In a homogeneous reactor, having a solution or suspension of fuel in heavy or light water, steam is produced by boiling and the gaseous fission products are removed from the steam by a current of a permanent gas. The gases are passed continuously through the reactor steam zone and the relative volumes of gas and steam are chosen so that the greater part of the fission products are retained by the gas and a relatively small part by the reactor core. The gas may be deuterium, helium, oxygen, hydrogen, nitrogen, neon, argon and the suspension fuels may be uranium and thorium oxides, while uranium sulphate may be used in solution.
