Analyses are presented οη hypothetical accidents in NET/ITER involving: -air ingress in the graphite-coated plasma chamber through a breach in the vacuum vessel (LOVA); -loss-of-coolant inside the vacuum vessel with water ingress in the plasma chamber (inside LOCA); -loss-of-coolant outside the vacuum vessel (outside LOCA); -loss-of-power with the worst case conditions of absence of any cooling by natural convection (total LOCA) , and with natural convection flow (total LOFA). Ιn this paper the modeling of these accidents and important results are shown
