Nuclear fuel rods. A typical nuclear fuel rod contains circular uranium oxide (UO2) fuel pellets 10 mm in diameter and 5-mm thick stacked in a column to a length of 4 m inside a thin zirconium alloy tube, as shown below. The pellets generate heat uniformly throughout their volume due to nuclear fission, with a power density a (i.e., the heat power produced per unit volume of the pellet) that depends on their 235U enrichment. This heats up the water in the reactor to produce steam to drive the turbine. Assuming that the rim of the fuel pellet is maintained at a constant temperature Trim due to water cooling, show that the steady-state temperature profile T(r), where r is the radial distance from the centre of the pellet and fuel rod, 4. P(R? -r²; is given by: T(r) = Tim + 4k where k is the thermal conductivity of the pellet and R is its radius. partial stacked column of fuel pellets in rod
