Reactor Pressure Vessel Installed in Kudankulam
New Delhi: The reactor pressure vessel for Unit 5 has been installed at the construction site of the Kudankulam Nuclear Power Plant. The installation took place on Monday, June 15.
According to a statement by the Embassy of the Russian Federation, on June 15, at the construction site of the Kudankulam Nuclear Power Plant in India, the reactor pressure vessel for Unit 5 was installed in its design position, with the participation of the Engineering Division of the Rosatom State Corporation, the project’s general designer and contractor.
The operation was carried out using the Open Top method, in which heavy equipment is lifted into the reactor building by a high-capacity crane before the dome is erected. This method has already been successfully implemented by the Rusdia-India team during the construction of the 2nd phase of the Kudankulam NPP.
The reactor vessel was manufactured at the Atommash plant of Rosatom’s Machine-Building Division in Volgodonsk, Rostov Region. The total weight of the reactor vessel delivered to the Kudankulam NPP in 2025 is about 300 tonnes.
Following the installation of the reactor vessel, work will begin on the assembly of the main reactor plant equipment, including steam generators, main circulation pumps, main coolant pipeline modules, the pressurizer, and emergency core cooling system tanks.
“The key to the success of the Kudankulam NPP project is the long-standing and fruitful cooperation between Russia and India. Indian specialists are currently constructing four power units based on the Russian design, while two other units have been generating electricity for more than ten years. All of this reflects strong teamwork aimed at strengthening the partnership between our two countries,” emphasized Mikhail Novikov, Director for Projects in India at JSC Atomstroyexport.
