Title
(EN) CONTAINMENT BUILDING SEPARATION SYSTEM AT A NUCLEAR POWER PLANT
(FR) SYSTEME DE SEPARATION DE BATIMENT DE CONFINEMENT DANS UNE CENTRALE NUCLEAIRE
Abstract
(EN)
A system for dividing a pressurized volume of a containment building of a nuclear power plant relates to the field of providing for safe operation of a nuclear power plant in various regimes, including emergency regimes, and is directed towards allowing monitoring of air flows in a containment building of a nuclear power plant. A system for dividing a pressurized volume of a containment building of a nuclear power plant into isolated rooms comprises a device for dividing the pressurized volume, which device is arranged in an annular gap between a floor dividing the rooms and a wall of the containment building, an air supply device and an annular collector which is connected to the latter and is connected to inflatable shutters which are capable, in a state filled with air, of isolating air environments of rooms of the containment building and, in a deflated state, of connecting air environments of rooms of the containment building. In an emergency regime, an air supply to the inflatable shutters is stopped, the latter are lowered, completely opening the annular gap and allowing convection throughout the volume of the containment building. The system for dividing a pressurized volume can be used in containment buildings of nuclear power plants of any type.
