The passive protection system of a nuclear reactor contains a protective shell in which the reactor vessel with thin-walled metal blocks filled with ceramic refractory material and fixed on the inner surface of its lower part is installed. The outer surface of the lower part of the reactor vessel is placed in a sealed chamber, which is connected by steam and condensate piping in its upper and lower parts with a condenser outside the containment located above the sealed chamber. At the same time, capillary-porous material filled with two-phase coolant is applied on the outer surface of the lower part of the reactor vessel and on the inner surface of the containment chamber.
