Evaluating the mechanical properties of structural materials of primary plant components is a key factor for reliable integrity assessments and correct life predictions. Materials which are subject to degradation of mechanical properties due to high temperature exposure, aggressive environment or neutron irradiation, have to be characterised in a reliable and not too conservative way. The evaluation of mechanical properties (with the exception of hardness measurements) is by definition a destructive technique, which however can be made semi-destructive is the sample size is so small that easy repair or even no repair is needed to allow further operation of the component.This presentation reviews several small-specimen test techniques, which have been developed, qualified and applied for the mechanical characterization of reactor pressure vessel steels, in both unirradiated and irradiated condition, within the Reactor Material Research department of the Belgian Nuclear Centre (SCK•CEN).
