March 15, 2019 MEMORANDUM TO: Jennivine Rankin, Acting Chief Licensing Branch 3 Division of Licensing, Siting, and Environmental Assessment Office of New Reactors FROM: Mallecia A. Sutton, Senior Project Manager /RA/
Licensing Branch 3 Division of Licensing, Siting, and Environmental Assessment Office of New Reactors
SUBJECT:
SUMMARY
REPORT FOR THE ENVIRONMENTAL AUDIT OF PART 3 OF THE NUSCALE DESIGN CERTIFICATION APPLICATION By letter dated December 31, 2016, NuScale Power, LLC (NuScale), submitted its Design Certification Application (DCA) to the U.S. Nuclear Regulatory Commission (NRC) for review (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17013A229). On March 15, 2017, the NRC staff accepted the DCA for docketing and initiated its technical review.
The NRC staff conducted an audit from August 14, 2017, to February 28, 2018, of the documentation supporting the DCA Part 3, containing Applicants Environmental Report -
Standard Design Certification, herein denoted as the Environmental Report (ER). The NRC staff audited the methodology, models, assumptions, and calculation packages in support of the ER. The audit plan used to support these interactions can be found under ADAMS Accession No. ML17179A287, and the audit summary is under ADAMS Accession No. ML18143B667.
The NRC staff identified a need for a second environmental audit of NuScales design and severe accident mitigation design alternatives. In doing so, the NRC staff audited the supporting information presented in Revision 1 of the ER, including non-docketed supporting documents. The NRC staff also determined an audit would be needed in identifying and resolving specific information needs to support the NRC staffs independent evaluation and confirmatory analysis for the regulatory findings required under Title 10 of the Code of Federal Regulations Part 51 (see Appendix B for the list of information needs).
CONTACT: Mallecia A. Sutton, NRO/DLSE 301-415-0673
J. Rankin The audit began October 16, 2018, and ended on November 30, 2018. The audit summary report is enclosed.
