| Abstract [eng] |
Many international programs and experiments were conducted to investigate the phenomenon of hydrogen generation during severe accidents such as QUENCH program QUENCH 20 test was conducted as the latest test to investigate the hydrogen production phenomenon, relocation of damaged fuel rods and boron carbide (B 4 C) reactions in BWR. This paper presents the LEI QUENCH tests modelling experience and based on gained experience development of numerical model for QUENCH 20 test using severe accident code RELAP/SCDAPSIM. Numerical analysis was provided using mod3.4 and mod3.6 code versions. The preliminary calculation results of the first attempt are presented for total hydrogen generation and cladding temperatures. The performed modelling using RELAP/SCDAPSIM code results demonstrated the advantages of mod 3.6 code version, comparing to the mod 3. 4 version. However, the modelling of a BWR control blades still remains challenging.. |
