nuclear securities : Andra, National Radioactive Waste Management Agency

Line 3, studies on conditioning and long-term near-surface storage. nuclear securities Research in this field includes the development of devices to store waste over several decades under acceptable safety conditions, this work is conducted by the CEA, with assistance from Andra and the CNRS, and is based on information provided by EDF and COGEMA, the chief producers of high-level and long-lived intermediate-level radioactive waste.

Drum containing vitrified waste, as part of its research into the feasibility of a deep geological waste repository, Andra is conducting a programme to acquire date on the clay medium. nuclear securities
The research programme seeks to consolidate knowledge already acquired about the subsurface and the phenomena affecting it, and check that existing computer-based models are relevant, the programme calls on every branch of the earth sciences, engineers create various scenarios to study repository safety. In particular, these scenarios are based on ''''conservative'''' hypotheses to understand, for example, how radioelements would behave in the event of a repository vault sealing failure, general architecture of the Meuse/Haute-Marne Underground Research Laboratory Scientific activities Doctorands’ Day at the ENSCP Andra mobilises scientific skills in a wide range of fields, in particular earth, materials, and environmental sciences, calculation and modelling, measurement and surveillance.

Within this context, it creates, forms and drives the necessary scientific networks with players in the world of research R&D organisations, universities and institutions, through partnerships, service providing, theses and post-doctorate work, the agency also has a policy of training through research, which is aimed at heightening student awareness to the problems of interfacing between the various fields concerned by its scientific programme. nuclear securities This new section covers scientific events congresses, symposia, seminars, areas covered by Andra’s doctorate thesis students, thesis topics and research work under way at Andra, its ambition is to provide the scientific community with more and better information about the agency’s research objectives and results. The french National Radiactive Waste Management Agency is responsible for the long-term management of all radioactive watse in France and for the conduct of investigations on its disposal in deep geological formation.

Andra is recruiting doctoral Ph, d students interested in preparing a thesis for a three-year term. nuclear securities Incumbents will be seconded to a university research laboratory or a post-graduate institution as part of Andra’s efforts to support upstream research in studies associated with radioactive-waste managament, andra is mostly interested in the following topics.

radioactive substance

Couplings and interactions, clays and waste-repository materials, chemistry/transfer couplings, mechanics, geochemistry, fissure plugging. nuclear securities Transfer mechanisms, phenomenon modelling, retention process in engineered and geological barriers, gas migration, inverse modelling of reactive transports.

Geodynamics, evolution of the Paris Basin, long-term seismic risk, erosion quantification and datation. nuclear securities Digital analyses, multi-phenomenon simulation, scale changes, estimates/forecasts, error calculations.
