Storage of Hydrogen Isotopes in Uranium Alloys

Abstract

AbstractHydrogen absorption-desorption properties of some uranium-rich alloys were studied to develop an advanced material for temporary tritium storage. The characteristics of U-33.3at%Zr were analogous to those of U-69.7at%Zr, while the durability to powdering was reduced according to a decrease of zirconium content. The U-5.7at%Al exhibited a similar behavior to that of pure uranium including powdering to much extent, though a slight decrease in decomposition pressure was observed. The U-25at%Si showed very small capacity of hydrogen in spite of the existence of uranium phase in this alloy.
