Abstract

At the extreme conditions expected for some operating scenarios of the International Thermonuclear Experimental Reactor, commonly used heat-removal structures are unable to withstand either the high sputter erosion rates or power loads. Solutions to these lifetime and reliability problems by (1) changes in machine design and operation, (2) redeposition mechanisms, and (3) changes in materials, will be discussed. A proposed accelerated-life test facility for prototype divertor plate development is described.
