    University essay from KTH/Fysik

    Author : Maria Giamouridou; [2023]
    Keywords : uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

    Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

  3. 2. 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

  4. 3. Effect of Proton Irradiation on the Mechanical Properties of Fe-10Cr-4Al in Liquid Lead

    University essay from KTH/Fysik

    Author : Gabriela Lapinska; [2023]
    Keywords : Fe-10Cr-4Al; Lead; Radiation Damage; Slow Strain Rate Testing; Fe-10Cr-4Al; bly; strålskador; Slow Strain Rate Testing;

    Abstract : Among the structural materials under consideration for future lead-cooled fastreactors, special attention is paid to ferritic Fe-10Cr-4Al due to its superior corrosionand erosion protective properties, as well as its insensitivity to liquid metalembrittlement in liquid lead. This thesis gives an inside look into the radiation damageproperties of the alloy and the possible embrittlement scenarios. READ MORE

  5. 4. Toxicity of Pulsed Beams in Radiation Therapy from a Physio-Chemical Perspective

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Karin Källén; [2021]
    Keywords : FLASH; radiotherapy; ultra high; dose rates; radiolysis; cancer; medical; FLASH; strålbehandling; ultrahög; doshastighet; radiolys; cancer; medicinsk;

    Abstract : A significant portion of cancer patients receive radiotherapy as part of their curative or palliative treatment plan. Radiotherapy is however greatly limited by radiation induced toxicities in healthy tissue surrounding the tumour, which can lead to long-term or acute complications for a patient. READ MORE

  6. 5. Correlation of microstructural damage to functional properties of irradiated carbon fibre based composites used in neutron chopper discs

    University essay from Lunds universitet/Hållfasthetslära

    Author : Hanna Molin; [2019]
    Keywords : radiation; epoxy; carbon fiber; CFRP; ESS; European Spallation Source; Technology and Engineering;

    Abstract : Understanding material behaviour has in the past enabled human development and will continue to characterize the various stages of our future development. The use of neutrons will greatly affect several research areas, such as sustainable energy production and cancer research, due to their interaction with nuclei. READ MORE
