Progress on CFETR physics and engineering

Magnetic confinement fusion is an approach to generating thermonuclear fusion power that uses magnetic fields to confine the deuterium and tritium fuel in the form of a plasma. It is considered promising to completely solve the energy problems. China Fusion Engineering Test Reactor (CFETR) is the next Tokamak device in the roadmap to develop fusion energy in China. Two phases of CFETR have been proposed: Phase I focus on a fusion power of 200 MW and steady-state operation with tritium self-sufficiency. Phase II emphasizes a fusion power of 1000 MW and DEMO validation. CFETR will address the physical and engineering challenge that exist between ITER and DEMO, such as D-T steady-state operation, tritium breeding and self-sufficiency, and material that could withstand high heat load and neutron irradiation. This will lay a solid foundation for the independent construction of fusion power stations around 2050 in China.
