摘　　要： 采用1:1轴向比例模拟实堆运行环境,开展模块式小型堆(ACP100)控制棒驱动机构(CRDM)的风冷性能热态试验。测定了正常运行时不同冷却风速下各线圈平衡温度、线圈断风后温度变化及电气性能,获得了驱动机构的最小风速、允许断风时间、极限断风性能等关键参数,为ACP100的驱动机构通风冷却系统设计和实堆运行提供重要的参考。 The thermal test study focusing on air cooling performance of the control rod drive mechanism （CRDM） for ACP100 is carried out in the environment of practical reactor operation condition, which is simulated as 1 ： 1. The balance temperature of the CRDM in different cooling air speed condition, the changing of the temperature after the cooling air broken off, and the electrical characteristics were measured. Some crucial data such as the minimum cooling velocity, the allowable time and the maximum performance without cooling were acquired. The test results provided an important reference for the cooling system design and operation of the small modular reactor ACP 100.
