The roof of the turbine building in Unit 1 of Akkuyu Nuclear Power Plant (NGS) has been completed. The entire installation process, which first began with the assembly of the beam on December 10, 2022, took three months.
The roof of the turbine building consists of nine expanded beams with a total weight of 1140 tons, including the roof decking. The beams, each weighing between 110 and 200 tons, were assembled at the construction site by connecting them in parallel on two sleds prepared for this process. The Liebherr 13000 heavy crawler crane was used during the assembly process.
The construction team installed several pieces of heavy and large turbine equipment, including the deaerator and feedwater storage tank, before installing the final beams of the structure. In the next step, the roof covering will be installed.
Sergey Butckikh, First Deputy General Manager of AKKUYU NÜKLEER A.Ş and Director of NGS Construction Works, said in his statement on the subject, “Assembling the roof beams of the turbine building is a complex and time-consuming process that requires careful preparation. Each beam is mounted with a precision of ten millimeters. Akkuyu construction and installation team successfully completed this task despite the tight schedule and harsh weather conditions. In the next stage of the construction of the turbine building, the assembly of the main components of the turbine generator will be carried out”.
Construction and installation work at the Akkuyu NPP site continues at all main and auxiliary facilities, including the four power units, coastal hydrotechnical structures, power distribution system, administrative buildings, training center and NPP physical protection facilities. All stages of construction at the Akkuyu NPP site are closely followed by independent inspection organizations and the Nuclear Regulatory Authority (NDK), the national regulatory agency.
