Fusion Engineering Device (FED) Configuration and Maintenance

摘要

This paper addresses the subject of how the FED baseline configuration provides for replacement of major machine components in the event of wear-out or failure. The maintenance aspects of the configuration are emphasized. Specifically, removal/replacement scenarios and their associated time spans are summarized for twelve major FED cmponents. These scenarios were developed concurrently with the development of the baseline configuration to assure conformance with maintenance requirements. The results show that eight of the twelve components investigated are amenable to straightforward removal and replacement techniques which can be performed in 45 days or less. Two additional components, the TF coils and one PF coil, exhibit relatively straightforward removal/replacement characteristics but require an extensive time span as a consequence of the large amount of intervening equipment which must also be removed and replaced.
