Auteur : Taillefer, Yves,Note :
A critical problem in designing an efficient coaxial-flow reactor is to keep the uranium gas from escaping through the nozzle with the hydrogen. The nuclear-light-bulb engine completely prevents this loss: the uranium gas is enclosed in a transparent shell, and heat transfer is entirely by radiation. Since the shell is comparatively cool, it does not melt as the radiation passes through it. The radiation is absorbed by the propellant hydrogen gas flowing around the "light bulb".
