Severe Accident Progression Analysis Induced by Station Blackout for CANDU Station

With an integral system analysis code, the analysis model for CANDU station was built, which contains the primary heat transfer system, calandria system, end shield system and the secondary side of steam generators. The station blackout accident was selected to make further thermal-hydraulic analysis. The comparison of the results with ISAAC2.0 code was performed, and it shows that timing of the major events is fairly close.
