There are 22 nuclear reactors operational in seven nuclear power plants in India under the Department of Atomic Energy (DAE). These power plants largely contribute to the supply of electricity to the national grids. Let's learn about one such major nuclear power plant in India- the Kaiga Atomic Power Station.

What is the Kaiga Atomic Power Station?

The Kaiga Atomic Power Station is India's third major nuclear power plant. It is situated in Kaiga, Uttara Kannada district of Karnataka state. The plant is operated by the Nuclear Power Corporation of India Limited (NPCIL).

The first two Kaiga Atomic Power Station units were constructed under the Russian technology transfer. The reactor pressure vessel for Unit 1 was supplied by the Chelyabinsk Tube-Rolling Plant (Russia). BHEL manufactured the remaining engineering components for both units as part of their "Pressure parts" division.

Significance of Kaiga Atomic Power Station

The Kaiga Atomic Power Station is the first large-scale nuclear plant built in India. It is a two-unit pressurized heavy water reactor (PHWR) power station located in Kaiga, Kaveri River basin, near Karwar in Karnataka.

It was built by the Nuclear Power Corporation of India Limited (NPCIL), a Public Sector Undertaking under the Department of Atomic Energy (DAE) of the Government of India.

Safety Measures at Kaiga Atomic Station

Safety measures at the Kaiga Atomic Power Station include an emergency core cooling system and a core catcher. The emergency core cooling system (ECCS) is designed to cool the nuclear reactor in case of a power failure that might lead to overheating. The core catcher is a device that, in the event of an accident, would catch any fuel and other materials that would melt and drop down into the containment building.

There is also a backup system for cooling down the reactor if the ECCS does not work properly. This backup system uses borated water, which is stored in tanks around the plant and can be pumped into the reactor as needed.

The Kaiga Atomic Power Station is highly significant to the Indian nuclear program. This is one of the four major plants in the country. The other three are the Narora Atomic Power Station in Uttar Pradesh, Rawatbhata Atomic Power Station in Rajasthan, and two units at the Tarapur Atomic Power Station in Maharashtra. In recent years, it has been working to improve its safety measures in recent years, with an emphasis on letting the community know what steps are being taken to ensure their safety. Mock drills and exercises are done at regular intervals to train employees to handle any kind of emergency situation, including radioactive leakages and fires, etc.
