ABSTRACT
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. | ||||
| 6. | A reliable and repeatable method of replacing first wall tiles by means of a conventional remote manipulator device. | ||||
