Das Kernkraftwerk Kudankulam (oder KKNPP) ist das größte Kernkraftwerk Indiens und liegt in Kudankulam im Distrikt Tirunelveli im südindischen Bundesstaat Tamil Nadu.

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 und 4 sind Druckwasserreaktoren russischer Bauart (Modell WWER-1000/V-412). Bei diesen Reaktoren handelt es sich um Wiederholungskonstruktionen von KKNPP-1 und 2, mit weiteren Verbesserungen, die auf der Inbetriebnahme und Rückmeldungen aus Betriebserfahrungen basieren.

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.
