非能动余热排出系统模化及验证分析

摘要

Mature scaling theory is the foundation of experimental veriifcation of reactor safety system. Taking the passive residual heat removal system from a foreign power plant as an example, this paper determines modeling proportional system of the passive residual heat removal system under the circuit energized accident condition by modeling analysis. It carries out the numerical calculation of engineering prototypes and modeling system by RELAP5/MOD3.2 software. The numerical results validate the accuracy of modeling analysis of the passive residual heat removal system.%模化理论是核反应堆安全系统试验验证的基础。文中以国外某核电厂的非能动余热排出系统为对象，通过模化分析确定一回路失电事故工况下非能动余热排出系统的模化比例系统；采用RELAP5/MOD3.2软件对工程原型和模化系统进行了数值计算，数值结果验证了非能动余热排出系统模化分析的正确性。
