For the design of novel type of nuclear power plant, it is necessary to determine the temperature distribution in a large slab-type nuclear fuel element. Volumetric heat is generated uniformly in the fuel element at the rate of 2*107 W/m3 . This slab fuel is insulated on one side, while on other side it is covered by a stainless steel cladding of 0.3 cm thickness. Heat is removed from the fuel slab by a liquid at 2000C that flows on the other side of the steel cladding with the convective heat transfer coefficient of 10,000 W/(m2 K). Determine the maximum temperature in the fuel element and sketch the temperature distribution.
