POWDER OF AN ALLOY BASED ON URANIUM AND ON MOLYBDENUM USEFUL FOR MANUFACTURING NUCLEAR FUELS AND TARGETS INTENDED FOR PRODUCING RADIOISOTOPES

摘要

The invention relates to a powder of an alloy based on uranium and molybdenum in a metastable γ phase, which is formed of particles which have an elongation index at least equal to 1.1, a non-zero closed porosity value and which are composed of grains having a molybdenum content, for which the variations within the same grain are of at most 1% by mass.;It also relates to a method allowing preparation of this alloy powder as well as to the use of said powder for manufacturing nuclear fuels and targets for producing radioisotopes.;Applications: Manufacturing of nuclear fuels, notably for experimental nuclear reactors; manufacturing of targets for producing radioisotopes, notably for the medical industry.
