研究堆控制棒通道冷却剂流动阻力特性实验研究

可移动线圈电磁驱动机构是一种新型的控制棒驱动机构,应用于研究堆.控制棒、跟随组件等在控制棒通道内上下移动,同时冷却剂冲刷控制棒和跟随组件.所以控制棒通道内的流体阻力特性直接关系到整个堆芯的流量分配和控制棒跟随组件是否能得到足够的冷却.在进行了控制棒通道的阻力特性实验后,得到了多种运行工况下阻力与流速、棒位等参数的关系,以及影响驱动线阻力特性的因素.

Experimental study on the coolant flow resistance of control rod channel in research reactor

Electromagnetic movable coil control rod drive mechanism is a new type one, and it is used in the research reactor. Control rods, the following discreteness, and some other components are moving in the control rod channel and at the same time the coolant scours the control rods and the following discreteness. So the flow resistance in the channel directly determines the flux distribution in the core of the reactor and whether the following discreteness can be adequately cooled. Through the data of flow resistance experiment on this control rod channel, this paper obtained the relationship between the flow resistance and many parameters such as flow speed, the position of the control rod, and analyzed the causation of the different flow resistances.
