A nuclear power plant eau system automatic reading system and reading method

Abstract

The invention discloses an automatic reading system for a nuclear power plant EAU system, which comprises a channel extension module and a data collection component. The channel extension module is connected with an EAU manual reading box and is provided with a plurality of types of data collection channels, the data collection component comprises a plurality of types of data collection modules, and each data collection module is connected with the corresponding data collection channel; the data collection module is used for collecting EAU data in the EAU manual reading box through the data collection channels. According to the automatic reading system and a reading method for the nuclear power plant EAU system, the time consumption in manual reading can be reduced, the labor can be saved,the personal safety and the accuracy of data recording can be ensured.

Description

Technical field [0001] The invention relates to the field of nuclear power, in particular to an automatic reading system and a reading method of the EAU system of a nuclear power plant. Background technique [0002] The nuclear power plant’s reactor building instrument system (ie EAU) is used to detect the containment deformation during the containment construction and the in-service CTT test (ie the containment test). It must also be carried out regularly during the life of the containment structure. Test reading. Currently, the measurement and reading method of EAU meters in nuclear power plants is manual measurement and reading. Commonly used instruments are FLUKE-51 and GK-403. The measurement and reading method is single-channel measurement and reading. After the measurement and reading of one channel is completed, use the turntable to switch the channel to perform the next channel measurement and reading. The readings of the plumb line system are distributed in multiple ...

AI Technical Summary

Problems solved by technology

[0004] 1. Long test and reading time: it takes about 1 hour to manually test and read a set of data

During the containment pressure test, the deformation of the reactor building changes with time, and the manual measurement and reading takes a long time, which leads to the asynchronous readings of different instruments in the same set of data, which introduces errors to the data analysis and calculation results

[0005] 2. Multiple people are required to work together: At present, manual reading requires at least two groups of 6 people to work at the same time to complete

[0006] 3. Data records are chaotic or even wrong: during the containment suppression test, the number of CTT personnel on duty is not enough to conduct the measurement and reading, and the manual measurement and reading is carried out by the on-site contractor. Due to factors such as uneven personnel quality, short time window and personal recording habits, etc., There are problems with chaotic or even wrong data records, which brings troubles to data analysis and even requires re-reading

[0007] 4. The data needs to be input into the computer for analysis and calculation: the manual measurement data is a handwritten form, which takes a lot of time to input into the computer, and there is a possibility of input errors

[0008] 5. The on-site environment is harsh: during the commissioning period, the plant environment is harsh, and the measurement and reading work is often carried out at night. On-site flaw detection is often carried out in the plant and passages where the instrument is located, and there are industrial risks and risks of false exposure
