In a reactor, $2 \mathrm{kg}$ of ${}_{92}\mathrm{U}^{235}$ fuel is fully used up in $30$ days. The energy released fission is $200 \mathrm{MeV}$. Given that the Avogadro number, $\mathrm{N}=6.023\times {10}^{26}$ per kilo mole and $1 \mathrm{eV}=1.6\times {10}^{-19} \mathrm{J}$. The power output of the reactor is close to:
