NPCIL completes largest-ever reactor foundation pour at Kaiga
The Nuclear Power Corporation of India Limited (NPCIL) has completed the largest continuous reactor foundation concrete pour for an Indian Pressurised Heavy Water Reactor (PHWR) at the Kaiga Units 5 and 6 nuclear power project. Around 7,250 cubic metres of concrete were poured for the reactor foundation despite challenging southwest monsoon conditions.
According to NPCIL, the continuous concrete pour was completed using a range of engineering measures designed to maintain construction quality during the monsoon. These included a specially designed 75-metre protective canopy, temperature-controlled concrete production, quality assurance protocols, and round-the-clock project coordination.
The milestone marks a key stage in the construction of the two 700 MW PHWR units being developed at the Kaiga nuclear power station.
Kaiga Units 5 and 6 are being built under the Make in India initiative using indigenous reactor technology. The project is part of India’s nuclear power expansion programme, which aims to increase low-carbon electricity generation through domestically developed reactor designs.
In June, NPCIL achieved another construction milestone at the project with the successful unloading of the first End Shield, a critical reactor core component.
