摘要

The candidate structural materials for next generation advanced nuclear systems,such as fusion reactors and ADS(accelerator driven subcritical systems),will suffer from the irradiation by neutrons with higher energy and flux,especially.Resulting in higher displacement damage and higher concentration gas atoms from nuclear transmutation introduced in the materials.Therefore,the synergy effects of gas atoms and displacement damage have been one of the importance problems for evaluating and developing the materials.To provide a basic understanding on this problem in SIMP steel which is considered as a potential candidate structural material for the future advanced nuclear reactors,the effect of hydrogen on voids(or bubbles)nucleation in SIMP pre-implanted by He at 550℃has been investigated by TEM.
