This paper deals with a computer aided temperature measuring system for real time Prediction of fluid temperature from outer surface of the cooling pipe of fast reactors. Numerical simulations using 2-dimensional transient analysis code and water experiments for a parallel wall geometry were carried out to show the applicability of this temperature measuring system. The wall was a 10 mm thick stainless steel plate. Hot water flowed downward in the gap between the vertical parallel walls. Temperatures on the inner surface and outer surface and also the bulk temperature of the fluid were measured in the experiments. The numerical simulations were also carried out in the same geometry. Inverse heat conduction method was used to estimate the bulk temperature in the fluid flow from the measured temperature at the back surface. It was shown that heat transfer coefficient at the inner surface is significant to predict the bulk temperature. The numerical simulations for sodium showed that the prediction based on the inverse heat conduction method is more applicable to the sodium system than that to the water system.
