  2. 16. Insights from modeling renewable electricity systems and developing hydropower models

    Author : Hanna Ek Fälth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewables; electricity systems; hydropower; nuclear; modeling; Europe; MENA; transmission; available land;

    Abstract : One strategy for reaching a carbon-neutral electricity system is a large-scale deployment of wind and solar power. However, electricity systems with high shares of wind and solar power rely on other technologies, e.g. READ MORE

  4. 17. Development of a Methodology for Detecting Coolant Void in Lead-cooled Fast Reactors by Means of Neutron Measurements

    Author : Peter Wolniewicz; Håkansson Ane; Christian Jammes; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LFR; fission chamber; nuclear; reactor; leak; criticality;

    Abstract : In a lead-cooled fast reactor (LFR), small bubbles (in the order of one mm or less) may enter the coolant from a leaking steam generator. If such a leakage is undetected the small bubbles may eventually coalesce into a larger bubble in local stagnation zones under the active core.

  5. 18. Mechanistic Modeling of Wall-Fluid Thermal Interactions for Innovative Nuclear Systems

    Author : Roman Thiele; Henryk Anglart; Xu Cheng; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GEN-IV reactors; Wall heat transfer; Computational Fluid Dynamics; Wall functions; Reactor design; Supercritical water; Liquid metal; Energy Technology; Energiteknik; Fysik; Physics;

    Abstract : Next generation nuclear power plants (GEN-IV) will be capable of not only producing energy in a reliable, safe and sustainable way, but they will also be capable of reducing the amount of nuclear waste, which has been accumulated over the lifetime of current-generation nuclear power plants, through transmutation. Due to the use of new and different coolants, existing computational tools need to be tested, further developed and improved in order to thermal-hydraulically design these power plants. READ MORE

  6. 19. Nucleon-Induced Fission Cross Sections of Heavy Nuclei in the Intermediate Energy Region

    Author : Alexander Prokofiev; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 20. Anti-nuclear Movements in Discursive and Political Contexts​ : Between Expert Voices and Local Protests

    Author : Ekaterina Tarasova; Mai-Brith Schartau; Björn Hassler; Marta Reuter; Södertörns högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social movements; nuclear energy; discourse; action repertoires; protests; Nuclear Renaissance; Russia; Poland; Sweden; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Energy policies which maintain and extend nuclear energy are often opposed by anti-nuclear movements. Ambitious plans for developing nuclear energy in Russia, constructing a first nuclear plant in Poland, and lifting the ban on nuclear energy while allowing the replacement of old reactors in Sweden are examples of such energy policies.
