This Standard Review Plan is intended for use by the U.S. Nuclear Regulatory Commission (NRC) reviewer. It provides guidance for the safety review of license (specific or general) and certificate of compliance (CoC) renewal applications submitted by licensees and holders of CoCs for dry cask storage systems (DCSSs), respectively, as codified in Title 10 of the Code of Federal Regulations (10 CFR) Part 72, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste, and Reactor-Related Greater Than Class C Waste." A license authorizes a licensee to store spent fuel in an NRC-approved DCSS at a site under the requirements of 10 CFR Part 72. To renew a specific license, an applicant must submit a license renewal application at least 2 years before the expiration of the license in accordance with the requirements of 10 CFR 72.42(b). To renew a general license, the general licensee or the CoC holder must submit a renewal application at least 30 days before the expiration of the associated CoC in accordance with the requirements of 10 CFR 72.240(b). The NRC may renew a specific license or a general license for a term not to exceed 40 years, in accordance with 10 CFR 72.42(a) or 10 CFR 72.212(a)(3), respectively.
