  1. 1. Balancing Supply and Demand in an Electricity System - the Case of Sweden

    Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Oskar Mared; Victor Persson; [2018]
    Nyckelord :Electricity System; Intermittent Energy Sources; Balancing Supply and Demand; Frequency Control; Local Balancing Efforts; Socio-Technical Approach; Multi-Level Perspective; elsystem; intermittenta energikällor; balansera produktion och konsumtion; frekvensreglering; balansering på lokal nivå; socio-teknisk ansats; flernivåsansats;

    Sammanfattning : In an electrical system there needs to be a constant balance between supply and demand ofelectricity and this is measured by the frequency in the grid. Due to the increasing awarenessof climate change, more renewable energy resources have been introduced in the Swedishelectricity system. LÄS MER

  3. 2. Structural mechanics and resistance of concrete structures in the event of a hydrogen explosion in nuclear powerplants

    Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Victor Bjälke; [2018]
    Nyckelord :Fire engineer; structural mechanics; nuclear powerplants; hydrogen explosion; finite element method;

    Sammanfattning : This thesis deals with the problem of hydrogen explosions in nuclear power plants, and evaluates if the reactor hall is to be seen as a safety barrier for such events. Today, the reactor hall is not seen as a safety barrier that is able to withstand an internal explosion. LÄS MER

  4. 3. Numerical Simulation of Compressible Multicomponent Flows

    M1-uppsats, KTH/Mekanik

    Författare :Anthony Bourbi; [2015]
    Nyckelord :;

    Sammanfattning : France is a country where the sector of energy has a big importance. Seven out of the fourteen companies of the CAC40 (a french stock market index of the 40 biggest companies) are strongly involved in the energy sector: Total, GDF Suez, EDF, Legrand, Schneider Electric, Alstom, and Technip. This industry was also responsible for 1. LÄS MER

  5. 4. Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys

    Uppsats för yrkesexamina på avancerad nivå, Matematisk statistik

    Författare :Gustaf Klinga; [2013]
    Nyckelord :kärnkraft; extremvärdesteori; översvämning; översvämningsnivå; DBFL;

    Sammanfattning : This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites. Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events.

  7. 5. Thermal-hydraulic modelling of Forsmark 1 NPP in TRACE : Validation versus the 25th of July, 2006 plant transient

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för fysik och astronomi

    Författare :Lisa Bladh; [2010]
    Nyckelord :trace; modelling; Forsmark;

    Sammanfattning : There is a widespread use of thermal hydraulic codes in nuclear industry. The codesare used to analyse the transient and steady-state behavior of the nuclear powerplants. LÄS MER
