Nuclear Regulatory Commission September 26, 2024 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is soliciting public comment on its draft Interim Staff Guidance (ISG), DUWP-ISG-03, "Draft Interim Staff Guidance on Contamination Control, Radiological Survey, and Dose Modeling Considerations to Support License Termination at Sites with Environmental Discrete Radioactive Particle Contamination." The draft ISG addresses contamination control, radiological surveys, and dose modeling regarding discrete radioactive particles (DRPs) that are found in the environment due to an unplanned release or that potentially could be released to the environment during decommissioning. If finalized, this ISG would allow staff to develop consistent guidance regarding contamination control, particularly focused on non-diffuse contamination, during the decommissioning process, as well as provide acceptable survey approaches and dose methods for discrete radioactive particles until the appropriate NRC regulatory guidance can be updated.
