**Summary of Expansion of Nuclear Power Generation Capacity**
**Overview and Current Status**
As of March 19, 2026, the Department of Atomic Energy reports that India’s total installed nuclear power capacity stands at 8,780 MW. This capacity is generated by 24 nuclear power plants, a figure that excludes the 100 MW RAPS-1 unit.
**Generation Performance**
Nuclear power generation has shown a consistent upward trend over the last three fiscal years:
* **2022-23:** 45,855 Million Units (MUs)
* **2023-24:** 47,971 MUs
* **2024-25:** 56,681 MUs
**Expansion Projects under Implementation**
There are currently 18 nuclear power reactors under implementation with a combined capacity of 13,600 MW. This includes 10 reactors currently under construction or commissioning and 8 reactors in the pre-project activity phase.
**Projects Under Construction/Commissioning:**
* **Rajasthan (RAPP-8):** 700 MW
* **Kudankulam, Tamil Nadu (KKNPP-3&4):** 2,000 MW (2 x 1000 MW)
* **Kudankulam, Tamil Nadu (KKNPP-5&6):** 2,000 MW (2 x 1000 MW)
* **Gorakhpur, Haryana (GHAVP-1&2):** 1,400 MW (2 x 700 MW)
* **Kaiga, Karnataka (Kaiga-5&6):** 1,400 MW (2 x 700 MW)
* **PFBR, Kalpakkam:** 500 MW (1 x 500 MW)
**Projects Under Pre-project Activities:**
* **Gorakhpur, Haryana (GHAVP-3&4):** 1,400 MW (2 x 700 MW)
* **Chutka, Madhya Pradesh (Chutka-1&2):** 1,400 MW (2 x 700 MW)
* **Mahi Banswara, Rajasthan (Mahi Banswara-1&2):** 1,400 MW (2 x 700 MW)
* **Mahi Banswara, Rajasthan (Mahi Banswara-3&4):** 1,400 MW (2 x 700 MW)
**Key Institutional Developments**
BHAVINI is currently commissioning a 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu. Furthermore, the government has approved pre-project activities for the FBR 1&2 project (a 2 x 500 MWe twin unit) at the same location. Formal financial sanction for FBR 1&2 will be sought once the PFBR attains its first criticality.
