Flat tile armour cooled by hypervapotron tube: a possible technology for ITER
Carbon fibre composite (CFC) flat tile armours for actively cooled plasma facing components (PFC's) are an important challenge for controlled fusion machine. Flat tile concepts, water cooled by tubes, were studied, developed, tested and finally experienced with success in Tore Supra. The components were designed for 10 MW/m2 and mock-ups were successfully fatigue tested at 15 MW per square metre, 1000 cycles. For ITER, a tube-in-tile concept was developed and mock-ups sustained up to 25 MW per square metre for 1000 cycles without failure. Recently flat tile armoured mock-ups cooled by hypervapotron tube successfully sustained a cascade failure test under a mean heat flux of 10MW per square metre 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 flat tile concept when cooled by hypervapotron tube. New tests are now scheduled to investigate these limits notably in regards to the ITER requirements. The concept could also be experimented in Tore Supra by installing a new limiter into the machine.
