en.Wedoany.com Reported - The Elektrostal Machine-Building Plant, a subsidiary of the Fuel Division of Rosatom, has completed the production of nuclear fuel required for the initial core loading of Unit 4 at the Kudankulam Nuclear Power Plant (KNPP). The product has been accepted by representatives of the customer, the Nuclear Power Corporation of India. The VVER-1000 reactor fuel assemblies were manufactured by TVEL JSC under contract, designed to supply fuel for the entire service life of Units 3 and 4 of the KNPP Phase 2. The initial fuel for Unit 3, manufactured by the Novosibirsk Chemical Concentrates Plant, was delivered to India in December 2025.

Since 2022, the two VVER-1000 units of KNPP Phase 1 have been using advanced TVS-2M nuclear fuel, which features a robust structure, a new generation of anti-fragment filters, and a higher uranium content. This has extended the continuous operating cycle of the units from 12 to 18 months, reducing the number of refueling outages and increasing power generation.

Located in the southern Indian state of Tamil Nadu, the Kudankulam Nuclear Power Plant is planned to house six VVER-1000 units with a total installed capacity of 6,000 MW. Units 1 and 2 of Phase 1 were commissioned in 2013 and 2017, respectively. Units 3 and 4 of Phase 2 are under construction, with progress exceeding 80%, while construction of Phase 3 units has surpassed 40%. Russia is responsible for fuel supply for Phases 2 and 3, with Phase 2 over 95% complete and Phase 3 approximately 40% complete. The Phase 2 units will be the first VVER-1000 nuclear power units to be simultaneously started on an 18-month fuel cycle.

The project is developed by the Nuclear Power Corporation of India, with Atomstroyexport JSC, a subsidiary of the Engineering Division of Rosatom, serving as the general designer and equipment supplier. A new fuel storage facility is designed to store fuel for four units, meeting the needs of Phases 2 and 3. Throughout the entire lifecycle of the nuclear power plant, Rosatom not only supplies nuclear fuel but also provides engineering services to improve unit operating efficiency.
