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

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

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

  5. 3. Investigation of the behaviour of gaseous I2 and RuO4 in different atmospheres

    Author : Joachim Holm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; containment; deposition; iodine; gaseous-phase reactions; ruthenium; PWR; BWR;

    Abstract : During a severe accident several hazardous and radiotoxic fission products can be released and constitute a threat to the environment. Two of the most important fission products are iodine and ruthenium which will be accumulated after inhalation in the human body in the thyroid gland and in the respiratory organs, respectively.
