The invention relates to a powder of an alloy based on uranium and molybdenum in a metastable &#x3b3; 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 experiment nuclear reactors; manufacturing of targets for producing radioisotopes, notably for the medical industry.
