Popis:	U(Mo) particles are obtained by centrifugal atomisation or by mechanical grinding fabrication processes and display microstructures which strongly influence the gas retention efficiency and consequently the behaviour of the fuel. Moreover, during fuel plate fabrication, a partial decomposition of the γ-U(Mo) phase toward the α-U and U2Mo phases can occur and is supposed to influence also the irradiation behaviour of the fuel. In situ X-ray and neutron diffraction experiments have been performed in order to study the γ-U(Mo) phase decomposition for two types of powders produced by the atomisation and the grinding routes. The present study allows assessing differences between these powders, in terms of γ-U(Mo) phase decomposition kinetics and mechanisms.
