    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. 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

  4. 3. 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
