Make in India Meets Nuclear Power: Opportunities for Suppliers and Manufacturers
India has 24 operating nuclear reactors producing 8.78 GW, with nine more under construction. The government's target is 100 GW by 2047. A build-out of that size is a manufacturing story as much as an energy one. The Press Information Bureau describes the Nuclear Energy Mission and the SHANTI Act of 2025 as measures that strengthen domestic manufacturing, promote innovation, and enable greater private sector participation. For equipment makers and foreign technology partners, the practical question is where the orders will come from. The sources point to four places.
A Proven Product That Is Being Repeated
India's state nuclear utility, NPCIL, has built its fleet around Pressurised Heavy Water Reactors that India developed indigenously. NPCIL owns these designs outright, manufactures a substantial share of the components domestically, and does not depend on a foreign licensor for its core fleet. The government has now approved 10 further indigenous PHWRs in fleet mode, meaning units built as a series rather than one at a time.
Series construction suits manufacturers. A repeated design means repeated component orders to a known specification. Under the SHANTI Act, NPCIL is positioned to give incoming private participants standard specifications and engineering guidelines for its 220 MWe and 700 MWe PHWR designs. Private entrants are being asked to build, finance, and operate a defined product, not to develop reactor technology. For a manufacturer, that offers a clear specification to build to and a pipeline of identical units to build it for.
Nearly Half of the Target Is Still Open
The roadmap to 100 GW has three parts. Ongoing projects are expected to reach 22 GW by 2031-32. Another 32 GW is assigned to units and joint ventures of the Department of Atomic Energy. The remaining 46 GW is assigned to other implementing agencies, a group that includes central and state public sector enterprises, state governments, the private sector, and joint ventures, using diverse reactor technologies.
That last bucket is almost half of the total, and it is where the supplier map is least settled. The phrase "diverse reactor technologies" reads as an invitation to a range of vendors, each with its own equipment needs. Foreign vendors entering that space will need Indian manufacturing partners, and Indian manufacturers will find a wider choice of technology partners than the state fleet alone offers.
New Private Customers With Different Strengths
The SHANTI Act allows private companies to construct, own, operate, and decommission nuclear plants. Foreign direct investment of up to 49% is permitted, and the supplier liability clause that had kept Western vendors at arm's length has been removed. Adani, Tata Power, Jindal Nuclear, Vedanta, and Reliance Industries are all named as potential entrants.
These groups bring different strengths, and that matters to anyone selling into the sector. Jindal's materials and manufacturing base positions it for supply chain integration as much as for power generation. Tata Power, with its execution depth and international technology partnerships, is likely to pursue a joint venture with a global reactor vendor. Adani appears to be building its entry around specific sites. For a manufacturer, each of these is a new type of customer or partner. For a foreign firm, choosing among them on strategic fit, rather than availability, is one of the most important decisions of the next two years.
Factory-Built Reactors and Advanced Equipment
India's small modular reactor programme adds a different kind of manufacturing demand. Under the Nuclear Energy Mission announced in the Union Budget 2025-26, the government has allocated ₹20,000 crore for research, design, development, and deployment of indigenous SMRs. Designs under development include the 220 MWe Bharat Small Modular Reactor, jointly designed by BARC and NPCIL, the 55 MWe SMR-55, and a high-temperature gas-cooled reactor for hydrogen production. The stated aim is at least five indigenous SMRs in operation by 2033. SMRs are built largely in factories, which makes them a natural fit for industrial manufacturers that can produce modules to tight quality standards.
India has also shown what its industry can deliver on advanced equipment. The Prototype Fast Breeder Reactor at Kalpakkam reached first criticality in April 2026, and its designers report that nearly 90% of its equipment and systems were manufactured domestically, through close collaboration with Indian industry. Two 500 MW fast breeder reactors are now in pre-project stage. That track record is relevant to any foreign firm weighing whether Indian suppliers can meet demanding specifications.
What This Means for Indian Manufacturers and Foreign Partners
For Indian manufacturers, three steps follow from the sources. First, understand NPCIL's standard PHWR specifications, since fleet-mode construction will repeat them. Second, approach the private groups early, because each is assembling its supply chain and partnerships now. Third, look at modular components for the SMR programme, where factory production is central to the plan.
For foreign firms, the structure of the market points toward joint ventures. Foreign equity is permitted up to 49%, which makes an Indian partner a necessary part of any plant-owning structure. Vendor discussions are already under way. In a recent meeting, officials from India's Ministry of Power, Central Electricity Authority, NTPC, and NPCIL reviewed the proposed deployment of EPR technology with EDF and the French Embassy. Foreign vendors and Indian manufacturers have good reason to talk well before contracts are written.
The Rulebook Is Still Open
The draft SHANTI Rules and Regulations, which provide for a streamlined and time-bound licensing framework and enable private and foreign participation, have been placed in the public domain by the Department of Atomic Energy for stakeholder consultation. Partnerships formed while that consultation is open will help determine who supplies what once the rules are final. The 100 GW target gives the market its size. The next two years will show which manufacturers and partners have positioned themselves to serve it. For a deeper assessment of entry pathways, the India Nuclear Industry Report 2026 provides the detailed mapping.
