title: Partial site release at a power reactor facility.
abstract: U.S. NRC licensed facilities undergoing decommissioning may wish to remove portions of their site from the jurisdiction of their license, prior to final license termination. The method of partial site release, relevant to radiological conditions, described herein employs NUREG-1505 methodology for demonstrating indistinguishability from background. The partial site release process was also informed by NRC Regulatory Issue Summary 2000-19 "Partial Release of Reactor Site for Unrestricted Use Before NRC Approval of the License Termination Plan." However, the focus of this discussion is the radiological aspects of partial site release, relevant to the implementation of NUREG-1505 methodology for demonstrating indistinguishability from background, based on the 137Cs concentrations at the site and a suitable background reference area. This type of approach was found acceptable by the NRC, and the partial site release was granted.
