The
Russian physicist who helped design the Russian core-catcher model during the Chernobyl crisis, Leonid Bolshov, has stressed that the experience of Chernobyl has encouraged Russia to create reactors with core-catcher safety devices in new nuclear plants.

A core catcher is made from a special thermally resistant concrete ceramic to prevent nuclear core material from melting through the core catcher; it also has a cooling mechanism to cool down the core material. The core catcher of the

based on the VVER-1000 design, was envisaged to be the first type of nuclear plant to have a core catcher directly underneath the reactor. Thus, in early 2011, the two reactors of the
