Abstract
There is proposed for the final storage of radioactive wastes a container made of an uranium alloy which compared to known containers made of uranium is less susceptible to corrosion and does not show any anisotropic thermal expansion at high temperatures. For this purpose, there is alloyed with uranium, which is preferably depleted, 5 to 15 wt. % molybdenum, 2 to 15 wt. % copper, 1 to 5 wt. % zirconium, 0.5 to 5 wt. % chromium, 0.5 to 2 wt. % nickel, 0.5 to 1.5 wt. % niobium, and 0 to 5 wt. % iron with the proviso that the total content of the alloying metals is 10 to 16% and the total of chromium, nickel, and niobium is at least 1.5%.
