The Volgodonsk branch of JSC "AEM-technology" "Atommash" (part of the Rosatom machine-building division) has begun the final stage of manufacturing the reactor for the Akkuyu nuclear power plant in Turkey. Currently, a trial assembly of the reactor vessel with internals and the lid is underway.
"The trial assembly of the "nuclear matryoshka" allows engineers to ensure that all components and elements of the reactor are positioned accurately to within one thousandth of a millimeter. This work confirms the reactor's readiness to operate for at least 60 years and simplifies its installation at the NPP construction site. A successful trial assembly serves as a global quality marker.
An internals shaft weighing 73 tons is installed inside the reactor vessel. The installation of the baffle (38 tons), the block of protective tubes (68 tons) and the reactor lid (90 tons) is carried out sequentially. During assembly, fastening keys will also be installed to secure the centering device for the lid.
The reactor is a vertical cylindrical vessel with an elliptical bottom, inside which the core and internals are located. From above, it is hermetically sealed with a lid, on which control and protection mechanisms are installed, as well as nozzles for вывод cables of in-reactor monitoring sensors. The first power unit of the Akkuyu NPP is scheduled to be commissioned in 2026.
