abstract = {A dedicated procedure was developed to categorize the
technology readiness of materials for specific DEMO
in-vessel fusion reactor applications. This methodology was
employed to assess the technological maturity of materials
under development within the EUROfusion materials work
package (WPMAT). This covers materials intended for
structural, high heat flux, optical and dielectric
applications in the European DEMO fusion reactor (breeder
materials and barrier coatings are not covered here). The
baseline materials have been assigned DEMO Material
Technology Readiness Levels (MTRLs) of 4 (EUROFER97), 3
(conventional tungsten) and 4 (Copper-Chromium-Zirconium).
In addition, a further 28 candidate materials (and groups of
materials) were also assessed. These were generally assigned
DEMO MTRLs in the range of 2-3. This process has highlighted
the wide range of materials under development within WPMAT.
However, it has also brought into focus the many challenges
facing DEMO materials development. While the lack of
technologically ready materials is clearly a source of risk
to DEMO, the introduction of a biennial review of technology
readiness within WPMAT is intended to facilitate more
effective planning and targeted materials development, in
line with the strategic plans of EUROfusion. This paper
highlights the methodologies for fusion specific material
technology readiness levels, their application for EU-DEMO
and the effectiveness of these in strategic materials
development.},
