C) Easily we can conclude that the efficiency of nuclear reactors are very much higher than the coal. Very few amount of Uranium is needed to produce a large quantity of energy. It is evident from the above calculations also. Here, 25 gram of Uranium produces same amount of energy obtained by combustion of 60000 kg of coal. So the efficiency is much higher in nuclear reactors than coal.

d) Nuclear fusion is different than nuclear fission. In the fusion, we fuse two or more light weight molecules to a heavyweight molecules. In this process, the mass is lost and the equivalent amount of energy is obtained. But the fusion process itself needs high amount of energy to happen. So generally nuclear fission is done first to occur the nuclear fusion. But nuclear fission is very dangerous to set up in a laboratory. The radioactive waste and the neutron radiation damage are the serious problems. Also the proper coolant is mandatory to convert the thermal energy to the mechanical energy. The moderators are also required to control the nuclear process. All these factors are playing essential roles as the barrier in this process.
