The case of the core melt localization device, or also known as “Molten Core Catcher” has been installed under the reactor pit of Unit 3 of the Kudankulam Nuclear Power Plant in Tamil Nadu of India. The case of the device weighs 147.5 tons, Rosatom state atomic energy corporation of Russia official said.
According to Rosatom official core melt localization device is a unique development of Russian nuclear experts and one of the most important element of NPP’s passive safety system. The core catcher was first installed at China’s Tianwan Nuclear Power Plant of Russian design.
Core catcher for Kudankulam NPP has been adapted for the site conditions and safety requirements. It has improved seismic resistance, hydro-dynamic and shock strength, as well as equipped with flood protection features.
A core melt localization device (CMLD), or a “Core Catcher,” is installed at the bottom of the station’s protective shell. It is designed to localize and cool the molten core material in case of a severe hypothetical accident that could lead to damage to the core. It excludes radioactive emission in the environment.
Rosatom state atomic energy corporation of Russia is the technical consultant and main equipment supplier for the Kudankulam Nuclear Power Plant.
