本文介绍了先进堆非能动余热排出系统专用程序MISAP2.0的理论模型及验证分析结果。结果表明:目前MISAP2.0程序已具备了基本的系统、设备模型,也能基本正确了计算典型物理过程,建议在MISAP2.0程序现有的基础上,增加一回路系统模块,并在应急给水箱模型和空气冷却器模型中增加蒸汽与过冷水接触的界面冷凝模型。经过进一步的试验评估验证后,该程序可以用于先进堆非能动余热排出系统原型和试验装置的设计和分析。
This paper introduces the theoretical model and verification analysis results of MISAP2.0, a program specific to advanced reactor passive residual heat removal system. The results show that: At present, MISAP2.0 program has been equipped with basic system and device model, and it can basically calculate the typical physical process. It is suggested to add the first-loop system module based on the existing MISAP2.0 program, In the tank model and the air cooler model, an interface condensation model that adds steam to supercooled water is added. After further test evaluation and verification, the program can be used for the design and analysis of prototype and test equipment of advanced passive stack exhaust system.
