The Energomashspetsstal plant (EMSS) is producing a large-sized shell of the reactor vessel core for Unit 3 of the Akkuyu Turkish nuclear power plant (NPP). An ingot weighing 415 tons, intended for the manufacture of this shell, was cast in the electric arc furnace shop of PJSC "EMSS" on March 2, 2021.
Currently, the ingot has been delivered to an automated forging complex for forging. It is planned to complete the manufacture of the shell of the reactor vessel in the third quarter of 2021. The net weight of the product after the end of the machining process will be 119.55 tons, diameter - 4.6 meters, height - 5.3 meters.
The contract for the manufacture of blanks for the reactor vessel of power unit No. 3 of the Akkuyu NPP was signed by EMSS PJSC in 2020. According to the signed contract, EMSS will manufacture and supply to the customer 10 items of the VVER-1200 reactor pressure vessel, including a large-size shell. To date, 9 out of 10 KR parts are ready and shipped to the customer. Now the production of PJSC "EMSS" is the last, the largest blank - the shell of the core of the VVER-1200 reactor pressure vessel.
In addition to the reactor vessel for power unit No. 3 of the Akkuyu NPP, EMSS produces blanks for the steam generator, collector, bottom, main circulation pump, main circulation pipeline and pressure compensator.
NPP "Akkuyu" after completion of construction will become the first nuclear power plant in Turkey. The project includes four power units with VVER-1200 generation 3+ reactors of Russian design. Commissioning of the nuclear power plant is scheduled for 2023, by the centenary of the founding of the Republic of Turkey.
