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

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Sigfrid Stjärnholm; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  3. 2. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

    Författare :Tim Günter; [2022]
    Nyckelord :ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

    Sammanfattning : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. LÄS MER

  4. 3. Calculation of neutron scattering libraries for liquid ortho-deuterium and hydrogen deuteride

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Alexander Huusko; [2022]
    Nyckelord :PIMD; NJOY; HD; D2; HighNESS; ESS; RPMD; TSL; Physics and Astronomy;

    Sammanfattning : The European Spallation Source (ESS) has launched a project called HighNESS, with the task of investigating the potential of adding a second moderator system to the facility, with ortho-deuterium (o-D2) being the main material of interest. Another moderator material which could be of interest is hydrogen deuteride (HD). LÄS MER

  5. 4. Scattering Kernel Calculations for Liquid Para-Hydrogen Using Ring Polymer Molecular Dynamics

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Pontus Nordin; [2020]
    Nyckelord :Neutron scattering; Para-hydrogen; Scattering kernels; Molecular dynamics; Ring polymer molecular dynamics; ESS; Physics and Astronomy;

    Sammanfattning : The European Spallation Source will be a world leading neutron source available for a range of neutron scattering experiments in the scientific community. In order to accurately simulate the production of cold and thermal neutrons, an accurate calculation of the neutron cross section for the moderator materials is needed. LÄS MER

  7. 5. Input Format Design and Translator Development for NJOY

    Kandidat-uppsats, Institutionen för informationsteknologi

    Författare :Emil Hessman; [2011]
    Nyckelord :;

    Sammanfattning : The NJOY Nuclear Data Processing System is a software system used for nuclear data management [1]. In particular, it is used to convert evaluated nuclear data for materials stored in Evaluated Nuclear Data Files (ENDF) [2] into different formats, as well as performing operations on the data.
