Beryllium is used as neutron multiplier in the form of a pebble bed. Basic characteristics of the beryllium pebbles are required to the design of blanket. From this point view, production methods and basic characteristics including particle morphology and mechanical properties of beryllium pebbles were investigated. The paper gives a brief description of fabrication technology for the Be pebbles. The Plasma Rotating Electrode Process (PREP) is the method for producing 1–1.2 mm Be pebbles for use as a neutron multiplier. The obtained results indicate the advantages for the fabrication of Be pebbles and the excellent properties of the pebbles.
