• Abstract
  A synergistic combination of science-based modeling, multiscale simulations and embedded experiments is increasingly viewed as an optimal framework for the design and analysis of advanced nuclear energy systems. In the last decade, the predictive capabilities of simulations have achieved a high level of maturity through the development of electronic structure algorithms, molecular dynamics (MD), continuum methods, and through significant improvements in the computing hardware. It has now become possible to link the macroscopic physical and chemical behavior all the way down to the nanoscale where the mechanisms are understood at a fundamental level.

  This talk will cover several areas where nanomaterials and multiscale simulations can potentially play an important role in nuclear engineering. Examples include analysis of nanofluids for improved coolant properties, viscous transport in glassy materials, design of nanostructured materials for improved radiation tolerance, coupled MD-continuum analysis of material deformation and transport at an ablative plasma-wall interface.
