摘要

非能动余热排出系统是球床模块式高温气冷堆(HTR-PM)的重要安全系统。由于非能动余热排出系统与堆芯主回路之间通过辐射换热耦合在一起,为了分析事故工况下非能动余热排出系统的运行特性,提出了用区域重叠分解方法实现非能动余热排出系统与主回路系统的耦合计算。基于此方法开发了耦合计算分析工具TINTE-RHRS,建立了多回路系统模型。应用TINTE-RHRS程序模拟了失冷不失压事故下HTR-PM余热排出系统的热工水力特性,计算结果验证了堆芯主回路与余热排出系统耦合计算的必要性,分析了事故工况下投入运行列数和环境温度等对系统运行特性的影响。

Abstract

The passive residual heat removal system (RHRS) is an important safety system for the HTR-PM reactor. Due to the thermo-dynamic coupling between the reactor core and the passive RHRS, an overlapping domain decomposition coupling method is employed for the analysis of the operating characteristics of the passive RHRS of the HTR-PM. The software TINTE-RHRS is developed based on this methodology and is used for the coupling calculation, and an integration solution can be obtained for both the primary system and the passive RHRS. The system models are also presented in this paper. The thermal-hydraulic characteristics of the passive RHRS in the pressurized loss of a forced cooling (PLOFC) accident are simulated using the TINTE-RHRS code. The importance of the coupling calculation between the primary system and the passive RHRS is shown; and the effects of the number of operating systems and the air temperature on the operating performance for the passive RHRS are also addressed.
