Wall stabilization in a possible high-temperature gas-core fission reactor

Abstract

It is investigated if graphite as wall material in a gas-core reactor is compatible with a gas mixture consisting of UF6 and carbon fluorine compounds at high temperatures. A possibility for non-corrosive operation exists at temperatures ranging from 2000 to 2500 K at pressures of about 30 atm, introducing a mixture of UF6 and about 20 to 30 mole % C₂F₂ or C₂F₄ Another possibility is to introduce UF₄ as an aerosol in CF₄ as a carrier gas. For the latter case a flow-sheet is presented, indicating the possibility of a non-proliferation fission reactor.
