分流器是聚变堆核电站的重要部件,其主要功能是去除反应灰和侵蚀粒子并带走热,因而对分流器材料提出了苛刻要求,如高导热性、高熔点、高断裂韧性、抗溅射、低的热膨胀系数和低活性等。目前,钨是惟一有希望的选材。为了控制分流器表面温度,在其背部采用了氦冷却系统,有两种不同?
Shunt is an important part of the fusion reactor nuclear power plant, its main function is to remove the reaction ash and the erosion of particles and take away the heat, and thus made the shunt material demanding requirements, such as high thermal conductivity, high melting point, high fracture toughness, anti-sputtering , Low coefficient of thermal expansion and low activity. At present, tungsten is the only promising material. In order to control the surface temperature of the splitter, helium cooling system is used on the back of the splitter. There are two kinds of difference?
