Russian nuclear giant ROSATOM announced that the dome of the internal containment was installed in the design position inAkkuyu NPP Unit 1, and thus the sealing loop was completed. The IC dome has a spherical shape and consists of 16 mounting sections weighing 215 tons. The structure of the dome also includes the metal structure of the platforms for servicing the sprinkler system weighing 46 tons. Especially for lifting the dome to a height of +61.700, a traverse weighing 75 tons was developed and manufactured. The total weight of the structure lifted by the Liebherr LR 13000 crane was 340 tons. The enlarged assembly of the dome was performed at the Akkuyu NPP site and took 3.5 months.After concreting the dome part of the IC, the final stage of construction and installation works of the outer containment will begin.Construction and installation works at the Akkuyu NPP site are ongoing at all sections of the main and auxiliary facilities construction: four power units, on-shore hydraulic engineering structures, power distribution systems, administrative buildings, training center, physical protection facilities of the future NPP. All construction stages at the Akkuyu NPP site are thoroughly monitored by independent inspection organizations and the Nuclear Regulatory Authority of Turkey, the national regulatory authority.Akkuyu NPP is the first nuclear power plant being built in the Republic of Turkey. The Akkuyu NPP project includes four power units equipped with Generation 3+ VVER reactors of Russian design. The capacity of each NPP power unit will be 1200 MW. Currently, the project is entirely financed by the Russian side. Akkuyu NPP is the first project in the global nuclear industry being implemented according to the Build-Own-Operate model.
