大亚湾核电站全范围模拟机一回路热工水力学模型

Introduction to the RCS Thermal-hydraulic Model of the Full Scope Simulator of Daya Bay Nuclear Power Station

核电站模拟机的一回路热工水力学仿真模型需要同时满足精度和实时两个方面的较严格的要求,因而需要进行大量合理的简化。本文简要介绍大亚湾核电站全范围模拟机一回路热工水力学模型,着重介绍了其核心程序——DEFI的基本假设及计算方法。

Both the accuracy and real-time are quite strictly required for the RCS thermal-hydraulic model of the simulation of nuclear power station. So, alarge amount of reasonable simplifications should be carried on. This paper introduces the RCS thermal-hydraulic model of the full scope simulator of Daya Bay Nuclear Power Station, and emphasizes on the fundamental hypotheses and computation method of its kernal part——DEFI programe.
