Innovative methods of semi-destructive mechanical testing and their significance in the assessment of structural materials of NPP components degradation
Original language description
Within the nuclear power plant operational life management, current trend of components lifetime extension requires precise information of structural material degradation. Present-day methods of mechanical testing are usually based on the use of large specimens and higher consumption of scarce testing material. For determination of material properties, sampling of the necessary volume of material is in most cases connected with affecting the integrity or even destruction of the assessed component. Moreover, several components are not usually involved in surveillance programmes, e.g. reactor pressure vessel internals. Innovative testing methods of Small Punch Testing (SPT) and Automated Ball Indentation Test (ABIT) are based on the determination of material properties from sub-sized specimens and their semi-destructive approach is very promising for the possibility of present data base of irradiated materials testing results enlargement and enable the possibility of component in-situ te
