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

   University essay from KTH/Fysik

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

   Abstract : 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. READ MORE

3. 2. High spatial resolution study of local corrosion effects on BWR-fuel cladding : Using a combined method of GEANT4 and lwrChem

   University essay from Uppsala universitet/Tillämpad kärnfysik

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

   Abstract : 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. READ MORE

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

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Panagiotis Kampouridis; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

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

   University essay from KTH/Tillämpad fysik

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

   Abstract : 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). READ MORE

6. 5. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Matilda Tiberg; [2022]
   Keywords : Pressurized Water Reactor; Safetey analysis; LOCA; Intermediate Break; PKL; TRACE; transient; thermal hydraulics;

   Abstract : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. READ MORE
