List of Top Nuclear Power Stocks in India (2025)

What are Nuclear Power Stocks?

Nuclear power stocks are shares of companies that are involved in the nuclear energy value chain. This includes companies that supply engineering and construction services for nuclear power plants, manufacture critical reactor components such as turbines, pumps, and valves, provide specialist materials or precision-machined parts, and those with direct stakes in nuclear power generation through joint ventures or subsidiaries.

Overview of Top Nuclear Energy Stocks in India

NTPC Ltd

NTPC Ltd is India's largest power generation company, operating across thermal, hydro, solar, wind, and nuclear energy segments. In the nuclear sector, NTPC entered into a joint venture with NPCIL called ASHVINI, which will build, own, and operate nuclear power plants in India. The JV's first project is the 4x700 MWe PHWR Mahi-Banswara Rajasthan Atomic Power Project.

Bharat Heavy Electricals Ltd (BHEL)

BHEL is a public sector engineering and manufacturing company and India's most established nuclear equipment supplier. The company has supplied turbine generator sets to 14 of India's 24 operating nuclear reactors, contributing approximately 50% of India's installed nuclear turbine capacity.

Larsen and Toubro Ltd (L&T)

Larsen and Toubro is a diversified engineering, construction, and technology conglomerate and one of the most diversified plays in the nuclear energy stocks list. L&T manufactures reactor pressure vessels, steam generators, end shields, calandria, pressurisers, and other critical nuclear components. The company operates a joint venture heavy forge unit at Hazira in Gujarat with NPCIL for forging reactor pressure vessels for the Indian Pressurised Water Reactor (IPWR) programme.

MTAR Technologies Ltd

MTAR Technologies is a high-precision engineering company that manufactures critical components for India's nuclear programme. Its nuclear-related products include reactor core components, fuel machining heads, bridge and column systems, coolant channel assemblies, and drive mechanisms for Pressurised Heavy Water Reactors.

Hindustan Construction Company Ltd (HCC)

Hindustan Construction Company is the civil contractor that built approximately 60% of India's nuclear power capacity, including plants at Tarapur, Kakrapar, Narora, and Kudankulam. As new nuclear plant construction accelerates across India over the coming decade, HCC is well-positioned to remain a primary civil contractor.

Government Policy and Budget Support for the Nuclear Power Sector

1. Nuclear Energy Mission (Union Budget 2025-26): Finance Minister Nirmala Sitharaman announced a Nuclear Energy Mission in Budget 2025-26 with a total outlay of ₹20,000 cr. The mission targets the design, development, and deployment of Small Modular Reactors (SMRs) and aims to operationalise at least five indigenously designed SMRs by 2033.
2. 100 GW Target by 2047: India has set an ambitious target of reaching 100 GW of nuclear power capacity by 2047, up from the current 8.8 GW. The government plans to add 22 GW by 2032 through NPCIL using indigenous PHWRs and LWRs, with the remaining capacity to be developed through public sector enterprises, state governments, private players, and joint ventures.
3. 10 New Indigenous 700 MW PHWR Reactors: The government has approved 10 new fleet-mode indigenous 700 MW PHWR reactors for construction. BHEL has already won the turbine island package contract for six of these, and L&T is involved in the civil and structural engineering supply chain for these projects.
4. SMR Development Programmes: BARC is developing three indigenous SMR designs: the 220 MWe Bharat Small Modular Reactor (BSMR-200), the 55 MWe SMR-55, and a high-temperature gas-cooled reactor for hydrogen generation. The BSMR-200 and SMR-55 are planned for construction at the DAE site at Tarapur. These programmes are expected to benefit precision engineering companies in the nuclear supply chain.

Conclusion

India’s nuclear power sector is gaining attention as the country targets 100 GW capacity by 2047. Policy support, rising power demand, and private sector participation can create opportunities for nuclear-linked companies. However, listed stocks primarily provide indirect exposure, so project execution, order flow, approvals, and valuations remain important to monitor.
