Abstract

The invention relates to a nuclear reactor containment cooling simulation system and method based on external spraying. The system comprises containment, experiment gas nozzle, a raw water high-level water tank, a variable-frequency spraying water pump, a spraying nozzle and a liquid storage tank, wherein the raw water high-level water tank, the variable-frequency spraying water pump, the spraying nozzle and the liquid storage tank are sequentially connected, the spraying nozzle is located right above the containment, and the experiment gas nozzle is located in the containment; a data collecting device and a mass spectrometer are arranged outside the containment, an inlet flowmeter, an inlet thermocouple, an inlet pressure sensor and an experiment gate valve are sequentially serially connected between the variable-frequency spraying water pump and the spraying nozzle; an outlet thermocouple and an outlet flowmeter are sequentially serially connected between the spraying nozzle and the liquid storage tank. Water is injected through the opening and closing of a water injection gate valve and the experiment gate valve, the spraying nozzle sprays water, and the features and rules of the internal thermal-hydraulic phenomena of the containment after the outside of the containment is sprayed according to obtained data. The nuclear reactor containment cooling simulation system is reasonable in design and widely applicable and provides technical and data support for the engineering construction and design transformation of advanced nuclear reactors of China.

Description

technical field [0001] The invention relates to a technology in the nuclear industry field, in particular to a nuclear reactor containment cooling simulation system and method based on external spraying. Background technique [0002] Nuclear energy is an alternative energy that can be developed on a large scale under the current technical level, and plays an important role in my country's energy structure. However, due to the potential radiation safety risks of nuclear power plants, safety issues are the key issues that must be resolved in the large-scale development of nuclear power. [0003] According to the current situation of nuclear power development and relevant policy requirements, new requirements are put forward for the design and safety analysis of PWR nuclear power plants. The containment is the last barrier containing radioactive substances in the defense-in-depth system of a nuclear power plant. Under the accident conditions of a nuclear power plant, whether t...
