Beschreibung
Zusammenfassung:	The invention relates to a manufacturing method of mass producing fuel elements configured for use in a high-temperature gas cooled reactor core, the method comprising using additive manufacturing methods and robotic mechanisms to control spatial placement and packing density of particles within a matrix of graphite, wherein the particles comprise one or more of fuel material, burnable poison material, or breeder material. Fuel elements may be spherical fuel pebbles. Fuel particles may be tri-structural-isotropic particles without an overcoat.
