Abstract

The present invention relates to a nuclear reactor and a passive cooling system therefor. The nuclear reactor comprises at least one core (1) of nuclear fuel elements arranged immersed into a space filled with water and one or more circulation systems for circulation of cooling water from the core (1). Further, the nuclear reactor comprises means (22a, 22b) for utilizing the heat developed by the core (1), a volume (12, 21) filled with water, containing a high content of neutron poison, arranged separated but in direct hydraulic contact with the cooling water by means of at least one first density lock (14) arranged under the core (1) and an emergency circulation system. The invention is characterized in that the emergency circulation system comprises a space (11) arranged above the core (1) which is filled with pressurized steam and a plurality of openings (28) arranged above the core (1) for the passage of coolant to at least one channel (2b) arranged outside the space (11) for conducting the coolant to said means (22a, 22b) for utilizing the heat developed by the core. The passive cooling system is characterized in that it comprises a first tank (16) and a second tank (17) which are arranged in contact with each other for transferring liquid coolant from the first tank (16) to the second tank (17), the first tank (16) containing a quantity of coolant which is larger than the quantity of coolant in the tank (17) and a first circuit (16, 17, 18, 20, 34, 37, 38, 39, 41) for evaporating and condensing the coolant during normal operation and a second circuit (15, 16, 17, 19, 20, 34, 35, 36, 37) for evaporating and condensing the coolant during emergency cooling.
