Abstract

A multiplicity of pebble-bed cores are housed within separate concrete cavities of a multi-cavity prestressed concrete pressure vessel. Primary cooling systems, one for each pebble-bed core, are supported within another cavity which is coaxial with the longitudinal axis of the prestressed concrete pressure vessel. Tunnel ducts formed within the walls of the concrete vessel communicate between the cavities which house the pebble-bed cores and the cavity which houses the primary cooling systems. Pipes connecting the cores to the primary cooling systems pass through these ducts.
