| 摘 要： | 针对AP1000非能动余热排出系统(PRHRS)的具体结构，采用FORTRAN程序设计语言自主开发了瞬态分析程序RETAC-PRHRS(REactorTransientAnalysisCode-PassiveResidualHeatRemovalSystem)。利用编制的程序对PRHRS误开启事故进行分析，得到了堆芯归一化热功率、流量、最小偏离核态沸腾比(MDNBR)、系统压力、PRHRS流量等主要系统参数的响应特性。分析结果表明，在PRHRS误开启事故发生时，主要系统参数未超出规定限值，不会触发反应堆停堆。并将计算结果与热工水力分析软件，包括西屋公司开发的LOFTRAN及GSE公司开发的Topmeret/THEATRe的计算结果进行对比。对比趋势符合良好，从而证明了AP1000PRHRS建模的合理性。

| Abstract: | A transient analysis program RETAC-PRHRS(REactor Transient Analysis Code-Passive Residual Heat Removal System) for PRHRS in AP1000 was developed using FORTRAN language.The inadvertent operation accident of the PRHRS was analyzed and transient characteristics of some main system parameters were obtained,including normalized thermal power,normalized flow rate and MDNBR in the core,system pressure,flow rate in the PRHRS.The results show that the main system parameters do not exceed specified limits and will no... |
