Summary
The Prototype Fast Breeder Reactor at Kalpakkam achieved first criticality in April 2026, marking progress in the second stage.
Currently 24 reactors generate 8.78 gigawatts; nine more are under construction and ten new Pressurised Heavy Water Reactors have been approved.
The Nuclear Energy Mission and the Sustainable Harnessing and Advancement of Nuclear Energy (SHANTI) Act aim to boost domestic manufacturing, private‑sector participation, and reach 100 gigawatts of nuclear capacity by 2047.
The plan also includes Small Modular Reactors and a closed fuel cycle that recycles spent fuel and uses vitrification to turn high‑level waste into stable glass.
