A fuel element in nuclear reactors generally consists of fuel pellets, gaseous gap and cladding. Normally the pellets and cladding are coaxial. In this case; heat conduction equation in the fuel element is two dimensional, independent on angle (θ). Certainly elimination of gaseous gap in one direction (eccentricity of fuel pellets), will increase cladding and coolant temperature at the same direction. In this work, three dimensional analytical and numerical steady state heat transfer behavior in eccentric fuel element were studied to determine maximum temperature of fuel pellets, cladding, and coolant. Good agreement between analytical and numerical results was obtained. It is concluded that because of eccentricity of fuel element, melting of cladding and boiling in coolant will not occur.
