ABSTRACT:
A guide ring is positioned in the reactor core vessel of a pebble-bed nuclear reactor to segregate fuel pebbles and reflector pebbles fed into the vessel through respective conduits. The reflector pebbles pass through the guide ring and form a central reflector column, while the fuel pebbles pass outside the guide ring and form an annular fuel column surrounding the central reflector column. The guide ring controls the size and shape of the reflector column and controls mixing of the two types of pebbles.
