1. 1. Återbruk kontra återvinning av litiumjonbatterier

   Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Marija Lucija Pajtlar; Elin Söderlund; [2023]
   Nyckelord :Lithium ion batteries; battery recycling; second-life battery applications; circularity; battery storage system; Litiumjonbatterier; batteriåtervinning; batteriåterbruk; cirkularitet; batterilagersystem;

   Sammanfattning : I Sverige läggs stort fokus på omställningen till ett hållbart och klimatneutralt samhälle, där avkarbonisering och elektrifiering av transportsektorn anses avgörande för att minska utsläpp av växthusgaser. En storskalig batteriproduktion i Sverige och i Europa medför nya problem kring hållbarhetsaspekter gällande utvinning av råvara som exempelvis litium, kobolt och nickel. LÄS MER

3. 2. 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 kärnfysik

   Författare :Martin Nilsson Lind; [2023]
   Nyckelord :fission; zircaloy; corrosion; radiolysis; radiation; BWR; Monte Carlo; GEANT4; lwrChem;

   Sammanfattning : 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

4. 3. Potential benefits of implementing demand response into Vattenfall’s district cooling grid in Uppsala, Sweden

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Magdalena Guerrero Wretljung; [2023]
   Nyckelord :;

   Sammanfattning : Lately, there has been an increased cooling demand in Vattenfall’s district cooling (DC) network in Uppsala, Sweden. This especially occurs on warmer summer days, during so-called peak demand periods, where there is limited cooling capacity combined with limited distribution capacity in the network. LÄS MER

5. 4. System impact of micro-production

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Annie Haraldsson; [2023]
   Nyckelord :Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

   Sammanfattning : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG. LÄS MER

7. 5. Evaluating the Ownership of Personal data in the Cloud by Optimizing the IT Architecture : Applying a reference architecture to make the ownership of personal data more clear within an organization

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

   Författare :Tilda Myrsell; Sofie Hulteberg; [2023]
   Nyckelord :Cloud computing; reference architecture; personal data; international standard ISO IEC 17789; data security; data ownership;

   Sammanfattning : ​​Cloud computing is an area that many companies use in order to stay in line with technological development. To keep these systems productive and easily managed, a reference architecture can be used as a framework and also as a manual on how to structure an organization to suit its specific needs and goals.
