A 20 cm diameter cylindrical solid pellet of a nuclear fuel with density 6000 kg/m³ and conductivity of 300 W/(m K) generates heat by nuclear fission at a spatially uniform rate of 104 W/kg. The heat from the fuel pellet is transferred to the surrounding coolant by convection such that the pellet wall temperature remains constant at 300 °C. Neglecting the axial and azimuthal dependence, the maximum temperature (in °C) in the pellet at steady state is_______ (rounded off to the nearest integer).
