Pressure containment separation system of nuclear power plant

摘要

The pressure containment system of nuclear power plants is in the field of ensuring that nuclear power plants can operate safely in various modes, including emergency reactors, and aims to control the air flow in the containment of nuclear power plants. The containment containment system as an containment compartment of a nuclear power plant includes a containment separation device installed at the bottom that divides the compartment and located in an annular gap between the compartment and the compartment to block the compartment air from each other and include at least one gate. It is possible to connect containment buildings with pressure drops. The system is further characterized by an air supply connected to each gate of the gravity separator and an annular manifold connected thereto. At the same time, each of the valves of the device for separating the containment is manufactured in the form of an inflatable slide which isolates the air environment of the containment with the air filled and connects the air environment of the containment with the retracted state. In emergency mode, the air supply to the expandable gate stops and drops, opening the annular gap completely to provide convection throughout the convection space. The system of separating containment buildings can be applied to containment buildings of all types of nuclear power plants.
