India’s Third 700 MW Nuclear Reactor Begins Operations
India has successfully commissioned its third indigenous 700 MW pressurized heavy water reactor (PHWR), further strengthening its nuclear energy program. The Rajasthan Atomic Power Project Unit 7 (RAPP-7), located in Rawatbhata, Rajasthan, was synchronized with the Northern Grid on March 17, 2025. This milestone was achieved after securing all necessary approvals from the Atomic Energy Regulatory Board (AERB).
Boost to India’s Nuclear Energy Capacity
The commissioning of RAPP-7 marks another step toward India’s ambitious nuclear energy expansion. This reactor is part of a series of 16 planned 700 MW PHWRs being developed across the country. These reactors incorporate advanced safety features, making them among the safest nuclear power units globally.
With the successful operation of Kakrapar Atomic Power Station (KAPS) Units 3 and 4 in Gujarat, RAPP-7 further demonstrates the efficiency and reliability of India’s indigenous nuclear technology. This achievement highlights the expertise of the Nuclear Power Corporation of India Ltd (NPCIL) and the growing self-reliance of Indian industries in nuclear energy development.
Current and Future Nuclear Expansion Plans
With RAPP-7 now operational, India’s total nuclear power generation capacity has risen to 8,880 MW, spread across 25 functional reactors. This development aligns with the country’s long-term strategy to enhance clean energy production and reduce dependency on fossil fuels.
Further expansion is on the horizon, with RAPP-8, another 700 MW nuclear reactor, expected to be commissioned by the end of 2025. Once operational, this addition will increase India’s total nuclear power capacity to 9,580 MW, marking the largest annual increase in nuclear energy output in the nation’s history.
A Step Towards Energy Security
The commissioning of RAPP-7 signifies India’s commitment to energy security and sustainable development. By focusing on nuclear energy, the country aims to reduce carbon emissions, meet growing electricity demands, and bolster its position as a leader in advanced nuclear technology.
This latest milestone highlights India’s capability to develop and operate large-scale nuclear reactors, ensuring a stable and eco-friendly energy future for the nation.
