Description

After the preliminary exploring phases for devising initial design concepts and performing design studies, the divertor project (WPDIV) of the EUROfusion consortium is currently entering into the final stage of the first half R&D round which is planned to be completed by the end of 2016. The core missions of WPDIV are to deliver feasible pre-conceptual design solutions for the divertor of an early DEMO reactor, to develop key technological elements needed to materialize the design concept and to verify the required high-heat-flux performance of the selected target concepts. In WPDIV two subprojects were installed: ‘Cassette design and integration’ and ‘Target development’. In the subproject ‘Cassette’ the overall system architectures of a cassette body are engineered whereas in the subproject ‘Target’ advanced design concepts and technologies are developed for the plasma-facing components. In this contribution, a brief overview is given on the recent progress achieved in the R&D activities. Major progress to be highlighted in this presentation includes: the thermo-hydraulic design of cassette cooling schemes, multi-physics analysis of cassette loads, cassette interior design, CAD models for fixation supports and coolant piping, novel design concepts for the plasma-facing target components, modelling of structural failure, engineering solutions for mock-up fabrication, non-destructive inspection of mock-ups and the first high-heat-flux test campaign (if available by then). Finally, impact of the divertor design requirements on the R&D programs of the related work packages (e.g. high-heat-flux materials, structural design rules, remote handling, etc.) is discussed.
