First wall tile attachment using carbon-carbon composite fittings
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: 1. a low profile installation to optimize field efficiency; 2. tile alignment of sufficient precision to fully protect the VV, without adverse interference of the plasma; 3. adequate structural capacity to safely accommodate normal static and dynamic loads as well as disruption and handling loads; 4. 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; 5. a minimum irradiated life expectancy of 3,000 operating pulses; and 6. a reliable and repeatable method of replacing first wall tiles by means of a conventional remote manipulator device.
