摘要
某研究性反应堆是以中国原子能科学研究院101研究堆为原型设计的重水反应堆,其堆外核测量系统是反应堆仪表控制系统的重要组成部分,该系统可实时监测反应堆堆芯外中子注量率并向功率调节系统、保护系统等提供必要的反应性信号。本文针对MHWRR运行特性和方式,阐述该反应堆堆外核测量系统的改造设计,详细介绍其系统组成与功能、系统设计、可靠性要求和设备改造及布置等内容。
A research reactor is a heavy reactor designed on the base of China’s 101 reactor,its ex-core nuclear measurement system is an important part of reactor instrument control system,the system can real-time monitor outside of reactor core neutron fluence rate and provide reactive signal to the power control system,protection system.According to the operation characteristics and mode of MHWRR,this paper describes the reformation design of ex-core nuclear measurement system of the reactor,and introduces system composition and function,system design,reliability requirement and equipment modification and arrangement in detail.
