SUPPLEMENTARY INFORMATION:

I. Discussion

    On October 20, 2026, Last Energy filed the first part of a two-part 
phased construction permit application for a utilization facility with 
the NRC, pursuant to Section 103 of the Atomic Energy Act of 1954, as 
amended, and

[[Page 69896]]

part 50 of title 10 of the Code of Federal Regulations (10 CFR), 
``Domestic Licensing of Production and Utilization Facilities.'' Part 
One of the application includes a LWA request submitted pursuant to 10 
CFR 50.10(d), ``Request for limited work authorization.'' Last Energy 
submitted part one of its application as part of a phased application 
approach for a construction permit for a utilization facility, as 
described in 10 CFR 2.101(a)(9) and 10 CFR 2.600(d).
    Last Energy's LWA application requests NRC approval to conduct 
certain early construction activities for its PWR-20 nuclear reactor at 
a site in Caldwell County, Texas. The requested LWA activities would 
include installation of permanent elements of the foundation supporting 
the reactor vessel, including subsurface preparation, grout backfill, 
installation of a steel liner, and driving of steel H-piles. The 
application also includes certain general and administrative 
information such as financial qualifications submitted pursuant to 10 
CFR 50.33, a preliminary safety analysis report submitted pursuant to 
10 CFR 50.34(a) for the portions of the facility within the scope of 
the LWA, an environmental report submitted in accordance with 10 CFR 
51.49(b) and (f), and a site redress plan.

II. Further Information

    If the NRC staff finds the LWA request acceptable for docketing, 
the staff will begin a detailed technical review. Subsequent Federal 
Register notices will address the acceptability of the tendered 
application for docketing and opportunities for participation of the 
public during the course of the staff's review.
    A copy of the application is available for public inspection at
