The temperature at the center of a fuel rod of UO₂ is 1220 F. Calculate the temperatures at the fuel-cladding interface at the outer surface of the cladding. The pellet is 0.158 in diameter, 30.5 long, and enriched with 26 wt.% U-235. The stainless-steel cladding is 0.005 thick. The thermal conductivity of U = 21.20 (BTU/HR-FT-F), UO₂ = 2.1 (BTU/HR-FT-F) and stainless-steel cladding = 13.5 (BTU/HR-FT-F). The max heat flux is 3.27x10⁸ Btu/hr-ft³.
