Vacuum drying of nuclear fuel canisters may cause the temperature of fuel assemblies to considerably increase due to the effect of gas rarefaction at low pressures. This effect may induce a temperature-jump at the gas-solid interfaces. It is important to predict the temperature-jump at these interfaces to accurately estimate the maximum temperature of the fuel assemblies during vacuum drying. The objective of this work is to set up a concentric cylinder experimental apparatus that can acquire data to benchmark rarefied gas heat transfer simulations and determine the thermal accommodation coefficient at the interface between stainless-steel surfaces and helium gas. The thermal accommodation coefficient is used to characterize the temperature-jump at the interface, and is determined by measuring the temperature difference and heat flux across a 2-mm gap between the concentric cylinders that contains rarefied helium and compare the results to analytical calculations in the slip rarefaction regime.
