It is proposed to use the nuclear fusion reaction:

\({ }_{1} \mathrm{H}^{2}+{ }_{1} \mathrm{H}^{2} \rightarrow{ }_{2} \mathrm{He}^{4}\)

in a nuclear reactor of 200 MW rating. If the energy from the above reaction is used with a 25% efficiency in the reactor, how many grams of deuterium fuel will be needed per day? (The masses of \({ }_{1} \mathrm{H}^{2}\) and \({ }_{2} \mathrm{He}^{4}\) are 2.0141 atomic mass unit and 4.0026 atomic mass unit respectively)
