1. 1. Mobilization and Management of Tellurium in Severe Accident Scenarios

   Författare :Anna-Elina Pasi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nuclear; gamma irradiation; source term; severe accident; tellurium;

   Sammanfattning : Safety is one of the highest priorities in any industry. In the nuclear industry, safety is in the essence since in case of a nuclear accident, the consequences can be long-lasting, hazardous, and devastating to the public, environment, and the industry. LÄS MER

3. 2. Volatized Tellurium Interactions with Organics and with Boric Acid

   Författare :Fredrik Börjesson Sandén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volatile fission product; Severe nuclear reactor accident; Tellurium; boric acid;

   Sammanfattning : Tellurium is a volatile fission product with a complex chemistry that must be accounted for in case of a nuclear accident. Specifically, its interactions with organic species and with boric acid, both which are expected in the accident chemistry, are largely unknown. LÄS MER

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

   Författare :Fredrik Espegren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   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

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

   Författare :Luis Guillermo Gonzalez Fonseca; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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

7. 5. 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
