【摘要】：日本福岛核电站事故发生后,乏燃料水池失去补水后的冷却问题引发了大家的关注。本实验设计了一套非能动乏燃料水池喷淋系统,并对其喷淋冷却效果进行了验证。实验用3×3棒束电加热棒模拟核电厂乏燃料水池中的一组乏燃料组件。本实验在冷态下对其喷淋后分析其喷淋流型,与单根棒的喷淋流行进行对比,在加热状态下分析喷淋冷却的冷却效果。探究不同喷淋流量与喷淋角度对乏燃料水池喷淋冷却效果的影响。
[Abstract]:After the accident of Fukushima nuclear power plant in Japan, the cooling problem of spent fuel pool after losing water has attracted much attention. In this experiment, a set of passive spent fuel pool spray system was designed. The effect of spray cooling was verified. A group of spent fuel assemblies in spent fuel pool of nuclear power plant were simulated with 3 脳 3 rod beam electric heating rod. The spray flow pattern was analyzed after spraying in cold state. The cooling effect of spray cooling was analyzed under heating condition, and the effect of different spray flow rate and spray angle on spray cooling effect of spent fuel tank was studied.
