Suppose India had a target of producing by 2020 AD, 200,000 MW of electric power, ten percent of which was to be obtained from nuclear power plant. Suppose we are given that, on an average, the efficiency of utilisation (i.e., conversion to electric energy) of thermal energy produced in a reactor was 25%. How much amount of fissionable uranium did our country need per year by 2000 ? Take the heat energy per fission of  to be about 200 MeV. Avogadro's number .  

Answer:

Total power target = 200000 MW Nuclear power target Total power generated Total energy required for the year 2020, is (2020 is a leap year) Now 1 fission of produces 200 MeV of energy Number of fission required for the generation of energy E Now  nuclei of  have mass = 235 g. Mass required to produce 7.90 x 1028 nuclei
