{"abstract":"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.","action":"Opportunity To Request a Hearing and To Petition for Leave to Intervene; Order Imposing Procedures.","agencies":[{"raw_name":"NUCLEAR REGULATORY COMMISSION","name":"Nuclear Regulatory Commission","id":383,"url":"https://www.federalregister.gov/agencies/nuclear-regulatory-commission","json_url":"https://www.federalregister.gov/api/v1/agencies/383","parent_id":null,"slug":"nuclear-regulatory-commission"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/07/27/2026-15130.html","cfr_references":[],"citation":"91 FR 46971","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"A request for a hearing or petition for leave to intervene must be filed by September 25, 2026.
