Example Embodiment

[0061] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0062] The nuclear power plant containment leakage rate detection method of the present invention comprises the following steps:

[0063] S1, the temperature probe collects in real time and transmits the temperature information in the containment to the data acquisition computer through the data acquisition device, the humidity probe collects in real time and transmits the humidity information in the containment to the data acquisition computer through the data acquisition device, and the pressure probe The pressure information and atmospheric pressure information in the containment vessel are collected and transmitted in real time to the data collection computer.

[0064] Once the data acquisition computer detects that...

Abstract

The invention relates to a leakage rate detection method and a system for a containment of a nuclear power station, which include that S1, through a data collection device, a data collection computer respectively receives temperature information in the containment collected and sent by a temperature probe in real time, humidity information in the containment collected and sent by a humidity probe in real time and pressure and atmosphere information in the containment collected and sent by a pressure probe in real time; and S2, a data processing computer receives all information collected by the data collection computer in the step S1, and calculates and outputs the leakage rate of the containment through a second display. A leakage rate detection system for the containment of the nuclear power station is further provided.

Description

technical field [0001] The invention relates to a detection method and system, more specifically, to a detection method and system for containment leakage rate of a nuclear power plant. Background technique [0002] Nuclear power plant containment leakage rate data acquisition and calculation technology belongs to the category of high-precision data acquisition. Nuclear power developed countries such as Europe and the United States are in a leading position in this technical field. Since the completion of Daya Bay and Qinshan nuclear power plants in China, this technology in my country is also in the process of continuous development. Among them, at present, there are three main branches of containment leakage rate measurement technology: the United States, France and Russia. Although the means of data collection and calculation models are different, the principle is the same, namely: according to the ideal gas state equation PV =nRT, to calculate the mass change rate of dry a...
