India has set target of 200 GW nuclear energy, setting up five new reactors: PM
India's nuclear power capacity expansion targets and plans for five new nuclear reactors were announced during the 80th Independence Day address from the Red Fort
The announcement referenced the Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, having attained criticality in 2026
Nuclear energy was described as a key pillar of India's energy security strategy, alongside other energy initiatives such as expanded piped gas and solar household connections mentioned in the same address
The PFBR milestone was linked to India's broader push toward self-reliance ("Atmanirbhar Bharat") in the nuclear power sector
India's Three-Stage Nuclear Power Programme
Conceived by physicist Homi J. Bhabha in the 1950s, this is the strategic roadmap by which India aims to use its modest uranium reserves and vast thorium reserves (found largely in monazite sands along the southern coast) to achieve long-term energy security.
Key Details
- Stage 1: Pressurised Heavy Water Reactors (PHWRs) use natural uranium as fuel and generate plutonium-239 as a by-product
- Stage 2: Fast Breeder Reactors (FBRs) use this plutonium as fuel and "breed" more fissile material than they consume, while also converting thorium-232 into fissile uranium-233
- Stage 3: Thorium-based reactors, using the uranium-233 bred in Stage 2, will eventually exploit India's large thorium reserves at scale
- The Kalpakkam PFBR (500 MWe, built by BHAVINI, using uranium-plutonium mixed oxide/MOX fuel) attained first criticality on 6 April 2026, marking India's formal entry into Stage 2 of the programme; with this, India becomes only the second country after Russia to operate a commercial-scale fast breeder reactor
The Independence Day reference to the PFBR criticality and new reactors frames the announcement within this decades-old Bhabha roadmap — the PFBR is the technological bridge between Stage 1 (existing PHWR fleet) and Stage 3 (thorium utilisation).
SHANTI Act, 2025 — Reforming India's Nuclear Liability and Private Participation Framework
The Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act, 2025 restructures India's nuclear governance to enable private and foreign investment in nuclear power generation for the first time.
Key Details
- It repeals and replaces both the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage (CLND) Act, 2010, consolidating nuclear law under a single statute
- It allows private and foreign participation in building/operating nuclear plants while retaining state control over strategic (weapons-related) activities; Foreign Direct Investment (FDI) in nuclear power projects is capped at 49%
- It introduces tiered operator liability linked to plant capacity (from ₹100 crore for plants under 150 MW to ₹3,000 crore for plants over 3.6 GW), with overall liability per incident capped around 300 million Special Drawing Rights (SDR)
- It removes the automatic statutory "right of recourse" against equipment suppliers that existed under the 2010 CLND Act (Section 17b), leaving supplier liability to be determined contractually — a change long sought by foreign reactor vendors
The SHANTI Act is the enabling legal framework behind the expansion target and the "five new reactors" plan — without its liability reforms, foreign and private capital needed to scale up reactor construction was not forthcoming, which is why the Act preceded this announcement.
India's Nuclear Capacity Targets — 100 GW by 2047
India's officially stated nuclear capacity target, reiterated in government and parliamentary sources under the SHANTI Act framework, is 100 GW of installed nuclear capacity by 2047 (the centenary of independence) — roughly a twelvefold increase from the current installed base. [Note: some contemporaneous media reports of this Independence Day speech cite a "200 GW" figure; the consistently corroborated official target across government and multiple independent reports is 100 GW by 2047, and that figure has been used here.]
Key Details
- India's current installed nuclear capacity is approximately 8.8 GW (about 3% of total electricity generation), spread across operational PHWRs and a small number of other reactor types
- Existing capacity is projected to reach about 22 GW by 2031-32 as under-construction projects (including additional PHWRs) are commissioned
- The Nuclear Power Corporation of India Limited (NPCIL) plans roughly 32 GW of further indigenous PHWR/Light Water Reactor capacity beyond 2032, taking state-led capacity to about 54 GW by 2047, with the remainder expected to come from private/foreign participation enabled by the SHANTI Act
- The Union government has separately approved a "100 GW Nuclear Energy Mission" push, including support for Small Modular Reactors (SMRs) and Bharat Small Modular Reactors (BSMRs)
The "five new reactors" and capacity-expansion announcement should be read against this 100 GW-by-2047 roadmap — the PFBR's criticality is an early, symbolic milestone within a much longer capacity build-out that depends heavily on the SHANTI Act's private-investment provisions succeeding.
- PFBR (Kalpakkam): 500 MWe, uranium-plutonium MOX-fuelled fast breeder reactor, attained first criticality on 6 April 2026; commercial operation expected around September 2026
- India is only the second country (after Russia) to operate a commercial-scale fast breeder reactor
- India's current installed nuclear capacity: approximately 8.8 GW (~3% of total electricity generation)
- Officially reiterated target: 100 GW nuclear capacity by 2047 (~12x increase); projected ~22 GW by 2031-32
- SHANTI Act, 2025 repeals the Atomic Energy Act, 1962 and the CLND Act, 2010; caps FDI in nuclear power at 49%
- Tiered operator liability under SHANTI Act: ₹100 crore (plants under 150 MW) to ₹3,000 crore (plants over 3.6 GW); overall per-incident cap around 300 million SDR (~USD 430 million)
