March 12, 2019 MEMORANDUM TO: Jeremy S Bowen, Chief Beyond Design Basis Management Branch Division of Licensing Projects Office of Nuclear Reactor Regulation FROM: Joseph M. Sebrosky, Senior Project Manager /RA Juan Uribe for/
Beyond Design Basis Management Branch Division of Licensing Projects Office of Nuclear Reactor Regulation
SUBJECT:
SUMMARY
OF FEBRUARY 28, 2019, PUBLIC MEETING TO DISCUSS NUCLEAR REGULATORY COMMISSION STAFFS PRELIMINARY PROCESS FOR TREATMENT OF REEVALUATED SEISMIC AND FLOODING HAZARD INFORMATION On February 28, 2019 (Agencywide Documents Access and Management System (ADAMS)
Accession No. ML19052A511), the U.S. Nuclear Regulatory Commission (NRC) staff held a Category 3 public meeting to discuss the NRC staffs preliminary process for treatment of reevaluated seismic and flooding hazard information (ADAMS Accession No. ML19037A443).
The staff provided an overview of the preliminary process and then opened the meeting to questions and comments. The NRC staff also provided an e-mail account so that interested stakeholders could provide comments on the discussion paper through March 22, 2019. A list of individuals in attendance at the meeting can be found as an enclosure to this summary. The list does not include the approximately 48 people that attended the meeting via telephone. The NRC meeting handouts are available in ADAMS under Accession No. ML19042A683.
The staff noted that the process reflects the Commissions direction in the Affirmation Notice and Staff Requirements Memorandum (SRM) dated January 24, 2019 (ADAMS Accession No. ML19023A038), associated with SECY-16-0142, Draft Final Rule - Mitigation of Beyond-Design-Basis Events [MBDBE] (RIN 3150-AJ49), (ADAMS Accession No. ML16291A186). The staff highlighted the following attributes of the process:
- Based on the reevaluated seismic hazard information that has been provided to date, other than information associated with seismic probabilistic risk assessments (SPRA) reports, additional regulatory actions are not warranted.
- Based on the reevaluated flood hazard information that has been provided to date, the staff has identified the need to engage licensees for 21 sites to determine if licensees intend to treat actions that were described in their flooding mitigation strategies assessments (MSA) and flooding focused evaluations (FE) as regulatory commitments.
The understanding of the treatment of these actions is important for the staffs Phase 2 determination. The Phase 2 process is described in the March 12, 2012, Request for Information letter issued in accordance with Title 10 of the Code of Federal Regulations
J. Bowen Section 50.54(f) (ADAMS Accession No. ML12053A340) and as further described in a letter dated September 21, 2016 (ADAMS Accession No. ML16237A103).
- The staff will continue its assessment of SPRA reports, flooding FEs, and flooding integrated assessments (IAs) and will use the results of these assessments in the staffs Phase 2 determination.
- Based on the staffs assessment detailed in the discussion paper associated with the meeting, the staffs preliminary process would suspend its review of flooding and seismic MSAs. The majority of these MSAs have been evaluated by the staff. For the MSA reviews that have not yet been completed, or have not yet been submitted, the staff will evaluate mitigation strategies, as appropriate, as part of its review of SPRA reports, flooding FEs, and flooding IAs.
- Letter(s) will be issued related to the seismic and flooding reevaluations that document the staffs 50.54(f) backfit decisions in accordance with Phase 2 of the process and by the letter dated September 21, 2016. The letter(s) will bin sites according to the following four categories: Category 1 - no additional insights are needed; Category 2 -
additional insights are needed before a backfit decision is made; Category 3 -
corresponds to sites that have reevaluated seismic or flooding information that is currently being reviewed by the staff; and Category 4 - corresponds to sites that have had, or requested that, reevaluated hazard information submittals be deferred.
After addressing several questions associated with the process, the staff noted that stakeholders had until March 22, 2019, to provide their comments to an email account. The staff stated that it will adjust the process as appropriate based on stakeholder feedback.
