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

    Författare :Sabrina Tietze; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

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

    Författare :Sabrina Tietze; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic iodides; Wet-filter system scrubber ; Chlorine; Volatile iodine source term; Severe nuclear accident; Cables; Sorption; Containment; Paint; Iodine; LWR; Radiolysis;

    Sammanfattning : 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. LÄS MER

  4. 3. Thermal detector with integrated absorber structure for mid-IR gas detection

    Författare :Shakeel Ashraf; Göran Thungström; Peter Enoksson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detectors; Thermopile detectors; Infrared absorbers; SU-8 epoxy; Interferometric and Multi-layered absorber; Seebeck coefficient; Molybdenum di-sulfide;

    Sammanfattning : Measurement of the concentration of greenhouse gases, such as carbon dioxide(CO 2 ) and methane (CH 4 ), in the atmosphere has received significant attention in the last few decades. This work focusses on the development of high-performance thermopile detectors for use with the non-dispersive infrared (NDIR) measurements of such gases. LÄS MER

  5. 4. RuO4 interaction with surfaces in the containment of nuclear power plant

    Författare :Ivan Kajan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; containment; ruthenium; deposition; severe accident; re-vaporization;

    Sammanfattning : During a severe accident different fission products will be released from the nuclear fuel and some of them may eventually reach the containment building. Ruthenium is considered to be an important fission product due to the possible formation of volatile oxides. LÄS MER

  7. 5. Transport and Containment Chemistry of Ruthenium under Severe Accident Conditions in a Nuclear Power Plant

    Författare :Ivan Kajan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fission products; radiolysis; nuclear accident; containment; ruthenium tetroxide; ruthenium;

    Sammanfattning : During a severe nuclear accident volatile elements and elements readily forming volatile compounds are the main concern regarding the release of radioactive material to the environment. As ruthenium is prone to form volatile oxides under severe nuclear accident conditions as well as having radiotoxic isotopes, it is one of the more important elements during such an accident. LÄS MER
