1. 1. Improved Modelling For Oxidation Of Zircalloy Fuel Cladding Tubes In PWRs

   Master-uppsats, KTH/Fysik

   Författare :Rafaël Bellachia; [2023]
   Nyckelord :Nuclear Engineering; Corrosion; Zircalloy; PWR; Nuclear Fuel; Kärnteknik; Korrosion; Zircalloy; PWR; Kärnbränsle;

   Sammanfattning : The fuel cladding is an essential component in the defence-in-depth strategy for nuclear safety. Its integrity and durability are therefore critical for maintaining acceptable safety conditions. However, the integrity of the cladding can be compromised during normal operation due to corrosion and hydriding. 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. Effektivisering av klimatberäkningar för ombyggnadsprojekt : För projekt under 50 MSEK hos Akademiska hus

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljö

   Författare :Elsa Rudqvist; Ominder Bhogal; [2023]
   Nyckelord :effektivisering; schablonvärden; klimatberäkning; koldioxidekvivalenter; livscykelanalys; ombyggnadsprojekt.;

   Sammanfattning : The construction industry is currently responsible for a large amount of greenhouse gas emissions that contribute to the enhanced greenhouse effect. In hopes of facilizing a sustainable development, a new law came in force 2022 requiring climate declarations for new construction projects. LÄS MER

5. 4. Life cycle analysis of retrofit solutions for brake emission

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

   Författare :Panagiotis Kampouridis; [2023]
   Nyckelord :Non-exhaust emissions; Retrofit solutions; Brake emission; streamline LCA; Life cycle assessment; Brake system; Particulate emission; Particulate matter; PM; Laser cladded; Filtration; Statistical desirability function; Icke-avgasutsläpp; Eftermonteringslösningar; Bromsemission; LCA; Livscykelanalys; Bromssystem; Partikelemission; PM; Laserklädd; Filtrering; Statistisk önskvärdhetsfunktion;

   Sammanfattning : This Master Thesis project is focused on Life Cycle Analysis (LCA) of retrofit solutions for brake emission and the comparison of each solution. Background research was performed to check possible solutions to the Particulate Matter (PM) problem that non-exhaust emissions contribute to. LÄS MER

7. 5. III-V semiconductor waveguides for application in nonlinear optics.

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Andreas Charalampous; [2022]
   Nyckelord :InGaP; optical waveguides; integrated optics; quantum nonlinear optics; SHG; SPDC; InGaP; optiska vågledare; integrerad optik; icke-linjär kvantoptik; SHG; SPDC;

   Sammanfattning : This thesis presents studies on III-V semiconductor waveguides with particular emphasis on second-order optical nonlinearity. The nonlinear processes that were investigated in this thesis are the Second Harmonic Generation (SHG) and the Spontaneous Parametric Down-Conversion (SPDC). LÄS MER
