  The original fuel is deuterium, which is absurdly abundant on Earth. Pure deuterium fusion results in half helium-3, and half tritium which decays to helium-3 with a 12 year half-life. Then their main reaction is D-He3. The D-D reaction is less energetic and produces a neutron, and the D-He3 reaction doesn't produce a neutron. The combined reaction would release about five percent of its total energy as neutron radiation. The neutrons from D-D are about as energetic as fission neutrons, rather than the extremely high energy of D-T fusion neutrons. They'll never run out of fuel; there's enough deuterium in your morning shower to provide all your energy needs for a year. But the need to breed He3 will put a limit on how fast they can possibly scale up. It could be that manufacturing will be slower than that anyway though.

    Thanks for the insight. I remember it being like the raw ingredients were plentiful, but the main reaction ingredients were not.
