Description
This paper presents the results of a study that was performed on conceptual solutions for assembly and handling of EC components inside the EC upper and equatorial port cells. Particular topics that are discussed include the access to the waveguides and auxiliary feedthroughs of the launchers at the port plug closure plate, (dis-)assembly & alignment of the ex-vessel waveguide in the port interspace via a ceiling support structure in the port cell and procedures for handling and alignment of the individual segments of the first confinement ex-vessel transmission lines.
The ITER Tokamak will become activated over time, leading to non-negligible shutdown dose rates, mainly inside the port cell interspaces. To minimize dose uptake for maintenance personnel, ITER requires that the design of ex-vessel equipment is optimized to keep maintenance time short and exposure levels ALARA (as low as reasonably achievable). In order to achieve this, some of the design principles and guidelines for Remote Handling (RH) compatibility are applied to ex-vessel EC components. This helps to ensure that all dismountable interfaces have good accessibility both by man and machine and that all maintenance tasks are well documented, rehearsed and can be demonstrated either through Virtual Reality simulation or through hardware mock-up.
