1. 6. A Monte Carlo simulation study of collimators for a high-spatial-resolution Gamma Emission Tomography instrument

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Anastasios Anastasiadis; [2019]
   Keywords : ;

   Abstract : The present master thesis concerns a study of collimator designs for a high-spatial-resolution Gamma Emission Tomography (GET) instrument for used fuels utilizing Monte Carlo simulation codes. Designing a collimator for this purpose is a multilateral process that requires many interconnected and conflicting objectives to be taken into consideration. READ MORE

3. 7. Ekologisk kompensation: en utvärdering av åtgärder för gölgroda (Pelophylax lessonae) i Forsmark

   University essay from SLU/Dept. of Ecology

   Author : Malin Karlsson; [2018]
   Keywords : ekologisk kompensation; gölgroda; Pelophylax lessonae; Rana lessonae; metapopulation; damm;

   Abstract : Exploatering av värdefulla naturområden kan kompenseras genom s.k. ekologisk kompensation. Ekologisk kompensation har hittills sällan tillämpats och därför saknas ofta uppföljning av dessa. READ MORE

4. 8. Radiation Effects on KBS-3 Barriers: SKB’s work so far

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Ismael Safi; [2017]
   Keywords : KBS-3; Repository; Radiation; Bentonite; Montmorillonite;

   Abstract : In the Swedish concept for final disposal of spent nuclear fuel, referred to as KBS-3, a three-layered protection system is used. The system consists of a copper canister holding the spent nuclear fuel deposited 500 meters in a repository built in groundwater saturated granitic rock. READ MORE

5. 9. Simulation of neutron generator assisted gamma emission tomography for inspection of fissile content in spent nuclear fuel

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Erik Wickman; [2017]
   Keywords : ;

   Abstract : This is a feasibility study of a new measurement technique for spent nuclear fuel. The technique combines gamma emission tomography with neutron activation analysis. The idea is to measure high-energy characteristic gamma from short-lived fission products and thereby verify the fissile material content in spent nuclear fuel assemblies. READ MORE

6. 10. 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
