India plans to develop and operationalise at least five indigenously designed Small Modular Reactors (SMRs) by 2033.
The Bhabha Atomic Research Centre (BARC) is designing three reactor types: 220-megawatt electric (MWe) Bharat SMR, 55 MWe SMR, and up to 5-megawatt thermal (MWth) High-Temperature Gas-Cooled Reactor (HTGR).
The Bharat SMR and SMR-55 use Pressurised Water Reactor (PWR) technology, which uses high-pressure water as both coolant and moderator.
The HTGR will be developed at Visakhapatnam to produce hydrogen using nuclear heat.
India aims to achieve 100 gigawatts (GW) of nuclear power capacity by 2047, with about 22 GW targeted by 2031–32.
