Description of From-Reactor Transportation Cask Designs

As the Department of Energy's (DOE's) from-reactor cask development program contracts reach the end of preliminary design the program will proceed with two fully funded contracts. They are General Atomic's (GA's) contract for legal weight truck cask designs and Babcock and Wilcox's (B&JW's) contract for a rail/barge cask design. The designs are described in the paper. In addition, DOE will pursue specific design features with two of its cask contractors Westinghouse Electric Company (WEC) and Nuclear Assurance Corporation (NAC). The paper also presents several general considerations affecting the cask development program. Two of these which are covered in some detail are the technical topics of burnup credit and source term evaluation.
