India Develops Small Nuclear Reactors for Ships and Industry: BARC’s SMR Breakthrough Ushers in Maritime and Industrial Energy Revolution
In a groundbreaking advancement for India’s energy security and clean technology landscape, the Bhabha Atomic Research Centre (BARC) has successfully developed and tested India’s first indigenous Small Modular Reactor (SMR) prototype, tailored for propulsion in naval ships and powering industrial applications. Unveiled on October 15, 2025, at the Trombay facility near Mumbai, the 50 MW thermal SMR—dubbed “Aakash”—promises compact, scalable nuclear power that could equip aircraft carriers, submarines, and heavy industries with emission-free energy. This milestone, achieved under the Atmanirbhar Bharat initiative, positions India among a select group of nations like the U.S. and Russia with advanced SMR capabilities, potentially reducing fossil fuel dependency by 15% in maritime and manufacturing sectors by 2035.
As the prototype undergoes rigorous safety trials, the government eyes commercial deployment by 2028, with partnerships from Larsen & Toubro (L&T) for ship integration. This development not only bolsters the Indian Navy’s blue-water ambitions but also aligns with global net-zero goals, offering a blueprint for sustainable industrial growth. This comprehensive article explores the SMR’s technical details, its strategic importance, historical evolution, economic impacts, future deployment, and more, providing a full perspective on India’s nuclear innovation surge.
Why India’s SMR Development for Ships and Industry Matters
The advent of indigenous SMRs addresses critical challenges in India’s energy mix, where maritime transport accounts for 95% of trade volume yet relies on polluting diesel, contributing 3% to national emissions. Aakash’s modular design—factory-built for quick assembly—enables flexible deployment on vessels like the INS Vikrant successor or in industrial clusters like Gujarat’s chemical hubs, slashing fuel costs by 40% and operational downtime by 50%. This matters for national security, enhancing the Navy’s endurance in the Indo-Pacific amid China’s expanding fleet, while economically, it could save Rs 20,000 crore annually in imported fuels. For the $100 billion Indian nuclear sector, growing at 10% CAGR, SMRs democratize atomic energy, extending it beyond large plants to SMEs and remote industries. Globally, it elevates India’s profile in the $50 billion SMR market by 2030, fostering exports and collaborations under the IAEA framework.
Key Features of BARC’s ‘Aakash’ SMR
| Feature | Description | Benefits |

India’s Nuclear Journey to SMRs
India’s atomic program began with Homi Bhabha’s 1948 vision, achieving the 1974 peaceful test despite NSG sanctions. The 2008 Indo-US deal unlocked civilian tech, leading to 23 reactors today (7.5 GW capacity). SMR research started in 2010 under the NPCIL, with Aakash evolving from the 2020 AHWR prototype. This 2025 milestone builds on INS Arihant’s 2016 nuclear submarine, aiming for 22 GW capacity by 2031.
