The first concrete was poured into the foundation slab of the reactor building at the Kudankulam Nuclear Power Plant (NPP) Unit six, which is supported by Russia. The first two NPP power units have shown that they can operate at nominal power levels for an extended period. According to Russian nuclear power company Rosatom, which is building the NPP, the second-stage power units are being built, with work on Unit three underway to prepare for the installation of the reactor pressure vessel. The first concrete was laid at power unit No five in June of this year, and the first concreting at power unit No six began on December 20. The third stage of the Kudankulam NPP, which corresponds to the main construction period, will provide additional power capacity to ensure the industrial and commercial development of businesses in Tamil Nadu and India as a whole. Additionally, it will promote greater confidence in friendly countries' prospects to expand peaceful nuclear cooperation by utilising the most advanced projects of high-capacity nuclear power units of Russian design, according to Andrey Lebedev, ASE JSC. The equipment required for the installation at Kudankulam's Units 5 and 6 is currently being delivered, and the construction process is underway. The Kudankulam Nuclear Power Plant or Kudankulam NPP or KKNPP is India's largest nuclear power plant, located in Kudankulam in the Tirunelveli district of Tamil Nadu. Following the signing of the General Framework Agreement (GFA) on April 10, 2014, for the construction of Units three, four, negotiations with the Indian party for the construction of Kudankulam NPP Units five, six began, with the result that an agreement was reached that these Units would be built following the same design as Units 3, 4. The Credit Protocol to the Intergovernmental Agreement of December 5, 2008, as well as the GFA for KudankulamNPP Units 5, 6 were signed on June 1, 2017.
