Burnup Credit in the Criticality Safety Analyses of Pressurized Water Reactor Spent Fuel in Transportation and Storage Casks

摘要

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is issuing for public comment Draft Spent Fuel Storage and Transportation Interim Staff Guidance (SFST-ISG), SFST-ISG-8, Revision 3, "Burnup Credit in the Criticality Safety Analyses of PWR Spent Fuel in Transportation and Storage Casks." This SFST-ISG provides guidance for use by NRC staff when reviewing applications requesting burnup credit in the criticality safety analyses of pressurized water reactor spent nuclear fuel (SNF) in transportation packages and storage casks. The draft SFST-ISG proposes to revise the criticality safety review procedures and acceptance criteria contained in NUREG-1536, Revision 1, "Standard Review Plan for Spent Fuel Dry Storage Systems at a General License Facility," NUREG-1567, "Standard Review Plan for Spent Fuel Dry Storage Facilities," and NUREG-1617, "Standard Review Plan for Transportation Packages for Spent Nuclear Fuel."
