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).

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.
