摘要： 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.

摘要： Primary circuit auxiliary systems. The invention provides integrity and normal operation of the T-unit, including cases when the unit operates under abnormal conditions. The flow mixing T-unit of reactor volume control system which includes a T-piece connected with two ends to the bypass line carrying the coolant of one temperature, and with the additional opening to the makeup system pipeline carrying the coolant of a different temperature under emergency and an insert which separates the coolant flows of different temperature, the insert is installed upstream the coolant flow in the bypass so that its outer part is located upstream the coolant inlet into the T-unit, and its inner part is cantilevered inside the T-unit and forms a tube with openings in the area of the T-piece. The T-unit is provided with an adapter mounted at its outlet and forming, together with the insert, a coaxial channel for coolant flow.

摘要： Emergency Core Cooling System under loss-of-coolant accidents, including a sump protection device (SPD) in the emergency cooling system of a VVER, and the filter module and filter element of the sump protection device, which is to protect sumps from accumulation of debris in case of a loss-of-coolant accident.
Disclosed is a VVER emergency cooling system sump protection device, comprising a system of filters installed at the intake opening of the upper part of the sump located in the reactor containment bottom and connected to the intake of emergency cooling system pipeline. It consists of header-connected filter modules preventing debris from entering the intake of emergency cooling system pipelines; each filter module has slotted grates on sides and on top, and filter elements arranged inside are designed as laterally slotted filtration pipes and perforated distribution tubes (inside the pipes) the inner cavities of which are connected to headers.

摘要： The group of inventions refers to heat exchange machinery. The device includes a tank with an outlet fitting and a steam source, a deaerator column with a cover and water inlet and vapor blowdown fittings located on the same, containing lower and upper deaeration sections. Each section includes pressure and distribution trays forming a jet chamber in the space between them, and random element packing. Deaeration sections are separated by a hydraulic seal formed by the edge of the upper section pressure tray and the projection connected to the deaerator column cover. The water inlet and vapor blowdown fittings are located inside the hydraulic seal projection with openings in it. The lower edges of the openings are located higher than the upper edge of the hydraulic seal by a value exceeding the sum of overflow height of the coolant over the edge and hydraulic resistance of the hydraulic seal channel. The total cross section of the openings is determined by equality of steam pressure in the blowdown fitting and in the space inside the hydraulic seal projection. This increases the operation reliability.
