Comparison of Conventional Mechanical Testing with Innovative Techniques for Determination of Mechanical Properties of Nuclear Power Plant Components Materials

摘要

Within the nuclear power plant operational life management, components lifetime extension requires information on structural material degradation. Innovative testing methods of Small Punch and Automated Ball Indentation tests are based on the determination of material properties from sub-sized specimens. This paper is focused on the employment of these techniques in nuclear power plant materials testing and evaluation at the accredited hot cell testing laboratory of UJV Rez, a. s., Mechanical Testing Department. A comparison with the testing results from the conventional methods is depicted.
