1. 1. 2D Neutron Imaging with 10B-Based Multi-Blade Detector

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

   Author : Tõnu Ilves; [2018]
   Keywords : thermal; neutron; imaging; 2D; Multi-Blade; detector; boron; boron-10; nuclear physics; multi wire proportional chamber; digitizer; ESS; European Spallation Source; surface study; reflectometry; Physics and Astronomy;

   Abstract : In the field of thermal-neutron imaging, the Multi-Blade detector concept and design, being developed for the upcoming European Spallation Source in Lund, Sweden, is unique. The current report presents, for the first time, the neutron-imaging capabilities of a boron-10-based Multi-Blade thermal-neutron detector, measured at a reflectometry instrument at Rutherford Appleton Laboratory in Oxfordshire, England under high spallation neutron flux.

3. 2. Development of a Detector System for Detection of Thermal Neutrons from Spent Nuclear Fuel

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

   Author : Daniel Söderström; [2016]
   Keywords : neutron detection; neutron; 10B; boron-10; nuclear physics; boron; neutron detector; scintillator; boron carbide; B4C; nuclear fuel; repository; SKB; Physics and Astronomy; Technology and Engineering;

   Abstract : The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. READ MORE

4. 3. The Characteristics of B4C Coated Scintillators

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

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

   Abstract : 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. READ MORE

5. 4. Detailed B-10 depletion in control rods operatingin a Nuclear Boiling Water Reactor

   University essay from Institutionen för materialkemi

   Author : John Johnsson; [2011]
   Keywords : Boron depletion; control rod; Boiling Water Reactor; BWR;

   Abstract : In a nuclear power plant, control rods play a central role to control the reactivity ofthe core. In an inspection campaign of three control rods (CR 99) operated in theKKL reactor in Leibstadt, Switzerland, during 6 respectively 7 consecutive cycles,defects were detected in the top part of the control rods due to swelling caused bydepletion of the neutron-absorbing 10B isotope (Boron-10).
