摘　　要：基于经验证的单相和两相大空间自然对流管束传热模型,对RELAP5进行了改进,使得程序具备了模拟单相和两相大空间自然对流管束传热的能力。采用改进后的系统程序RELAP5和改进前的系统程序RELAP5对试验模拟体进行了对比计算,并采用试验数据对改进后的程序进行了验证,结果表明,改进后的系统程序计算结果与试验数据吻合较好。Based on the validated model of single phase and two phase free convection heat transfer from tube bundle, RELAP5 is improved with the ability to simulate the single phase and two phase free convection heat transfer for tube bundle. The test simulation result analyzed with the improved RELAP5 was compared with that from the original RELAP5. The comparison shows good agreements between the experiment data with the simulation result from improved RELAP5.
