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

    Författare :Darya Ivanova; Marek Rubel; Bernard Pégourié; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic confinement fusion; plasma-facing components; plasma-facing materials; fuel inventory; erosion and deposition;

    Sammanfattning : 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. LÄS MER

  3. 2. Multi-echelon Inventory Control with Integrated Shipment Decisions

    Författare :Olof Stenius; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inventory; Multi-echelon; Stochastic; Shipment consolidation; Delivery decisions;

    Sammanfattning : Rising fuel prices and increasing environmental awareness emphasizes the importance of the transportation aspect in logistics. This calls for new improved inventory control methods that consider the effects of shipment strategies in a more realistic manner. LÄS MER

  4. 3. Air Pollution from Ships - Emission Measurements and Impact Assessments

    Författare :Hulda Winnes; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

    Sammanfattning : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. LÄS MER

  5. 4. Fuel retention and fuel removal from first wall components in tokamaks

    Författare :Darya Ivanova; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik;

    Sammanfattning : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for a steady-state operation of a fusion reactor, e.g. ITER. These topics have been explored in the on-going Ph. LÄS MER

  7. 5. Modeling Aspects of Chemical-Looping Combustion for Solid Fuels

    Författare :Pontus Markström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold-flow model; Residence time; Chemical-looping combustion; Solid fuel; Scaling;

    Sammanfattning : Chemical-looping combustion is a novel technology for combustion of fossil fuel. By using a circulating bed material to transfer oxygen to the fuel, a pure stream of carbon dioxide can be obtained from the flue gas, undiluted by nitrogen. LÄS MER
