摘要
堆芯中子通量测量系统是压水堆核电站核测系统的主要组成部分,用于测量反应堆堆芯中子注量率水平,从而提供反应堆的功率分布情况,同时校准堆外核仪表系统和LOCA监侧系统。因此堆芯中子通量测量系统是核电厂重要仪表系统,它的运行可靠性直接影响核电厂的安全稳定运行。本文沿着中国大陆核电的建设历程讲述国内压水堆核电机组堆芯中子通量测量系统的发展情况,并以此为基础对其未来的发展趋势做出初步预测,可为核电厂堆芯中子通量测量系统变更改造、创新设计提供重要参考。
The core neutron flux measurement system is the main component of the nuclear measurement system in PWR nuclear power plant.It is used to measure the neutron flux level of the reactor core,thereby providing the power distribution of the reactor and calibrating nuclear ex-core power range channel and the margin to LOCA computer.Therefore,the core neutron flux measurement system is an important instrument system for nuclear power plants,and its operational reliability directly affects the safe and stable operation of nuclear power plants.This article follows the construction of nuclear power plants in China's Mainland to describe the development of the core neutron flux measurement system of the domestic PWR nuclear power unit,and to make a preliminary prediction about its development trend in the future,which providing an important reference for the modification,renovation,innovative design of core neutron flux measurement system.
