Problem

A reactor burns

0.50\,\text{kg}

of pure

^{235}\text{U}

. Each fission releases

200\,\text{MeV}

, but neutrinos carry away

12\%

of this energy, making it unavailable for practical use. The usable energy obtained from the fuel is closest to a)

3.0\times10^{13}\,\text{J}

3.6\times10^{13}\,\text{J}

3.6\times10^{14}\,\text{J}

4.5\times10^{13}\,\text{J}
