Scope Increased corrosion resistance of the nuclear waste materials is critical to prevent premature degradation of these materials and restrict the escape of radioactive products into environment. Solutions offered to enhance their corrosion resistance and confine active fission products within nuclear storage could alleviate the damaging effects of corrosion on these materials, thereby preventing environment contamination. This symposium will enclose two major research topics: 1) Improvement of the corrosion resistance of nuclear waste storage materials currently in use, including glass, ceramics, and stainless steel. 2) Development of a novel materials system of nuclear waste storage that demonstrates superior corrosion resistance. This symposium will give researchers worldwide an opportunity to discuss specific characterization techniques, including Neutron Diffraction, High-Energy X-ray Diffraction, Extended X-ray absorption fine structure (EXAFS) and Raman Spectroscopy, as well as techniques for ceramic coating inside steel canisters to circumvent the deleterious effect of steel corrosion on nuclear glass in the presence of underground water. Further, the symposium will attract outstanding scientists to present experimental models and atomistic simulation and predictive modeling - Quantitative Structural Property Relationship (QSPR) and Molecular Dynamics Simulations (MD) to model corrosion/ dissolution of glasses. Of particular interest are modeling approaches to study interactions between stainless steel canisters and nuclear glass (or nuclear ceramic) and interactions between glass canisters and nuclear glass in the presence of underground water.
