A fuel plate is of half width a=10 mm and is clad in a zircaloy sheet of thickness Oglad=2 mm. The heat is generated uniformly in the fuel. Kuo2-3 W/m°K, kuc=30 W/m°K, kolad=17 W/m°K a) Compare the temperature drop across the fuel plate when the fuel is UO, plate to that of a UC fuel for the same heat-generation rate (i.e., calculate the ratio of Tmax-Teo for the UO, plate to that of the UC plate.) b) Nuclear safe guard committee want to make sure that the peak temperature of the UO, fuel plate will not exceed 500 °C. Upon this constraint, you are to design a minimum convective heat transfer coefficient outside the fuel plate. Then what is the minimum heat transfer coefficient of water to fulfill your task? Assume the bulk fluid temperature far away from the fuel plate is 50 °C. Also the heat flux of UO, fuel plate is 100 kW/m? (10 points).
