Remote analysis and management platform for eddy current data of steam generator tubes in nuclear power station

Abstract

The invention discloses a remote analysis and management platform for eddy current data of steam generator tubes in a nuclear power station, which comprises a data acquisition computer, a data acquisition server, a data analysis and management computer and a data analysis and management server, wherein the data acquisition computer and the data acquisition server are arranged on the site of the nuclear power station and are used for acquiring and storing eddy current testing data of the steam generator tubes; the data analysis and management computer and the data analysis and management server are arranged in a laboratory or a control room; the data analysis and management server and the data acquisition server communicate by adopting a file transfer protocol to realize remote transmission, analysis, management, sharing, secrecy and decryption of the data; and the data of the two servers are synchronously updated. The technological difficulties of remote real-time data transmission, data management, instant communication, information sharing and data secrecy and decryption in traditional senses are eliminated, and a more advanced nondestructive testing data analysis working mode is supplied, so that personnel and equipment are utilized to the maximum degree, and a primitive platform is provided for scientific researches in future, such as historical data base establishment, simulation experiments, computational simulation and the like.

Description

technical field [0001] The invention relates to a remote analysis and management platform for eddy current data of a steam generator heat transfer tube of a nuclear power plant. Background technique [0002] In addition to ensuring the normal and safe operation of the units, nuclear power plants also face periodic safety review PSR (HAD103-11) and deferred operation review (the design life of in-service nuclear power plants is mostly 30-40 years). In the review work, the review of safety elements of nuclear power plants is an extremely important review content. [0003] The safe operation of nuclear power plants is protected by three barriers: the first barrier - fuel pellets and cladding, the second barrier - a strong pressure vessel and a closed primary circuit system, and the third barrier - containment. For a typical three-circuit nuclear power unit, the sum of the heat transfer tube area of ​​an evaporator is about 6000 square meters, so the total area of ​​the heat tr...

AI Technical Summary

Problems solved by technology

At present, the traditional mode of data analysis and data management in domestic nuclear power plants is adopted, that is, an internal temporary local area network is built as a platform for data collection, data analysis, and data management. This local area network platform model makes related workstations, servers, and switches all The temporary construction at the data collection site exposed many shortcomings, such as: 1. The stability and service life of the supporting equipment cannot be guaranteed after long-distance transportation. Before each on-site project starts, it is time-consuming and labor-intensive to build the platform; 2. Personnel And equipment redundancy, cannot be used optimally, and the economy is not high

In future multi-site services, if this model continues to be adopted, a large number of workstations, servers, debugging personnel, data analysis and management engineers, etc. will be required on site, and the cost of equipment and personnel will be too high; 3. It is not conducive to scientific research and international exchanges
