Abstract
COOLING THE INTERNALS OF FUSION REACTORS IS LARGELY DEPENDENT UPON RADIATION. THE HIGH VACUUM CONDITIONS ELIMINATE CONVECTION COOLING AS AN OPTION, AND FRAGILE MATERIALS AND LARGE DIFFERENTIAL THERMAL EXPANSIONS MAKE CONTACT CONDUCTANCE PROBLEMATIC. THIS RESEARCH IS DESIGNED TO ENHANCE THE RADIATION RATE ACROSS MECHANICAL JOINTS IN A VACUUM ENVIRONMENT. CONCEPTS DEVELOPED FOR THE COMPLIANT ATTACHMENT OF HOT TILES AND HEAT TRANSFER CONCEPTS DEVELOPEDFOR CONDUCTION ACROSS JOINTS IN SPACECRAFT RADIATORS ARE COMBINED TO ADDRESS THIS CONCERN. ANALYTICAL MODELS WILL BE DEVELOPED TO COVER THE RANGE OF DESIGN VARIABLES. IN-VACUUM TESTS WILL BE CONDUCTED TO SUPPORT THE ANALYTICAL AND DESIGN EFFORTS.
