New Delhi, April 7, 2026:
Prime Minister Narendra Modi has hailed the successful attainment of criticality of India’s first indigenous Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, calling it a “defining step in India’s civil nuclear journey.”
Major Milestone in India’s Nuclear Programme
The PFBR, developed at Kalpakkam, marks a significant advancement in the second stage of India’s three-stage nuclear power programme.
The Prime Minister highlighted that this achievement strengthens India’s long-term vision of energy security and self-reliance.
“A proud moment for India. Congratulations to our scientists and engineers,” PM Modi said.
What Makes the Fast Breeder Reactor Unique?
The Prototype Fast Breeder Reactor is a highly advanced nuclear system with unique capabilities:
- Produces more fuel than it consumes
- Uses Uranium-Plutonium Mixed Oxide (MOX) fuel
- Converts Uranium-238 into additional fuel through nuclear transmutation
- Supports future use of Thorium-based fuel
This makes it a critical step toward utilizing India’s vast thorium reserves.
Step Towards Thorium-Based Energy Future
India has one of the largest thorium reserves in the world. The PFBR plays a key role in:
- Generating Uranium-233 from Thorium-232
- Enabling the third stage of India’s nuclear programme
- Reducing dependence on imported nuclear fuel
This aligns with India’s long-term sustainable and clean energy goals.
Developed Under Aatmanirbhar Bharat Vision
The reactor has been designed and constructed by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI), with contributions from over 200 Indian industries, including MSMEs.
This reflects India’s push toward self-reliance (Aatmanirbhar Bharat) in advanced nuclear technology.
India Joins Elite Nuclear Club
Once fully operational, India will become only the second country after Russia to run a commercial Fast Breeder Reactor.
This places India among the global leaders in advanced nuclear technology and innovation.
Advanced Safety Features
The PFBR is a third-generation nuclear reactor equipped with:
- Passive safety systems
- Automatic shutdown mechanisms
- Enhanced protection against emergencies
These features ensure high levels of operational safety and reliability.
The successful criticality of the PFBR at Kalpakkam is a landmark achievement for India’s nuclear energy ambitions. It not only strengthens the country’s energy independence but also positions India as a global leader in next-generation nuclear technology.
