择要: 福岛变乱当前,乏燃料池塘的平安性遭到越来越多的注重。因而,有须要对喷淋冷却的影响要素展开实行研讨。

本文树立了职称论文发布一套乏燃料池塘喷淋冷却实行安装,用5×5电加热棒束模仿核电厂乏燃料池塘中的一组乏燃料棒,失掉差别功率程度下维持包壳温度在300℃的最小喷淋流量。别的,改动喷嘴型号,探求差别喷淋颗粒度对乏燃料池塘喷淋冷却结果的影响。实行后果标明,喷淋水颗粒度关于最小喷淋流量有较大影响。

要害词: 核平安;乏燃料池塘;喷淋冷却;流量;颗粒度

Abstract: Safety of spent fuel pool has been paid much attention since Fukushima nuclear accident. So, it’s necessary to research influencing factors of spray cooling. A set of spray cooling experimental device for spent fuel pool is built. Electrically heated rods 5×5 are used to simulate spent fuel rods of spent fuel pool in Nuclear Power Plant to get different minimum spray flows when temperature of clad is kept in 300℃. Besides, change nozzle types to gain different granularity of spray water to research its influences on spray cooling effects for spent fuel pool. The results show that granularity of spray water has great effect on minimum spray flow.
Keywords: Nuclear safety; Spent fuel pool; Spray cooling; Fluid shape; Particle size
