A nuclear fuel element is in the form of long solid cylindrical rod (k=0.85 W/mK) of diameter 14 mm is generating heat at an uniform rate of 0.45×108 W/m3 because of nuclear fission. Heat is transfer to pressurized cooling water at 300 0C and surface heat transfer coefficient is 4500 W/m2k. calculate the maximum temperature in the fuel rod in the system. What is the change in Tmax if the fuel element is encapsulated in a thin metal cladding of thickness 0.5 mm. Neglect thermal resistance of the cladding.
