These provisions align with India's Make-in-India initiative, aiming to develop domestic nuclear manufacturing capabilities and reduce dependency on imported components.
The scope of cooperation also extends to non-power applications of nuclear technology, representing broader utilization of atomic energy beyond electricity generation. This includes potential applications in medical diagnostics, industrial processes, and agricultural productivity, demonstrating the comprehensive nature of the partnership.
Fuel Cycle and Technical Support
A central element of the strengthened partnership involves expanding cooperation in the complete fuel cycle for nuclear power generation. Russia, through its specialized fuel company TVEL, already supplies India with advanced nuclear fuel designs, including the TVC-2M fuel type. This fuel enables the Kudankulam reactors to operate on an 18-month fuel cycle instead of the traditional 12-month cycle, significantly improving the economic efficiency and operational performance of the power units.
Maintaining reliable fuel supply and advanced technical support represents a critical component of sustained nuclear power plant operation. The agreement ensures continuity of fuel deliveries and technical expertise necessary to optimize the performance and safety standards of existing and future reactors.
Second Site Development and Future Expansion
The joint statement references ongoing discussions regarding a potential second site in India for nuclear power plant development featuring Russian reactor technology. Indian authorities have undertaken formal procedures for site allotment in accordance with agreements previously signed between the two nations. The identification and preparation of a second site represents a significant expansion of the bilateral nuclear cooperation framework, potentially doubling or substantially increasing India's capacity to deploy Russian-designed nuclear reactors.
Technical specifications for new nuclear power plants utilizing VVER-1200 reactor units are currently being proposed by the Russian side, signaling concrete advancement in planning for future phases of bilateral cooperation.
Emerging Technologies and Small Modular Reactors
Beyond large-capacity conventional reactors, the cooperation framework increasingly incorporates emerging nuclear technologies. Russia's Rosatom State Corporation has been actively promoting small modular reactors (SMRs) as a complementary technology for India's nuclear energy expansion. SMRs possess approximately one-third the generating capacity of traditional nuclear power reactors while maintaining the ability to produce substantial quantities of low-carbon electricity.
India has demonstrated interest in deploying SMRs for targeted applications, including energy supply to data centers and remote regions with limited grid infrastructure. Indian public sector undertakings, including Rail Vikas Nigam Ltd under the Ministry of Railways, are currently in discussion with Rosatom regarding potential deployment of SMRs to meet energy requirements for ongoing rail projects, including the Rishikesh-Karnaprayag railway line.
Russia uniquely possesses expertise in floating nuclear power plant technology, an innovative field where no other nation has demonstrated comparable capabilities. This technology presents potential opportunities for India to explore novel approaches to nuclear energy deployment in geographic areas where traditional land-based facilities may present logistical challenges.
India's Broader Nuclear Energy Objectives
India's commitment to expanding nuclear energy capacity reflects both environmental and economic imperatives. Currently, India operates 24 nuclear reactors with a combined capacity of 7,943 MWe. An additional six reactors totaling 4,768 MWe are under construction, while approximately ten units representing roughly 7 gigawatts of capacity remain in pre-project planning stages.
The government has established an ambitious target of 100 GW of nuclear energy capacity by 2047, representing approximately a tenfold increase from current operational capacity. This expansion strategy employs a dual approach: deployment of large-capacity reactors like the VVER models at Kudankulam, combined with rapid scaling of SMRs to accelerate power generation capacity additions.
To support this expansion, the Indian government has allocated more than $2 billion for research and development specifically focused on indigenous SMR technology, with an objective of achieving at least five operationally deployed indigenous SMRs by 2033.
