Abstract: Background

Blanket is an important component of China fusion engineering test reactor (CFETR). A large amount of heat inside the blanket needs to bring coolant to the outside of the Tokamak device.


This study aims to design the channel of inboard (IB) and outboard (OB) back supporting structure (BSS) to suitable for multiple operating conditions.


The thermal analyses for BSS under four working conditions were performed by FLUENT, a computational fluid dynamics (CFD) software, which conducted by fluid-solid coupling finite element. The temperature distribution and the heat exchange of IB, OB BSS under 200 MW, 500 MW, 1 GW and 1.5 GW conditions were analyzed.


The temperature distribution of the BSS, the heat exchange of the internal fluid and the average temperature change of the fluid were obtained under four working conditions.


The maximum temperature of the IB BSS and the OB BSS is less than the allowable temperature of the structural material; the average temperature change of the coolant on the IB and OB channels is consistent with the blanket outlet and inlet.

Key words: Blanket back supporting structure, Channel, Thermal analysis
