  1. 1. Compilation and evaluation of validations of computer codes for spent nuclear fuel – a review

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Staffan Fors; [2019]
    Keywords : Nuclear fuel; Kärnbränsle; Slutförvar; Fissionsprodukter; Physics and Astronomy;

    Abstract : This report describes a systematic review regarding validations of calculations by measurements of isotopic compositions, or decay heat, on spent nuclear fuel, SNF. 15 relevant or otherwise interesting studies, were found. Two reports were chosen among the found studies and analyzed. READ MORE

  2. 2. The Victims at Sandby Borg : Tracing mobility and diet usingstrontium analyses

    University essay from Stockholms universitet/Arkeologiska forskningslaboratoriet

    Author : Kerstin Calleberg; [2019]
    Keywords : 87Sr 86Sr; strontium; migration; Sandby borg; Öland; massacre; teeth; Migration Period; Iron Age; Laser Ablation;

    Abstract : Sandby borg, an Iron Age ringfort on Öland, Sweden has been and is still at the center of attention in media and archaeological research. The massacre uncovered at the site during recent years opens many doors for analyses on the Migration Period (c. 400-550 AD) Iron Age skeletal remains. READ MORE

  3. 3. Rb-Sr sphalerite data and implications for the source and timing of Pb-Zn deposits at the Caledonian margin in Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Alfred Larsson; [2018]
    Keywords : Laisvall; Granberget; geochronology; sphalerite; ore; Rb-Sr; Earth and Environmental Sciences;

    Abstract : The eastern Caledonian erosional front hosts the world-class Pb-Zn deposit at Laisvall (64 Mt mined) and Granberget mineralization, northern Sweden, along with several other smaller, related types of deposits consisting of impregnation mineralization of galena and sphalerite in clastic host rocks. Previous work have discussed the nature of the ore-forming processes and constraints for the timing of the mineralization, however, the mechanisms are still not fully understood and previous age determinations are ambiguous.

  4. 4. Phase field modelling of LLZO/LCO cathode-electrolyte interfaces in solid state batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Michele Riva; [2018]
    Keywords : LLZO; LCO; phase; field; phase-field; phasefield; solid; state; solid-state; solidstate; battery; batteries; sintering; model; modelling;

    Abstract : This work describes two phase field models for the simulation of the interface evolution between a LiCoO2 cathode (LCO) and a Li7La3Zr2O12 solid electrolyte (LLZO) in a Li-metal/LLZO/LCO battery during high temperature sintering. In these conditions atomic species tend to diffuse into the opposing material, creating an intermediate layer of mixed composition which resists the movement of lithium ions. READ MORE
