— Fusion Reactor  Materials Division —


Controlled D-T fusion is a promising way to supply inexhaustible clean energy. Practical nuclear fusion engineering needs to confine plasmas using strong magnetic fields in a vacuum vessel, and the fusion energy should be extracted from steady plasma burning on the basis of self-sustained fuel breeding. This procedure involves Multi-field conditions, including high-temperature and high-density plasmas, high flux of 14MeV neutrons, high heat flux, corrosive liquids, complex electromagnetic fields, ultra-temperature gradients, high stresses, and so on. These conditions lead to extremely serious challenges for the materials used in a fusion reactor, thus should be solved before the application of practical nuclear fusion energy is achieved.


The Fusion Reactor Materials Division at SWIP aims at the R&D of key technologies for materials and relevant components to be used in fusion devices beyond ITER era. Through experimental research on advanced platforms and numerical simulations, and with support from extensive international & domestic collaborations, this division concentrates on the solution to essential requirements of key components in a fusion reactor. Main work focuses on the improvement of performance as well as lifetime of the component materials so as to create superior plasma burning, fuel cycle and strong electromagnetic field conditions, thus support the design and construction of nuclear island for fusion reactors in the future.


The work of this division will long-termly center on the concepts and materials of key components in fusion reactors, focusing on experimental studies and technology development while attaching great importance to materials database establishment and numerical simulation under collaboration framework. This division is able to fabricate various advanced materials, validate their properties, and promote the established technologies to be used in fusion engineering, eventually obtains different material options and applied forms to support design of different types of fusion reactors.


There are 1 professor of “The Recruitment Program of Global Experts”, 7 other professors, 6 associate professors and nearly 40 young talents and students in this division embedded with a ‘Plasma-Materials Interaction Research Center’. Members are engaged respectively in fusion blanket structural materials research, plasma-facing materials research, plasma-materials interaction research, liquid-metal MHD effects study, advanced magnet technology development, development of key technologies for irradiation testing, etc. In the recent years, lots of outstanding achievements have been obtained in following aspects: development of new tungsten-based materials and high heat flux testing, control of liquid-metal free-surface, development and creep study of vanadium alloys and ODS steels, and plasma-wall interaction in Tokamak. In addition, 2 engineering projects including ITER magnet support PA and HL-2M Tokamak divertor manufacturing are involved.
