Preferred Label : nuclear graphite;
IUPAC definition : A polygranular graphite material for use in nuclear reactor cores consisting of graphitic
carbon of very high chemical purity. High purity is needed to avoid absorption of
low-energy neutrons and the production of undesirable radioactive species.;
Scope note : apart from the absence of neutron-absorbing impurities, modern reactor graphites are
also characterized by a high degree of graphitization and no preferred bulk orientation.
such properties increase the dimensional stability of the nuclear graphite at high
temperatures and in a high flux of neutrons. the term nuclear graphite is often, but
incorrectly, used for any graphite material in a nuclear reactor, even if it serves
only for structural purposes.;
