核电站KIT系统改造中的反应堆热功率监视功能开发

Development of Reactor Thermal Power Surveillance Functions of KIT System Transformation in Nuclear Power Plant

该文主要涉及大亚湾核电站KIT系统升级改造中与反应堆热功率监视功能开发相关的内容。热功率监视模块接收来自反应堆一回路的温度、压力、流量等信号，计算反应堆的实时热功率和滑动平均热功率，对热功率进行实时显示并设置报警功能。该文从改造背景、功能需求、计算原理、功能应用等方面对热功率监视模块的设计开发进行了描述。

The article mainly deals with the function development related to reactor thermal power surveillance in the KIT sys- tem upgrading transformation in Daya Bay Nuclear Power Plant. The thermal power surveillance module receives the signals of tem- perature, pressure, flow rate, etc. from the primary loop of reactor, calculates the real time thermal power and the moving average val- ues of thermal power, real-timely displays the thermal power and sets up the alarm function. The paper systematically describes the design and the development of the thermal power surveillance module from the aspects of the innovation background, the functional requirements, the calculation principle, and the function application, and so forth.
