General Atomics (GA) is developing two legal-weight-truck spent-fuel shipping casks for transporting commercial reactor spent fuel. The GA-4 pressurized-water-reactor (PWR) and the GA-9 boiling-water-reactor (BWR) casks are stainless steel with non-circular cross sections. Depleted uranium (DU) and boron polypropylene are used for gamma and neutron shielding. Solid pellets of boron carbide contained in a removable stainless steel fuel support structure provide criticality control. The GA-4 Cask utilizes burnup credit to maintain a capacity of four spent fuel assemblies for enrichments greater than 3.0 U-235 wt%. Aluminum honeycomb impact limiters and a dedicated semitrailer contribute to the overall efficiency and safety of the system. Design verification testing of a half-scale model cask will confirm the adequacy of the structural design.
