India’s push to build indigenous Small Modular Reactors (SMRs) has turned the spotlight on a handful of listed engineering and capital goods companies that already form part of the country’s nuclear supply chain.
The government is working to operationalise at least five SMRs by 2033 as part of its plan to raise nuclear power capacity to 100 GW by 2047 from around 8.8 GW at present, according to a Reuters report.
India’s small modular reactor: The key details
The Bhabha Atomic Research Centre (BARC) is developing three indigenous reactor designs – the 220 MW Bharat Small Modular Reactor (BSMR-200), the 55 MW SMR and a high-temperature gas-cooled reactor for hydrogen production.
Tarapur in Maharashtra has been approved as the site for the 220 MW and 55 MW reactors, with engineering, manufacturing and construction expected to gather pace over the coming years.
Only a limited number of Indian companies manufacture nuclear-grade equipment or have experience in executing reactor projects. BHEL, Larsen & Toubro, MTAR Technologies, Hindustan Construction Company, Kirloskar Brothers and Walchandnagar Industries are among the listed names with established capabilities across reactor equipment, precision engineering and specialised construction.

BHEL: One of the key potential beneficiaries
Bharat Heavy Electricals has supplied equipment to India’s nuclear power programme for decades and remains one of the country’s largest manufacturers of steam generators, reactor headers, turbine-generator systems, end shields and heat exchangers used in nuclear plants. Its manufacturing capabilities place it among the companies best positioned to benefit as indigenous SMRs move towards commercial deployment.
The stock has also been among the strongest performers in the engineering space. Shares ended at Rs 417.50 on July 24, rising 68.55% over the past six months, up43.25% so far in 2026 and 66.30% over the past year. Over the last five years, the stock has surged 552.85%.

Conclusion
For listed companies, the opportunity is likely to emerge over several years rather than immediately. BHEL, L&T, MTAR Technologies, HCC, Kirloskar Brothers and Walchandnagar Industries already have capabilities across different parts of the nuclear supply chain, while NTPC and Engineers India are positioned on the project development and engineering side.
As project timelines become clearer and fresh orders are awarded, these companies are likely to remain on investors’ radar.
