0 a soft, dark grey form of carbon, used in the middle of pencils, as a lubricant in machines, and in some nuclear reactors --

There is a helium gas manifold to cool the graphite.
They are stooped mainly in graphite blanket and heats up the graphite.
Neutrons carry their energy into the graphite blanket and are stopped.
Empirical three-body potentials are also used to simulate materials such as graphite.
This graphite blanket has many holes of small diameter and helium gas as a coolant passes through them.
This consists of a graphite core surrounded by a layer of paste particles that becomes firm during baking.
Metasedimentary samples from the southeastern portion are represented by graphite schist and metapelite.
The graphite moderates the neutrons below activation energy levels.
