MELCOR 2.2 Modelling for Fusion Reactor Analysis

During the 2018 EMUG meeting, there was a very interesting discussion about the physical models necessary to be implemented in MELCOR_2.2 for fusion reactor safety analyses and the current model already implemented in MELCOR fusion code. These are the information requested: o description of the phenomenon of interest; o safety relevance of the phenomenon for fusion reactor; o rank of importance ( 1: low; 2: medium; 3: High) ==> priority for code development; o if models to characterize the phenomenon have been already implemented in MELCOR fusion and the related version. The collected information is here summarized
