRA Guidance (cont.)

• July 2017 - published final SLRA guidance o Final GALL-SLR (NUREG-2191, Vols. 1 and 2) o SRP-SLR (NUREG-2192)

• December 2017 - Published companion documents o NUREG-2221 (Technical Bases for Changes in the Subsequent License Renewal Guidance Documents, NUREG-2191 and NUREG-2192), and o NUREG-2222 (Disposition of Public Comments on the Draft Subsequent License Renewal Guidance Documents, NUREG-2191 and NUREG-2192) 5

SLRA Guidance (cont.)

• December 2017 - NRC issues interim endorsement letter for NEI guidance o NEI 17-01, Industry Guidance for Implementing the Requirements of 10 CFR Part 54 for Subsequent License Renewal, Rev. 0 o NEI 17-04, Model SLR New and Significant Assessment Approach for SAMA, Rev. 0

SLRA Guidance (cont.)

• New GALL-SLR AMPs

• Fluence Monitoring

• High Voltage Insulators

• Deleted AMPs

• Feedwater nozzle and control rod drive return line nozzle

• Withdrawal and testing of at least one reactor vessel surveillance capsule addressing the subsequent PEO (if specified criteria not already met) 7

SLRA Guidance (cont.)

• A plant-specific analysis for inspection of PWR reactor vessel o to address differences from first license renewal period to subsequent license renewal period

• Expanded AMPSs for Electrical Insulation of Cables from one to three o to address aging of submerged cables at different voltages

• Aging management of concrete o Updated for alkali-silica reaction o Added further evaluation for irradiation of concrete

• Added over 1035 new items to GALL-SLR tables 8

Preparing for NRC Review

• Communicate with NRC - frequently / timely

• Communicate w/other applicants / prospective

• Peer reviews

• Review most recent NRC RAIs

• Ensure internal application consistency

• Ensure CLB issues are addressed prior to SLRA

• Address NRC concerns from previous reviews (ML17353A035)

• Facilitate the NRCs review 9

Preparing for NRC Review

• Pre-Submittal Meetings

• Environmental at least 12 months prior to submittal

• Safety at least 6 months prior to submittal

• Referencing unapproved Topical Reports or unapproved methodologies

• Proprietary information

• Portal for documentation

• Update program for consistency with GALL-SLR and SRP-SLR 1

Review Process Changes

• SLR Application (SLRA) review optimization effort identified several changes

• Piloted on River Bend license renewal review

• Pre-submittal meetings

• SLRA acceptance review performed by technical staff assigned to review v. tiger team approach

• 18 month schedule begins upon SLRA acceptance for docketing 1

1

Review Process Changes

• Applicant provides access to electronic portal (no later than acceptance of the SLRA in order to support the review schedule)

• Aging Management Audits (Safety) o Offsite Aging Management Program Operating Experience Audit o In-Office Aging Management Audit via telecom/webinar breakout sessions o On-Site Aging Management Audit with regional participation to walk down specific material conditions and plant configurations 1

2

Review Process Changes

• Documents and meetings o Draft SEIS public meeting if necessary (environmental) o Streamlined SER process o Advisory Committee on Reactor Safeguards (ACRS) meetings on safety review - only one ACRS Subcommittee meeting o ACRS Full Committee meeting scheduled within two months following SC meeting 1

Lessons Learned Review of first SLRA

• Proprietary Application

• Proprietary Information

• review of prop info must be completed before application can be made public

• resulted in delays beginning acceptance review

• Acceptance Review

• issues raised challenged timely acceptance review

• Issues raised potentially impacted review schedule

• review schedule begins upon docketing 1 4

Lessons Learned Review of first SLRA

• Frequent communication

• Application content

• Topical report references

• use of unapproved methodologies

• ensure sufficient detail for SER conclusion

• OpE Audit successful

• Environmental audit coordination

• Portal issues 1
