The paper presents simulation results for the generation and evolution of defects in titanium targets of pulse neutron sources during their operation. Two approaches are compared: the explicit description of atomic diffusion on a rigid lattice and solution of a system of kinetic equations of the cluster dynamics. The kinetic Monte Carlo method is used in the both approaches. The time dependencies have been obtained for the concentrations of point defects and their aggregates, the size distribution of aggregates has been constructed.Keywords: radiation damage, the kinetic Monte Carlo method, cluster dynamics, SPPARKS program package.
