FIELD: construction.
SUBSTANCE: invention relates to construction equipment, namely to protective reinforced-concrete enclosures of nuclear power plants. Protective reinforced-concrete enclosure of nuclear power plant includes reinforcement frame consisting of interconnected transverse and longitudinal working reinforcement rods installed inside concrete block, which external side is directed towards impact action, and back side is internal border of NPP premises. Inside the concrete block, between the longitudinal reinforcement rods and the back side of the protective reinforced concrete enclosure, a steel expanded metal sheet is installed, in which diamond-shaped cells are made formed by bearing inclined ribs, ends of which are fixed on end supports of protective reinforced concrete enclosure by means of a welded joint.
EFFECT: technical result of proposed invention consists in improvement of safety of nuclear power plants, simplification of design of protective reinforced concrete enclosure of nuclear power plants, reduction of physical volumes and time of NPP construction.
