July 28, 2020 MEMORANDUM TO:
Michael I. Dudek, Chief New Reactor Licensing Branch Division of New and Renewed Licenses Office of Nuclear Reactor Regulation FROM:
Bruce M. Bavol, Project Manager /RA/
New Reactor Licensing Branch Division of New and Renewed Licenses Office of Nuclear Reactor Regulation
SUBJECT:
SUMMARY
OF THE JUNE 26, 2020, CATEGORY 1 PUBLIC TELECONFERENCE WITH NUSCALE POWER, LLC TO DISCUSS THE AUDIT EXIT OF THE NUSCALE BORON REDISTRIBUTION ISSUE On June 26, 2020, representatives from the U.S. Nuclear Regulatory Commission (NRC) and NuScale Power, LLC (NuScale), held a Category 1 public teleconference meeting to discuss the audit exit of the NuScale Boron Redistribution Issue. Participants included personnel from the NRC, NuScale, and two members of the public.
The public meeting notice can be found in the Agencywide Documents Access and Management Systems (ADAMS) under Accession No. ML20163A672. This meeting notice was also posted on the NRC public Web site located at https://www.nrc.gov/reactors/new-reactors/design-cert/nuscale/documents.html.
The Meeting Agenda is attached as an enclosure.
The NRC staff conducted an audit that initiated on March 4, 2020, and ended on June 26, 2020, to review several NuScale design changes associated with an issue related to boron redistribution that was identified in their design certification application.
CONTACT: Bruce Bavol, NRR/DNRL 301-415-6715
The NRC staff summarized that this regulatory audit was to: (1) better understand the impact of three submitted design changes on information related to Chapter 3, Design of Structures, Components, Equipment, and Systems; Chapter 4, Reactor; Chapter 5, Reactor Coolant System and Connecting Systems; Chapter 6, Engineered Safety Features; Chapter 7, Instrumentation and Controls; Chapter 13, Conduct of Operations; Chapter 15, Transient and Accident Analyses; Chapter 16, Technical Specifications; and Chapter 19, Probabilistic Risk Assessment and Severe Accident Evaluation, as well as associated technical and topical reports; (2) confirm information through examination of calculations and other information; (3) identify information that would require docketing to support a regulatory finding; and (4) ensure conformance with applicable NRC regulations.
At the end of the teleconference, the NRC staff solicited the public for input. One member of the public on the bridge line responded and asked if the probabilistic risk assessment (PRA) staff were satisfied with their part of the review. The PRA technical representative summarized the level of their review and explained that they were.
