Report overview

The India Nuclear Reactors Database catalogues every operational, under-construction, and planned nuclear power reactor across India, built around a fixed reference year of 2026. The dataset is organized at the plant and unit level, capturing reactor technology, gross and net capacity, commissioning timelines, and operating utility for each site from Tarapur and Rawatbhata to Kudankulam and the upcoming Jaitapur complex.

Database Coverage

Unit-Level Reactor Records covering every commissioned, under-construction, and announced reactor.
State & Regional Mapping of nuclear generation capacity across India.
Technology Breakdown by PHWR, BWR, VVER/PWR, and upcoming SMR and Bharat Small Reactor designs.
Operator & Ownership Profiles for NPCIL and joint-venture nuclear power projects.
Expansion Pipeline Tracking of new units, site approvals, and capacity addition targets to 2032.

Strategic Indicator	Current Position	Business Implication
Leading State by Capacity	Tamil Nadu	Anchors the Kalpakkam and Kudankulam nuclear complexes.
Programme Stage	Stage 2 (Fast Breeder)	PFBR criticality in 2026 marks entry into the second stage.
Capacity Target (2031-32)	~22,480 MW	Nearly triples current installed capacity within the decade.
Long-Term Target (2047)	100 GW	Anchored by the Nuclear Energy Mission and SMR development.

Executive summary

Industry Landscape

India’s nuclear power programme is entering an accelerated expansion phase as the country targets a multi-fold increase in installed nuclear capacity to support its energy security and decarbonization goals. As of 2026, India operates a fleet of reactors spread across sites in Rajasthan, Tamil Nadu, Gujarat, Karnataka, Uttar Pradesh, and Maharashtra, with additional capacity under construction at Kakrapar, Rajasthan, and Kudankulam.

Key Growth Drivers

Nuclear Energy Mission funding: The Union Budget’s ₹20,000 crore allocation for indigenous Small Modular Reactors is accelerating India’s nuclear reactor pipeline beyond the traditional PHWR fleet.
SHANTI Act reforms: Recent legal modernization allows limited private-sector participation in nuclear power generation for the first time, widening the pool of capital and operators.
Three-stage programme progress: The Prototype Fast Breeder Reactor’s 2026 criticality milestone unlocks the second stage of India’s long-term thorium utilization strategy.
Energy security and decarbonization goals: Nuclear power’s low-carbon, baseload characteristics make it a central pillar of India’s push toward 100 GW of installed capacity by 2047.

Key Structural Trends

The database tracks reactor-level detail including gross capacity in MWe, reactor technology, first-criticality and commercial-operation dates, and the responsible operating entity, alongside newly announced sites tied to the government’s private-sector participation push in nuclear energy.

Methodology & Data Sources

Research Methodology

The India Nuclear Reactors Database is developed using a structured, multi-source research process designed to ensure accuracy and consistency across every tracked record.

Step 1: Scope Definition & Universe Mapping

The research team defines the full universe of nuclear reactors to be tracked within scope, drawing on regulatory filings, industry association membership lists, company disclosures, and prior desk research to establish an initial master list.

Step 2: Data Collection & Verification

Each record is populated using primary sources including company announcements, regulatory and permitting filings, government databases, and, where available, direct outreach to operators and developers, cross-checked against secondary sources such as industry reports and trade press coverage.

Step 3: Classification & Standardization

Records are standardized into a consistent schema covering location, capacity or scale, ownership, operational status, and timeline detail, allowing like-for-like comparison across all regions of India.

Step 4: Quality Review & Update Cycle

The database is reviewed on a periodic basis to reflect newly announced projects, status changes, and ownership updates, with the 2026 reference year reflecting the most recent verified data snapshot at time of publication.

FAQs

01 What does the India Nuclear Reactors Database cover?

It provides unit-level records for every operational, under-construction, and planned nuclear reactor in India, including reactor technology, gross and net capacity, commissioning status, and operator, benchmarked to a 2026 reference year.

02 Which states lead India nuclear capacity?

Tamil Nadu leads on installed capacity through the Kalpakkam and Kudankulam complexes, followed by Gujarat, Maharashtra, and Rajasthan, with the database providing full state-level and site-level rollups.

03 Does the database track Small Modular Reactors and the Nuclear Energy Mission?

Yes, coverage includes the government SMR pipeline, Bharat Small Reactor designs, and Nuclear Energy Mission-linked funding commitments alongside the traditional PHWR fleet.

04 Who are the primary operators covered?

The database covers NPCIL-operated stations, BHAVINI fast breeder programme, and newly structured joint ventures formed under the SHANTI Act reforms.

05 How often is the database refreshed?

The dataset reflects the 2026 reference year and is updated as new units achieve criticality, as fresh site approvals are announced, or as capacity targets toward 2047 are revised.
