  1. 11. Learning by modeling energy systems

    Författare :Niclas Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; time slices; GIS; negative emissions; experience curves; BECCS; climate targets; reanalysis; variable renewables; open source; energy system models;

    Sammanfattning : Meeting the 2°C climate target would likely require reducing carbon dioxide emissions from the global energy system to virtually zero within 50-100 years, and within 30-50 years for the 1.5°C target. LÄS MER

  3. 12. Simulation and assessment of particle transport in fusion plasmas

    Författare :Emil Fransson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fusion -- Plasma physics -- Turbulent transport --Gyrofluid --Gyrokinetic;

    Sammanfattning : A civilized society need energy to function. An attractive new energy source is nuclear fusion with its abundance of fuel, intrinsic safety and limited environmental impact. Although the concept of fusion for energy has been well understood for over a century, to create it here on earth has been more irksome. LÄS MER

    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

  5. 14. Modelling the Role of Nuclear Power and Variable Renewables in Climate Change Mitigation

    Författare :Mariliis Lehtveer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy system model; nuclear power; multi-criteria analysis; variable renewables; climate change; optimisation;

    Sammanfattning : As the number of people on Earth and our energy needs have increased the system for providing this energy has become ever more complex and complicated and thus the need for more systematic understanding of it has grown. However, change in energy system is slow and many of the challenges that we face such as mitigating climate change need global solutions. LÄS MER

  7. 15. 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. LÄS MER
