°ÄÃÅÁùºÏ²Ê¸ßÊÖ

The aim of the WEST project is to turn the Tore Supra tokamak (France) into a test bed for °ÄÃÅÁùºÏ²Ê¸ßÊÖ, with an actively cooled °ÄÃÅÁùºÏ²Ê¸ßÊÖ-like tungstendivertor.

Component installation is underway. The latest WEST Newsletter (#11) reports on the most recent milestone: the installation of the divertor coil casings. Two stainless steel rings constituting the housing for the conductor windings are now assembled and positioned inside the vacuum vessel at their nominal position. The building of the coil winding can now begin.

An 18-month development program to prototype remote handling tooling for the °ÄÃÅÁùºÏ²Ê¸ßÊÖ fusion device was demonstrated on 26 and 27 October as part of collaboration between the European Domestic Agency for °ÄÃÅÁùºÏ²Ê¸ßÊÖ and the Culham Centre for Fusion Energy (CCFE) in the UK.

Representatives from the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization, the European agency, Assystem UK, and AMEC Foster Wheeler were at Culham to see a fully remote deployment of prototype remote pipe cutting and welding tooling developed by Culham's RACE (Remote Applications in Challenging Environments).

Under a grant from the European Domestic Agency, RACE and CCFE's Engineering Implementation Department have produced a set of prototype tools intended for eventual use maintaining the neutral beam heating systems at °ÄÃÅÁùºÏ²Ê¸ßÊÖ. Up to now, remote cutting and welding of process piping to the required codes, and under the challenging conditions of the °ÄÃÅÁùºÏ²Ê¸ßÊÖ tokamak, had not been demonstrated, and is one of the higher risk areas across the °ÄÃÅÁùºÏ²Ê¸ßÊÖ remote maintenance strategy.

°ÄÃÅÁùºÏ²Ê¸ßÊÖ will rely on remote handling for maintenance operations where space and/or environmental conditions in the machine do not allow manual intervention. Interconnected components, pipes, cranes and tooling will all need to be routinely repaired and maintained with millimetric accuracy.
