不同破口面积下蒸汽发生器传热管破裂事故试验研究

Test Investigation on Steam Generator Tube Rupture of Different Break Sizes

在高压综合实验装置(HPITF)上实验研究了1根和3根蒸汽发生器传热管双端破裂事故。测定了事故期间的热工水力参数,对两种工况的实验结果进行了分析比较。采用RELAP5/MOD2程序对单根传热管双端破裂事故工况进行了计算,并将计算数据与实验结果进行了比较,以验证该程序对蒸汽发生器传热管破裂(SGTR)事故的分析能力。

Test investigation on SGTR of the single tube break and three-tube break were carried out on High pressure integral test facilities( HPITF). The thermal-hydraulic behaviors during SGTR were measured, and the experiment results from two cases were analyzed and compared. Post-test analyses for a single tube double-ended break accident were performed with RELAP5/MOD2 program, and the data of calculation were compared with the experiment results to verify the analytic capability of RELAP5/MOD2 program for SGTR accident.
