    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. The Kinetics of Water Removal From an Iron Ore Pellet Prior to Hydrogen Reduction

    University essay from KTH/Materialvetenskap

    Author : Maja Andersson; Jonathan Garte; Johan Karlsson; [2023]
    Keywords : ;

    Abstract : Humanity is facing one of the biggest challenges ever presented in fighting climate change. To counter global warming, industries and scientists across the world are shifting manufacturing towards fossil independence in order to decrease emissions. READ MORE

  4. 3. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

    University essay from KTH/Materialvetenskap

    Author : Felix Göttfert; [2023]
    Keywords : Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Heat Transfer; Thermal Conductivity; Thermophysical Properties; Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Värmeöverföring; Termisk konduktivitet; Termofysiska egenskaper;

    Abstract : Steel has played an indispensable role in shaping our contemporary world  and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. READ MORE

  5. 4. Preliminary experimental study on the affect of water of the hydrogen reduced hematite pellet

    University essay from KTH/Materialvetenskap

    Author : Henrik Welander; [2021]
    Keywords : ;

    Abstract : Global warming is one of the most important challenges that we are facing today. Since carbon dioxide (CO2) is by far our most common green house gas pollutant,  most large corporations need to reconsider how their production is performed to keep the global warming below 2 ◦C.

  6. 5. Experimental study of the temperature profile in an iron ore pellet during reduction using hydrogen gas

    University essay from KTH/Materialvetenskap

    Author : Julia Brännberg Fogelström; [2020]
    Keywords : Iron ore; Iron oxide; Hematite pellet; Hydrogen reduction; Reduction; Intraparticle temperature; Temperature effect; Temperature profile; Järnmalm; Järnoxid; Hematitpellet; Vätgasreduktion; Reduktion; Invändig temperatur; Temperatureffekt; Temperaturprofil;

    Abstract : We are facing an important challenge, to reduce the greenhouse gas emissions to make sure that we limit global warming to 2 °C, preferably 1.5 °C. Drastic changes and developing new methods may be our only chance to keep global warming under 1.5 °C. READ MORE
