Modi Hails Kalpakkam Reactor Criticality as Landmark Step in India’s Nuclear Program

New Delhi — Prime Minister Narendra Modi on Sunday described the achievement of criticality at India’s Prototype Fast Breeder Reactor in Kalpakkam as a “historic milestone” in the country’s nuclear energy journey.

Speaking during the 133rd episode of Mann Ki Baat, the Prime Minister highlighted the role of science and technology in national development, noting that India’s civil nuclear programme continues to contribute significantly to sectors such as industry, energy, healthcare, and agriculture.

Referring to the recent development in Tamil Nadu, he explained that achieving “criticality” marks the stage where a reactor sustains a controlled nuclear chain reaction, effectively signalling the beginning of its operational phase. He credited Indian scientists for advancing the programme and strengthening the country’s technological capabilities.

The 500 MWe sodium-cooled Prototype Fast Breeder Reactor is a key component of India’s three-stage nuclear power strategy. It is designed to produce more fissile material than it consumes using mixed oxide fuel, paving the way for the third stage, which focuses on utilising India’s vast thorium reserves for long-term energy security.

Emphasising self-reliance, Modi noted that the reactor has been developed entirely using indigenous technology. He added that such systems not only generate power but also create new fuel for future use, enhancing sustainability in the energy sector.

Recalling his visit to Kalpakkam in March 2024, when he witnessed the reactor’s core loading, the Prime Minister congratulated scientists and engineers involved in the project, stating that their efforts would contribute to improving lives and advancing the vision of a developed India.
