What This Article Covers

1.India's first indigenous Fast Breeder Reactor (FBR) at Kalpakkam has attained criticality, a major step in the three-stage nuclear programme.

2.NPCIL plans to expand nuclear capacity from the current 22 GWe (target by 2031-32) to about 54 GWe by 2047, with 700 MWe PHWRs as the immediate workhorse.

3.The future energy basket will be a mix of indigenous PHWRs, Light Water Reactors (like Kudankulam), and FBRs, with NPCIL playing a 'motherly role' to foster private sector participation.

The Big Picture
Prelims · HighMains · Medium

India's nuclear energy strategy is pivoting with the criticality of its first indigenous Fast Breeder Reactor at Kalpakkam, marking a key milestone in the three-stage nuclear programme. While FBRs represent the long-term future for energy security using thorium, indigenously developed 700 MWe Pressurised Heavy Water Reactors will remain the mainstay for capacity expansion until the new technology matures, with a target to reach 54 GWe by 2047.

NPCIL Commences Fuel Loading at RAPP-8: 4th Indigenous 700 MWe PHWR in Fleet Mode

NPCIL has started initial fuel loading (IFL) at Unit 8 of Rajasthan Atomic Power Project (RAPP-8), a 700 MWe indigenous pressurised heavy water reactor (PHWR). This marks a major step in India's fleet-mode nuclear expansion, with commercial operation expected in 2026-27. For exams: understand PHWR technology, AERB's role, and the commissioning sequence (IFL → FAC → power generation).

Parliamentary Panel Recommends MDO Entry in Uranium Mining; India's 3-Stage Nuclear Plan to Thorium

The Parliamentary Committee on Atomic Energy has recommended allowing Mine Developer-cum-Operator (MDO) participation in uranium mining under DAE oversight to meet India's growing fuel demand for indigenous PHWRs. India currently imports uranium from Kazakhstan, Russia, Uzbekistan, and Canada, and aims to expand nuclear capacity from 8.7 GWe to 100 GWe by 2047. The three-stage nuclear program aims to transition from uranium to thorium for long-term energy self-sufficiency.
