And then of course as part of the absorption we have a fission cross section which, as I said earlier, is what we want to focus on so we can make some power and some heat.

Nuclear power is produced by harnessing the heat produced by the splitting of atoms inside uranium - a process known as fission.

In operation since the early 1970s, Japan's Fukushima Daiichi nuclear plant USES six boiling water reactors, which rely on uranium nuclear fission to generate heat.
