Embodiment Construction

[0040] The following describes the present invention in detail, and the features and advantages of the present invention will become more clear and definite along with these descriptions.

[0041] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0042] In the present invention, the containment vessel refers to the nuclear reactor containment vessel, which is the outermost building of the pressurized water reactor, and refers to the outer shell building that contains most of the systems and equipment of the nuclear steam supply system, and is used to accommodate the reactor pressure vessel and some safety vessels. The system (including the main syst...

Abstract

The invention provides a passive containment cooling system provided with heat pipe liquid guide devices. The system comprises an inner containment, an outer containment, a cooling device arranged at the top of the outer containment, the heat pipe liquid guide devices arranged on the inner containment as well as a guiding device which is arranged between the inner containment and the outer containment and used for guiding air circulation; a cooling agent is sprayed on the inner containment from the top, and a liquid film is formed. By means of the heat pipe liquid guide devices, on one hand, breakage of the liquid film can be inhibited, the heat exchange efficiency between the liquid film and air is improved, and heat on the surface of the inner containment is discharged out of the inner containment; on the other hand, heat on containment surface which is not covered with the liquid film can be guided into heat exchange space between the inner containment and the outer containment and finally discharged out of the outer containment. The passive containment cooling system provided with the heat pipe liquid guide devices has the characteristics of high-efficiency heat exchange, safety, reliability, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor safety, in particular to a passive containment cooling system with a heat pipe liquid guiding device. Background technique [0002] The containment is the last safety barrier to prevent the leakage of radioactive materials in the event of an accident in a nuclear power plant. The large-scale advanced pressurized water reactor currently being developed in my country adopts a technology similar to AP1000. AP1000 is the third-generation nuclear power system developed by Westinghouse Corporation of the United States. It adopts a passive containment cooling system. The cooling system adopts a double-layer containment structure, the outer layer is a concrete shell, the inner layer is a steel containment The total internal volume of the containment vessel is only a few thousand cubic meters. In the case of an accident, once the high-temperature and high-pressure medium is released in the reacto...
