:Mumbai, March 01, 2026
Nuclear Power Corporation of India Limited (NPCIL) today achieved a significant
milestone of the First Pour of Concrete (FPC) of Kaiga Units-5&6 after obtaining all
requisite statutory and regulatory clearances. Dr. Ajit Kumar Mohanty, Chairman,
AEC & Secretary DAE; Shri Bhuwan Chandra Pathak, CMD, NPCIL and senior officers
of NPCIL among other dignitaries were present on the occasion.
FPC marks a defining milestone in a Nuclear Power Project signifying start of
construction and its transition from pre-project phase to construction phase. The
gestation period of a project is reckoned from FPC. The first unit of Kaiga Units-5&6
project is expected to achieve criticality in about 60 months from FPC.
In a first, Kaiga-5&6 project is being implemented adopting an innovative strategy
involving just a few mega EPC packages (like Excavation, Nuclear Island, Turbine
Island and Nuclear Instrumentation) to enable faster project execution and reduced
interface issues.
Kaiga Units-5&6 are state-of-the-art, indigenous 700 MW PHWRs, which incorporate
advanced safety features and are among the safest in the world. Three such PHWRs
i.e. KAPS-3&4 and RAPP-7, are successfully operating in the states of Gujarat and
Rajasthan respectively. The components and equipment for the project are supplied
by domestic industry partners and works are being executed by Indian contractors,
aligning with the Atmanirbhar initiatives of the Government.
At present, the Kaiga site has four 220 MWe units in operation with a total installed
capacity of 880 MW. Upon completion of Units-5&6, the total installed capacity at
the site would reach to 2,280 MW.
This project is expected to create substantial employment and business
opportunities for the local people, stimulate economic development in the region &
beyond, and enhance infrastructure in the surrounding areas.
The expansion of Kaiga site reflects NPCIL’s commitment towards providing clean
power to meet the country’s Viksit Bharat and Net Zero goals, upholding the highest
standards of nuclear safety and environmental stewardship.***
