Infra-red thermography on Tore Supra, the French experimental reactor on nuclear controlled fusion
The thermographic system is a major diagnostic of Tore-Supra; its main role is to protect components such as limiters directly exposed to the very high temperature, exoenergetic, plasma. Three of the actively cooled limiters have been successfully tested in a steady state regime with surface temperatures under 1000 C. The design value for power removal has been obtained. Peak power fluxes of 10 MW/m2 (3.5 MW/m2 on average) have been estimated. This represents a breakthrough for high heat flux components since critical heat flux and burnout with subcooled flow boiling are major aspects for this kind of design. The time constant to reach a stablised temperature on the whole head is less than 2 seconds (shot duration = 10 seconds) as expected from modelling of heat transmission through the thin 2.5 mm graphite layer tile, to the water through the brazed joint.
