Numerical Simulation of the Thermal Performance of a Dry Storage Cask for Spent Nuclear Fuel

In this study, the heat flow characteristics and thermal performance of a dry storage cask were investigated via thermal flow experiments and a computational fluid dynamics (CFD) simulation. The results indicate that there are many inner circulations in the flow channel of the cask (the channel widt...
