Transcribed Image Text: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,
