I.
BACKGROUND AND AUDIT BASIS By letter dated May 4, 2023, GE-Hitachi Nuclear Energy Americas, LLC (GEH) submitted Topical Report (TR) NEDC-33926P/NEDO-33926, Revision 0, BWRX-300 Steel-Plate Composite Containment Vessel (SCCV) and Reactor Building (RB) Structural Design, TR (ML23124A408). On July 31, 2023, GEH submitted supplemental information needed to inform an acceptance determination (ML23212B127) resulting in the NRC accepting the TR for review on August 9, 2023 (ML23220A016).
As prescribed by a September 2022, Charter - Collaboration on GEHs BWRX300 Design, (ML22284A024), the NRC and Canadian Nuclear Safety Commission (CNSC) are collaborating on the review of this TR. As a result, CNSC staff are participating in this audit.
This audit will be conducted in accordance with the guidance provided in the Office Instruction LIC 111, Regulatory Audits, (ML19226A274).
II.
OBJECTIVES The NRC and CNSC staff will seek clarification, gain understanding, and verify information related to the subject TR. The audit will identify if information is needed to support a regulatory finding so it can be placed on the docket. Additionally, review and discussion of the audit material will help focus any subsequent requests for additional information.
III.
REGULATORY AUDIT SCOPE The audit team will examine supporting documentation provided by GEH in the on-line portal, Certrec, and during virtual meetings. Audit topics include the initial information needs described below and any additional review needs identified in subsequent correspondence during the audit.
IV.
