Abstract
Isotopically enriched helium-4, that is, helium-4 which is low in helium-3, is useful as a nuclear reactor coolant. It is produced from liquefied natural gas source helium by distilling helium-3 therefrom. The coolant is preferably enriched in hydrogen up to about 6 percent by volume to thereby improve the heat transfer characteristics of the coolant, and to reduce the power requirements for circulation of the coolant.
