## II. Discussion

                    Since 1988, NRC licensees have been required to provide decommissioning financial assurance. The NRC published its “Decommissioning Planning Rule” in the                     **Federal Register**                     on June 17, 2011 (76 FR 35512). The rule became effective on December 17, 2012. The rule's purpose is to minimize the likelihood of new “legacy sites,” those sites owned or controlled by licensees with insufficient resources to complete decommissioning. Successful completion of decommissioning is a prerequisite to the NRC terminating the license.                

                    The NRC's radioactive materials licensing regulations, part 30 of Title 10 of the                     *Code of Federal Regulations*                     (10 CFR), “Rules of General Applicability to Domestic Licensing of Byproduct Material”; 10 CFR part 40, “Domestic Licensing of Source Material”; and 10 CFR part 70, “Domestic Licensing of Special Nuclear Material,” require NRC licensees to provide adequate financial assurance for all decommissioning activities.[1]                                          The NRC staff utilizes NUREG-1757, Vol. 3 (ADAMS Accession No. ML12048A683), as guidance to evaluate DFPs submitted by 10 CFR parts 30, 40 and 70 licensees. The NRC's Regulatory Guide (RG) 4.22, “Decommissioning Planning During Operations” (ADAMS Accession No. ML12158A361), provides guidance to licensees for use during licensed operations to minimize radiological contamination, including radiological subsurface contamination, and to properly retain survey results. For those licensees having or likely to have significant residual radioactivity, RG 4.22 provides guidance on arranging for sufficient funding to complete decommissioning, thereby allowing the NRC to terminate the license.                

The purpose of this ISG is to provide NRC staff and industry with guidance based on developments and lessons learned in financial assurance since the last update to NUREG-1757, Vol. 3. The ISG covers decommissioning cost estimates describing current facility conditions, evaluating events since the last DFP approval, and updates for certain financial instruments.

Dated at Rockville, Maryland, this 26th day of July, 2018.

For the Nuclear Regulatory Commission.

John R. Tappert,

Director, Division of Decommissioning, Uranium Recovery and Waste Programs, Office of Nuclear Material Safety and Safeguards.
