India's 100GW Nuclear Dream Hinges on SMRs
India wants to increase its nuclear power capacity to 100GW by 2047 to meet growing electricity needs.
To do this, it plans to use small modular reactors (SMRs), which are smaller and more flexible than traditional nuclear reactors.
The government has passed a new law called the SHANTI Act to allow private companies to participate in the nuclear sector.
India is developing its own SMR designs, like the BSMR-200 and SMR-55, and aims to have five of them operational by 2033.
The country also plans to collaborate with other nations and leverage its existing manufacturing capabilities to make these SMRs cost-effective.
This move is part of India's effort to reduce greenhouse gas emissions and integrate more renewable energy into its power grid.
India aims to achieve 100GW nuclear power capacity by 2047 to meet increasing electricity demand.
The SHANTI Act, 2025, opens the nuclear sector to private participation and establishes regulatory bodies.
India is developing indigenous SMRs, including the BSMR-200 and SMR-55, with a budget allocation of ₹20,000 crore.
SMRs are expected to be cost-competitive and can be deployed in various settings, including remote areas and energy-intensive industries.
India plans to collaborate with global peers and leverage its domestic manufacturing ecosystem to support SMR development.
