Abstract

The invention discloses a test device for a containment heat passive export system. The test device for a containment heat passive export system includes: a containment simulator; a compressed air supply system and a helium supply system that are connected to the containment simulator; a steam supply system, which is in connection with the containment simulator; a heat exchange tube test piece, which is disposed in the containment simulator; a forced circulation loop, which is connected to the heat exchange tube test piece to form dynamic heat export circulation; a natural circulation loop, which is connected to the heat exchange tube test piece to form passive heat export circulation, with the forced circulation loop and the natural circulation loop working selectively; and a data acquisition system, which is used for collecting parameters inside the containment simulator. The test device for the containment heat passive export system provided by the invention can simulate the accident environment of the containment heat passive export system so as to facilitate the study on the performance of the containment heat passive export system.

Description

technical field [0001] The invention belongs to the technical field of nuclear energy safety, and in particular relates to a test device for a containment heat passive derivation system. Background technique [0002] The containment is the last safety barrier for nuclear power plants to prevent the release of radioactive fission products. The design of the current third-generation nuclear power plants includes a containment passive cooling system. Once an accident triggers its action, the water storage tank in the system can be To maintain passive operation, the waste heat of the core is effectively removed by spraying and cooling the surface of the steel containment vessel, so as to ensure the safety of the containment vessel structure, and the operator does not need to intervene within 72 hours. However, the results of the Fukushima nuclear accident in Japan showed that in the extreme case of double damage from the earthquake and tsunami, the off-site power supply could no...
