Nuclear Regulatory Commission
The U.S. Nuclear Regulatory Commission (NRC) received a license application, by letters dated February 25, 2026, March 15, 2026, and April 17, 2026, from Radiant Nuclear, LLC (Radiant) to possess special nuclear material at its R-50 microreactor facility, to be located in Oak Ridge, Tennessee. Radiant requests a special nuclear material license to possess fuel, consisting of coated uranium particles enriched to less than 20 weight percent uranium-235 (U-235), and load the fuel into assemblies intended for use in commercial microreactors. Because the license application contains Sensitive Unclassified Non-Safeguards Information (SUNSI), an order imposes procedures to obtain access to SUNSI for contention preparation.
