The development of a specific materials database and handbook, for engineering design of in-vessel components of EU-DEMO, is an essential requirement for assessing the structural integrity by design. For key in-vessel materials, including EURFOER97, CuCrZr, Tungsten and dielectric and optical materials, this development has been ongoing now within …

There is currently a European collaboration that is working towards developing a Demonstration Fusion Reactor (European DEMO). This project is currently defining the high level plant architecture of a DEMO reactor, whilst developing conceptual design solutions for technically challenging systems. One such area of development is the design of Pla…

Ti-containing micro-alloyed steels are often alloyed with molybdenum (Mo) to gain superior ageing-resistance through reduced nano-precipitate coarsening, although the exact mechanism is still disputed. Using small angle neutron scattering (SANS), we characterize precipitate composition and coarsening in Ti micro-alloyed steels with and without M…

Two high purity tungsten powders, produced via different manufacturing techniques, were characterized to determine size distribution, morphology, thermal properties and flow characteristics and thus, the likely suitability for Laser Powder Bed Fusion (LPBF) production. Specimens from duplicate builds were produced with the two powders and character…

The current paper reports the work of the EUROfusion Material Database and Handbook group within the MAT-EDDI (Materials – Engineering Data and Design Integration) subproject of the EUROfusion consortium. A special emphasis is put on the building of the EUROfusion RAFM steel database accounting around 3000 raw materials data records. A dat…

Eurofer 97 is the main structural material targeted for the DEMO reactors which will be operated under magnetic fields. It is therefore imperative to understand the effect of magnetic fields on the mechanical properties of the Eurofer 97. Here we preform 30 uniaxial tensile tests with and without a 1.5 T magnetic field at room temperature. The stat…

A comprehensive, standardised approach to high heat flux testing of materials is proposed, which allows for standardised data capture and comparison of measurements across global testing sites and setups. A meta-analysis of data for tungsten, with data re-captured in that format, highlights interesting trends with respect to appropriate damage metr…

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…
