ABSTRACT
In U-Mo/Al dispersion fuel under irradiation a (U,Mo)Alx interaction layer is formed along with the pores, which contain gas fission products. The gas pores are formed in fuel particles, the (U,Mo)Alx layer and the aluminum matrix, that is near the (U,Mo)Alx layer. A structure of pores is mainly studied by using optical and scanning electron microscopy to allow an examination of pores with sizes better than tenth parts of microns. In this paper the influence of burn up and isochronal annealing at temperatures ranging from 150 to 580 оС on changes in the substructure characteristics of the U-Mo/Al dispersion fuel is investigated. The investigations were conducted by using the small angle neutron scattering that allows to study the substructure characteristics of the fuel in the range from 1 to 50 nm.
