针对中国先进研究堆(CARR)工程调试C阶段过程中发生的安全棒意外落棒事件进行分析,其原因为:安全棒驱动机构回路中电磁阀因长时间工作引发烧损失效。为解决该安全隐患,对CARR安全棒驱动机构进行改进设计,提出“水力
Analysis of the accidental drop bar accident occurred during the C phase of China National Advanced Research Reactor (CARR) commissioning was as follows: The solenoid valve in the circuit of the safety rod drive mechanism caused the burning failure due to prolonged working hours. In order to solve the potential safety hazard, the CARR safety rod drive mechanism was improved and put forward ”Hydraulic
