Discussion</HD> The NRC is withdrawing RG 3.65, “Standard Format and Content of Decommissioning Plans for Materials Licensees.” RG 3.65 provides guidance on the decommissioning leading to termination of a materials license. In May 2008, RG 3.65, Revision 1, was issued and endorsed the method described in NUREG-1757, Volume 1, Revision 2 (ADAMS Accession No. ML063000243), to provide applicants and licensees with consolidated and updated guidance for decommissioning to support termination of a materials license. The NRC staff uses NUREG-1757 as the primary guidance document while reviewing these applications and licenses. Since NUREG-1757 provides the most current guidance, the NRC has determined that RG 3.65 is no longer needed. The withdrawal of RG 3.65 does not alter any prior or existing NRC licensing approval or the acceptability of licensee commitments to RG 3.65. Although RG 3.65 is being withdrawn, current licensees may continue to use it, and this withdrawal does not affect any existing licenses or agreements. However, applicants and licensees should use NUREG-1757 to support future requests or applications for NRC licensing actions related to the guidance in RG 3.65. <HD SOURCE="HD1">II.
