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.
