Method for ensuring hydrogen explosion safety at nuclear power plants

The invention relates to emergency protection of nuclear power plants, particularly to technologies for mitigation of consequences or fire prevention and prevention of explosive gas accumulation, which ensure hydrogen explosion safety in premises of the containment dome (hereinafter - CNT) at nuclear power plants (hereinafter - NPP) with water-cooled power reactor (hereinafter - VVER). Moreover, the offered invention can be used at other facilities having the risk of development of potentially hazardous emergency processes, related to the emission of a large amount of light combustible gas andits localization in closed premises of a facility. The technical result attained by the declared invention consists in the reduction of the risk of gas medium inflammation in premises of NPP CNT, aswell as in the provision of self-damping of weak burning waves, reduction of their intensity in case of gas medium inflammation in premises of NPP CNT and in reduction of dynamic loads on walls of premises of NPP CNT.
