= The fuel element in a nuclear reactor consists of a cylindrical thorium (k: = 55 Wm'K) fuel rod with 35 mm diameter that is wrapped in a 4.0 mm-thick aluminum (ka = 205 Wm--K) cladding. The fuel rod is in perfect contact with the cladding material so that contact resistances may be neglected. Thermal energy is generated in the fuel rod, and the cladding is cooled using 70C water with a convective heat transfer coefficient of 9.0 kWm K! a. Steady-state operation with uniform volumetric energy generation rate Qv = 2 = 600 MWm' in the fuel rod is proposed. The melting points of thorium and aluminum are 1755C and 660C, respectively. Is the proposed stead-state operation feasible? b. Is the proposed steady-state operation feasible if thermal energy is generated non-uniformly in the fuel rod according to 0; = 200 [1-5)*), where Q. is the mean volumetric generation rate, r is = the radial distance from the center of the fuel rod and r, is the radius of the fuel rod? = The fuel element in a nuclear reactor consists of a cylindrical thorium (k: = 55 Wm'K) fuel rod with 35 mm diameter that is wrapped in a 4.0 mm-thick aluminum (ka = 205 Wm--K) cladding.
