Method for Ensuring Hydrogen Explosion Safety at Nuclear Power Plant

摘要

Hydrogen explosion safety in premises of the containment dome (CNT) at nuclear power plants (NPP) with water-cooled power reactor (VVER). The method for ensuring hydrogen explosion safety at nuclear power plants comprises ventilation of premises of the nuclear reactor premises and hydrogen recombination in premises of the nuclear reactor premises by its catalytic oxidation. In accordance with the declared solution, a reflector is placed on the way of potentially emergency propagation of a pressure hydrogen-containing steam-gas jet, apertures are made in the walls between premises of the nuclear reactor containment dome with a size equal to minimum 35% of the surface area of the said walls, while excess heat is withdrawn in areas of potential localization of hydrogen-containing steam-gas mixture burning sources.
