Regulatory Guide: Standard Format and Content of Decommissioning Plans for Materials Licensees

Document 2025-06107 is a Final Rule published by the Nuclear Regulatory Commission in the Federal Register on April 9, 2025, with an effective date of April 9, 2025. The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Regulatory Guide (RG) 3.65, "Standard Format and Content of Decommissioning Plans for Materials Licensees." This RG is being withdrawn because it is not needed to endorse NUREG-1757, "Consolidated Decommissioning Guidance: Decommissioning Process for Materials Licensees," Volume 1, "Decommissioning Process for Materials Licensees." NUREG-1757 provides the most current guidance on decommissioning nuclear facilities to support license termination for applicants, licensees, and NRC staff reviewers.
