1. Development of a computational method for determining gamma energy escape from calorimeters at CLAB
University essay from Uppsala universitet/Tillämpad kärnfysikAbstract : Swedish Nuclear Fuel and Waste Management Company- SKB has conducted measurement campaigns at the Swedish central interim storage facility for spent nuclear fuel- CLAB over the years, extending from year 2003 to 2019 where the gamma energy escape was acquired. At CLAB the spent nuclear fuel assembly is inserted into the calorimeter; device intended to measure temperature increase due to decay heat from the fuel assembly. READ MORE

2. Theoretical design of an XRF system for environmental measurements of Mercury in fiber banks
University essay from Mittuniversitetet/Institutionen för elektronikkonstruktionAbstract : This thesis demonstrates the advantages of using the Energy-dispersive X-ray fluorescence (ED-XRF) system to quantify the mercury content in fiber banks at first. The Monte Carlo N-Particle (MCNP) code was then used to simulate the XRF system model with suitable parameters such as the input X-ray energy level, the detector material, and the environmental factor (water depth).

3. Simulations of a back scatter time of flight neutron spectrometer for the purpose of concept testing at the NESSA facility.
University essay from Uppsala universitet/Tillämpad kärnfysikAbstract : A back scatter time of flight neutron spectrometer consisting of two scintillation detectors is simulated in Geant4 to examine whether it is possible to perform a proof of concept test at the NESSA facility at Uppsala University. An efficiency of ε = 2.45 · 10^-6 is shown to be large enough for a neutron generator intensity of 1. READ MORE

4. Monte Carlo modelling of an X-ray fluorescence detection system by the MCNP code
University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktionAbstract : This survey has shown, using the Monte Carlo N-Particle(MCNP) code to model a detection system, to demonstrate that it is possible to design a system to measure hazard elements in polluted water. At first, the measurement method needs to be determined. READ MORE

5. Simulation of neutron generator assisted gamma emission tomography for inspection of fissile content in spent nuclear fuel
University essay from Uppsala universitet/Tillämpad kärnfysikAbstract : 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
