The intergenerational storage and subsequent transport of Dual Purpose Casks; the creation of a hybrid storage and transport culture

The storage of packaged radioactive waste with the intention of transporting the waste at some time in the future for processing or disposal is not a new concept. However, the growing adoption of using dual purpose casks (DPC) containing spent fuel assemblies to store the spent fuel and then transport the DPC from the nuclear facility to another facility to process or dispose of the spent fuel, is a practice that continues to gain popularity and adoption over the past two decades. Whilst this strategic choice has operational advantages, there are intergenerational issues that will need careful consideration and planning to ensure the transports are able to take place decades in the future. This paper describes a model of a hybrid storage and transport culture which addresses the compliance of the DPC design with transport regulations, the DPC storage regime required by the transport safety case, and other issues to be considered when planning the transport program for a time several generations in the future.
