Why Nuclear Power Stocks Are Back In Focus After Customs Duty Relief
Nuclear power stocks are back in focus after the government waived customs duty on specified nuclear imports, supporting India's long-term nuclear expansion plans and improving cost visibility for the sector.
Quick Summary
Nuclear power stocks are back in focus after customs duty relief on nuclear imports. The move supports India's nuclear expansion plans and has put companies like MTAR Tech, BHEL, L&T, and Walchandnagar in the spotlight.
Nuclear power stocks are back on the market radar after the government removed a major cost uncertainty for nuclear power imports.
The Ministry of Finance has waived customs duty on specified goods imported for nuclear power generation for the period between 1 April 2019 and 31 January 2026. The move covers goods such as non-irradiated fuel elements and cartridges used in nuclear reactors.
This is important because the exemption does not only apply going forward. It also regularises past imports, which means importers will not have to face retrospective duty demands for the covered period.
The direct beneficiary is Nuclear Power Corporation of India Ltd, which operates India’s nuclear reactor fleet. NPCIL is unlisted. But the stock market reaction has listed companies that are part of the broader nuclear power supply chain.
Nuclear Power Stocks In Focus
Here are some of the best nuclear power stocks in India that you should track:

Why The Duty Waiver Matters
Customs duty relief can reduce the cost burden on nuclear power projects.
Nuclear projects involve large upfront investment, specialised imports and long execution timelines. When import duties are removed or clarified, project cost estimates become easier to manage. This can support project viability and reduce uncertainty for entities involved in nuclear power generation.
The latest notification also solves a past-period issue. Imports made between April 2019 and January 2026 will now not attract retrospective duty payment for the specified nuclear goods.
Why The Stock Market Reacted
The rally in nuclear-linked stocks is not only about one customs notification.
It is also about India’s larger nuclear power push. The government has already set a target to increase nuclear power capacity to 100 GW by 2047. The present nuclear power capacity is expected to rise from 8.78 GW to about 22 GW by 2031-32 as projects under implementation are completed.
That creates a longer-term opportunity for companies involved in nuclear equipment, reactor components, heavy engineering, turbines, civil construction and project execution.
For nuclear-listed companies, the market is looking at three things. First, whether nuclear project orders increase over time. Second, whether companies with existing nuclear capabilities get more work as capacity expansion picks up.
Third, whether better policy clarity improves execution visibility for the entire nuclear supply chain.

Why Every Stock May Not Benefit Equally
The nuclear power theme is not the same for every company.
MTAR Technologies and Walchandnagar Industries are more directly linked to specialised nuclear components and equipment.
Larsen & Toubro and BHEL are larger engineering and power-sector companies, where nuclear is only one part of a much wider business.
Hindustan Construction Company and Power Mech Projects are more linked to project execution and infrastructure work, so their benefit depends on actual contract wins and execution progress.
That is why the market may track specialised nuclear suppliers differently from diversified infrastructure companies.
What Could Be The Risk
The main risk is that the duty waiver itself does not create immediate revenue for listed companies.
It improves cost clarity and supports the nuclear power ecosystem, but stock-specific benefits will depend on fresh orders, project execution, margins and working capital.
Nuclear projects also have long timelines. Approvals, safety requirements, technology tie-ups, fuel supply and project funding can affect the pace of execution.
Conclusion
Nuclear power stocks in India are back in focus because the government’s customs duty relief has removed a key cost uncertainty and supported the larger nuclear expansion theme.
The direct benefit goes to nuclear power project importers, mainly NPCIL. But listed companies in nuclear equipment, heavy engineering, construction and project execution may remain closely tracked as India moves toward its 100 GW nuclear power target.
