NRC proposes rule for decommissioning timelines, groundwater protection
The Nuclear Regulatory Commission is proposing a new rule that addresses two different aspects of agency oversight. In “In Situ Recovery Monitoring and Decommissioning Timeliness,” published online on September 1, the NRC proposes in the first part of the new rule to establish risk-informed criteria for protecting drinking water from radiological and nonradiological contamination near uranium in situ recovery (ISR) sites. In the second part of the rule, the NRC proposes to streamline the process for extending decommissioning timelines for all licensees.
