  3. 2. Studies of Accelerator-Driven Systems for Transmutation of Nuclear Waste

    Författare :Marcus Dahlfors; Ane Håkansson; Alfred Hogenbirk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; transmutation; accelerator-driven systems; Energy Amplifier; subcritical reactors; nuclear waste; Monte Carlo simulation; burnup; actinides; fission products; benchmark; nuclear data; neutron cross sections; sensitivity analysis; neutron source; spallation target; n_TOF experiment; neutron time-of-flight; cross section measurement; FLUKA; EA-MC; MCNP; MCNP-X; EADF; TRADE; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : Accelerator-driven systems for transmutation of nuclear waste have been suggested as a means for dealing with spent fuel components that pose potential radiological hazard for long periods of time. While not entirely removing the need for underground waste repositories, this nuclear waste incineration technology provides a viable method for reducing both waste volumes and storage times.

  5. 4. 14C Produced by Nuclear Power Reactors - Generation and Characterization of Gaseous, Liquid and Solid Waste

    Författare :Åsa Magnusson; Kärnfysik; []
    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

  7. 5. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries

    Författare :Torbjörn Gäfvert; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kärnfysik; Nuclear physics; zircon; ceramics industry; thorium; TIG welding; waterworks; calcium chloride; dicalcium phosphate; phosphate industry; non-nuclear industries; TENORM; Natural radioactivity; NORM;

    Sammanfattning : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. LÄS MER
