en.Wedoany.com Reported - Four steam generators for Unit 4 of Turkey's Akkuyu Nuclear Power Plant (Akkuyu NPP) have arrived at the construction site. Manufactured by Atommash, a subsidiary of the mechanical engineering division of Russia's State Atomic Energy Corporation (Rosatom), the equipment was transported approximately 3,000 kilometers by sea. After unloading, the equipment was loaded onto self-propelled wheeled platforms and transferred to a temporary storage area.
The Akkuyu NPP will ultimately feature four Russian-designed VVER-1200 reactors. The first concrete was poured for Unit 1 in April 2018, Unit 2 in June 2020, Unit 3 in March 2021, and Unit 4 in July 2022. Rosatom is constructing these reactors under a "build-own-operate" model. Currently, work continues on all four units, as well as auxiliary facilities and a new town for the plant operator's staff. Unit 1 is scheduled to be commissioned later this year.
The mechanical engineering division of Rosatom has produced over 7,000 tons of equipment for the reactor halls of all four Akkuyu NPP units, including four VVER-1200 reactor pressure vessels and 16 steam generators. Sergei Butskikh, General Director of the project company Akkuyu Nukleer, stated that the steam generator is one of the key components of the reactor plant, and the delivery of the fourth set confirms the sustainable operation of the production and logistics chain. With the building structures ready, the site has received the necessary equipment for subsequent installation stages, enabling systematic construction and installation work for all nuclear power plant facilities.
Maxim Zhidkov, General Director of the Atommash plant, noted that since the plant began manufacturing equipment for the Akkuyu NPP, this process has been not only a mechanical operation but also a tangible contribution to improving the lives of millions of people. Modern nuclear power plants provide clean energy, create new job opportunities, drive scientific development and educational quality, and promote the application of nuclear technology in fields such as agriculture and medicine.
In early June, a 350-ton capacity overhead crane was installed in the turbine hall of Unit 3 at the Akkuyu NPP. The crane weighs a total of 385 tons, is 56.8 meters long, and has a lifting height of 43 meters. It is used for handling equipment and materials during the construction and operation of the unit, including turbine generator components, large pipeline assemblies, and more. The installation was carried out in three stages, using non-standard methods to complete full expanded assembly of the equipment on the ground, in order to shorten installation time and improve production safety. A similar technique was previously used for Unit 2, and the installation sequence was optimized based on feedback. One of the world's largest crawler cranes, the Liebherr LR 13000, was used on site to sequentially install the 320-ton crane bridge, the 68-ton main bogie, and the 10-ton auxiliary bogie, minimizing high-altitude connection operations and reducing labor intensity.
Experts from T2IC and TSM Enerji will subsequently install the load trolley, set up the control and safety systems, and complete static and dynamic tests. Oleg Didenko, Deputy Director of the Concealed Areas and Air Defense Department at TSM Enerji, stated that such technical solutions minimize connection operations at design positions, improving overall installation efficiency.
