Problem

During each fusion reaction between a deuterium nucleus (

A=2

) and a tritium nucleus (

A=3

), an energy of

17.6\,\text{MeV}

is released. Calculate the total mass of the D–T mixture that must undergo fusion to supply a constant power output of

5.0\,\text{GW}

for

1\,\text{h}

. (Assume one reaction consumes one deuterium and one tritium nucleus. Take

N_A = 6.02\times10^{23}\,\text{mol}^{-1}

1\,\text{u}=1.66\times10^{-27}\,\text{kg}

1\,\text{eV}=1.6\times10^{-19}\,\text{J}
