  1. 1. Advances in Accident Tolerant Fuel Research by Doping of Uranium Nitride

    Författare :Luis Guillermo Gonzalez Fonseca; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Uranium nitride; sintering; internal gelation; doping; ATF; microspheres; density; waterproofing.;

    Sammanfattning : Nuclear energy is a carbon-free energy source alternative often considered less harmful to the environment than fossil fuels. However, accidents have shown that there are some safety concerns regarding nuclear energy that need to be assessed before it can be considered completely safe. LÄS MER

  2. 2. Development of an Environment-Accident Index : A planning tool to protect the environment in case of a chemical spill

    Författare :Åsa Scott Andersson; Mats Tysklind; Ingrid Fängmark; Olof Stjernström; Stellan Fisher; Per Leffler; Ronald Wennersten; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Environment-Accident Index; Chemical Accidents; environmental effects; questionnaire; expert judgements; statistical multivariate design; PCA; PLS; Miljökemi; Environmental chemistry; Miljökemi;

    Sammanfattning : The increasing mass and complexity of chemicals being produced and transported has resulted in more rigorous demands on both authorities as well as chemical-handling industries to assess the risks involved. The Environment-Accident Index (EAI), has been proposed as a planning tool created as an equation in which chemical properties (variables describing the chemical involved) are combined with site-specific properties (variables describing the accident site).

  3. 3. A Chemical Perspective on the Tellurium Source Term in the Context of Severe Nuclear Power Plant Accidents

    Författare :Fredrik Espegren; Chalmers University of Technology; []
    Nyckelord :;

    Sammanfattning : In the event of a severe nuclear accident, one of the biggest concerns is the release of radioactive nuclides. Typically, the most volatile is likely to be released. One that is considered among the most volatile is tellurium. Additionally, health implications towards the public by tellurium can be by itself or the decay product iodine. LÄS MER

  4. 4. Formation, partitioning and interactions of organic iodides under severe nuclear accident conditions

    Författare :Sabrina Tietze; Chalmers University of Technology; []
    Nyckelord :Epoxy paint; Methyl iodide; Iodine source term; Organic iodides; Severe nuclear accidents;

    Sammanfattning : During severe nuclear reactor accidents such as Chernobyl or Fukushima large amounts of radioactive iodine can be released in form of inorganic and organic iodine species into the environment. Volatile radioactive iodine species are harmful to human health when inhaled. LÄS MER

  5. 5. Tellurium Behavior and Management in the Liquid Phases in the Containment During a Severe Nuclear Reactor Accident

    Författare :Anna-Elina Pasi; Chalmers University of Technology; []
    Nyckelord :severe nuclear reactor accident; fission product; source term; tellurium;

    Sammanfattning : No industry is immune to accidents; however, the consequences and the probability are the parameters to consider when assessing the risks. When considering nuclear power, two of the highest-level accidents have occurred during the course of the commercial use of nuclear energy. LÄS MER
