Workpackage 5
The degradation of the mechanical properties under neutron irradiation is the most significant effect with respect to the application of fusion reactor materials. Especially the embrittlement of the materials is strongly affected by the mobility of dislocations and their interaction with grain boundaries.
To investigate embrittlement effects at this level, micromechanical testing methods have to be developed or at least adapted which then produce useful quantitative results. On the other hand, the limited irradiation volume and the requirement to minimize the amounts of radioactivated materials lead to the need for tests on miniaturized specimens.
Both lines of development intersect at the point of methodology for micro- (and nano-) mechanical testing.
(Source: Österreichische Akademie der Wissenschaften)The activities of WP5 aim at the set-up of a consistent set of testing requirements which shall define the testing methods that are needed.
The aim of the cooperative activities is to further develop these testing methods and to validate them for use on radioactivated materials.
