    Sammanfattning : The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and 60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy, and thereby connected it to utopian ideas about an eternal supply of energy. LÄS MER

  2. 2. Climatic conditions inside nuclear reactor containments : Evaluation of moisture condition in the concrete within reactor containments and interaction with the ambient compartments

    Författare :Mikael OXFALL; Avdelningen för Byggnadsmaterial; []
    Nyckelord :kärnkraft; betong; in situ mätningar; relativ fuktighet; kokvattenreaktorer; tryckvattenreaktorer; masstransport;

    Sammanfattning : Safety is the top priority at a nuclear facility. The nuclear power plants are designed to prevent radioactive leakage to the surroundings, both during normal operation as well as in case of a severe accident. One of the most important structures in a nuclear power plant, with regard to safety, is thus the reactor containment wall. LÄS MER

  3. 3. Anti-nuclear Movements in Discursive and Political Contexts​ : Between Expert Voices and Local Protests

    Författare :Ekaterina Tarasova; Mai-Brith Schartau; Björn Hassler; Marta Reuter; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social movements; nuclear energy; discourse; action repertoires; protests; Nuclear Renaissance; Russia; Poland; Sweden; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Energy policies which maintain and extend nuclear energy are often opposed by anti-nuclear movements. Ambitious plans for developing nuclear energy in Russia, constructing a first nuclear plant in Poland, and lifting the ban on nuclear energy while allowing the replacement of old reactors in Sweden are examples of such energy policies.

  4. 4. Integration of Non-synchronous Generation - Frequency Dynamics

    Författare :Johan Björnstedt; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency control; Frequency dynamics; Frequency response; Non-synchronous generation; Power system; Synthetic inertia; Wind power;

    Sammanfattning : Traditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. LÄS MER

  5. 5. Omständigheter på ett kärnkraftverk, organisering av risk och institutionalisering av säkerhet

    Författare :Hans Wessblad; Företagsekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Organizational science; institutional theory; ethnography; risk society; tacit knowledge; high reliability organizations; risk technology; risk organization; safety production; Organisationsteori;

    Sammanfattning : Risk societies are made of risk organizations. This dissertation is an ethnographic study of a risk organization, of a nuclear power plant. Risk organizations have larger demands on their organization than traditional companies have. Risk societies, to come or already present, have new political agendas. LÄS MER
