Title
(EN) SYSTEM FOR SEPARATION OF PRESSURE VOLUME OF CONTAINMENT OF NUCLEAR POWER PLANT
(RU) Система разделения гермообъёма контайнмента атомной электростанции
Abstract
(EN)
FIELD: nuclear equipment. SUBSTANCE: invention relates to safe operation of nuclear power plants (NPP) in various modes, including emergency ones, and is aimed at control of air flows in NPP containment. System of separation of the pressure volume of the contaminant of the nuclear power plant into isolated rooms contains a device for separation of the pressure volume, which is located in the annular gap between the flooring separating the rooms and the wall of the containment. System also includes an air supply device and an annular header connected to it, connected to inflatable gates, which are made with possibility of isolation of air masses of the containment rooms in the air-filled condition and connection of air masses of the containment rooms in the lowered state. EFFECT: increased safety of NPP operation both in normal and emergency mode due to provision of connection of aerial mediums of NPP containment facilities in wide section and along entire perimeter of containment at accident in containment. 12 cl, 5 dwg

Изобретение относится к области обеспечения безопасной эксплуатации атомных электростанций (АЭС) в различных режимах, включая аварийные, и направлено на обеспечение контроля воздушных потоков в контайнменте АЭС. Система разделения гермообъема контайнмента атомной электростанции на изолированные помещения, содержит устройство разделения гермообъема, расположенное в кольцевом зазоре между перекрытием, разделяющим помещения, и стенкой контайнмента. Система также содержит устройство подачи воздуха и соединенный с ним кольцевой коллектор, соединенный с надувными шиберами, выполненными с возможностью изоляции воздушных сред помещений контайнмента в наполненном воздухом состоянии и соединения воздушных сред помещений контайнмента в спущенном состоянии. Технический результат – повышение безопасности эксплуатации АЭС как в нормальном, так и в аварийном режиме за счет обеспечения соединения воздушных сред помещений контайнмента АЭС в широком сечении и по всему периметру контайнмента при аварии в контайнменте. 11 з.п. ф-лы, 5 ил.
