USE OF THE FULLY DYNAMIC RATE THEORY TO PREDICT VOID GROWTH IN METALS

A Fully Dynamic Rate Theory (FDRT) has been used in the computer code TRANSWELL to analyze the response of metals during steady-state and pulsed irradiations. This paper correlates the FDRT with experimental data on void growth in metals. It is shown that the theory is successful in predicting the swelling behavior of different metals over a wide range of temperatures, dose rates, bombarding particles and irradiation time structures. Swelling of 316 stainless steel, Aluminum and Nickel bombarded with heavy ions, neutrons, and electrons at dose rates varying from 10** minus **6 to 10** minus **1 dpa/second is studied for both steady-state and pulsed irradations.
