AUDIT STATUS - THE STAFF REVIEW OF THE NUSCALE POWER, LLC STANDARD DESIGN APPROVAL APPLICATION - NUSCALE US460

Dear Ms. Fosaaen:

This letter provides the current status of the regulatory audit being conducted by the NRC staff as part of its safety review of the NuScale Standard Design App roval Application (SDAA) submitted stages, the last submittal of which was provided on D ecember 31, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 22339A066 and ML23131A300) and supplemented by letters dated July 14, 2023 (M L23195A092) and July 17, 2023 (ML23198A244). The staff began conducting the audit on Mar ch 27, 2023 (ML23067A300). The audit is intended to achieve efficiencies in the safety review by allowing the staff to review and discuss supporting material with the ob jective of improving communication and understanding of complex technical topics.

To date, the staff has presented 641 document requests and item s for explanation in the audit.

Of these, 332 items have been resolved in the audit, 201 items provided by NuScale are under review by the staff and 108 items are waiting for NuScale to pr ovide responses in the audit. The staff has communicated to NuScale that the following items rela ted to the final safety analysis report (FSAR) and the loss of coolant accident (LOCA) licensing topical report (LTR) resolved in the audit need to be submitted on the docket:
