Advanced qualification methodology for actively cooled plasma facing components

Résumé

The use of high heat flux plasma facing components in steady state fusion devices requires high reliability. These components have to withstand heat fluxes in the range of 10-20 MW/m2 involving a number of severe engineering constraints. Experience feed back of various industrial manufacturing showed that the bonding of the refractory armour material onto the metallic heat sink causes generic difficulties strongly depending on materials qualities and specific design. As heat exhaust capability and lifetime of plasma facing components during plasma operation are directly linked to the manufacturing quality, a set of qualification activities was performed during the component development phases following a qualification route. The paper describes the major improvement stemming from better measurement accuracy and refined data processing and analyses recent developments aim at investigating the capability to qualify the component in situ during its lifetime.
