  3. 2. 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

  4. 3. Conditional Progress: Technical Rationality and Wicked Problems in Nuclear Waste Management

    Författare :Hannes Lagerlöf; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nuclear waste management; science and technology studies; critical constructivism; sociology; technical rationality; reification;

    Sammanfattning : While various states and enterprises have produced nuclear power for decades, that is, demonstrated the functionality of the nuclear fuel cycle from uranium mining to power production, the waste that is simultaneously produced has been provisionally stored awaiting a safe solution. Still, no country has implemented such a solution. LÄS MER

  5. 4. Friction stir welding of copper canisters for nuclear waste

    Författare :Therese Källgren; Rolf Sandström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction Stir Welding FSW ; Copper; Welding; Finite Element Method FEM ; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The Swedish model for final disposal of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. One of the methods to seal the copper canister is to use the Friction Stir Welding (FSW), a method invented by The Welding Institute (TWI). LÄS MER

  7. 5. Mechanical Properties of Welds at Creep Activation Temperatures

    Författare :Henrik C.M. Andersson-Östling; Rolf Sandström; Kamran Nikbin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; creep; creep crack propagation; OFHC copper; welds; nuclear waste disposal; creep modeling; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Welds in materials intended for service at temperatures above the creep activation temperature often develop damage before the base metal. The weld is a discontinuity in the material and stresses and strains often accumulate in the weld. Knowledge of the properties of the weld is essential to the safe operation of the component containing the weld. LÄS MER
