摘　　要：200 MW低温核供热堆的余热排出系统由3个耦合的自然循环回路组成。本文对该系统的热工水力特性进行了理论分析。在一维质量、动量和能量守恒方程的基础上建立了非能动余热排出系统的数学模型,并编制程序对模型进行了数值求解,模拟了非能动余热排出系统的瞬态特性。经验证,该系统的排热能力满足设计要求。The residual heat removal system of 200 MW Heating Reactor is constituted by 3 coupled natural circulations. The thermal-hydraulic analysis numeric model of the passive residual heat removal equation, momentum equation and energy equation. model and simulate the heat removal process of the the system meet the design requirements. of the system has been performed in this paper, and the system has been constructed based on 1-demansion mass The program in this paper has been used to compute the system. The results show that the heat transfer ability of
