    Abstract

    The theory of cavity nucleation in irradiated metals has been modified to include three important effects: (1) non-ideality of the inert gas in cavities, (2) a linearly increasing helium concentration with dose, and (3) nucleation of cavities on approximately equilibrium bubbles of any size. Calculations using the improved model to predict cavity density and size distribution are reported for simulated fast neutron and dual-ion irradiation experiments.
