Abstract

The invention relates to a containment test system and method. The containment test system comprises at least two groups of gas supply units; at least two groups of adjusting units, wherein the air inlets of the adjusting units are communicated through a communicating pipeline; a first isolating valve is arranged on the communicating pipeline; the at least two pressurizing ports are communicated with the containment; wherein one adjusting unit corresponds to one air supply unit and one pressurizing port, the air inlet of each adjusting unit is communicated with the air outlet of the corresponding air supply unit, and the air outlet of each adjusting unit is communicated with the corresponding pressurizing port. On one hand, the gas supply section of the pressurizing opening can be increased, the pressurizing time of the containment is shortened, and therefore the containment testing efficiency is improved; and on the other hand, the plurality of sub-pressurizing systems can be mutually switched and can be mutually standby, so that the influence on the containment test caused by the damage of a single pressurizing system is avoided.

Description

technical field [0001] The present application relates to the technical field of nuclear power plant containment, in particular to a containment test system and method. Background technique [0002] The containment vessel is the nuclear reactor containment vessel, which is the outermost building of the pressurized water reactor. It refers to the outer shell building that contains most of the systems and equipment of the nuclear steam supply system. Complete isolation, expect to achieve the function of a safety protection barrier. [0003] A containment test is required every 10 years to verify the tightness and structural strength of the containment. During the test, it is necessary to fill the containment with compressed air that meets the requirements to simulate the working conditions required for the containment test. However, the charging efficiency of conventional containment testing systems is low. SUMMARY OF THE INVENTION [0004] Based on this, it is necessary ...
