The installation of the outer protection shell of the reactor building of the 1st power unit of the Akkuyu Nuclear Power Plant (NPP), built by the Russian State Nuclear Energy Corporation Rosatom, has been completed.
According to the statement made by Rosatom, another important stage has been completed in the Akkuyu NPP, which was built in Gülnar district of Mersin.
The process of concreting the dome of the outer protection shell of the reactor building belonging to the 1st power unit of the power plant has been completed.
Two tower cranes, six concrete distribution booms and 34 concrete mixer trucks were used in the concreting process.
The concreting process, which was done in four separate stages, took 104 days. A total of 3,511 cubic meters of high-strength concrete mixture was placed in this part of the outer protection shell.
Akkuyu Nükleer AŞ General Manager Sergei Butckikh, whose views were included in the statement, stated that the external protection shell is one of the main security systems of the power unit and said, “The solid reinforced concrete structure will reliably protect the reactor unit from external influences. Completing the concreting process of the external protection shell is another important part of NPP safety.” “It will allow us to start the installation of the passive heat removal system, which is the element of he said.
The outer protection shell of the reactor building is made of reinforced concrete and is designed to withstand the harshest conditions, such as earthquakes up to magnitude 9 on the MSK-64 scale and hurricanes up to 60 m/s.
