摘要
棒电源系统是核电厂重要的系统之一,给控制棒驱动机构提供动力电源,通过提升、保持和插入控制棒棒束,控制反应堆堆芯的反应性,进而实现堆芯温度和核功率的控制。运行期间,不仅要保证提供的电源安全稳定,还有具备连续性。作者通过动、静态棒电源系统研究与分析,从原理保护、系统结构、运营维护、安全性能等方面进行对比,给漳州核电3、4号机组的优化改进提供了有效的判断依据。
The CRDM power supply system(RAM)is one of the important systems in nuclear power plants.It provides power to the control rod drive mechanism(CRDM).It controls the reactivity of the reactor core by lifting,maintaining and inserting the control rod bundle,thereby achieving the core temperature and nuclear power control.During operation,it is necessary not only to ensure the safety and stability of the power supply,but also to have continuity.Through the study and analysis of the dynamic and static CRDM power supply system,the author compares the principle protection,system structure,operation and maintenance,safety performance and other aspects,which provides an effective judgment basis for the optimization and improvement of Unit 3 and 4 of Guodian Zhangzhou Energy Co.,Ltd.
