Abstract

Preliminary Design of Remote Handling Connector and Ancillary Components
F4E grant: F4E-OPE-0829. Remote Handling Connector (RHC) system is part of ITER in-vessel diagnostic components. The main function of this system is to route the electrical sensor signals from the divertor area up to the tokamak vacuum boundary. There are 16 diagnostic cassettes out of 54 divertor cassettes with five different RHC configurations. The RHC system operates in high vacuum, high irradiation and high temperature conditions. The system is connected in a limited space via remote handling during the installation of the diagnostic divertor cassettes. Despite strict space limitations, the design of the RHC system considers proper remote handling capabilities and interfaces for in-vessel manipulator operations. VTT has been working on the Preliminary Design of Remote Handling Connector and Ancillary Components. This continues the work done in the conceptual design phase of the system, where the architecture of the RHC system and the outboard and inboard configurations were decided. The preliminary design is highly impacted by finding an appropriate balance between the external and internal space limitations and system requirements. The design of the system has been an iterative process including mechanical design, thermal, magnetic and structural load analysis, risk analysis, and remote handling assessment. Manufacturing and testing mock-ups verified the design alternatives and adaptation to remote handling. Test environments included Divertor Test Platform 2 (DTP2) and Remote Handling Connector Platform (RHCP) in VTT heavy laboratory. Development of the system followed the official ITER and F4E PDR processes. PDR review meeting was organized at the end of 2019. The current focus of the project is in the closure of the PDR phase by resolving chits raised during the review meeting. The scope of the PDR phase is to provide the baseline for the final design of the RHC system.
