Abstract

Abstract

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.
