Description
The U-Zr-Er alloy is used in the nuclear fuel for the TRIGA reactors. The paper present the technological aspects of manufacturing of U-Zr-Er alloys by powder metallurgy. The basic steps are: hydriding of uranium, zirconium and erbium, blending, pressing and sintering. By hydriding the bulk metals can be easily transformed without supplemental contamination in powder. The blending process ensures a homogenous distribution of components. During the vacuum sintering process the metal hydrides are decomposed in metal and the hydrogen that is evacuated. The sintering at 1300 deg C results in densities higher then 95% DT. (author)
