NRC opens door to new Tennessee uranium enrichment mega-plant
Published Date: 8/12/2026
Notice
Summary
Orano Enrichment USA wants to build and run a uranium enrichment plant in Oak Ridge, Tennessee. The Nuclear Regulatory Commission is reviewing their license application and inviting the public to request a hearing if they have concerns. This project could change how uranium is processed locally and involves important safety and security steps before moving forward.
Analyzed Economic Effects
6 provisions identified: 2 benefits, 3 costs, 1 mixed.
Orano license would allow uranium enrichment
Orano applied for a license to build and operate the Project IKE Enrichment Facility in Roane County (Oak Ridge), Tennessee, to re-enrich depleted uranium hexafluoride (UF6) tails and to enrich natural-grade UF6 up to a maximum of 8-weight percent uranium-235.
Financial qualifications: 30% equity and funding requirements
The NRC's guidance notes that, consistent with prior precedent, an applicant may be required before construction to provide a minimum equity contribution of 30% of project costs from parents/affiliates, firm funding commitments for remaining project costs, and long‑term contracts with prices sufficient to cover construction and operating costs.
Access rules and $403 fee for SGI background checks
Potential parties who need access to Safeguards Information (SGI) or Sensitive Unclassified Non‑Safeguards Information (SUNSI) must request access (SUNSI/SGI requests for contention preparation must be made within 10 days of this notice), and SGI access requires completion of Form SF-85, Form FD-258 fingerprint cards, a background check, and payment of a $403.00 fee per individual to the NRC.
Depleted UF6 tails to be treated as waste unless use shown
The Commission states that depleted uranium hexafluoride (depleted tails) will be considered waste in environmental documents unless Orano demonstrates a use for the material; disposition approaches consistent with the USEC Privatization Act, including transfer to DOE for disposal, are identified as plausible strategies and Orano must address onsite storage health, safety, and security pending removal or DOE disposition.
60-day window to request a contested hearing
Any person whose interest may be affected has 60 days from this notice's publication (August 12, 2026) to file a request for a hearing and petition to intervene under the NRC rules; petitions filed after 60 days will not be considered except for good cause under 10 CFR 2.309(c)(1)(i)-(iii).
Licensing Board timing: 140 and 315 day deadlines
The Licensing Board must issue a contention-admissibility decision no later than 140 days from this Federal Register notice and the Commission expects a final Licensing Board decision within 315 days from the publication date (August 12, 2026).
