First steps of the overall integration design of CFETR

The China Fusion Engineering Test Reactor (CFETR), which is a planned next-step fusion device under engineering design in China now, aims at bridging the gap between ITER and DEMO. As a reactor level device, CFETR will have dozens of complex systems and millions of components and parts. These systems/components shall be consistent with each other in such aspects as function, dimension and interface. The consistency among different systems for CFETR is assured through a dedicated task force of overall integration design, which defines the key engineering parameters of the CFETR tokamak main machine based on the physical design and the CAD rules guiding the mechanical design. The overall integration design also manages the interfaces between the main systems/components in the tokamak machine.
