A Usina Nuclear de Kudankulam (ou KKNPP) é a maior usina nuclear da Índia, situada em Kudankulam, no distrito de Tirunelveli, no estado de Tamil Nadu, no sul da Índia.

Two reactors (KKNPP-1 and 2) have been operating since 2013 and 2016, respectively, while two more (KKNPP-3 and 4) are currently under construction following the groundbreaking ceremony held in February 2016.

KKNPP-3 e 4 são reatores de água pressurizada de design russo (modelo VVER-1000/V-412). Esses reatores são projetos repetidos do KKNPP-1 e 2, com melhorias adicionais baseadas no comissionamento e no feedback da experiência operacional.

For the construction of these two units, Dextra supplied 350,000 Bartec couplers to connect rebars in the reactor building, auxiliary building, and spent fuel storage structures.

Bartec is a trusted splicing system, well-known for its high performance in tension, compression, and fatigue. It is widely used in the construction of buildings, bridges, metro systems, nuclear reactors, and more.

Unit 3 is scheduled for completion in March 2023, with Unit 4 following in the subsequent year.

Upon completion, these two reactors will add 2,000 MW of electricity to the existing units, bringing the total site capacity to 4,000 MW.
