Irradiation Behavior of Bonded Structures: Impact of Swelling-Creep-Stress Relationship

Abstract

Radiation damage will be a major key point in the design of the many duplex components in fusion reactors. There is a substantial amount of available data showing that stress plays a major role in die onset, and possibly the rate, of void growth in austenitic stainless steels. There is also a strong support for models which predict a coupling of swelling and creep through the stress environment A parametric study for the stress-enhanced swelling and its connection to creep is conducted for a typical fusion power demonstration reactor.
