Installation of core catcher at unit 2 of Rooppur NPP begins

Atomstroyexport, Engineering Division of ROSATOM and the General Contractor Rooppur Nuclear Power Plant has started installation of Core Melt Localization Device (Core Catcher), one of the main elements of the passive safety system at Unit-2 of the project.

Installation works began on April 25, 2019, one month ahead of the schedule, said a press release.

“This is one of the main elements of a passive safety system and the first large-sized equipment being installed in Unit 2 building. Due to coordinated efforts of our engineers it has become possible to begin the installation works earlier. It is worthy to mention here that construction of both units of Rooppur NPP is progressing as per schedule,” said Sergey Lastochkin, Vice-President and Director of Rooppur NPP Project.

Installation of Core Catcher at Unit-1 began earlier on August 18, 2018.

Core catcher is a unique device, designed by Russian specialists. The device with cone-shaped body is installed at the bottom of the reactor core barrel and filled with a special material.

If necessity arises, the Core Catcher shall collect the core melt materials and ensure their uniform distribution in the core catcher body.

Operations of the Core Catcher like other passive safety systems do not depend on any person or his skill or circumstances. It follows only the fundamental natural law.

Core Catcher for Rooppur NPP is designed considering the site condition and safety requirements. For having improved hydro-dynamic and shock strength properties, it is more seismic resistant. It is also equipped with flood protection features and possesses simplified installation and assembly technology.

Rooppur NPP is being constructed with the technical and financial assistance from Russia. It will have two units each of 1200MW capacity. World’s latest 3+ Generation VVER 1200 reactors have been chosen for the plant, which completely fulfill the safety requirements set by IAEA.
