SUMMARY
OF THE APRIL 25, 2023, OBSERVATION PUBLIC MEETING FOR DISCUSSION OF THE STATUS OF NUSCALES US460 STANDARD DESIGN APPROVAL APPLICATION The U.S. Nuclear Regulatory Commission (NRC) held an observation public meeting on April 25, 2023, to discuss topics related to NuScale LLCs (NuScale) US460 standard design approval (SDA) application (ML22339A066). This meeting was part of a periodic NRC and NuScale management engagement to discuss the status of the application, technical topics of interest, project processes and workflows. The meeting consisted of open and closed portions.
During the open portion of the meeting, the NRC staff gave an overview of the current status of the NuScale application that has been tendered but not docketed because of the technical sufficiency issues related to density wave oscillation (DWO) phenomena. The staff discussed the request for supplemental information (RSI) for DWO, the identified focus items that are needed to support a reliable schedule development (FISDs), and the High Impact Technical Issues (HITIs) contained in the in the NRC acceptance review letter (ML23058A160). The staff discussed the four-phase review approach that is being employed for portions of the applications safety review that are not affected by the DWO RSI. The staff also discussed the two audits that began on March 27, 2023; which started the Phase A safety review audit that includes the FISDs and HITIs, and an audit exclusively dedicated to the resolution of the DWO RSI.
