Taking into account the effect of nonequilibrium point defects, analytic expressions for the rates of absorption and emission of atoms at the particle-matrix interface have been derived. For the particle size distribution function under irradiation, a kinetic equation with the cascade term has been constructed and its stationary solution in the analytical form has been found and studied. An appropriate choice of the model parameters results into a good agreement with the experimental data [A. Certain et al. Journal of Nuclear Materіals. 434 (2013) 311] for the size distribution function of oxide nanoparticles in a 14YWT steel after irradiation with 5 MeV nickel ions up to the dose of 100 displacements per atom at temperatures of 600, 450, 300 and 100 C and after nucleation at 850 C without irradiation.
