**Summary:**
As of August 6, 2025, India's installed nuclear power capacity is 8780 MW, comprising 24 reactors, excluding the long-term shutdown RAPS1 (100 MW). Four reactors are currently undergoing refurbishment and upgrade projects: Tarapur Atomic Power Station Units 1&2 (2 x 160 MW), Madras Atomic Power Station Unit 1 (1 x 220 MW), and Kaiga Atomic Power Station Unit 1 (1 x 220 MW). The remaining 20 reactors are operational.
Several projects are under construction, including RAPP8 (1 x 700 MW) in Rajasthan, KKNPP3&4 (2 x 1000 MW) and KKNPP5&6 (2 x 1000 MW) in Kudankulam, Tamil Nadu, PFBR (1 x 500 MW) in Kalpakkam, and GHAVP1&2 (2 x 700 MW) in Gorakhpur, Haryana. Pre-project activities are underway for Kaiga 5&6 (2 x 700 MW) in Karnataka, GHAVP 3&4 (2 x 700 MW) in Gorakhpur, Haryana, Chutka 1&2 (2 x 700 MW) in Madhya Pradesh, and Mahi Banswara 1&2 and 3&4 (4 x 700 MW) in both Rajasthan and Madhya Pradesh.
The Nuclear Power Corporation of India Limited (NPCIL) implements these projects, and BHAVINI is assigned to Anushakti Vidyut Nigam Limited (ASHVINI). Upon completion of these projects, the installed nuclear power capacity is projected to reach 22,380 MW by 2032.
Specifically, at Tarapur, Maharashtra, Units 3&4 (2 x 540 MW) are currently operating, while Units 1&2 (2 x 160 MW) are being refurbished and upgraded. These units will be restarted upon regulatory clearance. The Mahi Banswara Nuclear Power Project (2800 MW total) has acquired land and obtained statutory environmental clearance from the MoEFCC and siting consent from AERB; pre-project activities are in progress.
