Oedometric compression and swelling behaviour of the Callovo-Oxfordian argillite
The Callovo-Oxfordian (COx) argillite is a possible host rock for radioactive waste disposal in which the ANDRA underground laboratory of Bure (East of France) has been excavated. In this paper some aspects of the volume change behaviour of the COx argillite are investigated. To do so, high pressure oedometers with a maximum capacity of 113 MPa have been used. In a first stage, swelling tests w...
متن کاملDealing with Geological Discontinuities in Safety Assessment: the Approach of the French Technical Safety Organisation
The present paper focuses on IRSN structural studies aiming at assessing the existence of tectonic structures in the Callovo-Oxfordian clay formation and their potential role on radionuclide transport. IRSN has first determined the type of fracturing that could be present in the Callovo-Oxfordian, by carrying out surface fieldwork in Meuse/Haute-Marne and investigations in clay and limestone la...
متن کاملNumerical modelling of the resaturation of swelling clay with gas injection
During long-term storage of radioactive waste, steel containers are corroded and this process leads to hydrogen production. An in-situ experiment has been designed by Andra, in order to analyze the influence of gas migration on the dynamics of resaturation of the bentonite plug. The competition between liquid water coming from argillite and a gas injection at both ends of the plug is studied. P...
متن کاملInfluence of Operational Parameters and Kinetic Modelling of Catalytic Wet Air Oxidation of Phenol by Al/Zr Pillared Clay Catalyst
Single and mixed oxide Al/Zr-pillared clay (Al/Zr-PILC) catalysts were synthesized and tested for catalytic wet air oxidation (CWAO) of aqueous phenol solution under milder conditions, in a semi-batch reactor. The catalysts were synthesized from natural bentonite clay using ultrasonic treatment during the aging and intercalation steps and were characterized <...
