Problem

1\,\mathrm{GW_e}

light-water reactor has a thermal power

P_{\rm th} = 3.0\,\mathrm{GW}

, runs at a capacity factor

\mathrm{CF} = 0.90

, and discharges its fuel at a burn-up

B = 60\,\mathrm{GW\,d\,t^{-1}}

. Find the mass of heavy-metal fuel that must be loaded (and, at equilibrium, discharged) each calendar year.
