CASTOR X/32 S Design and Licensing Status

The CASTOR® X/32 S cask is designed for storage and transportation of thirty-two spent nuclear fuel assemblies from U.S. PWRs. The criteria for acceptance of spent-fuel assemblies for storage in the CASTOR® X/32 depends on their enrichment, burnup and cooling time. These parameters are used to determine the source terms for criticality, shielding, and thermal analyses. On the basis of these analyses, the final layout of the cask was performed.
