摘　　要：本研究以DOEL-2核电厂为研究对象,采用cosSyst程序对蒸汽发生器传热管破裂(SGTR)事故下的DOEL-2反应堆系统进行建模,将计算结果与电厂数据及RELAP5程序计算结果进行对比,评估cosSyst程序对SGTR事故预测的准确性。研究结果表明:cosSyst程序能够较好地模拟反应堆SGTR事故进程,且一回路系统及蒸汽发生器二次侧的主要热工水力参数与电厂数据吻合较好,表明cosSyst程序对SGTR瞬态事故具有良好的预测和分析能力。In this study,DOEL-2 nuclear power plant is used as the study object.The cosSyst code is used to model the DOEL-2 reactor system under the steam generator tube rupture(SGTR)accident.Comparing with the power plant data and RELAP5 simulation results,and evaluate the accuracy of the cosSyst code for SGTR accident prediction.The results show that the cosSyst code is capable to simulate the process of SGTR accident,and the major thermal hydraulic parameters of the primary system and the secondary side of the steam generator are fairly consistent with the power plant data.The cosSyst code is capable to predict and analyze SGTR transient accidents.
