Surveillance programs were established to monitor reactor pressure vessels (RPV) in service of nuclear power plants (NPP). Regular testing of bainite-ferrite RPV steel is essential, since irradiation is known to cause degradation in mechanical properties as well as rising of the ductile-brittle transition temperature of body-centred cubic (bcc) steels. Surveillance impact testing is mainly performed with Charpy-V notch (CVN) specimens. The tested CVN specimen halves are feasible for manufacturing of miniature size Compact Tension (C(T)) specimens. The usage of miniature size C(T) specimens for determination of fracture toughness in ductile-brittle transition range is of great interest in NPP field and it is studied in this thesis. Presen...
