Abstract
The mechanical properties of spallation target components exposed to combined effects of proton and
neutron irradiations and in contact with liquid metal provide important information for the assessment
of structural component integrity, which is crucial for the design of accelerator driven reactor concepts
such as the MYRRHA reactor. In this study we perform tensile tests on T91 steel samples extracted from
the MEGAPIE, and from the TWIN-ASTIR experiment. The tests are performed at different temperatures
as well as with and without the contact with liquid metal. In both groups of samples we observed
significant influence of liquid metal on the tensile properties, in particular reduction of total elongation.
The influence of different conditions in two irradiation programs on the mechanical properties, such as
irradiation temperature fluctuations, the presence of neutron/proton irradiation, with and without the
contact with lead-bismuth eutectic, different flux and fluence, are also discussed.
