  3. 2. 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

  4. 3. 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

  5. 4. 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.

  7. 5. Durability of Cementitious Materials in Long-Term Contact with Water

    Författare :Arezou Babaahmadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nuclear electricity is considered to be an alternative energy production solution for the power industry in many countries. To ensure the sustainability of this energy solution, the disposal of the produced waste is one of the biggest issues facing nuclear electricity industries. LÄS MER
