Meeting info
The U.S. NRC is holding a public workshop on the technical basis for development of interim staff guidance or communications related to survey and dose modeling approaches for discrete radioactive particles to support license termination. This effort focuses on survey design considerations, including calculation of scan minimum detectable activities, and data quality objectives; internal dosimetry appropriate for discrete radioactive particles; and evaluation of exposure scenarios for DRPs. Technical reports and presentations are attached to the meeting notice. Feedback received during the workshop will be considered in determining the need for (and scope and content of) communications or interim staff guidance in this area. Interim staff guidance would be folded into a future revision of NUREG-1757, Volume 2, of NRC's Consolidated Decommissioning Guidance.
