  SATIR is a new test-bed installed at Tore Supra to perform non destructive
examination of actively cooled plasma facing components. Hot and cold water
flow successively in the cooling tube of the component and the surface
temperature is recorded with an infrared camera. Defects are detected by a
slower temperature response above unbrazed areas. The connection between
temperature differences and defect sizes is the main difficulty. It is
established by tests of standard defects and thermal transient calculations of
defective geometries. SATIR has been in use for two years and has proved to be
very valuable to test industrial components as well as prototypes.
