Three pathways to commercial fusion based on a tokamak driver have been developed and analyzed. These pathways are identified as 1) the fusion electric, 2) the fusion-fission hybrid, and 3) the integrated electric hybrid pathways. The analyses of the various pathways show significant differences in technology requirements. In developing these pathways special emphasis has been placed on the next device in the hybrid pathway which would follow TFTR. As part of this study a first version of the Fusion Technology Capabilities Compendium has been assembled. The compendium includes the driver, blanket, and fuel cycle technologies and it provided background information which has been used to identify critical R&D needs for a 1990's hybrid device.
