Cluster dynamics simulation of point defect clusters in neutron irradiated pure iron

The effect of the size dependence of production rate of point defect clusters is taken into account in the cluster dynamics modeling of the simultaneous formation of vacancy clusters and self-interstitial atom clusters in neutron irradiated pure iron. The calibration of material parameters has been carried out. The correspondence between small angle neutron scattering, transmission electron microscopy and positron annihilation spectroscopy and cluster dynamics data is studied.
