钠冷快堆堆外核测量系统设计

核测量系统是核电厂仪控系统信息功能中最重要的测量系统之一,核测量系统从反应堆完全停堆到150％额定功率的范围内,对反应堆的换料、启动、功率运行、停堆等各种状态下的反应堆核功率、周期等参数进行监测,并向保护系统、控制室系统等提供相关参数,用于控制显示或保护.快堆的核测量系统与压水堆有较多不同,本文从快堆的特殊核物理现象,...

Design of Nuclear Measurement System for Fast Reactor

Nuclear measurement system is one of the most important measurement systems in the information function of Instrument and Control system of nuclear power plant.The nuclear measurement system monitors the nuclear power,power period and other parameters of the reactor under various states,such as refueling,start-up,power operation and shutdown,from the complete shutdown to 150%power.The system provides relevant parameters for control system or protection system.There are many differences between the nuclear measurement system of fast reactor and PWR.In this paper,the design of nuclear measurement system of fast reactor is compared and analyzed from the special physical characteristics of fast reactor,detector layout,detection channel setting,detector selection,range coverage design and other aspects.Combined with real project design,this paper introduces the structure of nuclear measurement system,detector selection and technical characteristics of data processing.
