摘　　要：２００ＭＷ核供热堆采用控制棒水力驱动系统作为控制棒驱动机构。该系统是以非能动系统为基础设计的，并实现了传动、导向一体化。通过时系统自身固有安全特性及设计安全特性、失压事故下控制棒不发生弹棒的机理以及系统引水管破断冷印剂总丧失量不会导致堆芯裸露的计算结果的分析，表明该系统具有良好的安全特性，在任何失效事故下都能保证反应堆的安全停堆，为具有固有安全特点的２００ＭＷ核供热堆提供了重要的技术支持。The hydraulic driving system of control rod is used as control rod drive mechanism in 200MW nuclear heating reactor . Design of this system is based on passive system, integrating drive and guide of control rod . This paper analyzes the inherent safety and the design safety of this system, with mechanism of control rod not ejecting when the pressure of pressure vessel is lost, and calculating result of core not exposing when the amount of coolant is drained by broken pipe. The results indicate that this system has good safety feature, and assures reactor safety un- der any accident conditions, providing important technology support for 200MW nuclear heating reactor with inherent Safetv feature.
