  1. 1. Irradiation Embrittlement on a Core Shroud from Decommissioned BWR

    University essay from KTH/Fysik

    Author : Åsa Bjåland; [2023]
    Keywords : hardness; Vickers hardness test; ATT; yield strength; irradiation embrittlement; welds; hårdhet; Vickers hårdhetstest; ATT; sträckgräns; bestrålningsförsprödning; svetsar;

    Abstract : Irradiation embrittlement is a problematic issue for internal structures, such as acore shroud, in a light water reactor. It is characterized by decreased ductility andtoughness, and increased yield strength and hardening due to increased dislocations. READ MORE
