India Developing 3 Types of Small Modular Reactors, Govt Tells Lok Sabha

Why It Matters

The SMR programme diversifies India’s energy mix, accelerates low‑carbon power, and positions the country as a hydrogen‑export hub. Successful deployment could reshape domestic nuclear policy and attract international investment.

Key Takeaways

• BSMR‑200 (220 MWe) costs ₹5,960 crore.
• SMR‑55 (55 MWe) two units cost ₹7,000 crore.
• HTGCR (5 MWth) for hydrogen costs ₹320 crore.
• Lead units at Tarapur for BSMR‑200, SMR‑55; Vizag for HTGCR.
• BSMR‑200 construction estimated 60‑72 months after approvals.

Pulse Analysis

India’s push for small modular reactors reflects a strategic shift toward flexible, low‑carbon power generation. While traditional large‑scale reactors dominate the nuclear landscape, SMRs promise faster deployment, lower upfront capital, and the ability to serve remote or industrial sites. By integrating SMRs into its energy roadmap, India aims to meet rising electricity demand, reduce reliance on coal, and align with its climate commitments under the Paris Agreement. The government’s backing signals confidence in domestic nuclear expertise and a desire to capture emerging market opportunities.

The three SMR designs each target distinct applications. The 220 MWe BSMR‑200, co‑developed by BARC and NPCIL, is intended for grid‑scale supply and could replace aging thermal plants. The 55 MWe SMR‑55 offers a modular solution for regional grids or industrial clusters, with two units slated for construction. The 5 MWth high‑temperature gas‑cooled reactor is tailored for high‑efficiency hydrogen production, leveraging heat for water electrolysis—a critical step toward a domestic hydrogen economy. Cost estimates range from ₹320 crore for the HTGCR to ₹7,000 crore for the SMR‑55 pair, reflecting differing scales and technology maturity.

If timelines hold, the BSMR‑200 could be operational within six years, providing a template for future SMR rollouts. Successful execution would bolster India’s nuclear supply chain, attract foreign capital, and enhance its export credentials in SMR technology. Moreover, the hydrogen‑focused HTGCR aligns with global trends toward clean fuel production, potentially positioning India as a regional hub for green hydrogen. The initiative also underscores the strategic importance of sites like Tarapur and Vizag, which will become testbeds for next‑generation nuclear engineering, influencing policy and regulatory frameworks for years to come.
