摘要
氦气冷却系统是ITER中国液态锂铅实验包层模块(DFLL-TBM)在ITER装置内进行实验的重要辅助系统。根据ITER运行时的热工条件、安全要求、空间要求,分析了DFLL-TBM氦气冷却系统的功能,确定氦气冷却系统的设计原则和要求,在此基础上给出氦气冷却系统的初步设计方案和设备布置。该氦气系统的特点体现在:双功能,即有宽的裕量满足SLL-TBM和DLL-TBM实验;两条氦气回路共享压力控制单元和氦气净化子系统;旁路设计调节TBM和热交换器氦气的出口温度。
The helium cooling system is an important ancillary system of the dual-functional lithium lead test blanket module （DFLL-TBM） for ITER. Based on thermal hydraulic conditions, safety and space requirements for ITER, the function analysis and the design principles, the preliminary design and the components＇ arrangement of the helium cooling system are proposed for DFLL-TBM. The features of the system is that the equipment specification has wide margin for DLL -TBM and SLL-TBM test, i. e. dual function, and that both helium loops share pressure control unit and helium coolant purification sub-system, and that bypass design can adjust outlet temperature of helium for the DFLL-TBM and the thermal exchanger.
