11. Assessment of How Design and Operational Parameters Affect Plutonium Production for Pressurized Heavy Water Reactors : A Study of the Ågesta, NRX and CANDU Reactors
Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : Nuclear weapons are an ever-present danger which threatens our very existence, which is whymany call for total nuclear disarmament. To do this, we need to know how many nuclear bombsthere are in the world. LÄS MER
12. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems
Kandidat-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskapSammanfattning : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. LÄS MER
13. Numerical Estimation of Critical Exponents in the 3D XY Model
Master-uppsats, KTH/FysikSammanfattning : The experimentally obtained value of the critical exponent ν is presently in significant disagreement with current theoretical predictions for the λ-universality class. We suggest two novel approaches of determining the exponents ν and η by utilizing the effects of finite size scaling. LÄS MER
14. Total Monte Carlo of the fission model in GEF and its influence on the nuclear evaporation in TALYS
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysikSammanfattning : Features recently added to the nuclear reaction software TALYS allow the use of the GEF model as a fission fragment generator. GEF generates data for fission fragment yields, total excitation energy (TXE), total kinetic energy (TKE) and individual fragment excitation energies (E*) with their standard deviations through Monte Carlo simulations for TALYS.

15. 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 kärnfysikSammanfattning : 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
