Rosatom's TVEL Fuel Company initiated nuclear fuel supply for Kudankulam NPP’s units 3 and 4. Utilizing advanced TVS-2M fuel, the VVER-1000 reactors in Tamil Nadu extend fuel cycles to 18 months, improving efficiency. Units 1 and 2, commissioned in 2013 and 2017, already benefit from these upgrades. Construction of additional units continues.
