Abstract
The invention provides a nuclear power plant containment shell pressure test strength monitoring system which includes data acquisition modules and a data reading and processing module. The data acquisition modules are distributed in different parts of a containment shell and used for acquiring parameter signals of different parts of the containment shell, wherein the parameter signals include deformation parameters, stress parameters, temperature parameters and settlement parameters. The data reading and processing module is connected with the data acquisition modules, and is used for reading and receiving the parameter signals from the data acquisition modules, eliminating unreasonable parameter signals, and performing calculation according to the reasonable parameter signals to get containment shell strength analysis data. The invention further provides a nuclear power plant containment shell pressure test strength monitoring method implemented using the nuclear power plant containment shell pressure test strength monitoring system. According to the technical scheme, through optimization of the data reading and analytical processing method of the existing nuclear power plant containment shell pressure test strength monitoring system, the problem that there is a need to read data manually and the data reliability is poor in the prior art is solved.
Description
technical field [0001] The invention relates to the field of containment strength analysis, in particular to a nuclear power plant containment pressure test strength monitoring system and monitoring method. Background technique [0002] The containment vessel is the enclosure structure of the nuclear reactor. It is the third safety barrier after the nuclear fuel cladding and the primary circuit pressure vessel, and it is also the last safety barrier. Its function is to limit and eliminate the fission products in the accident when the primary circuit pipeline ruptures and causes a loss of water accident, so as to ensure the safety of nuclear power workers and the public. In addition, the containment can also prevent internal facilities from being impacted by the outside world, and has a major security mission. In order to evaluate the working performance of the containment in the crash state, in accordance with the requirements of RCC-G- and other relevant codes and regulati...
