Further Investigation of Core Degradation Using Quench Test Facility Results

Authors: Antoaneta Stefanova, Rositsa Gencheva, Pavlin Groudev


This paper presents an application of the ASTEC V2r3p3 computer code for simulation of QUENCH-12 experiment. The test has been performed to investigate the behavior of VVER type of fuel assemblies during severe accident conditions. In the performed analyses it has been assessed the mass of generated hydrogen during the experiment flooding of overheated core. The comparison of ASTECv2r3p3 calculated results with measured test data shows good agreement.
