72.240—Conditions for spent fuel storage cask reapproval.
        
        (a) 
         The certificate holder, a licensee using a spent fuel storage cask, or the representative of a licensee using a spent fuel storage cask shall apply for reapproval of the design of a spent fuel storage cask.
    
    
        
        (b) 
         The application for reapproval of the design of a spent fuel storage cask must be submitted not less than 30 days prior to the expiration date of the CoC. When the applicant has submitted a timely application for reapproval, the existing CoC will not expire until the application for reapproval has been determined by the NRC. The application must be accompanied by a safety analysis report (SAR). The new SAR  may reference the SAR originally submitted for the approved spent fuel storage cask design.
    
    
        
        (c) 
         The design of a spent fuel storage cask will be reapproved if the conditions in  § 72.238 are met, and the application includes a demonstration that the storage of spent fuel has not significantly adversely affected structures, systems, and components important to safety.
