Development of Multivolume Containment Model for MELCOR Code

MELCOR je termohidraulički program za analizu sigurnosti lakovodnih nuklearnih elektrana. U stanju je opisati cijelo postrojenje, sustav za proizvodnju pare i kontejnment u jednom modelu. Koristeći postojeći model kontejnmenta NE Krško za program GOTHIC, razvijen je odgovarajući model za program MELCOR. Opisan je način pripreme ulaznih podataka. Korištena je verzija programa MELCOR 1.8.5 preko SNAP sučelja.MELCOR is a integrated computer code that models the progression of severe accidents in light water reactor nuclear power plants. MELCOR can describe whole power plant and process in steam generator in one model. Using existing model of Krško nuclear power plant created in GOTHIC, MELCOR model is developed. Input data is described. Version 1.8.5 MELCOR is used through SNAP interface
