Suppose India has a target of producing by 2000 A.D., 100,000 MW of electric power , 10 percent of which is to be obtained from nuclear power plants. Suppose we are given that, on average the efficiency of utilisation (i.e., conversion to electric energy) of thermal energy porduced in a reactor is `25 %`. How much amount of fissionable uranium would our country need per year at the turn of this century ? Take the heat energy per fission of `U^(235)` to be about 200 MeV. Avogadro's Number `N = 6.023 xx 10^(23) mol^(-1)`.
