This reactor will include a core catcher and double containment as additional safety measures.
2.
The core catcher of the European Pressurized Reactor ( EPR ) has 170 m?expansion area and a mass of 500 t.
3.
Other new safety systems include aircraft crash protection and a core catcher to contain the molten reactor core in the event of a severe accident.
4.
A specific feature of the third generation reactor presented in the AES 92 variant is the provision of a " core catcher " for severe accident cases.
5.
Thus, in early 2011, the two reactors of the Chinese Tianwan Nuclear Power Plant are the only working nuclear reactors with this type of core catchers.
6.
A core catcher is made from a special concrete ceramic to prevent material from trickling through; it is also a cooling mechanism to cool down the core material.
7.
The AES-91, a project of Atomstroyexport based on the VVER-1000 design, will be the first type of nuclear plant that has a core catcher directly underneath the reactor.

:: : Poking around a bit more finds the relevant concept at core catcher, a portion of the plant engineered to catch and cool molten corium from a meltdown . & mdash; Lomn 19 : 15, 11 April 2012 ( UTC)
