摘要
安注箱是一种在核电站发生事故时向事故设备注射冷却水的先进设备.它对缓解核反应堆冷却水损失事故非常有利.本文在国外已有的新型安注箱设计基础上提出了一个原理性模型进行理论分析和数值模拟,以确认其注水特性.研究表明,对于所研究的原理性模型采用多尺度网格进行数值计算,可以得到能够满足核反应堆实际运行需求的水流量曲线。
The advanced accumulator is used in the nuclear power station and plays an important role in a loss-of-coolant accident （LOCA）. In this paper, a prototype model of the advanced accumulator based on the existing ones abroad was proposed and studied by using numerical simulation. The results show that for the proposed model the required variation pattern of the water flow rate with time can be obtained by using multi-scale mesh.
