Title:
COMBUSTIBLE GAS CONTROL METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/057927
Kind Code:
A1
Abstract:
A combustible gas control system, comprising a plurality of safety-level passive hydrogen recombiners provided in designated positions within a containment, each hydrogen recombiner being used to automatically start and continuously eliminate hydrogen by means of a hydrogen-oxygen recombination reaction when the hydrogen concentration within the containment exceeds a preset start threshold in design expansion conditions and severe accident conditions without significant damage being caused to a reactor core, and to automatically stop hydrogen elimination until the hydrogen concentration within the containment is lower than a preset stop threshold. In design expansion conditions and severe accident conditions of nuclear power plants without significant damage being caused to a reactor core, combustible gas may be completely passively reduced, avoiding combustible gas explosion, and further improving the safety of nuclear power plants.
