The research activity of radiation damage of reactor materials in IMP was launched in 1980s to meet the demand of the R&D of structural materials for the Fission/Fusion Hybrid Reactor program in China. The Energy Materials Group, since her foundation in 2011, has been dedicated to pushing forward the radiation damage research by utilizing high-energy ion accelerators in IMP.
Thanks to the fast development of the nuclear energy field in China, the group joined several national projects including the National Magnetic Confinement Program, the Chinese Prototype Fast Reactor Program, and the China Nuclear Reactor Life Extension Program. The group was also sponsored by the National Science Foundation of China.
Our research activity covers fundamental studies on the radiation damage evolution in advanced nuclear reactor materials including ODS ferritic steels and SiCf/SiC composites, and evaluation of key materials for Gen III and Gen IV reactors. A specialized irradiation terminal was setup at HIRFL for material irradiation.
Now the group has 8 staffs, 1 postdoc researchers and 4 postgraduate students. We sincerely welcome industrious young people to join us.

The Energy Materials Group has been dedicated to pushing forward the radiation damage research of advanced nuclear reactors. It includes the setup of facilities and methods for the evaluation of material performance under intensive irradiation condition, the identification of mechanisms underlying particle irradiation, the modeling of damage evolution. The ongoing studies in our group are listed as follows.
1. Radiation embrittlement of structural materials candidate to fast and fusion reactors;
2. High throughput technology for the evaluation of life extension of RPV steels;
3. Mechanisms underlying radiation response of the FeCrAl-base ODS ferritic steel and SiCf/SiC composites
About 40 papers were published in refereed journals (in English) while 4 patents were granted since 2011. Papers representing our research progress are listed as follows in two categories.
