© 2020 National Research Center Kurchatov Institute. All rights reserved.3D modeling of neutron associated processes is performed to assess radiation loads in the area of the first mirror unit (FMU) of H-Alpha and Visible Spectroscopy Diagnostic located in ITER Equatorial port #12, including neutron/gamma and total heating, and absorbed dose rate in the FMU components. A temperature analysis of the structure elements is done being based on the nuclear heating data. Calculations are based on the latest ITER 40ºneutronic C-Model and highly detailed FMU model developed using code SuperMC. The highest nuclear heat load 0.8 W/cm3 is derived for the front-end wall of the First Mirror Unit. Thermal analysis shows low temperature gradient around 50 °C in FMU housing area. Maximum temperature obtained does not exceed 460 °C on the front-end wall of the FMU.
