Abstract
(EN)
The invention is related to safety systems for nuclear power plants (NPP) which can be used in various operational modes, including emergency mode, and is aimed at controlling air flows inside NPP containment buildings.NPP containment building separation system dividing the NPP containment building into isolated rooms. It includes the containment building separation shutters located in the circular gap which divides the containment building rooms and the containment building walls; an air supply unit connected to a manifold ring which, in turn, is connected to the air-inflated shutters designed to ensure insulation of the airspace inside the containment building rooms when inflated and at connecting the airspace when deflated. In emergency mode the air supply to the air-inflated shutters is terminated, the shutters get deflated and fully open the circular gap which ensures convection process throughout the whole area of containment building.A containment building separation system can be used for any type of NPP containments.

Un système de division du volume étanche de confinement d’une centrale nucléaire fait partie du domaine d’exploitation sécurisée de centrales nucléaires dans différents modes, y compris dans des modes d’urgence, et vise à assurer un contrôle sur les flux d’air dans un confinement de centrale nucléaire. Le système de division du volume étanche de confinement d’une centrale nucléaire en locaux isolés comprend un dispositif de division de volume étanche disposé dans un intervalle circulaire entre le plancher séparant les locaux et un mur de confinement, un dispositif d’amenée d’air et, relié à celui-ci, un collecteur annulaire connecté à des dispositifs à volets gonflables réalisés de manière à pouvoir isoler les milieux aériens des locaux de confinement à l’état gonflé d’air et connecter les es milieux aériens des locaux de confinement à l’état dégonflé. En mode d’urgence, l’injection d’air dans les dispositifs à volets gonflables est coupée, lesdits volets sont abaissés de manière à découvrir complètement l’intervalle circulaire pour assurer la convection dans tout le volume du confinement. Le système de division du volume étanche de confinement peut s’utiliser dans les centrales nucléaires de tous types.
