The LTR was submitted by letter dated December 30, 2022 (Agencywide Documents Access and Management System [ADAMS] Accession Nos. ML22364A333 [proprietary] and ML22364A332

[nonproprietary]). The NRC staff has reviewed the submitted information and found that it does not provide sufficient technical information to enable the NRC staff to complete a detailed technical review.

The NRC staff requests that NuScale address the Requests for Supplemental Information (RSIs) identified in the NRC letter dated March 17, 2023 (ML23058A160) by September 15, 2023. Following receipt of the identified supplemental information, the NRC staff will establish 1) a detailed review schedule, which may be longer or shorter than the generic review schedule, and 2) a projected level of effort to complete the detailed technical review. If the information requested by the NRC staff is not received by the above date, the application will not be docketed for review.
