Since the hydrogen combustion behavior in a multi-compartment vessel was a key issue to the containment vessel integrity during a severe accident, NUPEC developed an analytical hydrogen combustion model and incorporated in to MELCOR, which could evaluate mechanistically the hydrogen combustion behavior to track the flame front propagation in a multi-compartment vessel. The new model was validated under the homogeneously pre-mixed gas conditions using the results of the GRS/Battelle multi-compartment hydrogen combustion test. Following to the above work, using the tests results, simulating transient severe accident conditions from NUPEC large-scale combustion test facility, scenario oriented test analyses were carried out to validate the new model extensively. It was clarified that the MELCOR code replaced with the new combustion model could analyze sufficiently the combustion behavior at low flame velocity as well as the deflagration behavior at high flame velocity in a multi-compartment vessel.
