Melcor code application to hydrogen issue for Czech NPPs

Popis výsledku v původním jazyce

For the purposes of hydrogen risk evaluation during severe accident conditions and mitigation system design, a methodology was developed in the NRI, based on the MELCOR simulations, analyzing conditions for flame acceleration (FA) and deflagration to detonation transition (DDT) using criteria described in the OECD state-of-art report. The computation of FA criterion and DDT one was linked to the MELCOR 1.8.5 and 1.8.6 detailed input models of VVER-440/213 and VVER 1000 plant containments. The methodology itself consists of several steps starting with whole plant simulation of selected severe accident scenarios where mass and energy sources for a consequent containment simulation are generated. This simulation of containment response is provided with adetailed model of the containment including calculation of both criteria ? and ?. Checking of both criteria is provided continuously, usually assuming no random ignition to identify phases in the severe accident course with serious hydrog
