  1. 6. 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

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

    Författare :Per Persson; Kärnfysik; []
    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.

  4. 8. The effect of dissolved hydrogen on spent nuclear fuel corrosion

    Författare :Patrik Fors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; alpha-doped; Nuclear waste repository; Hydrogen; Solubility; Corrosion; UO2; MOX; Spent nuclear fuel; High burn-up; Groundwater;

    Sammanfattning : In case of a canister failure in a deep bedrock repository for nuclear fuel, the release of radiotoxic nuclides to the groundwater will depend on the chemical environment near the fuel surface.Due to the presence of large amounts of iron in the canister, hydrogen will be formed if the canister becomes groundwater flooded.

  7. 10. Nucleon-Induced Fission Cross Sections of Heavy Nuclei in the Intermediate Energy Region

    Författare :Alexander Prokofiev; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Fission; cross section; n; f reaction; p; intermediate energy; database; nuclear reaction; neutron; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

    Sammanfattning : Fission is the most important nuclear reaction for society at large today due to its use in energy production. However, this has raised the problem of how to treat the long-lived radioactive waste from nuclear reactors. LÄS MER
