1. 6. Uranium Mineralizations at Kiirunavaara,Northernmost Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Diego Segovia Menard; [2022]
   Keywords : kiirunavaara; uranium; EPMA; water; hydrothermal;

   Abstract : In recent years, a variably high amount of uranium (U) and radon (Rn) were found in the water and airof the Kiirunavaara mine in Kiruna, northern Sweden. The Swedish Agency for Marine and WaterManagement (Havs och vattenmyndigheten) has maximum limits for “special polluting substances” inwater that is released to natural recipients (HVMFS 2019:25), therefore, the mining company LKAB,owner and operator of the Kiirunavaara mine, decided to conduct a study to investigate the issueregarding these findings, triggering this master thesis.

6. 10. Uncertainty & Sensitivity Analysis of Nuclear Fuel Using Transuranus & Dakota

   University essay from KTH/Fysik

   Author : Udyanth Vaidya; [2021]
   Keywords : Nuclear; Nuclear Energy; SUNRISE; Transuranus; Dakota; LFR; Lead cooled fast reactor; Simulations; modelling; fuel performance code;

   Abstract : With the initiative taken by the SUNRISE project (Sustainable Nuclear Energy Research in Sweden) to construct a Lead-cooled research reactor, this thesis intends to extend the knowledge within nuclear fuel development. By using integral iterative modelling and simulating techniques that mimic real-world phenomena, novel fuel materials like uranium nitride are assessed for future validation. READ MORE
