  1. 1. Studies of Nuclear Fuel by Means of Nuclear Spectroscopic Methods

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Peter Jansson; Uppsala universitet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; irradiated nuclear fuel; nuclear spectroscopy; tomography; safeguard; Strålningsvetenskap; MEDICINE Physiology and pharmacology Radiological research Radiation biology; MEDICIN Fysiologi och farmakologi Radiologisk forskning Strålningsbiologi; Kärnfysik; Nuclear Physics;

    Sammanfattning : The increasing demand for characterization of nuclear fuel, both from an operator and authority point of view, motivates the development of new experimental and, preferable, non-destructive methods. In this thesis, some methods based on nuclear spectroscopic techniques are presented. LÄS MER

  2. 2. The effect of dissolved hydrogen on spent nuclear fuel corrosion

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Patrik Fors; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; alpha-doped; Nuclear waste repository; Hydrogen; Solubility; Corrosion; UO2; MOX; Spent nuclear fuel; High burn-up; Groundwater;

    Sammanfattning : In case of a canister failure in a deep bedrock repository for nuclear fuel, the release of radiotoxic nuclides to the groundwater will depend on the chemical environment near the fuel surface.Due to the presence of large amounts of iron in the canister, hydrogen will be formed if the canister becomes groundwater flooded.

  3. 3. A Tomographic Measurement Technique for Irradiated Nuclear Fuel Assemblies

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Staffan Jacobsson Svärd; Uppsala universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; tomography; nuclear fuel; SPECT; core physics; validation; pin power; safeguards; partial-defect verification; Kärnfysik; NATURAL SCIENCES Physics Nuclear physics; NATURVETENSKAP Fysik Kärnfysik;

    Sammanfattning : The fuel assemblies used at the Swedish nuclear power plants contain typically between 100 and 300 fuel rods. An experimental technique has been demanded for determining the relative activities of specific isotopes in individual fuel rods without dismantling the assemblies. LÄS MER

  4. 4. Applications of Gamma Ray Spectroscopy of Spent Nuclear Fuel for Safeguards and Encapsulation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christofer Willman; Uppsala universitet.; [2006]
    Nyckelord :Nuclear physics; gamma radiation; spectroscopy; spent nuclear fuel; safeguards; HRGS; MOX; Kärnfysik;

    Sammanfattning : Nuclear energy is currently one of the world’s main sources of electricity. Closely connected to the use of nuclear energy are important issues such as the nonproliferation of fissile material that may potentially used in nuclear weapons (safeguards), and the management of the highly radioactive nuclear waste.

  5. 5. Dynamics of Spent Nuclear Fuel Dissolution : Impact of Catalysis, Matrix Composition and Time Evolution

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Annika Carolin Maier; KTH.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : Worldwide, nuclear power produces a large portion of the electricity that we consume every day. While nuclear energy comes with certain advantages, waste originating from its use is of particular concern. LÄS MER
