HYDROGEN AND OXYGEN CONCENTRATION CONTROL SYSTEM IN GASEOUS MEDIA Russian patent published in 2023 - IPC G01N27/417 

FIELD: nuclear power plants.

SUBSTANCE: measurement equipment used to measure the concentration of hydrogen and oxygen in the atmosphere of the containment of a water-cooled power reactor (WCPR), as well as in gaseous media of various types of nuclear power plants. The gas analyzer 1 includes an input hydrogen sensor 3 installed in the channel 2, an input catalytically active element 4, an output hydrogen sensor 5, an oxygen sensor 6 and an output catalytically active element 6. Each of the sensors 3, 5, 6 of hydrogen and oxygen is equipped with a device 10, 13 for climatic and/or electrical effect. The registration and control means includes a block 9 of converter modules and a computing device 21 connected to it. The unit 9 of converter modules includes software-controlled modules 16 of amplifier-converters, each of which is connected by its outputs by electrical lines 15, 18 to the corresponding sensor 3, 5, 6 and to the computing device 21, and software-controlled diagnostic modules 12, 17, each of which is connected by its outputs by electrical communication lines 11, 14 with the corresponding device 10, 13 of climatic and/or electrical influence and with a computing device 21.

EFFECT: increasing the reliability and accuracy of measuring the concentration of hydrogen and/or oxygen in gaseous media.
