ACCIDENT LOCALIZATION SYSTEM RESPONSE IN THE CASE OF MAIN STEAM RELIEF VALVE OPENING
Résumé
Best-estimate methods have been employed for the analysis of the Accident Localization System (ALS) of the RBMK-1500 plant response in the case of main steam relief valve (MSRV) failure to re-close. An adequate modeling of complex multi-compartment and multi-suppression pool system of the Ignalina NPP ALS is
performed using C11AF version of the CONTAIN code (Murata, 1995). The mass and energy source functions used in this analysis were calculated using RELAP5/MOD3.2 (Fletcher et al., 1992).
The specific Ignalina NPP ALS design has two towers, and each of them houses by five condensation trays. A relevant issue is the functionality and importance of the condenser tray cooling system (CTCS). Several computations variants were carried out for the presented event: with a fully functioning CTCS and with failure of CTCS.
