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

    Författare :Peter Jansson; Roland Carchon; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; irradiated nuclear fuel; nuclear spectroscopy; tomography; safeguard; Strålningsvetenskap; Radiation biology; 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. Gendering Nuclear Disarmament : Identity and Disarmament in Sweden during the Cold War

    Författare :Emma Rosengren; Thomas Jonter; Yvonne Svanström; Cecilia Åse; Towns Ann; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Feminist theory; nuclear disarmament; nuclear weapons; gender nation sexuality; identity and policy; International Relations; internationella relationer;

    Sammanfattning : This dissertation provides new knowledge about gender, nuclear weapons and disarmament. Previous feminist research has shown that in contexts where positive associations are made between military strength, masculinity and nuclear weapon possession, it is hard to imagine nuclear renunciation and disarmament as anything other than potential emasculation or feminization.

    Sammanfattning : The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and 60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy, and thereby connected it to utopian ideas about an eternal supply of energy. LÄS MER

    Sammanfattning : This thesis concerns a nuclear accident that occurred in the Thule (Pituffik) area, NW Greenland in 1968, called the Thule accident. Results are based on different analytical techniques, i.e. gamma spectrometry, alpha spectrometry, ICP-MS, SEM with EDX and different sediment models, i. LÄS MER
