摘要:

为提高偏滤器的抗中子辐照能力,兼顾高热承载能力和聚变堆经济性的需要,提出了基于熔盐冷却(MSC)的偏滤器靶板结构设计。它采用FLiNaK作为冷却剂,钨镧合金为热沉材料,钨为第一壁材料。通过数值计算评估了靶板的热负荷承载能力,并完成了偏滤器冷却剂回路设计,优化了偏滤器各模块之间的流量分配。此MSC偏滤器靶板设计可以有效去除10~15MW•m-2热负荷,为适应未来聚变堆偏滤器靶板发展的需要提供了一种设计解决方案。

Abstract:

In order to design a divertor with resistance to neutron irradiation, achieve a high heat transfer capacity and improve the efficiency of fusion plant, a molten-salt-cooled (MSC) divertor target is proposed. The MSC divertor target adopts FLiNaK as the coolant, and tungsten alloy as heat sink material, and tungsten as first wall material. The heat transfer capacity was evaluated with numerical calculation, and the cooling system of divertor was designed to optimize flux distribution among different modules. The MSC divertor target design can effectively withstand a steady heat flux of 10~15MW•m-2, and will provide a design solution of the development need of a divertor target in further fusion reactor.

Key words: Fusion reactor, Divertor target, Molten-salt-cooled, Thermo-hydraulic, Thermo-mechanical
