India Opens Nuclear Power Sector to Proven Foreign Technology Under Proposed New Approval Regime

India Opens Nuclear Power Sector to Proven Foreign Technology Under Proposed New Approval Regime

India is preparing a major change in the way foreign nuclear technology can enter its civil nuclear power market, with draft rules under the SHANTI Act proposing a regulatory pathway for proven reactor technologies from eligible overseas partners. The framework is designed to combine private-sector participation, international technology collaboration and stricter lifecycle regulation as India pursues its ambitious target of 100 GW of nuclear power capacity by 2047. The proposed regime could reshape investment in one of the country's most tightly controlled infrastructure sectors while maintaining safeguards around safety, technology and energy security.

Draft Nuclear Rules Create New Technology Approval Pathway

The proposed framework represents the next stage of India's nuclear-sector reforms following the enactment of the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India Act, 2025.

Proven Foreign Reactor Technology Could Enter India

Under the proposed rules, Indian nuclear developers could potentially use proven reactor technologies developed outside the country, subject to regulatory and government requirements.

The framework is expected to prioritise technology originating from countries with established and self-reliant capabilities in nuclear reactor design and associated supply chains.

This distinction is important.

India is not proposing unrestricted access for any reactor technology available internationally. The emphasis is on technologies with demonstrated operational experience and credible industrial support.

Such an approach could reduce technology risk while giving Indian developers access to reactor designs already validated in other nuclear markets.

It could also expand the technology options available as India attempts to increase nuclear capacity at an unprecedented pace.

Regulatory Approval Would Remain Essential

Foreign technology would not automatically qualify for deployment simply because it has operated successfully elsewhere.

Reactor designs would still need to satisfy India's regulatory requirements.

The Atomic Energy Regulatory Board would continue to have a central role in nuclear safety oversight.

Indian regulators would need to assess factors including reactor design, safety systems, site conditions, operational requirements and emergency preparedness.

This preserves an important distinction between opening the market to international technology and weakening regulatory control.

Nuclear plants operate for several decades, making the initial technology approval process critical to long-term safety and performance.

Single Composite Licence Could Simplify Nuclear Projects

One of the most significant elements of the draft framework is the proposed movement toward a more integrated licensing system.

Licence Could Cover Entire Nuclear Plant Lifecycle

The draft rules envisage a single composite licence covering multiple stages of a nuclear project's lifecycle.

This could extend from construction and commissioning through operation and eventual decommissioning.

A more integrated system could make regulatory responsibilities clearer for developers.

Nuclear projects currently require extensive approvals because they involve complex safety, environmental, security and technical considerations.

Streamlining the administrative structure does not necessarily mean reducing safety requirements.

Instead, the objective is to create a clearer regulatory pathway through which developers understand their obligations throughout the life of the project.

Greater predictability could become particularly important as private companies enter the sector.

Long-Term Responsibilities Remain With Operators

Nuclear power plants create responsibilities extending far beyond the construction period.

Operators need to maintain safety systems, manage nuclear materials, handle waste and eventually decommission facilities.

The proposed lifecycle approach reflects these long-term obligations.

Private developers considering nuclear investments therefore need to evaluate project economics over several decades rather than focusing only on construction expenditure.

Decommissioning costs and financial security arrangements can become material considerations.

This makes nuclear infrastructure fundamentally different from many conventional power projects.

The new framework will need to ensure that companies entering the sector have both the technical capability and financial strength required to meet these obligations.

SHANTI Act Changes India’s Nuclear Investment Model

India's nuclear sector was historically dominated by government-controlled entities because of legal restrictions surrounding atomic energy.

Private Companies Can Enter Nuclear Power Development

The SHANTI Act represents a structural change by enabling wider public and private participation.

Private companies will be able to seek licences once the implementing rules are finalised and notified.

This could bring substantial new pools of capital into the sector.

Large Indian industrial groups have already begun evaluating opportunities.

Companies considering nuclear investments include businesses with significant experience in power generation, infrastructure and heavy industry.

Private participation could reduce the burden on government-owned companies to finance the entire nuclear expansion programme.

However, nuclear power requires substantially different expertise from conventional thermal or renewable generation.

New entrants will therefore need specialist technical partners, experienced personnel and robust safety systems.

Foreign Companies Could Participate Through Technology Partnerships

The reforms could also create new commercial opportunities for international nuclear companies.

Foreign reactor developers have long viewed India as a potentially enormous market.

Actual project development, however, has been constrained by regulatory, liability and commercial issues.

The new framework could enable foreign companies to participate more effectively through technology partnerships with eligible Indian developers.

Their role could include reactor technology, engineering, specialised equipment and technical services.

This model would allow India to access global expertise while maintaining domestic control over strategically sensitive nuclear infrastructure.

India Targets 100 GW of Nuclear Capacity by 2047

The regulatory reforms are closely connected to the Nuclear Energy Mission announced as part of India's long-term development strategy.

Current Nuclear Capacity Is Below 9 GW

India currently has approximately 8.78 GW of installed nuclear power capacity.

The government aims to increase this to around 22 GW by 2031-32 as projects already under development progressively enter service.

The longer-term target is considerably more ambitious.

India wants nuclear power capacity to reach 100 GW by 2047.

Achieving that target would require adding more than 90 GW over roughly two decades.

Such expansion would be difficult to deliver through the existing public-sector model alone.

Private investment, standardised reactor construction and international technology partnerships could therefore become important components of the strategy.

Nuclear Power Supports India’s Clean Energy Transition

India's electricity demand is expected to increase substantially as the economy expands.

Renewable energy will provide a growing share of generation, but solar and wind production varies with weather and time of day.

Nuclear plants can provide large quantities of low-carbon electricity on a continuous basis.

This makes nuclear energy potentially complementary to renewable generation.

A larger nuclear fleet could reduce dependence on coal while supporting electricity demand from manufacturing, transport electrification, urbanisation and digital infrastructure.

India has also committed to achieving net-zero emissions by 2070.

Nuclear expansion is therefore being positioned simultaneously as an energy-security, industrial-development and decarbonisation strategy.

Proven Technology Could Reduce Development Risk

Building a nuclear reactor based on an established design can provide advantages compared with deploying an entirely untested system.

Operating History Provides Important Safety Evidence

Nuclear technology is evaluated over extremely long periods.

A reactor that has accumulated substantial operating experience provides regulators and developers with real-world information about performance.

Operational history can reveal maintenance requirements, component behaviour and other engineering characteristics.

This does not eliminate project risk.

Local geological conditions, climate, grid requirements and regulatory standards can still require substantial adaptation.

However, using proven technology can reduce some of the uncertainty associated with completely new reactor designs.

For private developers committing billions of dollars to a project, this track record can be commercially important.

Standardisation Could Lower Construction Costs

Nuclear economics can improve when multiple reactors use standardised designs.

Repeated construction allows suppliers and project teams to build experience.

Manufacturing processes can become more efficient, while engineering work completed for one reactor can potentially be reused across subsequent projects.

India has already pursued fleet-mode construction of its indigenous 700 MW Pressurised Heavy Water Reactors.

A similar approach could potentially be applied to selected foreign technologies if they receive approval and sufficient projects are developed.

Standardisation could be particularly important for meeting the 100 GW target because building numerous one-off reactor designs would increase complexity across the supply chain.

Indigenous Technology Remains Central to Nuclear Strategy

Opening the sector to foreign technology does not mean India is abandoning domestic reactor development.

PHWR Programme Will Continue Expanding

India's indigenous Pressurised Heavy Water Reactor programme remains a major component of its nuclear strategy.

The 700 MW PHWR design is expected to contribute significantly to future capacity additions.

Domestic companies already supply substantial equipment and engineering services to these projects.

Industry organisations have called for clearer mechanisms allowing private developers to access indigenous PHWR technology.

Such arrangements could create another route for private nuclear investment alongside foreign technology partnerships.

This means India's future reactor fleet could include a combination of domestically developed PHWRs, foreign-origin designs and emerging small modular reactor technologies.

Three-Stage Nuclear Programme Remains Strategically Important

India is also continuing its long-standing three-stage nuclear programme.

The strategy is designed around the country's available uranium and large thorium resources.

The first stage uses Pressurised Heavy Water Reactors.

The second stage involves fast breeder reactors capable of using plutonium generated from spent fuel.

The third stage is intended to make greater use of thorium through uranium-233.

India reached an important milestone in April 2026 when its indigenous 500 MW Prototype Fast Breeder Reactor at Kalpakkam achieved first criticality.

The achievement reinforces the government's position that foreign technology should complement rather than replace indigenous nuclear capabilities.

Small Modular Reactors Could Create Another Investment Market

The nuclear reforms arrive as India also develops a new generation of smaller reactor technologies.

Five Indigenous SMRs Are Targeted by 2033

India's Nuclear Energy Mission aims to develop and operationalise at least five indigenous small modular reactors by 2033.

BARC is working on multiple designs.

These include the 220 MWe Bharat Small Modular Reactor and a 55 MWe small modular reactor.

A high-temperature gas-cooled reactor is also being developed for applications including hydrogen production.

SMRs are attracting global attention because their smaller size could allow more standardised manufacturing and potentially lower upfront project costs.

They could also serve industrial applications that do not require a conventional gigawatt-scale nuclear station.

Industrial Users Could Become Nuclear Customers

Small reactors could potentially supply electricity and heat directly to industrial facilities.

Steel, chemicals, refining and other energy-intensive sectors need reliable power while facing increasing pressure to reduce emissions.

A smaller reactor located near an industrial cluster could provide continuous low-carbon energy.

Such applications could expand the nuclear market beyond conventional electricity utilities.

Private-sector participation becomes particularly relevant in this context because large industrial groups may want to secure dedicated clean-energy supplies for their own operations.

The regulatory framework will need to address these emerging business models as reactor technology evolves.

Liability and Insurance Remain Critical Issues

Nuclear investment depends heavily on clarity about financial responsibility in the event of an accident.

SHANTI Framework Establishes Operator Liability

The new legal framework includes provisions governing civil liability for nuclear incidents.

Operator liability varies according to the category and scale of the nuclear installation.

For the largest reactors, the operator liability ceiling can reach ₹3,000 crore under the framework.

The overall liability for a nuclear incident is linked to the rupee equivalent of 300 million Special Drawing Rights unless otherwise specified by the government.

Developers must therefore incorporate liability exposure into project financing and insurance arrangements.

These provisions are especially important for private companies entering nuclear generation for the first time.

Foreign Suppliers Need Predictable Liability Rules

Liability has historically been one of the most closely watched issues for international nuclear suppliers considering the Indian market.

Nuclear companies need clarity about potential financial exposure before committing technology and equipment to multibillion-dollar projects.

Greater predictability could improve the commercial viability of international partnerships.

However, the framework must simultaneously protect public interests and ensure adequate financial resources are available if an incident occurs.

Finding the appropriate balance between investment attractiveness and accountability will remain central to implementation of the new regime.

Global Nuclear Companies Could Gain a Major New Market

India's planned expansion could create one of the world's largest nuclear investment opportunities.

International Reactor Developers Could Revisit India

Global nuclear companies have previously pursued Indian projects with limited progress.

The new policy environment could encourage renewed engagement.

Companies with established reactor technologies may explore partnerships with Indian power producers and industrial groups.

Competition between international suppliers could benefit India by creating stronger negotiating leverage over pricing, technology transfer and localisation.

The government can also evaluate technologies according to operating performance rather than depending on a single overseas supplier.

However, geopolitical considerations will remain important because nuclear technology is strategically sensitive and subject to international controls.

Local Manufacturing Could Be Required at Scale

India's nuclear expansion cannot depend indefinitely on importing complete reactor systems.

Building dozens of reactors would create substantial demand for heavy engineering, specialised steel, pumps, valves, control systems and other components.

Localising these supply chains could reduce costs and strengthen energy security.

Foreign technology partnerships may therefore need to include significant Indian manufacturing.

This could create opportunities for domestic engineering companies and specialised suppliers.

Over time, India could potentially develop manufacturing capabilities capable of serving both domestic projects and international nuclear markets.

Private Capital Could Transform Nuclear Project Financing

Reaching 100 GW will require enormous capital expenditure.

Nuclear Plants Require Large Upfront Investment

Nuclear power plants are capital intensive.

Construction can require several years before a project begins generating revenue.

Delays can significantly increase financing costs.

This has historically made nuclear development challenging even in advanced economies.

Private developers will therefore require financing structures capable of supporting long construction periods.

Power-purchase agreements, government support mechanisms and predictable tariffs could influence whether projects become commercially viable.

The proposed regulatory reforms address licensing, but investment decisions will ultimately depend on project economics.

Policy Certainty Will Determine Investor Appetite

Private companies can commit capital only when they understand the regulatory and commercial framework.

Developers will need clarity on licensing, liability, fuel supply, waste management, decommissioning and electricity offtake.

They will also evaluate whether returns adequately compensate for construction and operational risks.

The draft rules are therefore an important step rather than the final requirement for large-scale private investment.

Implementation will determine whether India's nuclear reforms translate into actual projects.

Nuclear Expansion Could Strengthen Energy Security

Energy security is one of the central arguments supporting India's nuclear strategy.

Nuclear Power Reduces Dependence on Fossil Fuels

India imports significant quantities of crude oil, natural gas and coal.

Greater nuclear generation can reduce the need for fossil-fuel-based electricity as demand increases.

Nuclear plants also require relatively small volumes of fuel compared with the enormous quantities of coal consumed by thermal power stations.

India nevertheless faces uranium-supply challenges.

Domestic uranium production currently covers only part of the requirements of the PHWR fleet, making diversified fuel supplies and development of domestic resources important.

The country's three-stage nuclear programme is ultimately designed to exploit its large thorium reserves and strengthen long-term fuel security.

Diversified Reactor Technologies Can Reduce Concentration Risk

Using multiple proven technologies could reduce dependence on any single foreign supplier.

India can combine domestic reactor designs with selected international technologies according to project requirements.

Diversification also creates competitive pressure among suppliers.

However, operating many unrelated reactor designs can increase maintenance and supply-chain complexity.

Policymakers will therefore need to balance technological diversification against the economic advantages of standardisation.

Selecting a limited number of scalable reactor platforms could offer a practical middle path.

Conclusion

India's proposed approval regime for proven foreign nuclear technology represents a major step in the transformation of its civil nuclear power sector. Combined with the SHANTI Act's opening for wider private participation, the framework could bring new capital, international reactor technology and greater competition into an industry historically dominated by government entities.

The reforms are closely connected to India's target of expanding nuclear capacity from about 8.78 GW today to 100 GW by 2047.

Foreign technology alone will not deliver that expansion. Project financing, regulatory implementation, liability arrangements, domestic manufacturing and fuel security will all remain critical.

If India can combine proven international reactor technologies with its indigenous PHWR, fast breeder and emerging SMR programmes, the country could build a significantly larger and more diversified nuclear industry while strengthening long-term energy security and low-carbon electricity generation.
