2. 1. Physical and Chemical Aspects of Radiation Induced Oxidative Dissolution of UO2

   Author : Olivia Roth; Mats Jonsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; UO2; spent nuclear fuel; dissolution; oxidation; radiolysis; irradiation; particle size; modeling; Chemistry; Kemi;

   Abstract : Denna licensiatavhandling behandlar oxidativ upplösning av UO2. Upplösning av UO2 studeras huvudsakligen då UO2-matrisen hos använt kärnbränsle förväntas fungera som en barriär mot frigörande av radionuklider i ett framtida djupförvar. READ MORE

4. 2. Redox Chemistry in Radiation Induced Dissolution of Spent Nuclear Fuel : from Elementary Reactions to Predictive Modeling

   Author : Olivia Roth; Mats Jonsson; David W. Shoesmith; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear chemistry; Kärnkemi;

   Abstract : The focus of this doctoral thesis is the redox chemistry involved in radiation induced oxidative dissolution of spent nuclear fuel and UO2 (as a model substance for spent nuclear fuel). It is shown that two electron oxidants are more efficient than one electron oxidants in oxidative dissolution of UO2 at low oxidant concentrations. READ MORE
