Section: abstract

A compression hub (10) for use in a fusion reactor system comprising a multiplicity of compression plates (24, 24') that are polygonal in configuration, and which are arranged in vertically stacked, substantially abutting relation to each other. The compression plates (24, 24') are suitably interconnected, such as by welding, around the periphery thereof so as to provide a compression hub (10) that is in the form of a unitary structure. Each of the compression plates (24, 24') is provided with fluid flow means (30, 32, 30', 32'). The fluid flow means (30, 32, 30', 32') of the compression plates (24, 24') cooperate with one another to establish a fluid flow path for coolant through the compression hub (10). Each of the compression plates (24, 24') is further provided with eddy current prevent means operable to impede the circulation through the plates (24, 24') of eddy currents induced by changes in the magnetic flux field. The eddy current prevent means comprises one or more interruptions formed in each of the compression plates (24, 24') so as to extend completely therethrough.
