India's civil nuclear programme.

Every operating reactor, every unit under construction, and the fuel-cycle, regulator, and policy architecture behind them.

Infrastructure

At a glance

  1. 01India operates 23 commercial reactors at 7 sites — 19 indigenous PHWRs and 2 Russian VVER-1000s — for 8,560 MWe gross / 7,730 MWe net.
  2. 0210 reactors are currently under construction adding 8,000 MWe of capacity, including the four KKNPP VVER-1000s, Kaiga 5/6, GHAVP 1/2 in Haryana, and BHAVINI's PFBR fast breeder at Kalpakkam.
  3. 03BHAVINI's 500 MWe Prototype Fast Breeder Reactor at Kalpakkam achieved first criticality on 6 April 2026, an official milestone associated with Stage II of India's three-stage nuclear-power programme.
  4. 04AERB licenses every reactor; the Civil Liability for Nuclear Damage Act 2010, India-US 123 Agreement (2008), 2008 NSG waiver, and 2014 IAEA Additional Protocol set the legal perimeter for civil nuclear cooperation.

Cumulative installed nuclear capacity

Reactors commissioned per decade

Operating capacity by site

Operating fleet by reactor type

Indian-design PHWRs dominate the fleet by unit count; the two Russian VVER-1000s carry an outsized share of the gross MWe.

Out of scope: strategic / weapons-side facilities

Strategic facilities (CIRUS legacy, Dhruva, FBTR research reactor, military reprocessing), reactor-grade plutonium inventory, and India's research-reactor estate (BARC Trombay) are deliberately excluded — this is a civil-programme page only.

Data provenance

Reporting dates
Operating fleet as of 1 Aug 2026; project status as of 15 May 2026
Coverage
23 operating reactors at 7 sites, 11 projects under construction or planned, 3 DAE fuel-cycle PSUs and 6 regulator/policy instruments
Limitations
Civil-only programme — strategic facilities, military reprocessing, and BARC's research reactors are out of scope. CoD dates for under-construction units are operator targets and have repeatedly slipped. MAPS-1 is excluded from the operating fleet count following IAEA's suspended-operation classification.
