This reactor will include a core catcher and double containment as additional safety measures.

New core catchers were collected in Devonport and worked well for the rest of the cruise.

Also some of the core catchers proved to have substandard spring steel and did not close fully, thus allowing any sediments penetrated to escape.

Examples of reactor types with core catchers, besides the EPR, are:

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.

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.

Benthic foraminifers are present in core catchers throughout the cored interval except in the upper radiolarian clays and the late Eocene interval.

Thus, in early 2011, the two reactors of the Chinese Tianwan Nuclear Power Plant are the only working nuclear reactors with core catchers.

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.

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 as standard equipment.

The third-generation European Pressurized Reactor (EPR), conceived following the 1986 Chernobyl disaster, has a double containment wall and a "core catcher" to contain core meltdown.

A core catcher is a device provided to catch the molten core material (Corium) of a nuclear reactor in case of a nuclear meltdown and prevent it from escaping the containment building.

Although no cores were split for description aboard ship, brief descriptions were made of the core catcher material, and a few cores were logged for magnetic susceptibility through the plastic liners.

Some reactor building designs, for example, the EPR, incorporate dedicated corium spread areas (Core Catchers), where the melt can deposit without coming in contact with water and without excessive reaction with concrete.

Even if the worst were to occur, the EPR comes with a "core catcher" below the reactor containment vessel that is designed to prevent a melting reactor from burrowing China Syndrome-style into the ground.

Microscopes, PCs, buckets for rock samples, depressor weights for dredges, 75mm UPVC downpipe for core liners (comes in 6m lengths), core catchers (CSIRO can supply sample).

Mr. Shmatko said his company's plant in Tianwan, China, is the first in the world to use a "core catcher," a meltdown-control technology designed to trap the molten slug of uranium in a meltdown and prevent it from burrowing into the earth.

If core overheating and meltdown became unavoidable, these reactors have core catchers that will trap the molten fuel and stop the nuclear reaction (although Lungmen, as other ABWR does not have a core catcher but rely on passive cooling of the corium).

The tool consists of a handle, an auger bit and a small, half circular metal tray ( the core extractor) that fits into the auger bit; the last is usually manufactured from carbide steel.
