1. 1. Modeling of Fission Product Behavior in Fast Reactors

   Författare :Karl Samuelsson; Markus Piro; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Den natriumkylda snabbreaktorn är en av kandidaterna till nästa generationens kärnenergisystem. De extrema förhållanden som kärnbränslet utsätts för i en sådan rektor kan leda till säregna konsekvenser. Till dessa hör formationen av så kallad JOG (franska för Joint Oxyde-Gaine = bränsle-kapsel-fog). 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. 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
