  1. 1. Impact of material migration on plasma-facing components in tokamaks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Alvaro Garcia Carrasco; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fusion; material migration; wall conditioning; diagnostic mirrors; plasma-facing materials; Physics; Fysik;

    Abstract : Plasma-wall interaction plays an essential role in the performance and safety of a fusion reactor. This thesis focuses on the impact of material migration on plasma-facing components. It is based on experiments performed in tokamaks: JET, TEXTOR and ASDEX Upgrade. READ MORE

  2. 2. Material migration in tokamaks: Studies of deposition processes and characterisation of dust particles

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Armin Weckmann; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tokamak; fusion; plasma; material migration; particle transport; TEXTOR; PWI; plasma-wall interaction; plasma facing components; PFC; PFM; plasma facing materials; ALT limiter; MoF6; tracer experiment; molybdenum hexafluoride; future energy source; fuel retention; deuterium retention;

    Abstract : Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. READ MORE

  3. 3. Material characterization for magnetically confined fusion Surface analysis and method development

    University dissertation from KTH Royal Institute of Technology

    Author : Petter Ström; KTH.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The dream of abundant clean energy has brought scientists and laypeople alike to ponder the possibilities of nuclear fusion since it was established as the energy source of the stars in 1939. Starting from the mid the 20th century, significant effort has been put into overcoming the technological challenges related to the construction of a power plant, but initial optimism has faded somewhat due to a notable absence of practical outcomes.

  4. 4. Coil Design and Related Studies for the Fusion-Fission Reactor Concept SFLM Hybrid

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Hagnestål; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fusion; Fission; Hybrid reactor; Actinides; Mirror Machine; Quadrupolar mirror; Coils; Fysik; Physics;

    Abstract : A fusion-fission (hybrid) reactor is a combination of a fusion device and a subcritical fission reactor, where the fusion device acts as a neutron source and the power is mainly produced in the fission core. Hybrid reactors may be suitable for transmutation of transuranic isotopes in the spent nuclear fuel, due to the safety margin on criticality imposed by the subcritical fission core. READ MORE

  5. 5. Plasma-Facing Components in Tokamaks Material Modification and Fuel Retention

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Darya Ivanova; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic confinement fusion; plasma-facing components; plasma-facing materials; fuel inventory; erosion and deposition;

    Abstract : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for the steady-state operation of a fusion reactor, e.g. ITER. READ MORE
