Thermal Contact Conductance (TCC) in Vacuum

The thermal loading of the Blanket system is mainly due to plasma surface heating (radiation & convection) and volumetric neutron heating. A pressurized water circuit flowing through the main components (First Wall and Shield Blocks) allows cooling down the system. But some elements (pads, bolts, etc.) imbedded in the system are only cooled by thermal contact (and radiation) to the main water-cooled components, this conduction needs to be quantified accurately according to blanket operational conditions. The present tender process is aiming to set up a Service Contract for the accurately measuring of the TCC for different material coated and not coated with the EIC (Electrical Insulating Coating) and threads used in the Blanket in vacuum conditions.
