A spent-fuel shipping cask for use at both the Fast Flux Test Facility (FFTF) and the Clinch River Breeder Reactor Plant (CRBRP) is being developed. In compliance with milestones established for the Sandia Labs LMFBR spent-fuel shipping activity, conceptual designs of an LMFBR shipping cask are described. The detailed design based on one of the concepts will commence after review and comments have been received from the cognizant organizations. Conceptual designs described in this document comply with the shipping system requirements as defined in the LMFBR Spent-Fuel Shipping System Design Description. Additional considerations which have affected the conceptual designs currently being used are: (1) the rotating basket option has been excluded; (2) spent fuel must be adequately cooled during loading and unloading in a one-atmosphere argon environment; (3) passive cooling of the cask during shipment is required; (4) six-month cooled CRBRP fuel prescribes the radiation and thermal source; and (5) the shipping cask will be transported by rail. Heat transfer requirements during loading and unloading will substantially impact the shipping system. Spent-fuel assemblies may be placed in canisters containing a non-gaseous coolant prior to shipment or may be shipped bare subject to certain loading and cooling restrictions. The recommended option is to place a liquid metal in the canister and then insert the fuel assembly.
