  1. 1. Studies of Cherenkov light production in irradiated nuclear fuel assemblies

    Författare :Erik Branger; Sophie Grape; Anders Hjalmarsson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; DCVD; Cherenkov light; Geant4; Nuclear fuel; Nuclear safeguards; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : The Digital Cherenkov Viewing Device (DCVD) is an instrument used by authority inspectors to assess irradiated nuclear fuel assemblies in wet storage for the purpose of nuclear safeguards. Originally developed to verify the presence of fuel assemblies with long cooling times and low burnup, the DCVD accuracy is sufficient for partial defect verification, where one verifies that part of an assembly has not been diverted.

  2. 2. Enhancing the performance of the Digital Cherenkov Viewing Device : Detecting partial defects in irradiated nuclear fuel assemblies using Cherenkov light

    Författare :Erik Branger; Sophie Grape; Christopher Orton; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; DCVD; Nuclear safeguards; Cherenkov light; Nuclear fuel assembly; Partial defect verification; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : The Digital Cherenkov Viewing Device (DCVD) is an instrument used by authority safeguards inspectors to verify irradiated nuclear fuel assemblies in wet storage based on Cherenkov light emission. It is frequently used to verify that parts of an assembly have not been diverted, which is done by comparing the measured Cherenkov light intensity to a predicted one. LÄS MER

  3. 3. Fragment Mass Distributions in Neutron-Induced Fission of 232Th and 238U from 10 to 60 MeV

    Författare :Vasily Simutkin; Stephan Pomp; Franz-Josef Hambsch; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ADS; neutron-induced fission; intermediate neutron energies; fragment mass yield; Nuclear physics; Kärnfysik; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Since its discovery, the phenomenon of nuclear fission is the object of extensive theoretical and experimental studies. However, we are still far from a complete understanding of the fission process. LÄS MER

  4. 4. Approaching well-founded comprehensive nuclear data uncertainties : Fitting imperfect models to imperfect data

    Författare :Petter Helgesson; Henrik Sjöstrand; Helmut Leeb; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Evaluated nuclear data; uncertainty propagation; uncertainty quantification; model defects; Gaussian processes; TALYS; TENDL; covariances.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Nuclear physics has a wide range of applications; e.g., low-carbon energy production, medical treatments, and non-proliferation of nuclear weapons. Nuclear data (ND) constitute necessary input to computations needed within all these applications. LÄS MER

  5. 5. Neutron Spectrometry Techniques for Fusion Plasmas : Instrumentation and Performance

    Författare :Erik Andersson Sundén; Göran Ericsson; Sean Conroy; Erik Traneus; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; fusion; plasma diagnostics; neutron spectrometry; neutron spectroscopy; MPRu; magnetic proton recoil spectrometer; fusion; ITER; Nuclear physics; Kärnfysik; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Neutron are emitted from a deuterium plasma with energies around 2.5 MeV. The neutron spectrum is intimately related to the ion velocity distribution of the plasma. As a consequence, the analysis of neutron energy spectra can give information of the plasma rotation, the ion temperature, heating efficiency and fusion power. LÄS MER
