3150-AJ78 201610 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 3150 Nuclear Regulatory Commission NRC List of Approved Spent Fuel Storage Casks – EnergySolutions Corporation, VSC-24 System, Renewal of Initial Issue and Amendments 1 Through 6 of Certificate of Compliance No. 1007 [NRC-2016-0138]

This rule is to renew CoC 1007 for Ventilated Storage Cask model VSC-24 for an additional 40 years. It will also amend the CoC to prohibit the construction or placement into service of new VSC-24 structures, systems, or components (SSCs). General licensee users with VSC-24 systems in service as of the renewal’s effective date, however, may continue to perform SSC maintenance and repairs in accordance with the conditions of this CoC. The rule will require each user to establish, implement, and maintain written procedures for each aging management program (AMP), including a lead cask inspection program, and conduct periodic tollgate assessments as part of the Operating Experience element of each AMP. To preclude possible zinc-zircaloy interactions in VSC-24 casks loaded after the effective date of the CoC renewal and its amendments, an additional technical specification will limit the maximum decay power per assembly to 0.625 kW.
