  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. Quantum-state Selective Nuclear Decay Spectroscopy

    Detta är en avhandling från Lund University

    Författare :Ch. Lorenz; Lund University.; Lunds universitet.; [2018-12]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; alpha decay; beta decay; gamma rays; spectroscopy; Penning traps; shell-model calculations; Geant4 Monte Carlo Simulations;

    Sammanfattning : This thesis focusses on the results of two experiments employing Penning traps to prepare pure beams of the 213Ra ground state and 127Cd, which were then studied with the decay-spectroscopy setup TASISpec. The experiments were conducted with SHIPTRAP at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, and JYFLTRAP at the IGISOL Accelerator Facility at the University of Jyväskylä, Finland.

  4. 4. 14C Produced by Nuclear Power Reactors - Generation and Characterization of Gaseous, Liquid and Solid Waste

    Detta är en avhandling från Division of Nuclear Physics Department of Physics Lund University Box 118 SE-221 00 Lund Sweden

    Författare :Åsa Magnusson; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; waste disposal; spent ion-exchange resins; mass balance assessment; Nuclear physics; environmental impact; Fysicumarkivet A:2007:Magnusson; nuclear power plant; Kärnfysik; Carbon-14;

    Sammanfattning : This thesis presents the results from studies on carbon-14 produced by nuclear power reactors. Radioactive 14C enters the carbon cycle and can be taken up by humans, where it will constitute a potential health hazard. LÄS MER

  5. 5. Development of the Lund AMS Facility for the Detection of 59Ni – with Applications in the Nuclear Industry

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Per Persson; Lund University.; Lunds universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AMS; Accelerator mass spectrometry; 59Ni; nuclear waste; chemical cobalt reduction; gas stripper; Nuclear engineering and technology; Kärnteknik; Fysicumarkivet A:2002:Persson;

    Sammanfattning : Accelerator mass spectrometry (AMS) is a highly sensitive method for counting atoms and it is used for detecting very low concentrations of both radionuclides and stable isotopes in small samples. The two major advantages of the AMS method are that the required amount of sample material is very small, but also that the efficiency is rather high, it takes less than an hour to analyse a sample.
