Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Safety assessment of a deep geological repository for radioactive wastes (IHLLW) requires identification of potential flow paths and the associated travel times for radionuclides originating at repository depth. The planned French repository will be located at great depths in the Callovo-Oxfordian clay formation of the multi-layered system of Paris Basin. Hydrogeological performance of the planned radioactive waste repository relies on analysis and assessment of the geodynamic evolution impact on groundwater flow behaviour in the multi-layered aquifer system through the next million of years. Numerical simulations coupling the geodynamic evolution and the groundwater flow describe how the tectonic uplift and erosion/sedimentation processes affect (i) the long term transient flow behaviour and (ii) the hydrogeological performance measures. Hydrogeological performance assessment of the potential repository site is performed by the use of particles transport model using a 3D transient flow field induced by: (i) deformation of the multi-layered aquifer system resulting from the differential tectonic uplift, (ii) evolution of the outcrop zones governed by erosion and incision of the geological layers and (iii) the climate changes. Outlets of the hydrogeological system are located and the associated transit times from the repository are estimated.
