• In the previous report, we have analyzed the heat flow in an infinite unit column as a model of contact, assuming that two metals in contact are of same material and very thick. But in practice, heat is often conducted through thin and differnt metals in contact, as is seen in the case of uranium fuel and canning material in a nuclear reactor. Thermal contact resistance between the different and thin metals is analyzed and compared with the previous analysis. And this leads to the conclusions as follows : (1) If the thickness of a metal is larger than about 1 mm, the metal can be regarded as semi-infinite in the direction of heat flow. (2) If the conditions of two metals in contact, such as thermal conductivity, surface roughness, etc., are greatly differnt from each other, the calculation should be performed on a model which will be shown in this report.
