1. 1. Improved Modelling For Oxidation Of Zircalloy Fuel Cladding Tubes In PWRs

   Master-uppsats, KTH/Fysik

   Författare :Rafaël Bellachia; [2023]
   Nyckelord :Nuclear Engineering; Corrosion; Zircalloy; PWR; Nuclear Fuel; Kärnteknik; Korrosion; Zircalloy; PWR; Kärnbränsle;

   Sammanfattning : The fuel cladding is an essential component in the defence-in-depth strategy for nuclear safety. Its integrity and durability are therefore critical for maintaining acceptable safety conditions. However, the integrity of the cladding can be compromised during normal operation due to corrosion and hydriding. LÄS MER

3. 2. Characterization of neutron detection efficiency in a liquid organic scintillator

   Kandidat-uppsats,

   Författare :Ebba Wargh; Nadine Tabeshnia; [2023]
   Nyckelord :;

   Sammanfattning : Neutron detectors in the form of liquid organic scintillators are widely used for nuclear disarmament purposes. The main purpose of this thesis is to characterize the neutron detection efficiency of the organic liquid scintillator EJ-309 using Monte Carlo based simulations in the simulation program Geant4.

4. 3. Pre-study for SMR and Nuclear Establishment in Norway

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Johan Stefan Nordström; [2023]
   Nyckelord :Energy mapping; Nuclear power; SMR; small modular reactors; siting; Norway; Energy; Technology and Engineering;

   Sammanfattning : Norway has Europe’s highest share of renewable electricity production and the lowest power sector emissions. Thanks to the country’s stable power production, Norway has affordable and stable access to electricity, leading to industries choosing to relocate to the country. LÄS MER

5. 4. High spatial resolution study of local corrosion effects on BWR-fuel cladding : Using a combined method of GEANT4 and lwrChem

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

   Författare :Martin Nilsson Lind; [2023]
   Nyckelord :fission; zircaloy; corrosion; radiolysis; radiation; BWR; Monte Carlo; GEANT4; lwrChem;

   Sammanfattning : The core of a BWR constitutes a highly complex radiational and chemical environment. Nuclear fission is utilized to generate power and as a consequence, large quantities of ionizing radiation are produced. Gamma and beta-particles along with neutrons have the sufficient ranges to escape the fuel rods and deposit energy in the reactor coolant. LÄS MER

7. 5. Uncertainty Analysis : Severe Accident Scenario at a Nordic Nuclear Power Plant

   Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Josefin Hedly; Mikaela De Young; [2023]
   Nyckelord :Nuclear power plant; microdata analysis; Random Forest; k-Nearest Neighbor; SVM;

   Sammanfattning : Nuclear Power Plants (NPP) undergo fault and sensitivity analysis with scenario modelling to predict catastrophic events, specifically releases of Cesium 137 (Cs-137). The purpose of this thesis is to find which of 108 input-features from Modular Accident Analysis Program (MAAP)simulation code are important, when there is large release of Cs-137 emissions. LÄS MER
