Technology Sovereignty & Technology Import: Understanding India's Dual-Track Nuclear Market

India's nuclear programme is advancing along two distinct tracks. The first is an indigenous three-stage programme built around thorium, anchored by the Prototype Fast Breeder Reactor (PFBR) at Kalpakkam and supported by nearly six decades of domestic reactor design and manufacturing capability. The second is an import track through which foreign reactor technologies, including France's EPR and Russia's VVER-1200, are being evaluated for deployment in India. These tracks operate in parallel and serve the same capacity target of 100 GW by 2047. For international vendors, the commercial significance lies in understanding that the import track exists to accelerate capacity addition, not to create long-term technological dependence.

The Indigenous Track: Institutional Depth and Technical Sovereignty

The foundation of India's nuclear programme is the three-stage plan proposed by Homi J. Bhabha in 1954. Stage One uses Pressurised Heavy Water Reactors (PHWRs) running on natural uranium. Stage Two, now operational following the PFBR's first criticality in April 2026, uses plutonium-based fuel in fast breeder reactors to breed additional fissile material and produce uranium-233 from thorium. Stage Three will deploy thorium-based reactors to use India's thorium reserves, which account for roughly 25 per cent of the world's identified supply.

The state layer responsible for this programme is the Nuclear Power Corporation of India Limited (NPCIL), which manufactures a substantial share of components domestically and operates without dependence on a foreign technology licensor for its core fleet. The Indira Gandhi Centre for Atomic Research (IGCAR) led the design, development, testing, safety assessment and commissioning of the PFBR, achieving nearly 90 per cent domestic manufacturing of the reactor's equipment and systems.

This institutional depth changes the terms on which private participation occurs. Companies entering through the SHANTI Act's joint venture and independent power producer provisions are not required to source or develop reactor technology. NPCIL is positioned to provide standard specifications and engineering guidelines for the 220 MWe and 700 MWe PHWR designs. Private participants are being asked to build, finance and operate a defined product at scale. Technology risk is therefore lower than in markets where a private entrant must also manage technology acquisition and licensing from the beginning.

The Import Track: Foreign Reactors as Capacity Accelerants

The 100 GW target is too large for the state layer alone. India currently operates 24 reactors with 8.78 GW installed capacity, and nine units with a combined 7.5 GW are under construction. The roadmap to 100 GW by 2047 requires 22 GW by 2031-32 from ongoing projects, followed by contributions from Department of Atomic Energy units and joint ventures, other implementing agencies, central and state public sector enterprises, state governments, the private sector and joint ventures using diverse reactor technologies.

Foreign reactor technology is being evaluated within this framework. Senior officials from India and France reviewed ongoing engagement on the proposed deployment of EPR technology in India. The discussions involved India's Ministry of Power, Ministry of External Affairs, Central Electricity Authority, NTPC and NPCIL, with the French delegation including representatives from EDF and the Embassy of France in India. The two sides examined the proposed deployment of EPR technology alongside India's regulatory reforms for the nuclear sector.

On the Russian side, Rosatom is in talks with Adani Group, Reliance, Jindal and NTPC regarding participation in India's nuclear programme. Kirill Komarov, First Deputy Director General for Corporate Development and International Business at Rosatom, confirmed these discussions. Rosatom has already reached 50 per cent localisation at Kudankulam in Tamil Nadu and has stated its readiness to replicate that model with new Indian companies entering the sector.

The Regulatory Bridge: SHANTI Act and Draft Rules

The SHANTI Act, 2025, replaced the Atomic Energy Act of 1962 and the Civil Liability for Nuclear Damage Act of 2010. It ended NPCIL's monopoly on operating nuclear power plants and permitted private companies including Adani, Tata Power, Jindal Nuclear, Vedanta and Reliance Industries to construct, own, operate and decommission nuclear plants. Foreign direct investment of up to 49 per cent is permitted, and the supplier liability clause that had kept Western vendors at a distance has been removed.

The Draft SHANTI Rules and Regulations provide for a streamlined and time-bound licensing framework for nuclear power projects. They enable the participation of private and foreign partners in India's nuclear power programme. The Department of Atomic Energy has placed the draft in the public domain for stakeholder consultation. The regulatory framework is designed to support foreign reactor deployment while maintaining Indian control over programme direction and long-term fuel-cycle strategy.

Commercial Implications for Foreign Vendors

Foreign vendors entering India are not entering a blank slate. The state layer provides the technical foundation, the site selections and the regulatory pathway. Private Indian companies provide capital, construction capacity and operational discipline. The counterparty landscape for joint ventures, technology partnerships and supply agreements is diversified across multiple private entities with different strategic priorities. A technology vendor partnering with Tata Power is building a different relationship than one partnering with Adani or Jindal.

Rosatom's emphasis on localisation captures the commercial logic. Komarov stated that for such an ambitious programme, India needs to be able to not only import equipment and materials but also produce a majority of these things in India. He described localisation as the key element of success for India's programme. This positions foreign vendors as technology partners who supply proven reactor designs while simultaneously building Indian manufacturing capacity for components, systems and fuel-cycle services.

Strategic Balance

India's two tracks are complementary instruments. The indigenous programme provides long-term fuel security and positions India as a potential technology exporter in thorium-based reactor designs. The import track provides proven large-reactor technology to accelerate capacity addition toward the 100 GW target while domestic manufacturing and supply chains scale up.

Foreign vendors that structure their India entry around localisation, joint ventures with private Indian counterparties and long-term supply-chain integration will find a market that needs their reactor technology but does not intend to depend on them permanently. The state layer remains the anchor of the programme, and the regulatory framework is designed to ensure that foreign participation strengthens indigenous capability rather than substituting for it.
