Blowers move helium gas through the reactor and over the pebbles, where nuclear fission releases large amounts of energy, heating up the helium.

There are some characteristics of a nuclear fission reactor that will be common to every nuclear fission reactor.

Thermoelectric coupling uses heat from the decay of a radioactive fuel (as opposed to the full-scale nuclear fission which powers a reactor on Earth) as its energy source.

ECONOMIST: A more efficient way to make electricity in spacecraft

Rather than create electricity by heating water and turning a turbine, Wilson's new reactor would use nuclear fission to produce energy from molten salt.
