Terrestrial Energy USA - Audit Plan for TR POSTULATED INITINIATING EVENTS FOR THE IMSR400 REVISION A.pdf Good afternoon, Terrestrial Team,

By letter dated December 27, 2024, Terrestrial Energy USA (TEUSA), submitted the topical report Postulated Initiating Events for the IMSR400, Revision A, for the NRC staff review and safety evaluation. The NRC staff has determined that a regulatory audit would assist in the clarification, understanding, and verification of the information contained in this topical report.

The audit plan does not contain questions, rather, it outlines the purpose, scope, potential information subject requests, logistics of the audit, and deliverables to support the initial setup of the audit between Terrestrial and the NRC. The audit plan is attached to this email and will be available in ADAMS under ML25118A101.

Initial questions are expected to be communicated in early June 2025 and an audit kick-off meeting will be scheduled following your receipt of these questions.

This transmittal email will be placed in ADAMS and declared as an official record. If you have any questions, please contact me at (301) 415-0365 or via email.
