Infrared thermography inspection of the ITER vertical target qualification prototypes manufactured by European industry using SATIR

摘要

High heat flux loaded components which will be installed in the ITER Divertor require a heat flux removal capability in the range 5-10MW/m~2 at steady-state and up to 20MW/m~2 in transients. Within the ITER plasma facing components procurement context, each party should demonstrate its technical capability to carry out the manufacturing with the required quality. This is achieved through the successful manufacturing and testing of medium-size qualification prototypes. Each Qualification Prototype consists of three high heat flux units mounted onto an actively cooled supporting structure. Currently, the SATIR method has been identified by the ITER Organization as the basic test to decide upon the final acceptance of the ITER Divertor components. SATIR testing was performed on each CFC part of European HHF units prior to the insertion of the twisted tape and prior to assembling the units onto the steel support structure. The paper deals with SATIR results of all qualification prototypes manufactured by European industry.
