Installation of the first turbine hall overhead crane the at AKKUYU NPP unit 1 has started

December 13, 2022, Büyükeceli, Mersin province, Turkey. – Installation of a hoisting overhead crane in Unit 1 turbine hall has commenced at the Akkuyu NPP construction site. This is the first of three overhead cranes to be installed in the turbine hall.

An overhead electric double-girder crane with a lifting capacity of 350 tons is the first in order of installation, and the largest of them. The crane will be used for lifting and handling operations in the turbine hall during the construction and installation and as well as the NPP operational stage.

The crane service life will be at least 70 years. It has three hoisting devices: main hoist, auxiliary hoist and electric hoist with lifting capacity of 350, 40 and 6.3 tons respectively. The length of the crane is 56.8 meters; its height is 5.8 meters and the lifting height is 43 meters. The total weight of the crane is 385 tons.

Currently, work on the installation of attached mechanical and electrical equipment is underway in the turbine hall of Akkuyu NPP Unit 1. Then, in accordance with the factory documentation, a step by step connection of related equipment will be done. Experts will need at least 37 days to perform subsequent work, including the commissioning and handover of the crane into operation. 

"We have installed the first and main of the three overhead cranes in the turbine compartment. Once the installation is complete, all the cranes will be used to install equipment and move heavy loads in the turbine hall. During power unit operation, the cranes are needed to organize maintenance and repair of the main and auxiliary equipment of the turbine building. The service life of each crane is designed for the whole operation life of the power unit; this means that the highest degree of reliability is provided in design and manufacturing," First Deputy Chief Executive Officer – Director of NPP under Construction Sergei Butckikh noted.

Construction and installation works at the Akkuyu NPP site are ongoing at all areas of the main and auxiliary facilities construction: four power units, on-shore hydraulic engineering structures, power distribution systems, administrative buildings, training center, NPP physical protection facilities. All construction stages are thoroughly monitored by independent inspection organizations and the Nuclear Regulatory Authority of Turkey (NDK).

For reference: 

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.

According to terms and conditions of the Inter-Governmental Agreement between the Russian Federation and the Republic of Turkey, the NPP's first power unit is supposed to be commissioned within 7 years after obtaining all construction authorizations and licenses. Given that the construction license for Unit 1 was obtained in 2018, the deadline is 2025. At the same time, the project stakeholders are making their best efforts to complete the construction of Unit 1 and ensure its readiness for commissioning test in 2023, a jubilee year for the Republic of Turkey.
