Graphite in nuclear plants
WebGraphite materials, such as high-density isotropic graphite and carbon fiber/carbon composite, are also used in nuclear-fusion reactors as interior liners, movable limiters … WebNuclear fission takes place in a nuclear reactor, which is an enclosed vessel containing a set of nuclear fuel rods that are typically made of uranium or plutonium. The fuel rods are surrounded by a moderator, typically water or graphite, which helps slow down the neutron particles and causes the uranium or plutonium atoms to split.
