A cylindrical nuclear fuel element is 10 cm long and 12 cm in diameter. The fuel generates heat uniformly at a rate of 50×10^3 kJ/s.m3. The fuel is placed
in an environment having a temperature of 360K with a surface coefficient of 4500 W/m2. The fuel material has k=34 W/m.K. For the situation described, please evaluate
the following at steady state (end effect may be neglected):
(a) The temperature profile as a function of radial position
(b) The surface temperature
