ABSTRACT

The irradiation behavior of the interaction product in U-Mo/Al dispersion fuel during a pore formation resembles very closely that of an amorphous material, suggesting that the interaction product is amorphized and the structural instability of the interaction product is due to its amorphous character. However, no direct evidence as to whether it is amorphous or crystalline has been reported. Although extensive out-of-pile diffusion tests have been carried out to obtain metallurgical information of the interaction products, the interdiffusion behavior between U-Mo and Al is not fully understood and inconsistencies between out-of-pile and in-pile data still remain. In this paper, we analyzed all the available characterization results from both out-of-pile and in-pile tests to propose the most probable nature of the interaction product during irradiation and to establish the most consistent diffusion paths in the U-Mo-Al ternary system.
