A design approach for qualifying the use of ductile cast iron spent fuel shipping casks in the USA
Recent ductile cast iron (DCI) research work, as applied to transport casks, in the United States has focused on developing a design methodology which could be used as acceptance criteria for DCI casks. Sandia National Laboratories has concentrated on advancing the linear elastic fracture mechanics design approach to cask design. The approach allows for the design of transport casks fabricated out of ferritic materials (such as DCI) which undergo a brittle/ductile failure mode transition. The Sandia program encompasses material characterization, finite element structural analysis, nondestructive examination evaluation and drop test verification. Recent results of the program and near-term efforts are described. 6 refs., 5 figs.
