1. 1. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Elin Bergroth; Greta Torstensson; [2023]
   Keywords : Solar Photovoltaic; National Guidelines; Fire Department; FE-analysis; TASEF; Solceller; Nationella Riktlinjer; Räddningstjänst; FE-analys; TASEF;

   Abstract : The global use of energy increases every day and to meet the growing demand, energy sources are constantly being developed to become more efficient and reliable. During the last decade, the global solar photovoltaics (PV) capacity has increased every year and in 2017, solar PV was the global leading power source of renewable energy. READ MORE

3. 2. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

   University essay from KTH/Materialvetenskap

   Author : Christopher Hallén; Marcus Johansson Storne; [2023]
   Keywords : ;

   Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

4. 3. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Wenhan Zhou; [2023]
   Keywords : Transuranus; AI; Nuclear Fuel Rods;

   Abstract : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. READ MORE

5. 4. Monitoring of Partial Discharges on Cable Terminations : An experimental approach to evaluate non-conventional online PD measurement techniques

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tony Sibo; [2023]
   Keywords : Monitoring; Partial discharges; Medium-voltage cable terminations; Sensor performance; Reliability evaluation; Infrared camera IR-camera ; Ultrasonic emission sensor AE-sensor ; Temperature and relative humidity sensor TRH-sensor ; High frequency current transformer HFCT ; Transient earth voltage antenna TEV-antenna ; Conventional VS non-conventional PD measurement techniques; Övervakning; Partiella urladdningar; Mellanspänningskabelslut; Evaluering av sensorprestanda; Utvärdering av systemets tillförlitlighet; Infraröd kamera; Ultraljudssensor; Temperatur- och relativ fuktighetssensor; Högfrekvent strömtransformator; Transient jordspänningsantenn; Konventionella vs icke-konventionella mättekniker;

   Abstract : The transmission of electric power over long distances has historically posed challenges. However, the advent of high-voltage engineering has not only addressed distance barriers and power losses in electricity transmission and distribution, but it has also significantly improved the efficiency and transmission capacity of power grids.
