MEETING BETWEEN THE NRC STAFF AND NEXTERA ENERGY SEABROOK, LLC SEABROOK STATION, UNIT 1 LICENSE RENEWAL APPLICATION ROCKVILLE, MARYLAND MEETING
SUMMARY
MAY 9, 2017 After introductions, NextEra Energy Seabrook, LLC (NextEra or applicant), began the discussion by providing the status of the large-scale testing programs (LSTP), related to the concrete alkali-silica reaction (ASR) issue, conducted by MPR Associates, Inc (MPR) and Ferguson Structural Engineering Lab (FSEL) at the University of Texas at Austin. NextEra stated that the testing was completed in 2015. Beginning in April 2016, NextEra completed summary reports on the Test Programs, updated procedures and methodologies, and incorporated the results into the Structural Monitoring Program (SMP).
NextEra then described the Building Deformation analyses currently in progress. The purpose of these analyses is to demonstrate compliance with original design codes considering the impact of ASR on structural capacity and demand due to building deformation from ASR expansion. NextEra explained that the Building Deformation analyses should develop the monitoring parameters, their threshold limits, and inspection frequency for each structure, which will be the basis for the plant-specific aging management program (AMP). NextEra concluded the building deformation discussion by providing the schedule of completion. NextEra does not plan to complete the building deformation evaluation for the last impacted structure until the second quarter of calendar year 2018.
After NextEras presentation, the NRC staff reviewed the outstanding issues related to the safety review of the Seabrook Station, Unit 1 (Seabrook), license renewal application (LRA).
For the review of License Renewal Interim Staff (LR-ISG)-2016-01, Changes to Aging Management Guidance for Various Steam Generator Components, the staff issued Requests for Additional Information (RAIs) on March 16, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17066A488) and NextEras response is due May 19, 2017, which were submitted on May 30, 2017. For the resolution of questions regarding the Bolting Integrity AMP, the staff stated that it would issue the RAI by May 19, 2017, which was completed on May 25, 2017. Finally, regarding ASR, the NRC staff discussed that it may need an audit or additional RAIs once NextEra completes the Building Deformation analyses and factor the results into the LRA AMPs.
The last topic on the agenda was the potential to proceed with completing the review of the license renewal application separate from NextEras license amendment request, Seabrook Station, License Amendment Request 16-03, Revise Current Licensing Basis to Adopt a Methodology for the Analysis of Seismic Category I Structures with Concrete Affected by Alkali-Silica Reaction. NextEra stated that they do not believe that the license amendment request has an impact on completion of the safety review of the LRA. Specifically, NextEra stated that changes to the current licensing basis from the license amendment request will apply during the period of extended operation; therefore, NRC approval of the ASR evaluation methodology should be completed under the current licensing basis (Title 10 of the Code of Federal Regulation (10 CFR) Part 50, Domestic licensing of production and utilization facilities) and should not impact or delay the completion of the license renewal review under 10 CFR Part 54,
Requirements for renewal of operating licenses for nuclear power plants. NextEra further stated that they did not believe a license condition or commitment was necessary.
The staff noted that the ASR Monitoring Program is based on the testing completed at FSEL.
This testing program is unique, has not been reviewed and accepted by a consensus professional organization, has not been independently peer reviewed, and has not been reviewed and approved by the NRC. Therefore, in order for the ASR Monitoring Program to be found acceptable and proceed with the review of the LRA, the staff needs to review and accept the testing program and methodology. In addition, the staff stated that its evaluation of the adequacy of an AMP to manage certain aging effects for particular structures and components is based on its review of the 10 program elements, one of which is Parameters Monitored or Inspected. The parameters monitored or inspected by the Building Deformation Program is unique to each structure and is based, at least in part, on the testing program conducted by FSEL, meaning the staff needs to have confidence in the testing program and methodology through staff review and approval. Therefore, assuming there was no license amendment request, the staff would still need to evaluate the methodology in order to complete the review of the LRA.
NextEra and the NRC staff also discussed the potential of a license condition. The NRC staff stated that it would review any license condition that NextEra proposes but indicated that any potential license condition would need to comply with the Commissions regulations and orders on the purpose and scope.
Finally, NextEra and NRC staff discussed the following RAIs that were issued on March 29, 2017 (ADAMS Accession No. ML17088A614).
RAI B.2.1.31A-A1 ASRMP: Consideration of In-plane and Through-Thickness Expansion in Acceptance Criteria for Effect on Structural Limit States,
RAI B.2.1.31A-A4 ASRMP: Corroboration of Modulus - Expansion Correlation from FSEL Testing, and
RAI B.2.1.31B-B2 Parameters Monitored or Inspected for Building Deformation Monitoring Program.
The NRC staff reiterated the importance of timely response to any requests for information with respect to either the LAR or the LRA to ensure timely completion of the NRC reviews.
No regulatory decisions or commitments were made at the meeting. The staff will review the information submitted by NextEra as part of the LRA.
