Abstract in another language
Dual-purpose casks (DPC) for storage and transport of spent fuel assemblies (SFA) must meet certain criteria in order to ensure safe dissipation of decay heat and to prevent radiation of the environment. Among those are several temperature thresholds, which must not be exceeded, for example the peak fuel rod cladding tube temperature. In this work, we present a method to estimate the fuel rod cladding tube temperatures inside a DPC, incorporated in a user-friendly, resource-efficient simulation tool named Z88ENSI. This software has been developed in cooperation with the Swiss Federal Nuclear Safety Inspectorate ENSI, in order to have access to quick assessments of temperature fields inside DPC while maintaining low computational cost. The presented method allows the calculation of fuel rod cladding temperatures without the need for complete technical documentation of the respective SFA. The method is validated by comparison with literature and by elaborate simulations done with commercial finite element software. It is shown that the calculated temperatures are within reasonable deviations compared to data provided through available literature.
