Derive an expression for temperature distribution


a) Derive an expression for temperature distribution T (r) in the UO2 fuel of a PWR. Assume that temperature of the cooling water, the gap, and the thickness of the cladding are known.

b) Using the typical data for the PWR fuel rods, calculate the maximum temperature in the fuel. The conductivity of UO2 is k UO2 = 2 W/m-K. The conductivity cladding is 22 W/m-K.
