The Department of Atomic Energy has adopted a three-stage nuclear power programme based on a closed nuclear fuel cycle to optimally utilise limited uranium and large thorium reserves for long-term energy security. This programme aims to multiply domestically available fissile resources. The first stage involves using natural Uranium in Pressurised Heavy Water Reactors (PHWRs), followed by using Plutonium from spent fuel in Fast Breeder Reactors. The third stage will involve using Thorium to produce Uranium-233 in Fast Breeder Reactors. The first stage of indigenous PHWRs is in industrial domain, and a Prototype Fast Breeder Reactor (PFBR) is being commissioned by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI) in Kalpakkam, Tamil Nadu. Nuclear power is a clean, 24x7 baseload electricity source with lifecycle emissions comparable to renewables, contributing to India's clean energy transition towards Net Zero by 2070.

NUCLEAR ENERGY
प्रव तथ: 17 DEC 2025 2:01PM by PIB Delhi
Nuclear Energy has a huge potential to ensure long term energy security. With a view to optimally utilise
limited uranium reserves and large thorium reserves in the country, the Department of Atomic Energy has
adopted a three-stage nuclear power programme, based on a closed nuclear fuel cycle, for generation of
nuclear power and for achieving long term energy security. The three-stage nuclear power programme,
which is to be implemented sequentially, aims to multiply the domestically available fissile resources
through the use of natural Uranium in Pressurised Heavy Water Reactors (first stage), followed by use of
Plutonium obtained from the spent fuel of Pressurised Heavy Water Reactors in Fast Breeder Reactors, in
the second stage. Large scale use of Thorium will subsequently follow making use of Uranium- 233 that
will be bred in Fast Breeder Reactors, when adequate nuclear installed capacity in the country has been
built. Accordingly, the utilisation of Thorium as a practically inexhaustible energy source has been
contemplated during the third stage of the Indian nuclear programme, which can be reached in future. The
first stage of nuclear power programme comprising indigenous Pressurised Heavy Water Reactors
(PHWRs) is in industrial domain. A Prototype Fast Breeder Reactor (PFBR) under the second stage is
being commissioned by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI) at Kalpakkam, Tamil
Nadu.
Nuclear power is a clean, base load source of electricity available 24X7. The lifecycle emissions of
nuclear power are comparable to those of renewables like hydro and wind. Thus, nuclear energy will
contribute significantly in India’s clean energy transition towards Net Zero by 2070.
