Abstract

Carbon fibre composite (CFC) flat tile armours for actively cooled plasma facing components (PFC�s) are an important challenge for controlled fusion machines. Flat tile concepts, water cooled by tubes, were studied, developed, tested and finally operated with success in Tore Supra. The components were designed for 10MW=m2 and mock-ups were successfully fatigue tested at 15MW=m2; 1000 cycles. For ITER, a tube-in-tile concept was developed and mock-ups sustained up to 25MW=m2 for 1000 cycles without failure. Recently flat tile armoured mock-ups cooled by a hypervapotron tube successfully sustained a cascade failure test under a mean heat flux of 10MW=m2 but with a doubling of the heat flux on some tiles to simulate missing tiles (500 cycles).
This encouraging results lead to reconsider the limits for .at tile concept when cooled by hypervapotron (HV) tube. New tests are now scheduled to investigate these limits in regard to the ITER requirements. Experimental evidence of the concept could be gained in Tore Supra by installing a new limiter into the machine.
