1. 1. Reactor Chemistry in LWR SMRs : Determination of the rate constant for the reaction between boric acid and hydroxyl radicals

   University essay from KTH/Tillämpad fysikalisk kemi

   Author : Fredrik Petersson; [2023]
   Keywords : LWR; SMR; Water chemistry; Radiolysis; Boric acid; LWR; SMR; vattenkemi; Radiolys; Borsyra; Hydroxylradikal;

   Abstract : Ett problem vid byggandet av nya kärnkraftverk för elproduktion är de stora investeringskostnaderna samt den långa tiden det att få tillstånd för en reaktor och bygga den. Nyligen färdigställdes den tredje reaktorn vid Olkiluoto I Finland, den tog 18 år att färdigställa exklusive tiden att få tillstånd för reaktorn. READ MORE

3. 2. Wind Turbine Recovery Forecasting using Survival Analysis

   University essay from Lunds universitet/Matematisk statistik

   Author : Anton Palets; [2023]
   Keywords : Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

   Abstract : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

4. 3. Dam Failure Analysis of the Parteboda Hydropower Plant : A deterministic approach

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Magnus Simon Graf; [2023]
   Keywords : ;

   Abstract : Despite all the benefits a dam can provide, hundreds of years of experience have shown the destructive forces that can be unleashed by dam failure. To carry out risk management and execute mitigative measures for a dam facility, it is first necessary to assess the incremental consequences of a potential dam failure. READ MORE

5. 4. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Rosalie Johnsson; Lilian Asiegbu; [2022]
   Keywords : gas turbine; turbine inlet guide vane; film-cool; film cool; Computational Fluid Dynamics; CFD; heat transfer coefficient; Shear Stress Transport k-ω; SST k-ω; Scale Resolving Hybrid; SRH; turbulence modelling;

   Abstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE

6. 5. Optimization of sprue design for advanced investment casting through FEA analysis

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Kanthee Prathan; [2020]
   Keywords : Design; FEM; FEA; Investment casting; Sprue design;

   Abstract : Investment casting is a complex manufacturing method with many challenges that must be solved before components of the right quality can be produced. TPC is a company that utilizes investment casting to produce a variety of products, lately the company has higher ambition in wanting to cast higher technical demanding component like heat resistant gas turbine blades.
