a) Nuclear grade graphite is any of the grades of graphite, usually electro-graphite, specifically manufactured for use as a moderator or reflector within nuclear reactors. Graphite is an important material for the construction of both historical and modern Nuclear reactors as it is one of the purest materials manufactured at industrial scale and it retains its properties (including strength) at high temperatures.
- Graphite Powder (Nuclear Grade) Typical Chemical Properties Available:
Care must be taken that reactor-grade graphite is free of neutron absorbing materials such as boron, widely used as the seed electrode in commercial graphite deposition systems-- this caused the failure of the Germans' World War II graphite-based nuclear reactors.

a) Special grades of synthetic graphite also find use as a matrix and neutron moderator within nuclear reactors. Its low neutron cross-section also recommends it for use in proposed fusion reactors. Care must be taken that reactor-grade graphite is free of neutron absorbing materials such as boron, widely used as the seed electrode in commercial graphite deposition systems—this caused the failure of the Germans' World War II graphite-based nuclear reactors. Since they could not isolate the difficulty they were forced to use far more expensive heavy water moderators. Graphite used for nuclear reactors is often referred to as nuclear graphite.
b) A new application for nuclear grade graphite is in Very High Temperature Reactors (VHTR) and the Next Generation Nuclear Plant (NGNP).
