Abstract

The invention relates to a containment vessel shielding cooling system for an ocean nuclear power platform, and the system comprises a cooling box body which is used for being arranged on a containment vessel body; a water ballast space which is communicated with an external cold source; the water ballast tank is communicated with the cooling box body, the liquid level in the water ballast tank is higher than that in the cooling box body, and the water ballast tank is used for supplementing cooling water into the cooling box body. Passive water injection and sufficient cooling water supply are realized in the containment vessel body by utilizing the pressure difference generated by gravity, and the cooling water in the cooling box body absorbs waste heat of a reactor core to form steam to be discharged from the pressure relief exhaust part in cooperation with the use of the cooling box body and the pressure relief exhaust part, so that long-term waste heat discharge is realized, in addition, the containment shielding cooling system can still conduct out waste heat after accidents such as coolant pipeline crevasse and main steam pipeline crevasse occur, and the containment body is prevented from losing efficacy due to overpressure.

Description

Technical field[0001]The present application relates to the field of maritime nuclear power safety facilities, and in particular, there is a safety shell shielding cooling system for marine nuclear power platforms.Background technique[0002]At present, the ocean nuclear power platform is a new energy carrier with nuclear reactor, which is of great significance for the development of deep sea resources; because the deep-sea nuclear power platform is far from the mainland and is bad, it is difficult to conduct effective emergency support, It is necessary to utilize the sufficient cooling water in the deep sea, bringing out the core, cooling the safety shell to ensure the effectiveness of the safety shell.[0003]In some related technologies, commercial nuclear power plants and marine nuclear power devices, generally set non-movable heat-export systems, derived pile of heat, cooling water of the cooling heat exchanger, is generally limited water source, ie fixed volume of water tank, etc....
