【摘要】 核电站反应堆的启动、功率调节和安全停堆,由反应性控制装置操作完成。反应性控制装置的驱动机构所处工作环境复杂,作为非常关键的机械传动部件,直接控制中子吸收体在堆芯的位置,对其要求可靠性高,使用寿命长。压水堆以及新近发展起来的高温气冷堆等不同堆型的反应性控制装置驱动机构不尽相同,本文从压水堆、高温气冷堆等不同堆型反应性控制装置驱动机构的工作环境、机械传动原理、结构、性能、使用寿命等方面进行了分析比较。此外还基于反应性控制装置驱动机构的工作原理,并结合国内外在其设计和试验验证上的发展趋势,探讨了进一步提高改进、完善驱动机构结构及功能的方法与可行性。更多还原

【Abstract】 The startup,power regulation and safety shutdown of the nuclear reactor are operated by the reactivity control devices.Reactivity control drive mechanism is a key mechanical transmission component,which directly control the location of the neutron absorber in the core.Its working condition is complex,and its service life should be long.,which requires high reliability.PWR as well as newly developed different type of reactors have different control devices drive mechanism.This paper mainly do analysis and comparison about the working environment,mechanical transmission principle,structure, performance,service life and other aspects of PWR,HTR control devices drive mechanism.In addition,this paper is also based on the working principles of reactive control devices drive mechanism,also consider the trends of its design and test verification by the international countries,and discussed the method and feasibility of improving and perfecting the structure and function of drive mechanism.更多还原
