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

    Author : Peter Jansson; Roland Carchon; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; irradiated nuclear fuel; nuclear spectroscopy; tomography; safeguard; Strålningsvetenskap; Radiation biology; Strålningsbiologi; Kärnfysik; Nuclear Physics;

    Abstract : 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. READ MORE

  5. 3. Segmented HPGe detectors for post-irradiation examination of nuclear fuel : Design and demonstration in gamma emission tomography

    Author : Vikram Rathore; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Andrew Boston; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Segmented HPGe detector; Nuclear fuel; Post-irradiation examination; Nuclear fuel diagnostics; Gamma emission tomography; Gamma spectroscopy; Non-destructive fuel testing; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : Gamma emission tomography (GET) is a proven non-invasive technique for post-irradiation examination of nuclear fuel. In the past, collimated HPGe detectors were used for GET measurements due to their good energy resolution. READ MORE

  6. 4. Internal Dosimetry in Nuclear Fuel Fabrication : Occupational Exposure to Uranium Aerosols

    Author : Edvin Hansson; Mats Eriksson; Håkan Pettersson; Per Roos; Michael Sandborg; Bastian Breustedt; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Uranium; Aerosol; Internal; Dose; Nuclear;

    Abstract : The production of nuclear fuel can be associated with occupational exposure to ionizing radiation from radioactive decay of uranium. Such exposure must be sufficiently low and radiation doses adequately determined. Radiation doses from internal exposure, i.e. READ MORE

  7. 5. Nuclear safeguards directed to the application of multivariate analysis techniques to existing and future nuclear fuel cycles

    Author : Vaibhav Mishra; Sophie Grape; Zsolt Elter; Erik Branger; Peter Dendooven; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear safeguards; nuclear fuel verification; spent fuel; molten salt reactors; machine learning.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : For as long as nuclear power has existed, there has been a concern for effectively safeguarding nuclear material since it was learned that it could be misused. Early on, many nations were interested in nuclear power, and therefore there was an urgent need to verify that it was only used for civilian purposes. READ MORE
