"The design and optimisation of a monoblock divertor target for DEMO using thermal break interlayer"

F. Domptail T.R. Barrett M. Fursdon A. Lukenskas J-H. You

A high performing DEMO divertor target mock-up design that uses the thermal break interlayer concept is presented.  The design evolved from a previous design of which six mock-ups were designed, fabricated and subjected to high heat flux testing.  The new design was generated using optimisation techniques; specifically, software was developed …

"Comparison of X-ray and neutron tomographic imaging to qualify manufacturing of a fusion divertor tungsten monoblock"

Llion Evans T. Minniti M. Fursdon M. Gorley T. Barrett F. Domptail E. Surrey W. Kockelmann A.v. Müller F. Escourbiac A. Durocher

Within a tokamak fusion energy device, the performance and lifespan of a divertor monoblock under high heat flux cycles is of particular interest. Key to this is the quality of manufacture, especially the material joining interfaces. Presented here is a comparative study between X-ray and neutron tomography to investigate the quality of manufacture…

"Progress in the Engineering Design and Assessment of the European DEMO First Wall and Divertor Plasma Facing Components"

T. R. Barrett G. Ellwood G. Pérez M. Kovari M. Fursdon F. Domptail S. Kirk S.C. McIntosh S. Roberts S. Zheng L.V. Boccaccini J-H. You C. Bachmann J. Reiser M. Rieth E. Visca G. Mazzone F. Arbeiter P.K. Domalapally

The European DEMO power reactor is currently under conceptual design within the EUROfusion Consortium. One of the most critical activities is the engineering of the plasma-facing components (PFCs) covering the plasma chamber wall, which must operate reliably in an extreme environment of neutron irradiation and surface heat and particle flux, while …
