Thermal signal spectrum positioning system and positioning method for reactor loop system fault zone

Abstract

The invention discloses a thermal signal spectrum positioning system and a positioning method for a fault zone of a reactor loop system. The thermal signal spectrum positioning system for a fault zone of a reactor loop system includes a three-dimensional partitioned reactor cabin or a reactor building, and after the three-dimensional partitioning of the reactor cabin or the reactor building, For reactor compartments or reactor building blocks with multiple three-dimensional structures, set up one or more thermal imaging cameras around any one of the reactor compartments or reactor building blocks. The processing center is also connected to a thermal signal spectrum database and a system equipment location database; the thermal signal spectrum database is a thermal signal spectrum database formed by summarizing all reactor compartments or reactor building blocks at different angles and different operating states, and the system equipment location database It is a database that records equipment information and equipment location information in each reactor compartment or reactor building block.

Description

technical field [0001] The present invention relates to a pressurized water reactor nuclear power plant and a nuclear power plant, more specifically, to the monitoring and early warning of leakage or breach failures that may lead to a loss of water accident in the primary loop system of the reactor, and related components and subsystems, that is, the failure of the reactor loop system Disclosed are a positioning system and a positioning method for a thermal signal spectrum in a partition. Background technique [0002] In the pressurized water reactor nuclear power plant, the light water coolant in the primary circuit passes through the fuel assembly located in the pressure vessel, takes away heat, and transfers to the secondary circuit water in the steam generator to produce steam, and the steam passes through to drive the turbine generator generate electricity. [0003] In order to ensure the safety of the reactor, it is necessary to prevent loss of water accidents in the ...

AI Technical Summary

Problems solved by technology

[0004] At present, the pressure regulator water level monitoring, system temperature, and radioactive dose monitoring of the pressurized water reactor nuclear power plant and nuclear power plant for leakage or breach monitoring have the disadvantage that the detection time is slow and cannot be found in time

[0005] At present, the monitoring of the water level of the voltage stabilizer, the system temperature, and the radioactive dose have the disadvantage of not being able to accurately locate the location of the leakage or breach fault.

[0006] Through patent and literature search, in the relevant research reports at home and abroad, there is no thermal signal monitoring of the reactor compartment or reactor building area, and there is no report on the use of thermal signal monitoring to judge the leakage or breach of the reactor coolant system
