NRC Okays St. Lucie Nuke Tweaks, Locks Down Secret Docs
Published Date: 8/11/2026
Notice
Summary
The U.S. Nuclear Regulatory Commission (NRC, the Commission) received, and is considering approval of, one request to amend two licenses. The license amendment request is for St. Lucie Plant, Unit Nos. 1 and 2. For the license amendment request, the NRC proposes to determine that it involves no significant hazards consideration (NSHC). Because the amendment request contains sensitive unclassified non- safeguards information (SUNSI), the NRC is issuing an order imposing procedures to obtain access to SUNSI for contention preparation by persons who file a hearing request or petition for leave to intervene.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 0 costs, 1 mixed.
St. Lucie License Amendment Reviewed
The NRC is considering a license amendment for St. Lucie Plant, Unit Nos. 1 and 2 (application dated April 13, 2026) that would exclude dynamic effects of postulated pipe ruptures in certain Class 1 auxiliary systems and expand the leak-before-break method to pressurizer surge, shutdown cooling, and safety injection tank piping. The NRC has proposed a "no significant hazards consideration" (NSHC) and may issue the amendment before the normal 60-day notice period if it determines NSHC or if delay would lead to derating or shutdown.
Rules to Get Sensitive SUNSI Documents
If you want to intervene in this proceeding and need access to Sensitive Unclassified Non-Safeguards Information (SUNSI), you must request access within 10 days after the Federal Register notice (deadline August 21, 2026). Requests must include a description of the licensing action, your name and address and a particularized interest, and why public information is insufficient; the NRC staff will decide within 10 days of receipt whether you likely have standing and a need for SUNSI, and if access is granted you may have to sign a Non-Disclosure Agreement or Protective Order. Comments are due by September 10, 2026; petitions to intervene or requests for hearings are due by October 13, 2026; and any contentions based on SUNSI information must be filed no later than 25 days after you receive that information.
