Issues related to the transport of a transportable storage cask after storage

In this paper an evaluation is performed to assess whether the reliability of a transportable storage cask system and the risks associated with its use are comparable to those associated with existing transport cask systems and, if they are not, determine how the transportable storage cask system can be made as reliable as existing systems. Reliability and failure mode analyses of both transport-only casks and transportable storage casks and implementation options are compared. A summary assessment of the considerations for deploying a transportable storage cask (TSC) system with emphasis on preliminary design, validation, and operational recommendations for TSC implementations is presented. The analyses conclude that a transportable storage cask can likely by shipped unopened by applying a combination of design considerations and operational constraints, including environmental monitoring and pretransport assessments of functional reliability of the cask. A proper mix of these constraints should yield risk parity with any existing transport cask
