摘要: 广东岭澳核电二期工程控制棒控制系统和控制棒棒位监测系统(以下简称棒控棒位系统)采用基于法国AREVA的安全级仪控平台TXS技术和数字化技术,以及冗余设计技术手段,实现了反应堆温度和功率的集中控制。采用大功率晶体管实现了对控制棒的"一带一"控制;采用分组编码探测器对控制棒在堆芯中的位置进行监测。本文对其设计要求和设计特点进行了介绍,并将设计结果与岭澳核电一期和秦山二期棒控棒位系统的设计结果进行了比较。结果表明,岭澳二期的棒控棒位系统能为运行人员和维护人员提供丰富的信息,方便了系统的运行和维护,提高了系统的可靠性。Abstract: The TXS,digital and redundant techniques are applied in the rod control and position indication system（RGL） to perform the control of power and temperature in the reactor integrally in Ling’ao Phase II project.The high power transistors are used to implement the control of the coils one by one in the control rod drive mechanism（CRDM）.The grouped position detectors are used to monitor the position of the control rod in the reactor core.This paper introduces the requirements and traits of system design of RGL system in Ling’ao phase II.Comparing with the system design of Ling’ao phase I and Qingshan phase II,RGL system in Ling’ao phase II is more convenient for the information exchange,operation and maintenance,and is with high reliability.
