Installation of the core catcher has been completed for Unit 5 at the Kudankulam nuclear power station under construction in Tamil Nadu, southern India, Russian state nuclear corporation Rosatom said.

The core catcher – also known as a core melt localisation device or core trap – is designed to catch the molten core material, or corium, of a nuclear reactor in the event of a nuclear meltdown and to prevent it from escaping the containment.

Rosatom said the 156-tonne component was delivered to Kudankulam-5 in January 2023.

In April, Russia also shipped the reactor pressure vessel and the full set of four steam generators for the new-build project.

Construction of Kudankulam-5, a Russia-designed VVER-1000 pressurised water reactor unit, began in June 2021.

There are three other reactor units of the same design under construction at the site – Kudankulam-3 and -4 since 2017 and Kudankulam-6 since 2021.

Kudankulam-1 and -2 began commercial operation in 2014 and 2017.
