The Kudankulam Nuclear Power Plant, located in the Tirunelveli district of Tamil Nadu, is India's highest-capacity nuclear power station and a landmark of international technical cooperation with Russia. Developed under a 1988 intergovernmental agreement, the plant utilizes advanced VVER-1000 pressurized water reactors. It serves as a critical pillar for South India's energy grid, providing reliable base-load power to support the region's rapid industrialization and urbanization. Kudankulam is the first nuclear facility in the country to implement state-of-the-art passive safety systems, ensuring cooling stability even in the event of a total power loss. Its coastal location on the Arabian Sea provides access to seawater for cooling and has simplified the logistics of transporting heavy reactor components by sea. With ongoing expansion aimed at reaching a total of six units, Kudankulam is set to become one of the largest nuclear power complexes in the world, playing a decisive role in India's strategy to increase its share of clean, carbon-free energy.
