CARR控制棒驱动机构堆外调试试验

Out of Pile Commissioning Test of CARR Control Rod Driving Mechanism

中国先进研究堆(CARR)控制棒由磁力驱动。为进行CARR控制棒堆外调试试验,建造了模拟CARR热工水力条件的试验回路。试验中发现驱动机构存在一些问题,提出改进建议,得到CARR工程部和设计者认可。对驱动机构进行了一些改进,试验测量了线圈温度、落棒时间、极限流量和极限载荷等重要参数,试验证明经改进的控制棒驱动机构达到了设计要求。

China Advanced Research Reactor （CARR） control rods are driven by the magnetic force produced by electrical coils. An out of pile testing loop was specially constructed to simulate CARR thermal-hydraulic conditions for the test. Some problems were found during the experiment, and several proposals of improvement were offered for the modification of the driving mechanism and accepted by the CARR engineering department and the designer. The modification to the driving mechanism was implemented, and the important parameters were measured, such as the balance temperature of the coils, the rod drop time, the coolant flow limit, and the load limit. The results show that the modified control rod driving mechanism meets design requirements.
