Question

It is proposed to use the nuclear fusion reaction
$_{1} H^{2} +_{1} H^{2} \to_{2} H e^{4}$
in a nuclear reactor with an electrical power rating of $200 M W$ . If the energy from the above reaction is used with $25$ percent efficiency in the reactor, how many grams of deuterium fuel will be needed per day? (The masses of $_{1} H^{2}$ and $_{2} H e^{4}$ are $2.0141 a m u$ and $4.0026 a m u$ respectively.)
