Adsorption and diffusion experiments of Eu III were performed in Callovo-Oxfordian (COx) clay rock in the presence of EDTA. The predictive model based on binary system parameters (Eu/COx and EDTA/COx) was in good agreement with the results for the Eu

Autor: Frédéric Miserque, Nathalie Larabi-Gruet, Jean Radwan, Coralie Gaulard-Balandret, Annie Chaussé, Cécile Ferry
Publikováno v: Electrochimica Acta. 83:471-477
The oxidation and dissolution of UO2 has been studied using electrochemical methods with an UO2 rotating disc electrode in acidic (pH 3) and non-complexing (trifluoromethanesulfonate: 0.1 mol L−1 NaCF3SO3) media. The effect of the experimental para

Europium migration in Argilaceous Rocks : on the use of Micro Laser-Induced Breakdown Spectroscopy (micro LIBS) as a Microanalysis Tool
Autor: Jean Radwan, Patrick Meier, Patrick Mauchien, Michael Descostes, Christophe Poinssot, Denis Menut
Publikováno v: Scopus-Elsevier
Eu migration in a Callovo-Oxfordian argilite sample was studied using the micro LIBS technique. Quantitative elemental mapping were made by micro LIBS that showed the actual distribution of the various micro areas observed on the Callovo-Oxfordian sa

A new criterion for the degradation of a defective spent fuel rod under dry storage conditions based on nuclear ceramic cracking
Autor: François Charollais, Lionel Desgranges, Jean Radwan, Cécile Ferry, Isabelle Felines
Publikováno v: Scopus-Elsevier
Experimental results using environmental SEM on intentionally defected fuel particles showed that oxidation induced cracking could lead to the degradation of HTR coated particles. The interpretation proposed for the swelling resulting from cracking c
