运用零维模型评估了流动液态锂幕帘作为聚变实验增殖堆工程概要设计 (FEB-E) 第一壁对聚变等离子体的影响。得到了锂液帘工作温度对堆芯有效平均等离子体电荷?Zeff?,燃料稀释以及聚变功率之间的关系。表明在正常工作情况下,液态锂的蒸发对?Zeff?的影响不是很严重,但对燃料稀释和聚变功率的影响却较为敏感。作为一个例子,对较高功率密度的反剪切位形聚变实验增殖堆FEB-E设计方案 II,计算了液帘的流速与它表面最大温升的关系,结果表明:即便0.5m/s的低速流动液帘第一壁, 蒸发对聚变等离子体的影响也甚微。
The zero-dimensional model was used to evaluate the effect of flowing liquid lithium curtain as the first wall of Fusion Experimental Breeder Reactor Design (FEB-E) on fusion plasma. The relationship between the working temperature of lithium liquid curtain and the effective average plasma charge of the core? Zeff ?, fuel dilution and fusion power was obtained. It shows that under normal operating conditions, the influence of liquid lithium evaporation on Zeff? Is not very serious, but it is more sensitive to the influence of fuel dilution and fusion power. As an example, for the high power density anti-shear shape fusion experimental breeder reactor FEB-E design II, the relationship between the flow rate of the liquid curtain and the maximum temperature rise on the surface of the liquid curtain is calculated. The results show that even if the flow rate of 0.5m / s Low-velocity liquid curtain first wall, the impact of evaporation on the fusion plasma is also very small.
