After fast neutron irradiation, uranium-plutonium nitride U 0.8 Pu 0.2 N is shown to acquire a com plex structure consisting of a solid solution that is based on the nitrides of uranium, plutonium, americium, neptunium, zirconium, yttrium, and lanthanides and contains condensed phases U 2 N 3 , CeRu 2 , BaTe, Ba 3 N 2 , CsI, Sr 3 N 2 , LaSe, metallic molybdenum, technetium, and U(Ru, Rh, Pd) 3 intermetallics. The con tents and compositions of these phases are calculated at a temperature of 900 K and a burn up fraction up to 14% (U + Pu). The change in the composition of the irradiated uranium-plutonium nitride is studied during the electron decay of metallic radionuclides. The kinetics of transformation of U 103 Ru 3 , 137 CsI, 140 Ba 3 N 2 , and 241 PuN is calculated.
