  1. 1. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Sofia Bjarheim; [2024]
    Nyckelord :Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

    Sammanfattning : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. LÄS MER

  3. 2. Studying Elliptic Flow in High Centrality Pb-Pb Collisions using Proton Collision Background Fitting

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Philip Fredholm; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this report, the elliptic flow in high centrality Pb-Pb collisions is calculated using two particle correlations $v_2\{2\}$ but without any imposed separation in η with data taken from the ALICE experiment at CERN in 2015. Instead, measurements of the same correlations in proton-proton collisions is used as a background to account for non-flow effects and data is correlated between the time projection chamber and the forward multiplicity detectors in order to avoid intra-jet correlations.

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

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

    Författare :Staffan Fors; [2019]
    Nyckelord :Nuclear fuel; Kärnbränsle; Slutförvar; Fissionsprodukter; Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

  5. 4. Cs-137 i Svamp : Dataanalysrutiner för gammaspektroskopi

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :David Nordman; [2018]
    Nyckelord :gamma; spectroscopy; mushroom; radioactivity; efficiency; gammaspektroskopi; dataanalys; radioaktivitet; svamp; chernobyl; effektivitet;

    Sammanfattning : Kärnkraftsolyckan i Tjernobyl ledde till en spridning av radioaktiva ämnen över Europa och Sverige. År 2018 är det 32 år sedan kärnkraftsolyckan ägde rum och den enda radioaktiva isotopen som finns kvar i det svenska ekosystemet som följd av olyckan i en betydande mängd är Cs-137, på grund av dess 30-åriga halveringstid.

  7. 5. The Characteristics of B4C Coated Scintillators

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

    Författare :Anton Bodahl; [2016]
    Nyckelord :B4C; Scintillators; Coincidence Measurements; LIBAF; Homogenity Measurements; Physics and Astronomy;

    Sammanfattning : The characteristics of Boron Carbide (B4C) coated polyvinyltoluene scintillators with a sputtered B4C coating ranging between 200 and 1000 nm have been studied using a photomultiplier - Lanthanum Bromide detector setup with a PuBe neutron source. The raw data from the detectors was analysed by imposing a detector coincidence condition. LÄS MER
