Atommash completed key stage in manufacture of bottom of nuclear reactor for Unit 3 of “Akkuyu NPP”

At procuring site, specialists with the help of oxygen-gas cutting performed cutting out of sector. For this, guides were installed inside blanks, along which gas-cutting machine moves along the length of blank. With the help of natural gas and oxygen, torch punches through 300 mm thick metal and performs clean cut. The plant's specialists have improved type of cutter nozzle, and now cutting is 4 times faster: two hours instead of eight.Then blank was sent to thermal furnace for annealing. In furnace, item was held for five hours at temperature of 620 Celsius degree. After inspection measures, blank will be sent to thermal and press section, where pipe will first be unbend, and then bottom of nuclear reactor will be stamped.

Atommash has assembled a semi-vessel of the new Reactor for the Tianwan NPS

The assembly of the semi-vessel elements of the Reactor was carried out on a vertical assembly test bench. Workers connected two shells of the nozzle area and a flange in a vertical position. Further, the 150-ton assembly was turned into a horizontal position using a rotator and the item was moved to the welding test bench. The upper semi-vessel is now ready for welding two circumferential welds. Atommash has extensive experience in cooperation with Chinese partners. In 2004, the enterprise supplied transport and process equipment for the first units of the Tianwan NPS.
