  1. 21. 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. 25. Precipitation and fixation of uranium in reduced environment : simulation in a continuous culture of sulfate-reducing bacteria

    Författare :Ulf G. Edvardsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The precipitation and fixation of the uranyl ion (U022+), in a reduced environment, has been investigated by means of continuous cultivation of sulphate-reducing bacteria. The continuous culture sustem made it possible to study the chemical reactions under physico-chemical conditions (e.g. LÄS MER
