In particular, the approach to the consideration of beyond design accidents, among which the severe ones, should be especially coherent and complete. The beyond design accidents considered should be clearly identified and the method by which they are prevented and/or mitigated should be explained for example it should be clarified if the defence from possible events caused by a molten core outside the vessel is based on the containment of the molten core within the vessel itself (flooding of the cavity and cooling of the vessel from outside) or on the refrigeration of the molten core on the floor of the containment. The experimental and theoretical basis of the demonstration of the adequacy of the solutions chosen should be clearly identified.
