Neutronics Analysis for Integration of ITER Diagnostics Port EP10

Shutdown dose rate calculations have been performed on an integrated ITER C-lite neutronics model with equatorial port 10. A fully shielded configuration, optimized for a given diagnostic designs (i.e. shielding in all available space within the port plug drawers), results in a shutdown dose rate in the port interspace, from the activation of materials comprising equatorial port 10, in excess of 2000 µSv/h. Achieving dose rates of 100 µSv/h or less, as required in areas where hands-on maintenance can be performed, in the port interspace region will be challenging. A combination of methods will need to be implemented, such as reducing mass and/or the use of reduced activation steel in the port interspace, optimization of the diagnostic designs &; shielding of the port interspace floor. Further analysis is required to test these options and the ongoing design optimization of the EP10 diagnostic systems.
