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.
