The coolant gas contains an alkali metal vapour and a barium oxide suspension to enhance ionization. The steam generator heat exchanger and the M.H.D. generator are mounted within the reactor pressure vessel together with the gas circulator. The reactor coolant gas also cools the core reflector. The uranium carbide fuel rods transfer heat directly to either the hot junctions of the thermoelectric devices or to the emitter in the thermionic case.
