en.Wedoany.com Reported - Mashinostroitelny Zavod (MSZ) in Elektrostal, Russia, part of Rosatom's fuel company TVEL, has completed the production of the first fuel batch for Unit 4 of the Kudankulam Nuclear Power Plant in Tamil Nadu, India. TVEL is contracted to supply fuel for the entire service life of Units 3 and 4 at Kudankulam. Previously, the first fuel batch for Unit 3 was manufactured by Rosatom's Novosibirsk Chemical Concentrates Plant (NZKhK) and delivered to India in December 2025.

The Kudankulam Nuclear Power Plant will comprise six units equipped with VVER-1000 reactors. The project originated from an intergovernmental agreement between India and Russia signed in 1988. Units 1 and 2 (Phase I) are already in operation, while Units 3 to 6 (Phases II and III) are under construction. The plant owner and operator is Nuclear Power Corporation of India Limited (NPCIL), the general contractor is JSC ASE (Rosatom's engineering division), the chief designer is Atomenergoproject, and the equipment designer is OKB Gidropress.

Since 2022, the Kudankulam NPP has been using improved TVS-2M fuel. This fuel, characterized by its robust design, new anti-debris filters, and higher uranium content, ensures more reliable and cost-effective operation of the power units. The introduction of this fuel has also extended the operating cycle from 12 to 18 months.
