The reactor produces power or . The reactor is to function for . Therefore, total energy which the reactor will supply in is
But since the efficiency of the reactor is only , therefore actual energy needed is 10 times of it or . One uranium atom liberates of energy or or of energy. So, number of uranium atoms needed are
or number of kg-moles of uranium needed are
Hence, total mass of uranium required is
