Simple power-law correlations have been deduced to predict the dependence of nondimensional thermal contact conductance on the nondimensional contact pressure for Zircaloy-2/uranium dioxide surfaces in contact. These correlations are based on the experimental results of several workers. These results indicate that further experimental work is needed to cover a broader range of pressures and temperatures and to ascertain the effect of mean junction temperature on the thermal contact conductance.
