The invention discloses a containment vessel thermotechnical hydraulic comprehensive test device, which comprises a containment vessel simulation body, a gas supply system, a passive heat conduction system and a data system. The gas supply system is provided with a plurality of discharge ports, and the discharge ports are respectively arranged at different positions in the containment vessel simulation body and are used for releasing gas with different parameters to simulate gas release in the containment under different accident conditions; the data system comprises a plurality of data acquisition units and a data receiving unit, and the data acquisition units are distributed at different positions in the containment simulation body and used for acquiring thermal mechanical parameters atdifferent positions in the containment simulation body; the data receiving unit is electrically connected with the data acquisition units and is used for receiving the thermal mechanical parameters transmitted by the data acquisition units. According to the device disclosed in the invention, simulation test research on complex thermal-hydraulic phenomena such as thermal stratification, multi-gas components and distribution in the containment vessel and coupling behaviors of the containment vessel and a safety system can be realized.

Description

technical field [0001] The invention belongs to the field of nuclear technology, and in particular relates to a thermal-hydraulic comprehensive test device for containment. Background technique [0002] At present, a large number of passive safety systems are used in the third-generation nuclear power technology in the world to deal with working conditions such as power outage accidents or active safety system failures. However, the start-up and operation of passive systems are very complicated, and their start-up and operation processes are unpredictable and Sure. [0003] As a typical type of nuclear power system in a pressurized water reactor nuclear power plant, its containment vessel often has a large size and volume. Under this scale, the thermal parameters such as temperature, pressure, and composition in the containment vessel must have uneven distribution. problems, and these thermal parameters have a very large impact on the operation of passive systems. [0004]...
