Nuclear Block Graphite-10 (NBG-10) is a medium-grain, near-isotropic graphite manufactured by SGL Carbon Company at their plant in Chedde, France. The filler coke is coal tar pitch derived (maximum size {approx} 1.6 mm). The graphite is formed by extrusion and doubly impregnated. The formulation and manufacturing process are based on that of the graphite fuel sleeves used for Advanced Gas Cooled Reactor fuel stringers in the United Kingdom. NBG-10 graphite was developed as a candidate core structural material for the Pebble Bed Modular Reactor (PBMR) currently being designed in South Africa, and for prismatic reactor concepts being developed in the USA and Europe. NBG-10 is one of several graphites included in the United States Department of Energy Very High Temperature Reactor program.
