India-US Nuclear Cooperation and the Future of SMRs

Source: The post “India-US Nuclear Cooperation and the Future of SMRs” has been created, based on “India’s pitch to US nuclear mission: Scale up capacity, small modular reactors key” published in “Indian Express” on 21st May 2026.

UPSC Syllabus: GS Paper-2- Governance

Context: India and the United States are strengthening cooperation in the civil nuclear energy sector after the passage of the SHANTI Act, 2025. India aims to increase nuclear power generation to improve energy security and clean energy capacity. Small Modular Reactors (SMRs) are emerging as a major area of cooperation between India and the United States.

India–US Nuclear Cooperation

1. Strengthening Strategic Partnership

1. A high-level American nuclear industry delegation recently visited India to explore opportunities in the nuclear sector.
2. The United States has expressed strong interest in participating in India’s expanding nuclear energy programme.

2. Technology Transfer and Regulatory Cooperation

1. Several American nuclear companies have received special authorisations under “10CFR810” regulations.
2. These authorisations allow the transfer of nuclear technology to Indian entities under specific conditions.
3. This step has improved technological cooperation between the two countries.

Role of the SHANTI Act, 2025

1. The SHANTI Act, 2025 opened India’s nuclear sector to private participation for the first time.
2. The Act allowed private players to participate in plant operations and fuel management activities.
3. The reforms created a favourable environment for foreign investment and international collaboration.

Future of Small Modular Reactors (SMRs)

Importance of SMRs

1. Small Modular Reactors are compact nuclear reactors with lower power generation capacity than conventional reactors.
2. SMRs are designed for modular manufacturing and gradual deployment.
3. SMRs are increasingly considered commercially competitive in the global nuclear energy market.

Benefits of SMRs for India

1. Lower Capital Costs: SMRs require lower initial investment compared to large Light Water Reactors (LWRs). Lower project costs can reduce the burden of high electricity tariffs.
2. Flexible Deployment: SMRs can be installed gradually according to regional energy demand. They are suitable for remote areas and industrial clusters.
3. Energy Security: SMRs can strengthen India’s base-load electricity generation capacity. They can support India’s transition towards clean and reliable energy sources.
4. Manufacturing Opportunities: India aims to enter the global manufacturing value chain of SMRs.Foreign collaboration can help India develop advanced manufacturing capabilities.

Challenges in India–US Nuclear Cooperation

1. High Cost of Conventional Nuclear Projects

1. Imported Light Water Reactors involve very high project costs.
2. High capital expenditure increases the final cost of electricity generation.

2. Liability Concerns

1. Earlier liability provisions had discouraged foreign nuclear suppliers from investing in India.
2. The SHANTI Act diluted supplier liability provisions, leading to criticism from the Opposition.

3. Safety and Regulatory Concerns

1. Nuclear energy projects require strict safety standards and effective regulation.
2. Increased private participation may raise concerns regarding accountability and safety oversight.

4. Protection of Indigenous Technology

1. India wants to ensure that foreign collaboration does not weaken its indigenous PHWR technology.
2. The government continues to prioritise domestic reactor design and manufacturing capabilities.

Conclusion: India–US nuclear cooperation is entering a new phase with greater private participation and foreign investment opportunities. Small Modular Reactors offer significant potential for clean energy generation, technological advancement, and industrial growth. However, India must balance foreign collaboration with safety concerns, affordability, and protection of indigenous nuclear capabilities.

Question: “India–US nuclear cooperation has gained new momentum after the passage of the SHANTI Act, 2025.” Discuss the significance of Small Modular Reactors (SMRs) in India’s nuclear energy strategy. Also examine the challenges associated with foreign collaboration and private participation in the nuclear sector.
