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

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

    Abstract : 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. READ MORE

  2. 2. The chemistry of organic iodides under severe nuclear accident conditions in LWRs

    Author : Sabrina Tietze; Chalmers University of Technology; []
    Keywords : Organic iodides; Wet-filter system scrubber ; Chlorine; Volatile iodine source term; Severe nuclear accident; Cables; Sorption; Containment; Paint; Iodine; LWR; Radiolysis;

    Abstract : For many countries nuclear fission is an important part of their energy portfolio. However, a great concern is the occurrence of nuclear reactor accidents, which can result in the emission of radioactivity into the environment. READ MORE

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

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

    Abstract : 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. READ MORE

  4. 4. MELCOR Capability Development for Simulation of Debris Bed Coolability

    Author : Yangli Chen; Weimin Ma; Michael Buck; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Severe accident; coolability; MELCOR; COCOMO; surrogate modeling; coupling codes; uncertainty analysis.; Kärnenergiteknik; Nuclear Engineering;

    Abstract : The severe accident management (SAM) strategy for a Nordic boiling water reactor (BWR) employs cavity flooding prior to vessel failure, so that the core melt (corium) discharged from the vessel could fragment and form a particulate debris bed. The key to the success of this SAM strategy is the coolability of ex-vessel debris beds. READ MORE

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

    Author : Fredrik Espegren; Chalmers University of Technology; []
    Keywords : ;

    Abstract : 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. READ MORE
