Reactor loop system fault section heat signal spectrum positioning system and method

Abstract

The present invention discloses a reactor loop system fault section heat signal spectrum positioning system and method. The system provided by the invention comprises a pile cabin or a reactor building configured to perform a three-dimensional section, and a plurality of three-dimensional structure pile cabins or reactor building section blocks are provided after the three-dimensional section of the pile cabin or the reactor building is performed; one or more than one thermal imagers are arranged at the periphery of any one pile cabin or any one reactor building section block, and the thermal imager is connected with a data calculation and analysis processing center which is connected with a heat signal spectrum database and a system device location database; the heat signal spectrum database is formed according to the collection of all the pile cabins or the reactor building section blocks with different angles and different running states, and the system device location database is configured to record device information and device location information in each pile cabin or each reactor building section 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
