  2. 1. 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

  4. 2. Tellurium interaction with surfaces in the containment and sea-salt residue

    Author : Fredrik Espegren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; server nuclear accident; Keywords: tellurium; seawater; deposition; chemistry; containment;

    Abstract : In the event of a nuclear accident, the release of radionuclides is always a concern. The extent of such releases is affected by several factors, for example type of atmosphere, temperature, and what structural materials are present during the accident. READ MORE

  5. 3. 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.

  6. 4. Structural integrity of prestressed nuclear reactor containments

    Author : Patrick Anderson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel liner; reliability; relaxation; shrinkage; creep; loss of prestress; tendon; Nuclear; containment; design pressure; Construction technology; Anläggningsteknik;

    Abstract : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. READ MORE

  7. 5. Iodine-Metal Surface Interactions under Severe Accident Conditions in a Nuclear Power Plant

    Author : Henrik Glänneskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; containment; reactive metals; BWR; adsorption; iodine; radiolysis;

    Abstract : In the event of a severe nuclear reactor accident, iodine will be released from the fuel and eventually enter the containment. Radioactive iodine isotopes constitute both an acute and a long-term threat to humans, owing to its half-life and its accumulation in the thyroid gland. READ MORE
