how many nuclear power plant in india

India has 24 operational nuclear reactors spread across 7 nuclear power plants (also called stations) in 6 states, with a total installed capacity of approximately 8,780 MWe as of early 2026.

These plants are managed by the Nuclear Power Corporation of India Limited (NPCIL) and play a key role in the country's clean energy mix, contributing about 3% of total electricity while supporting ambitious expansion goals.

Current Status

India's nuclear sector has grown steadily, with 24 reactors in operation (excluding one under extended shutdown). This includes 20 Pressurized Heavy Water Reactors (PHWRs), 2 Boiling Water Reactors (BWRs), and 2 Pressurized Water Reactors (PWRs).

• Total capacity : 8,780 MW, though four reactors (760 MW) are undergoing renovation.

• Expansion underway : 8 more reactors (6,600 MW) under construction, plus 10 planned (7,000 MW).

• States hosting plants: Maharashtra, Rajasthan, Tamil Nadu, Uttar Pradesh, Gujarat, Karnataka.

Recent parliamentary updates confirm this setup, highlighting projects like Rawatbhata (Rajasthan) and Kudankulam (Tamil Nadu).

Plant Locations

Here's a breakdown of the 7 operational sites :

Plant Name| Location (State)| Reactors (Operational)| Key Notes 13
---|---|---|---
Tarapur Atomic Power Station| Maharashtra| 4 (2 BWR, 2 PHWR)| India's first, oldest plant
Rajasthan Atomic Power Station (Rawatbhata)| Rajasthan| 8 PHWR| Largest cluster; expansions ongoing
Madras (Kalpakkam) Atomic Power Station| Tamil Nadu| 4 PHWR + 2 PFBR| Includes fast breeder tech
Narora Atomic Power Station| Uttar Pradesh| 2 PHWR| Inland site on Ganges tributary
Kakrapar Atomic Power Station| Gujarat| 4 PHWR| Indigenous PHWR focus
Kaiga Generating Station| Karnataka| 4 PHWR| Highest capacity factor often
Kudankulam Nuclear Power Plant| Tamil Nadu| 2 PWR| Russia-assisted VVER design

This table reflects 2026 data ; capacities vary per unit (e.g., 220-700 MW).

Growth Story

India's nuclear journey started with Tarapur in 1969, evolving from imported tech to self-reliance via PHWRs. By 2025-26, capacity hit 8.8 GW amid global clean energy pushes—think net-zero targets by 2070.

"India operates 24 nuclear reactors with an installed capacity of 8780 MWe across seven locations."

Under construction: Gorakhpur (Haryana), Chutka (Madhya Pradesh)—aiming for 22 GW by 2031. Challenges like uranium supply and public concerns persist, but output hit record highs recently.

Future Outlook

With 8 reactors building and small modular reactors (SMRs) in R&D, India eyes massive scaling. This aligns with PM Modi's energy security vision post-2024 elections.

TL;DR : 7 plants, 24 reactors operational today—expanding fast for green power.
