NUCLEAR ENERGY PROCESS SYSTEM AND METHOD FOR ITS OPERATION Russian patent published in 2023 - IPC G21D7/00 

FIELD: nuclear power.

SUBSTANCE: system contains a recuperative heat exchanger 3, coupled with a high-temperature electrolyser 2 on the one side, and with a pipeline for steam from a nuclear power plant 1 and pipelines for hydrogen and oxygen with a cooler 8 on the other side, drying units 9 on pipelines for hydrogen and oxygen, a water separator 10 on a pipeline for hydrogen downstream of the cooler 8 and process electrolysers 14 connected to the electrical connection line 12. Moreover, the process electrolyser 14a is connected to the pipeline for hydrogen through the purification unit 13, and the high-temperature electrolyser 2 and the process electrolysers 14 operate at basic duty, and the low-temperature electrolyser 4 operates at maximum duty when the consumer load demand fails, and at the minimum duty during the maximum load demand by consumers. The exhaust steam after the NPP turbine is fed to the high-temperature electrolyser 2 through the recuperative heat exchanger 3, where it is heated to the operating temperature of the high-temperature electrolyser 2 by the heat of hydrogen and oxygen leaving the high-temperature electrolyser 2.

EFFECT: increasing the reliability and efficiency of the nuclear energy process system.
