I. Discussion

    On September 12, 2025, Atomic Alchemy Inc., on behalf of Atomic 
Alchemy Operators LLC and VIPR Idaho LLC, transmitted to the NRC the 
first part of an application, pursuant to section 103 of the Atomic 
Energy Act of 1954, as amended, and part 50 of title 10 of the Code of 
Federal Regulations (10 CFR), ``Domestic Licensing of Production and 
Utilization Facilities,'' for a construction permit for a four-unit, 
non-power, light-water-cooled, pool-type Versatile Isotope Production 
Reactor (VIPR) facility to be located at the Idaho National Laboratory 
desert site, in Bingham County, Idaho. Each VIPR unit utilizes low-
enriched fuel and contains irradiation positions for radiating targets. 
The VIPR units and related processing hot cells and target fabrication 
are referred to as the Meitner-1 facility.
    As part of the construction permit application, Atomic Alchemy 
Inc., on behalf of Atomic Alchemy Operators LLC and VIPR Idaho LLC, 
requested an exemption from certain requirements of 10 CFR 2.101(a)(5) 
that would allow the submission of the second part of the application, 
the environmental report, within six months of the first part.
    The first part of the construction permit application and the 
exemption request are available in ADAMS under Accession Nos. 
ML25255A199 (package) and ML25255A203, respectively.
    The NRC staff is currently reviewing the exemption request and 
undertaking its acceptance review of the first part of the construction 
permit application. If the exemption request is granted and the 
application is accepted for docketing, a subsequent Federal Register 
notice will be issued that addresses the acceptability of the first 
part of the application for docketing and provisions for participation 
of the public in the permitting process.
    A Federal Register notice of receipt and availability for the 
second part of the construction permit application will be issued after 
the NRC receives the second part of the application. If the second part 
of the application is accepted for docketing, a subsequent Federal 
Register notice will be issued that addresses the acceptability of the 
second part of the application for docketing and provisions for 
participation of the public in the permitting process.

    Dated: November 24, 2025.

Branch, Division of Advanced Reactors and Non-Power Production and
