TerraPower Natrium EI-NI Separation TR Audit Summary Final.docx Dear Mr. Wilson
Attached is the summary report of an audit conducted by U.S. Nuclear Regulatory Commission (NRC) staff (the staff) of the TerraPower topical report (TR) NATD LIC RPRT 0001, Regulatory Management of Natrium Nuclear Island and Energy Island Design Interfaces (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22277A824), submitted October 4, 2022. The TR contains a summary of the Natrium reactor plant design, interfaces, and safety features; and of TerraPowers process for classifying structures, systems, and components (SSCs); basic plant transient analyses; and evaluation of select NRC regulations relevant to Natriums proposed nuclear island (NI) and energy island (EI). TerraPower requested NRC review and approval of the subject TR to serve as a means, via reference, for Natrium reactor licensees to utilize the regulatory evaluation.
The purpose of the audit was to enable NRC staff to gain a better understanding of the analyses referenced in the TR and the extent to which they support the conclusions drawn in the TR regarding the independence of the Natrium NI and EI.
- Thanks,
