The Volgodonsk branch of JSC AEM-technology Atommash has started installing internals into the first Steam Generator Vessel for AKKUYU NPP that is being constructed in Turkey.
A steam generator is a heat exchanger that is a part of the reactor plant and belongs to the items of the first-class safety.
During the process of installation, professionals install finished heat-exchange tubes of different configuration into the Vessel. Then the coils ends are expanded in turns and welded to two headers of the steam generator. The total number of the components to be installed is 11,000.
The works are performed at the clean assembly site, where two vessels can be placed simultaneously.
The next production stage is welding small bottoms. The equipment will be subjected to hydraulic test and a whole range of different inspections including an eddy-current test of heat-exchange tubes.
At present, there are three more steam generator vessels for AKKUYU NPP at different stages of manufacture at Atommash.
