SPEED-ASTIR: the development of an irradiation experiment for ADS Steel T91.

Research output: ThesisMaster's thesis


SPEED-ASTIR is one of the material experiments defined in the MYRRHA R&D support programme and is embedded in the FP6 EUROTRANS integrated project and in particular in the domain 4 of the project namely DEMETRA, in which structural materials and lead/lead-bismuth technologies are developed in support for transmutation in ADS systems. The aim of the experiment SPEED-ASTIR is the assessment of T91-steel, being simultaneously in contact with lead-bismuth at 450°C and exposed to high-energy neutrons up to 1 to 3.6 dpa. The goal of this thesis is to address in more detail the thermo-hydraulic analysis of the experimental rig, the development and the validation of the temperature control system and the development of the necessary control and features to prevent the accidental release of polonium-210.
