Scope Nuclear energy offers a viable solution to the world’s increasing demand for electricity, state’s dependence on imported oil, and global air pollution and climate change. However, an increasing inventory of nuclear waste poses a significant environmental challenge. The expectations of waste form materials performance are stringent due to the need for long term stewardship of nuclear waste. Nuclear waste comprises a variety of materials requiring different types of management to protect people and the environment. New or improved technologies and materials are needed to achieve safe and hazard-free generation, processing, storage, transport, and disposal of nuclear waste. In addition, a better scientific understanding of the processes and mechanisms underlying the long-term behavior of waste forms is needed.

This symposium will discuss fundamental and applied scientific topics related to materials issues in nuclear waste management. The symposium will include a special session “The Impact of Extended Dry Storage on Used Nuclear Fuel” focused on topics aimed at understanding uncertainties (environmental conditions that are present on the surface of the storage containers and the electrochemical properties of the storage containers) associated with the interim storage of used nuclear fuel. The symposium will feature the internationally renowned speakers and leading researchers investigating novel materials and technologies using experiments, theory, mathematical and physical modeling, and simulation.
Abstracts are solicited in (but not limited to) the following topics:
• Waste forms
• Advanced waste-form technologies (e.g., vitrification, cementation, and grout)
• Waste treatment for remediation of radionuclides
• Volatile radionuclide removal and immobilization
• Sequestration of high-level nuclear waste
• Special session “The Impact of Extended Dry Storage on Used Nuclear Fuel”
• Nuclear waste management programs around the world
• Cross-cutting topics
