New Delhi, April 6 Prime Minister Narendra Modi on Monday hailed the country’s scientists for indigenously designing and building the Prototype Fast Breeder Reactor at Kalpakkam in Tamil Nadu.
The Prime Minister said that India has taken a defining step in its civil nuclear journey, advancing the second stage of its nuclear programme.
“The indigenously designed and built Prototype Fast Breeder Reactor at Kalpakkam has attained criticality,” he said.
The Prime Minister added that this advanced reactor, capable of producing more fuel than it consumes, reflects the depth of the country’s scientific capability and the strength of our engineering enterprise.
PM Modi said that it is a decisive step towards harnessing our vast thorium reserves in the third stage of the programme.
“A proud moment for India. Congratulations to our scientists and engineers,” the Prime Minister said.
In 2024, Prime Minister Modi witnessed the commencement of “core loading” at the 500 MWe PFBR unit in Kalpakkam, Tamil Nadu.
During the visit, he toured the reactor vault and the control room and received a briefing on the facility’s key features.
Once operational, India will become the second country, after Russia, to operate a commercial Fast Breeder Reactor.
Reflecting the Aatmanirbhar Bharat initiative, the PFBR was fully designed and constructed indigenously by BHAVINI, with significant contributions from over 200 Indian industries, including micro, small, and medium enterprises (MSMEs).
The reactor will initially use Uranium-Plutonium mixed oxide (MOX) fuel. The Uranium-238 “blanket” surrounding the fuel core undergoes nuclear transmutation to produce more fuel, hence the designation “breeder.”
The use of Thorium-232 as a blanket is also planned at this stage.
“
The FBR thus functions as a stepping stone for the third stage of India’s nuclear programme, facilitating the full utilisation of the country’s abundant thorium reserves.
India can also use thorium cycle-based processes to extract nuclear fuel.
This is of special significance to India's nuclear power generation strategy, as India has one of the world’s largest thorium reserves, which could provide power for as long as 60,000 years.
