核电厂辐射监测系统方案优化研究

Research on Optimization Scheme of Radiation Monitoring System for Nuclear Power Plant

核辐射数据是核电厂中独有的监测数据。现役核电厂中,辐射监测系统主要包括计算机系统和就地辐射监测仪。辐射监测系统在电厂中虽然属于非安全级系统,但是核电厂的辐射监测数据对于核电厂运行状态评价是至关重要的。通过分析福清1、2号机组厂房辐射监测系统(KRT)和AP1000堆型辐射监测计算机系统(RMS)的系统网络架构、系统通信方式和就地辐射监测仪的技术缺陷。借鉴核电仪控或其他相关行业的技术发展方向和工程经验从改进系统网络架构、改良系统通信方式和使用先进探测技术等方面,提出核电厂辐射监测系统的优化解决方案。

The monitoring of radiation data is a system that unique to nuclear power plant.As for the nuclear plant in service,the radiation monitoring system is formed by local radiation monitors and integrated computer system.Although the safety classification of radiation monitoring system is NC,the radiation monitoring data of nuclear power plant is very crucial to evaluate the running state.By analyzing the system network architecture,system communication mode and local radiation monitor technical shortcomings of FuQing1&2units Plant Radiation Monitoring System(KRT)and AP1000model radiation monitoring computer system(RMS).According to the technological development and experience of nuclear I&C and other related industries,put optimization scheme for nuclear power radiation monitoring system.
