Conclusion: Provide a conclusion on the use of small modular reactors (SMRs) in India, compared to big plants.


India is taking steps towards the development of Small Modular Reactors (SMRs) with up to 300 MW capacity as part of its commitment to clean energy transition. The participation of the private sector and startups is encouraged to explore the development of this critical technology within India. SMRs offer cost savings, shorter construction time, and flexibility in design, making them a promising technology for industrial decarbonization.

Present the case of the use of small modular reactors (SMRs) in India, compared to big plants:

  • SMR advantages: SMRs are smaller in size and require a smaller footprint compared to conventional nuclear reactors. They can be factory-built, resulting in cost and time savings during construction.
  • Flexibility and scalability: The modular design of SMRs allows for flexible deployment and scalability, making them suitable for a variety of applications and locations, including remote areas and industrial settings.
  • Reliable and continuous power supply: SMRs provide a reliable and continuous supply of power, making them valuable for industrial processes that require consistent energy availability.
  • Safety and simplicity: SMRs are considered simpler and safer than large nuclear plants due to their design and inherent safety features. Their smaller size allows for better control and containment of any potential accidents or incidents.
  • Clean energy transition: SMRs play a significant role in India’s clean energy transition strategy. As a base load power source, nuclear energy, including SMRs, can help in the decarbonization of the energy sector and reduce reliance on fossil fuels.
  • Complementary to renewables: While India has made significant progress in renewable energy adoption, SMRs can complement renewable sources by providing a stable and constant power supply, particularly when intermittent renewable sources are not available.

Way forward:

  • Private sector participation: Encourage the private sector and startups to actively participate in the development and deployment of SMR technology in India. Collaboration between government, industry, and research institutions is crucial for progress.
  • Technology sharing and funding: Foster technology sharing and collaboration with international partners to leverage expertise and resources for the development of SMRs. Ensure sufficient funding mechanisms are in place to support research, development, and commercial availability of SMR technology.
  • Regulatory framework: Establish a clear and comprehensive regulatory framework that addresses safety, security, waste management, and public concerns related to SMR deployment.


Small Modular Reactors (SMRs) offer an innovative and flexible approach to nuclear power generation. In India’s pursuit of a clean energy transition, SMRs can play a significant role due to their smaller size, cost savings, and reliability.
