Abstract

Understanding nuclear materials response in extreme environments, such as intense irradiation and high temperature in fusion reactors and advanced fission reactors, is significant in designing advanced nuclear energy systems. Recently, a nuclear material irradiation system has been installed and in service on the beam line of 4.5 MV electrostatic accelerator. The energy range of proton or helium ion accelerated will be from 0.7~3.5 MeV, and the ion current will be up to 10 A. The system will consist of a vacuum chamber combined with heating controlling, which can achieve the irradiation under 1 000 ℃. In addition, by coupling 26 MV tandem accelerator and 4.5 MV single end electrostatic accelerator, a double beam irradiation system has been assembledand tested to study the synergistic effects of displacement damage, helium or hydrogen irradiation effects on microstructural changes of materials, as the experimental simulation of irradiation damage in reactors
