【摘要】 利用阶跃注入的扰动-响应技术,使用模拟介质,在模拟装置上,进行硼溶液注入反应堆堆芯后混合、迁移研究。实验结果表明,注入喷嘴所在的下联箱可以近似成一阶惯性环节,硼水混合物流经元件盒入口节流段,进入元件盒后的流动是迁移运动。本文还给出了硼水初始混合份额η的定义和数据关联后的准则方程。更多还原

【Abstract】 A pulse injection stimulus-response technique to study the boron mixing and transport performance after boron-loaded liquid was injected into the reactor core is described. The experiment was carried out in a simulation device. The simulation medium was used. The experimental results show that the lower plenum in where the injection point located can be simplified to one scale iner-tial unit and the movement of boron mixture was only transported after it had entered into the fuel elements. The definition of boron initiative mixing fraction T] is also given. By using relating data a dimensionless equation is obtained.更多还原
