IMT Atlantique, internationally recognised for the quality of its research, is a leading general engineering school under the aegis of the Ministry of Industry and Digital Technology, ranked in the three main international rankings (THE, SHANGHAI, QS).
Located on three campuses, Brest, Nantes and Rennes, IMT Atlantique aims to combine digital technology and energy to transform society and industry through training, research and innovation. It aims to be the leading French higher education and research institution in this field on an international scale. With 290 researchers and permanent lecturers, 1000 publications and 18 M€ of contracts, it supervises 2300 students each year and its training courses are based on cutting-edge research carried out within 6 joint research units: GEPEA, IRISA, LATIM, LABSTICC, LS2N and SUBATECH.
The work will be carried out within the Radiochemistry Team, whose research topics cover a wide range, particularly around the issue of radioactive waste management. The work will be carried out within the framework of the MAEVA project led by Orano on the valorization of depleted uranium.
The project is concerned with developing cement matrices based on depleted uranium oxide. The first part of the modeling contribution will be the calculation of the dose attenuation by the matrices studied in comparison with the usual materials used in the field, such as Portland cement. This will be done using Monte Carlo codes such as MCNP and Serpent.
The second contribution of the modeling will focus on the effects of exposure of new materials to neutron fluxes (as for example in waste containing minor actinides). The possibility of production by neutron capture of minor actinides, in particular Pu, will be evaluated.
The third part will concern the realization of experimental measurements in order to validate the calculations of shielding of the cements. Experiments of alteration of the cements in aqueous medium could be carried out in addition to the studies described above.
