| 摘 要： | 针对 10 MW高温气冷堆 (HTR- 10 )控制棒传动机构可能出现的事故隐患——链条断裂、联轴器键损坏等现象 ,建立了其传动机构的理论分析模型 ,进行了能量分析。结果表明 :缓冲器吸收能力与联轴器强度的匹配问题是联轴器可能出现损坏的主要原因 ;温度的升高降低了涡流阻尼力 ,造成缓冲器吸收能力与联轴器强度的不匹配 ;缓冲器的变形量与作用在联轴器上的作用力有关。为 HTR- 10控制棒传动机构的设计提供了理论依据

| Abstract: | This paper presents a theoretical model for the control rod drive mechanism for the 10MW High Temperature Gas Cooled Reactor (HTR 10) and analyzes accidents which may occur in the drive mechanism, for example, chain break, coupling damage and other damage scenarios. The results show that the matching problem between buffer capability and coupling strength is the main reason for coupling damage; increased temperatures would reduce eddy damping and cause a mismatch between buffer capability and coupling strength; and the displacement of the buffer spring will affect the coupling force. The results provide a theoretical basis for the design of the control rod drive mechanism for HTR 10. |
