Abstract: The invention relates to a method and device for measuring hydridation kinetics at different temperatures in tubular industrial components. The invention consists in measuring the power dissipated by a hydridation reaction over time as well as the variation in the electric resistance during said reaction. The inventive method and device can be used to optimise industrial components, such as tubes and fuel claddings for nuclear reactor cores. In this way, safety is increased, with the prevention of unplanned shutdowns of commercial reactors and a decrease in high-activity nuclear waste.
