Discussion

On March 28, 2024, TerraPower, LLC (TerraPower), on behalf of US SFR
Owner, LLC., a wholly owned subsidiary of TerraPower, filed an application for a
construction permit for a single-unit power reactor facility located in Lincoln County,
Wyoming, pursuant to section 103 of the Atomic Energy Act, as amended, and part 50 of
title 10 of the Code of Federal Regulations (10 CFR), “Domestic Licensing of Production
and Utilization Facilities.” The single-unit facility is to be identified as Kemmerer Power
Station, Unit 1 and would be based on the TerraPower and General Electric-Hitachi
Natrium reactor design which is a pool-type sodium fast reactor using metal fuel.
The application submitted on March 28, 2024, is available in ADAMS under
Package Accession No. ML24088A059. Along with other documents, the ADAMS
package includes the transmittal letter (ADAMS Accession No. ML24088A060), the
preliminary safety analysis report (ADAMS Accession No. ML24088A065), and the
environmental report (ADAMS Accession No. ML24088A072). The application was
supplemented on May 2, 2024 (ADAMS Accession No. ML24123A242). The information
submitted by the applicant includes certain administrative information submitted
pursuant to 10 CFR 50.33, such as on financial qualifications; technical information
submitted pursuant to 10 CFR 50.34; and the environmental report submitted pursuant
to 10 CFR part 51, “Environmental Protection Regulations for Domestic Licensing and

Related Regulatory Functions.” These notices are being provided in accordance with the
requirements in 10 CFR 50.43(a)(3).
The NRC staff is currently undertaking its acceptance review of the application. If
the application is accepted for docketing, a subsequent Federal Register notice will be
issued that addresses the acceptability of the construction permit application for
docketing and provisions for participation of the public in the permitting process.
