1. 6. 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. 7. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Tanmmay Rout; [2023]
   Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

   Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

4. 8. Paths forward for Sustainable Maritime Transport : A techno-economic optimization framework for next generation vessels

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

   Author : Julian Ulrich Hausweiler; [2023]
   Keywords : ;

   Abstract : Recently, the decarbonization of maritime transport has received increased attention, in order to align with the targets of the Paris Agreement. In 2023, the International Maritime Organization unveiled their revised greenhouse gas strategy with an ambitious target: net-zero emissions by 2050. READ MORE

5. 9. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing

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

   Author : Therese Bäckström; [2023]
   Keywords : Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

   Abstract : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. READ MORE

6. 10. Parallel Operation of Grid-Forming Power Inverters

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

   Author : Alessia Camboni; [2023]
   Keywords : ;

   Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE
