G21C7/103 - CPC Classification

Classification description:

Control of nuclear reaction by application of neutron-absorbing material, i.e. material with absorption cross-section very much in excess of reflection cross-section by displacement of solid control elements, e.g. control rods; Construction of control elements Control assemblies containing one or more absorbants as well as other elements, e.g. fuel or moderator elements
