FFR实验快堆控制棒驱动机构样机设计(Ⅰ型)

DESIGN OF THE CONTROL ROD DRIVE MECHANISM PROTOTYPE FOR THE FFR (I TYPE)

文章叙述了FFR实验快堆控制棒驱动机构样机的主要功能、设计准则和要求、主要技术参数,介绍了控制棒驱动机构的8个主要部件的结构和基本数据。主要部件是主驱动系统、快速释放系统、缓冲系统、抓手系统、密封系统、位置指示系统、弹性补偿装置和锁紧装置。最后叙述了整机的结构特点和设计背景。

The paper describes main function design criteria and requirement, main tech-nical parameters of the control rod drive mechanism prototype for the FFR atfirst. Then describes in detail the structure and parameters of eight basiccomponents, i.e. the main drive system, the fast release system, thedamping system,the gripper system, the seal system, position indication system, the spring compensationdevice and the mechanical lock device. Finally, the structure features and thedesign backgroundes are described.
