“…Irradiation tests of U-Mo/Al dispersion fuel have shown that radiation-induced microstructural changes significantly influence the fuel's performance. The presence of interaction layers at the interfaces of the U-Mo particles and Al matrix during irradiation is one of the most challenging issues in the development of U-Mo/Al dispersion fuel [3]. Since the Al matrix is consumed by the interaction, the thermal conductivity of U-Mo/Al dispersion fuel decreases and the fuel temperature increases.…”

“…La utilización de U de bajo enriquecimiento en aleaciones U(Mo) en fase γU se está estudiando para su empleo como combustible nuclear tipo disperso o monolítico para la conversión de los reactores de investigación y producción de radioisótopos de alto flujo neutrónico [1,2]. En esta aleación, la adición de 7 a 10% en peso de Mo se utiliza para mantener, en condición metaestable a temperatura ambiente, la fase γU que presenta la mejor respuesta bajo irradiación [1][2][3].…”

“…Mo has high solubility in -U that allows for fuel customization, and the alloy satisfies the fissile-U densities required by the RERTR program. Extensive studies and characterization of UMo alloys have been carried out to develop an understanding of the phase equilibria , kinetics [45][46][47][48][49][50][51][52], mechanical properties [53][54][55][56][57], thermodynamics [58][59][60][61][62] and irradiation behavior [63][64][65][66][67][68][69][70][71][72][73] of this system. In early studies, Pfeil [22], Saller et al [23][24][25], Ivanov et al [29,34], Carrera et al [26] and Dwight et al [27] detailed the -U ( -U + -U 2 Mo) decomposition that takes place below 573°C.…”
