It is proposed to use the nuclear fusion reaction \[_{1}{{H}^{2}}{{+}_{1}}{{H}^{2}}\to 2H{{e}^{4}}\] in a nuclear reactor of 200 MW rating. If the energy from the above reaction is used with 25% efficiency in the reactor, how many gram of deuterium fuel will be needed per day? (The masses of \[_{1}{{H}^{2}}\] and \[_{2}H{{e}^{4}}\] are 2.0141 amu and 4.0026 amu respectively).

Answer:

120
