分析了中国先进研究堆（CARR）在C阶段调试过程中发生的安全棒意外落棒事件，查找原因为：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“水力提升‐水力磁力保持式”安全棒驱动机构设计方案，使用Ansoft公司的有限元分析软件Maxwell对水力提升‐水力磁力保持式安全棒驱动机构磁路进行有限元分析，计算得到驱动机构的电磁场分布及电磁力的数值，计算结果表明，磁力保持装置产生电磁力可达到安全棒驱动线重量的2.12倍，具有一定的裕度。

The problem of safety rod accident dropped during C commissioning phase for China Advanced Research Reactor (CARR) was analyzed ,and the reason was that the solenoid valve in safety rod drive mechanism (SRDM ) driven loop was breakdown because of long‐playing work . To solve this safe hidden trouble , SRDM was rede‐signed ,and a new type of “hydro lifting‐hydro and electromagnetic holding”SRDM was presented ,using Ansoft Maxwell to make a finite element analysis on new SRDM , working out electromagnetic field distribution and electromagnetic force of new SRDM . The results show that the value of electromagnetic force produced by electromagnetic force holding unit reaches 2.12 times about the weight of safety rod drive line ,and it has some margins .
