In a transformative move for its energy landscape, India has set its sights on a staggering 100 GW nuclear power capacity by 2047. This visionary target, tied to the 100th year of independence, seeks to fortify national energy security and diminish fossil fuel imports.
The country’s nuclear fleet today comprises 24 operational reactors totaling 8,780 MWe, with eight additional units at 6,028 MWe in various stages of construction. Experts forecast a jump to 22 GW by early 2030s, fueling the acceleration toward the century-long ambition.
The roadmap features a balanced approach: scaling up massive reactors like the indigenous 700 MWe PHWRs alongside imported behemoths on new sites. Complementing this are innovative SMRs, including the 200 MWe BSMR and compact 55 MWe SMR-55, ideal for remote or modular deployment.
Highlighting progress, the Kalpakkam PFBR marked a historic ‘first criticality’ on April 6, 2026. This 500 MWe reactor’s successful fission startup validates India’s three-stage nuclear cycle, designed for uranium efficiency and thorium dominance.
Stage I: Natural uranium fuels plutonium production in PHWRs. Stage II: Fast breeders multiply fuel using plutonium. Stage III: Thorium converts to uranium-233 for endless supply.
Powered by MOX fuel and sodium cooling, the PFBR not only generates 500 MW but breeds excess fuel, bridging to thorium era. Sufficient for half a million homes, it signals nuclear’s ascent in meeting India’s soaring electricity demands sustainably.
This initiative aligns with net-zero aspirations, promising economic growth, job creation in high-tech sectors, and a cleaner tomorrow.
