ROSATOM machine-building division Atomenergomash’s Volgodonsk Branch of JSC AEM-technology has started a new project manufacturing Passive Core Flooding System Tanks for the Akkuyu NPP Unit 1 in Turkey.Atommash will manufacture the Passive Core Flooding System Tanks for Units 1 and 3 of the Akkuyu NPP under construction. Each Passive Core Flooding System Tanks consists of three shells and two bottoms. The shells are manufactured of 60 mm thick stainless steel sheet. Twenty-four shells are used for the set of Passive Core Flooding System Tanks.Some of the blanks were already subjected to the incoming inspection, the bottoms and shells are being machined. On turning-boring machines, edges are cut for circumferential welds, on horizontal boring machining centers work is carried out with holes and nozzles. Preparation for penetrant test is performed. The assembly of sleeves was started on the bottoms of the tanks.215.jpgPassive Core Flooding System Tank belongs to the second stage of passive NPP safety systems. The system includes 8 hydraulic tanks with a volume of 120 cubic meters. During operation at the plant, an aqueous solution of boric acid is stored in tanks, heated to a temperature of about 60 degrees. When the pressure in the primary circuit drops below a certain level, the liquid is automatically supplied to the reactor and the core is cooled.The Akkuyu NPP project in Turkey includes four power units with Russian VVER reactors of the generation III+ with increased safety and improved technical and economic characteristics. The Rosatom engineering division carries out the design and construction of the facility. The electric capacity of each NPP unit will be 1200 MW.For reference:JSC Atomenergomash is a supplier of equipment for the reactor plant and the turbine hall for all four units of the plant. The Akkuyu NPP is the world's first nuclear power plant project implemented according to the BOO (“build-own-operate”) model.
