  1. 21. A Comparative Analysis of Decommissioning Scenarios Based on Radiation Dose Modeling and Multi-criteria Decision Analysis for Oskarshamn Nuclear Reactor 3 : Lessons Learned from Operating Experience in the Reuse of Decommissioned Sites

    Magister-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :May AlAli; [2020]
    Nyckelord :;

    Sammanfattning : An increasing number of decommissioning activities are being undertaken worldwide at facilities where radioactive material has been produced, used, or managed, which will also be the case of the Oskarshamn nuclear reactor O3 in Sweden, the remaining operational unit at that power plant. Decommissioning, which seems to be the sign of ending, is, in fact, a future-oriented process that can prove successful the safe management of nuclear facilities throughout their entire lifetimes but especially after shutdown.

  3. 22. Trendning och tillståndsövervakning av ventilmanöverdon i säkerhetssystem på Forsmark 1 och 2

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Egil Schultz; [2020]
    Nyckelord :;

    Sammanfattning : Nuclear power is one of the main players in the Swedish energy system with close to40% of the electricity production. As nuclear power needs to have a well- functioningsafety system for cooling the reactor and prevent contamination in case of anaccident, the components of this system must be maintained in a functioningcondition.

  4. 23. Emergency Power for Wind Turbine Yaw System - Project initialization tool

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

    Författare :Vigan Spahiu; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The Yaw Power Backup System (YPBS) is a safety system that needs to be incorporated in the Wind Power Plant (WPP) in order to provide emergency power during a power outage. The YPBS enables the Wind Turbine Generator (WTG) to perform a yawing operation in extreme weather conditions. LÄS MER

    Sammanfattning : This master thesis has been conducted at Forsmark nuclear power plant. In nuclear power plants, safety is one of the most important tasks. After the Fukushima-accident, Forsmarks Kraftgrupp AB investigated the possibility to have additional emergency cooling systems. LÄS MER

  7. 25. Enhancing Reaction System for Hydrolysis on Aluminum

    Master-uppsats, KTH/Kemiteknik

    Författare :Akhil Madem; [2019]
    Nyckelord :range extender; battery electric vehicle; hydrogen for automobiles; distansförlängare; eldrivet fordon; väte för bilar;

    Sammanfattning : A range extender in a battery electric vehicle supplements the existing drive system as an add-on module. Range extenders can comprise of any combination of conventional fuel, battery or fuel cell driven modules. The idea of a sub-system changes with the type of range extender. LÄS MER
