II. Discussion By letter dated November 21, 2022 (ADAMS Accession No. ML22325A349), NuScale informed the NRC of its intent to submit an SDA application in stages, along with supporting technical reports, by December 31, 2022. By letter dated November 23, 2022, NuScale submitted the first part of its application (non-public, withheld pursuant to 10 CFR 2.390) for a standard design approval of the NuScale US460 SMR design, pursuant to Section 103 of the Atomic Energy Act of 1954, as amended, and part 52, subpart E, of title 10 of the Code of Federal Regulations (10 CFR), ``Licenses, Certifications, and Approvals for Nuclear Power Plants.'' Subsequently, NuScale submitted the remaining portions of its application in stages, between November 29, 2022, and December 31, 2022. The SDA application is available in ADAMS under Package Accession No. ML22339A066. The NuScale US460 SMR is a pressurized-water reactor. The design is based on the Multi-Application Small Light Water Reactor developed at Oregon State University in the early 2000's. The NuScale US460 SMR is a natural circulation light-water reactor with the reactor core and helical coil steam generator located in a common reactor vessel in a cylindrical steel containment. The NuScale power module is partly immersed in water in a safety related pool. The reactor pool is located below grade and is designed to hold up to six power modules. Each NuScale SMR has a rated thermal output of 250 megawatts thermal and an electrical output of 77 megawatts electric (MWe); accordingly, a plant containing six modules would have a total capacity of 462 MWe. As described in the November 21, 2022, letter, the application contains the final safety analysis report (FSAR) chapters and parts thereof. Supporting technical reports are cited throughout the application, some of which are attached to the corresponding FSAR chapter; other technical reports cited in the application are available as standalone documents in ADAMS, if publicly available. Following these submittals, NuScale submitted additional supporting licensing topical reports (LTRs), which were required to be submitted before the SDA application could be accepted for review. By January 8, 2023, NuScale submitted these LTRs to the NRC. A notice of receipt and availability of this portion of the application was published in the Federal Register on March 17, 2023, (88 FR 16463). On March 17, 2023 (ADAMS Accession No. ML23058A160), the NRC staff notified NuScale that its staged SDA application, the last submittal of which was provided on December 31, 2022 (ADAMS Package Accession No. ML22339A066), will be considered tendered but not docketed until the Request for Supplemental Information (RSI) enclosed in the March 17 letter is submitted and the SDA application is found to be acceptable for detailed technical review by the staff. On July 14, 2023 (ADAMS Accession No. ML23195A092), NuScale submitted the response to the staff's RSI. Additionally, on July 17, 2023 (ADAMS Accession No. ML23198A244), NuScale submitted Licensing Topical Report (LTR) TR- 131981, ``Methodology for the Determination of the Onset of Density Wave Oscillations (DWO),'' Revision 1, that incorporated changes resulting from NuScale's RSI response. The NRC staff has determined that the SDA application, as supplemented, is acceptable for docketing under Docket No. 52-050. The NRC staff provided NuScale notice of the staff's determination that its application was acceptable for docketing by letter dated July 31, 2023 (ADAMS Accession No. ML23198A163). [[Page 51876]] III. Opportunity to Comment In accordance with 10 CFR 2.110(b), the NRC staff is inviting public comments on the SDA application within 60 days of publication of this notice, for consideration by the NRC staff and Advisory Committee on Reactor Safeguards in their review of the application. Comments should be submitted as described in the ADDRESSES section of this document. The NRC staff will perform a detailed technical review of the SDA application and will document its safety findings in a safety evaluation report. Docketing of the application does not preclude the NRC from requesting additional information from the applicant as the review proceeds, nor does it predict whether the Commission will grant or deny the application.
