This paper presents unique first wall tile attachment concepts of round or square graphite tiles to an Inconel 625 vacuum vessel (VV) with carbon-carbon (c-c) structural/mechanical elements to satisfy the following objectives.
- A low profile installation to optimize field efficiency.
- Tile alignment of sufficient precision to fully protect the VV, without adverse interference of the plasma.
- Adequate structural capacity to safely accommodate normal static and dynamic loads as well as disruption and handling loads.
- A tile and tile shank-to-VV wall stud mechanical interface that provides an acceptable level of conductive heat transfer while accommodating freedom of thermal expansion and contraction.
- A minimum irradiated life expectancy of 3,000 operating pulses.
- A reliable and repeatable method of replacing first wall tiles by means of a conventional remote manipulator device.
