 Why in news

  • Finance Minister Nirmala Sitharaman highlighted nuclear power's role in India’s renewable energy targets for 2024-2025 and 2025-2026.

  • A new addition to the energy mix: Small Modular Reactors (SMRs) are set to play a role in achieving these goals.

What Are SMRs?

  • SMRs are smaller, flexible, and easier to build compared to traditional nuclear reactors, generating less than 300 MW of power.

  • Microreactors, an even smaller design, are being researched to produce 1-20 MW of nuclear power.

Advantages of SMRs

  • SMRs are cheaper to build and safeguard than conventional reactors.

  • Parts of the reactors can be manufactured separately in factories and then transported for assembly, making them more flexible and quicker to deploy.

  • SMRs can be scaled up more easily than larger reactors.

Challenges and Investments

  • SMRs are still experimental, requiring significant capital investment with uncertain profitability.

  • The first-generation SMR designs depend on low-grade uranium as fuel, which means they need to be refueled more frequently, presenting operational challenges.

  • The Indian government has allocated ₹20,000 crore under the 'Nuclear Energy Mission' to study SMRs and develop five operational units by 2033.
