Streszczenie: The talk describes the investigations on high-Ni, high-Mn and low-Cu weld metals from the decommissioned Barsebäck 2 boiling water reactor (BWR) reactor pressure vessel (RPV). The reactor pressure vessel head (RPVH) weld and axial and circumferential beltline welds of the Barsebäck 2 RPV have been studied. The investigations include both mechanical testing (fracture toughness, impact toughness, tensile testing) and microstructural characterization but the talk will focus more on microstructure, fractography, primary initiation sites, the initiators of brittle fracture, and hardness through the RPV wall thickness.
