India’s Indigenous Fast Breeder Reactor Achieves Major Milestone
India has achieved a significant milestone in nuclear energy as its 500 MW Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, reached its second stage and achieved "criticality" on Monday night.
Achieving criticality means the reactor has initiated a self-sustaining nuclear chain reaction and has started generating energy.
The reactor is now just one step away from becoming fully operational. More than 80% of the technology and equipment used in this project are indigenous.
Currently, only Russia has operational fast breeder reactor technology. Once fully completed, India will become the second country in the world to achieve this feat.
The reactor has been designed by the Indira Gandhi Centre for Atomic Research (IGCAR). After this achievement, Prime Minister Narendra Modi stated that India has reached a major milestone in its nuclear journey and the country’s nuclear program will now progress at a faster pace.
The project was initiated in 2003 and involved the collaboration of more than 200 Indian companies.
A fast breeder reactor is a special type of nuclear reactor that uses mixed oxide (MOX) fuel, a combination of uranium and plutonium.
Its key advantage is that it can produce more fuel than it consumes, making it highly efficient. This technology also opens pathways for thorium-based energy production, which is crucial for India.
Why This Matters
Rising Power Demand: Unlike solar and wind energy, which depend on weather, nuclear power provides continuous electricity. A single reactor can power millions of homes.
Thorium Reserves: India has limited uranium but one of the world’s largest thorium reserves. Fast breeder reactors can convert thorium into Uranium-233 for energy use.
Environment: India aims to achieve net-zero carbon emissions by 2070. Nuclear energy is considered cleaner compared to coal.
Land Efficiency: Nuclear plants generate large amounts of electricity using much less land compared to solar power plants.
Global Scenario
China: Rapidly expanding nuclear power capacity and aiming for global leadership.
United States: Has the largest number of operational reactors, though many are aging.
India: Currently generates around 3% of its electricity from nuclear energy, with a target to increase it 12 times by 2047.
Russia: Leads in advanced nuclear technology and supports countries like India, Turkey, and Bangladesh in nuclear development.
