1. 6. The Nuclear Waters of the Soviet Union : Hydro-Engineering and Technocratic Culture in the Nuclear Industry

   Författare :Achim Klüppelberg; Per Högselius; Kati Lindström; Anna Storm; Melanie Arndt; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; Nuclear power; water; technocratic culture; USSR; energy system; hydro-nuclear entanglements; Atomkraft; Wasser; technokratische Kultur; Sowjetunion; Energiesystem; hydronukleare Verflechtungen; Kärnkraft; vatten; teknokratisk kultur; Sovjetunionen; energisystem; hydronukleära sammanflätningar; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

   Sammanfattning : After the development of nuclear weapons, civil applications were seen as a way through which protagonists of Soviet modernity could embrace a new future, which Josephson called atomic-powered communism. Where hydro-powered communism had reached its boundaries, nuclear energy was to take over. LÄS MER

3. 7. Studies of Long-lived Radionuclides in the Environment - with Emphasis on 99Tc, 237Np and Pu Isotopes

   Författare :Patric Lindahl; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; atomic ratio; environmental samples; nuclear weapons fallout; Chernobyl fallout; bioindicators; activated carbon; Sellafield; plutonium; neptunium; ICP-MS; technetium;

   Sammanfattning : Studies of the long-lived anthropogenic radionuclides 99Tc, 237Np, 239Pu and 240Pu were performed in marine and terrestrial areas contaminated by different accidental and controlled releases of radioactive materials. The three main sources discussed in this thesis are nuclear weapons tests, nuclear reprocessing plants and the Chernobyl accident. LÄS MER

4. 8. Nuclear Power as a Climate Change Mitigation Option: a Modelling Approach

   Författare :Mariliis Lehtveer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; sensitivity analysis; nuclear weapons proliferation; energy system model; nuclear power; climate change;

   Sammanfattning : Although nuclear power can provide electricity with very low life cycle carbon emissions and thus reduce the cost of climate change mitigation, it also brings along many specific challenges: accident risk, need for radioactive waste management and nuclear weapons proliferation risk. Due to this controversial nature nuclear power, among other energy forms, has been relatively little studied in a climate mitigation context. LÄS MER

5. 9. Nuclear safeguards directed to the application of multivariate analysis techniques to existing and future nuclear fuel cycles

   Författare :Vaibhav Mishra; Sophie Grape; Zsolt Elter; Erik Branger; Peter Dendooven; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear safeguards; nuclear fuel verification; spent fuel; molten salt reactors; machine learning.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

   Sammanfattning : For as long as nuclear power has existed, there has been a concern for effectively safeguarding nuclear material since it was learned that it could be misused. Early on, many nations were interested in nuclear power, and therefore there was an urgent need to verify that it was only used for civilian purposes. LÄS MER

7. 10. Physical Characterization of Actinide Particles - A Study on Novel Techniques for Radiological and Nuclear Safeguard Investigations

   Författare :Ylva Ranebo; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; plutonium oxide particles; secondary ion mass spectrometry; uranium oxide particles; hot particles; vibrating orifice aerosol generator; scanning electron microscopy; nuclear safeguards;

   Sammanfattning : This thesis presents a study of advanced analytical techniques, for the characterization of actinide particles originating from the non-peaceful use of nuclear technology and from international inspections of the nuclear fuel cycle associated with non-proliferation agreements. The thesis is based on five papers, which will be referred to by Paper I-V in the text. LÄS MER
