System for passive aftercooling of vessel nuclear reactor includes contour of natural circulation of heat carrier, intermediate heat exchanger of aftercooling with two-phase thermo-siphons, intermediate two-phase circuit of aftercooling connected to outboard heat exchanger-condenser heat transfer surface of which is arranged as vertical pipe bunch placed in outboard area between outer and inner boards of the vessel, and system for supply of compressed air to outboard area to lower part of inter-pipe space of outboard heat exchanger-condenser. For possibility of bringing into action at emergency situation without energy sources and crew operation system of compressed air supply additionally has balloon with stock of compressed air and shutoff valve with electromagnetic drive with possibility of its passive opening at de-energization. |
