  1. 1. Propagation of Nuclear Data Uncertainties for Reactor Physics Parameters in Fluorine-19-based Molten Salt Reactors

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Sigfrid Stjärnholm; [2023]
    Keywords : ;

    Abstract : It could be argued that a renaissance is taking place for the global interest in nuclear power - especially for the development of the next generation of reactor systems that aim at solving the problems with contemporary energy production with nuclear technology. One such proposed concept for Gen IV nuclear power is a Molten Salt Reactor (MSR), in which the nuclear fuel is in solution of a salt - often based on fluorine or chlorine. READ MORE

  2. 2. Comparative study of green infrastructure valuation toolkits B£ST and GI-VAL : Increase comprehensiveness of economic green infrastructure valuation assessments

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ludvig Callermo Riedel; [2022]
    Keywords : Green infrastructure; Ecosystem services; Green infrastructure valuation; Economic valuation; Green infrastructure assessment tool; Sustainable urban development;

    Abstract : There is an abundance of ready-made tools for assessing the economic value of green infrastructure. Each with more or less unique design components and method approaches concerning quantifying and monetizing green infrastructure. READ MORE

  3. 3. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  4. 4. An analysis of the understanding of maintenance of nature-based solutions for urban stormwater management

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emma Knapik; [2022]
    Keywords : Flood adaptation; resilience; sustainability; green infrastructure; uncertainty; Översvämnings anpassning; spänstighet; hållbarhet; osäkerhet;

    Abstract : Urban stormwater management is necessary to protect human life and society from the dangers and damages associated with flooding from extreme weather events. Conventional measures of stormwater management utilise grey infrastructure to convey runoff away from urban areas, but due to increasing urbanization, aging of urban infrastructure, climatic variability, and flooding due to extreme weather events, these measures are often no longer sufficient.

  5. 5. Groundwater Inflow into Fractured Rock Tunnels

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mariam Beydoun; [2022]
    Keywords : groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

    Abstract : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. READ MORE
