1. 6. Modeling of a Hydraulic Rock Drill for Condition Monitoring

   University essay from Linköpings universitet/Fordonssystem

   Author : Adam Kagebeck; Mahdi Najafi; [2022]
   Keywords : Condition Monitoring System; Hydraulic Rock Drill; Diagnostic; Modeling; State Space Model;

   Abstract : This thesis aims to investigate the possibility of using a mathematical model to detect several common faults in a hydraulic rock drill. To this end, a parameterized state space model of the hydraulic drill, which simulate its behavior, is created. READ MORE

3. 7. Modelling of liquid leakage with ASTEC in a severe accident of a PWR

   University essay from KTH/Fysik

   Author : Thomas Begey; [2022]
   Keywords : Nuclear Physics; Modelling; Iodine Chemstry; Nuclear Safety; Kärnfysik; modellering; jodkemi; kärnsäkerhet;

   Abstract : In a nuclear reactor, in case of a severe accident occurs, backup circuits are usedlike SIS and CSS, flooding the reactor with water. This might lead to many liquidleakages outside the reactor containment building. READ MORE

5. 9. 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.
