The Diagnostic First Walls (DFWs) were designed to handle the plasma nuclear and radiant heating along with electro-magnetic loading induced from disruptions. DFWs also provide custom viewing apertures for diagnostics within. Consequently, contain numerous complex water cooling channels are per ITER SDC-IC design by analysis.This paper presents analyses of Upper Port proceeding a final review. finite element (FEAs) performed include neutronics, radiative heating, coupled fluid dynamics heat transfer, static transient structural analysis using combined multi-physics load conditions. Static FEAs account dynamic amplification effects load. A detailed bolt was evaluation based on reaction loads obtained mechanical simulations.
