In the 2011 nuclear accident at Fukushima, Japan, an earthquake-triggered tsunami wiped out emergency generators, leaving three reactors without a source of cooling water. Although safety systems shut down the reactors during the earthquake, radioactive decay continued to generate thermal energy at the rate of some $33 \mathrm{MW}$. In a desperate attempt to $\mathrm{cool}$ the reactors, operators used fire engines to pump seawater into the reactors. If $650 \mathrm{~m}^{3}$ of $10^{\circ} \mathrm{C}$ seawater were injected into a reactor, how long would it take that $33 \mathrm{MW}$ of thermal power to bring the water to the boiling point?
