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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

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

    Sammanfattning : 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. LÄS MER

  2. 2. Investigation of a Biofilm Reactor Model with Suspended Biomass

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Alma Masic; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

    Sammanfattning : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. LÄS MER

  3. 3. Modeling, Control and Optimization of a Plate Reactor

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Staffan Haugwitz; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. LÄS MER

  4. 4. A trinity of sense Using biomass in the transport sector for climate change mitigation

    Detta är en avhandling från Stockholm : KTH

    Författare :Erik G. Lindfeldt; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofuel; biomass; carbon dioxide capture and storage; energy systems; ethanol; hybrid cycle; mixed conducting membrane reactor; pressurized fluidized bed combustion; Sweden; transport; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : This thesis analyses two strategies for decreasing anthropogenic carbon dioxide (CO2) emissions: to capture and store CO2, and to increase the use of biomass. First, two concepts for CO2 capture with low capture penalties are evaluated. LÄS MER

  5. 5. Response Matrix Reloaded for Monte Carlo Simulations in Reactor Physics

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Mickus Ignas; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kärnenergiteknik; Nuclear Engineering;

    Sammanfattning : This thesis investigates Monte Carlo methods applied to criticality and time-dependent problems in reactor physics. Due to their accuracy and flexibility, Monte Carlo methods are considered as a “gold standard” in reactor physics calculations. However, the benefits come at a significant computing cost. LÄS MER
