New Delhi (ABC Live): As India moves decisively toward its 100 GW nuclear power target by 2047, Small Modular Reactors (SMRs) have rapidly emerged as a strategic inflection point. Until recently, India’s atomic expansion depended largely on gigawatt-scale reactors. However, rising capital costs, extended construction timelines, and land-acquisition challenges have made that pathway increasingly difficult.

Consequently, policymakers are now turning to SMRs as a flexible, scalable alternative. Against this backdrop, a critical strategic question arises: who is better placed to shape India’s SMR future—the United States or Russia?

This ABC Live Explained report answers that question by examining execution capability, scalability, liability, geopolitics, and industrial integration through a strictly India-centric policy lens.

Why SMRs Matter for India’s Nuclear Transition

Traditionally, nuclear power in India functioned as a mega-project sector. In contrast, SMRs fundamentally alter the economics and deployment logic of nuclear energy.

For instance, SMRs offer:

• Lower upfront capital costs

• Factory-based modular manufacturing

• Shorter construction timelines (typically 3–5 years)

• Greater suitability for industrial clusters, hydrogen hubs, refineries, steel plants, and defence installations

Moreover, SMRs reduce land pressures and grid stress. As a result, nuclear power shifts from a purely baseload role to an industrial decarbonisation tool.

In fact, ABC Live has already shown how SMRs can reshape India’s clean manufacturing and export competitiveness in its earlier explainer, Explained: How India’s SMRs Can Clean Industry and Trade. Taken together, these developments explain why SMRs are now central to India’s energy and trade strategy.

Russia’s SMR Advantage: Execution First

At present, Russia holds a clear advantage in actual SMR deployment.

What Russia Brings

Notably, Russia’s RITM-200 and RITM-400 SMRs are already operational, particularly in nuclear icebreakers and floating nuclear power plants. Additionally, Rosatom’s state-backed model absorbs construction, financing, and nuclear liability risks.

Because of this, Russia has demonstrated an ability to deliver nuclear projects even under challenging geopolitical conditions.

What This Means for India

Therefore, for India, Russian SMRs translate into:

• Faster first-mover deployment

• Lower technological uncertainty

• Immediate applicability in remote regions, islands, and strategic defence locations

In short, if India seeks operational SMRs within the next five to seven years, Russia remains the most execution-ready partner.

The US SMR Advantage: Scale and Ecosystem

While Russia leads in execution, on the other hand, the United States leads in design diversity, industrial scalability, and ecosystem depth.

What the USA Brings

Specifically, the US SMR landscape includes advanced designs such as:

• GE-Hitachi BWRX-300

• NuScale VOYGR

• Westinghouse SMR concepts

Furthermore, US designs emphasise factory manufacturing and fleet-based deployment. As a result, costs fall sharply when SMRs are deployed at scale.

Why This Matters for India

Consequently, US SMRs align closely with:

• Make in India manufacturing objectives

• Large-scale industrial decarbonisation

• Repurposing old coal-based thermal power sites

Thus, if India’s goal is to deploy dozens of SMRs contributing 25–30 GW by 2047, the US model offers superior long-term scalability.

The Liability Constraint: India’s Structural Bottleneck

However, technology alone does not determine outcomes. Equally important is India’s Civil Liability for Nuclear Damage Act.

• Russia, backed by the state, can absorb liability risks more comfortably

• By contrast, US private firms remain cautious without liability caps or government-backed insurance pools

As a result, under the current legal framework, Russian SMRs face fewer immediate entry barriers than US designs.

Technology Sovereignty and Indigenisation

Nevertheless, India’s ambition extends beyond deployment. Ultimately, the objective is technology sovereignty.

Here, the balance shifts:

• US partnerships offer greater scope for joint design, IP sharing, and export-oriented manufacturing

• Conversely, Russian cooperation remains more tightly state-controlled, with limited localisation beyond assembly

Therefore, from an Atmanirbhar Bharat perspective, US SMR ecosystems offer deeper long-term strategic value.

Geopolitics and Sanctions Risk

At the same time, nuclear infrastructure is long-lived. Accordingly, geopolitics cannot be ignored.

• Russia faces sustained sanctions exposure and potential supply-chain uncertainty

• Meanwhile, US cooperation offers easier access to global finance and climate-linked capital

Hence, when planning infrastructure for 2047 and beyond, geopolitical resilience increasingly favours US-linked ecosystems.

Strategic Bottom Line

Ultimately, the choice before India is not binary.

• In the short term, Russia offers speed, certainty, and operational learning

• In the long term, the United States offers scale, industrial integration, and ecosystem depth

Therefore, India’s optimal SMR strategy lies in sequencing rather than substitution:

1. First, deploy Russian SMRs to gain operational experience
2. Next, scale US-designed SMRs for industrial and trade decarbonisation
3. Finally, indigenise both pathways under BARC–DAE oversight
