Scope As nuclear energy and fuel reprocessing efforts expand, there is an increasing need to generate knowledge on the processing, properties, and testing of materials used in nuclear waste management. Responsible environmental stewardship requires treatment and stabilization of radioactive wastes generated from a wide variety of sources. This symposium will address the immobilization of waste using vitreous cementitious, and composite materials, the material properties of these waste forms and their long-term performance. In addition, the capture and immobilization of radionuclides from off-gas and liquid waste streams will be of interest. High-temperature ceramic, glass, and composite materials as well as alternative low-temperature hydroceramics, geopolymers, and cementitious materials will be discussed. Additional topics include characterization techniques, test methods, and modeling strategies to assess and predict the durability of waste forms on geological time scales. Papers are solicited on a wide variety of topics related to materials aspects in nuclear waste management using experiment, theory, and simulation. This symposium is endorsed by the ACerS Nuclear and Environmental Technology Division.

Abstracts are solicited in (but not limited to) the following topics:
• Waste form materials
• Advances in and design of waste forms and treatment systems
• Advanced waste-form technologies (e.g., vitrification, cementation, and grout)
• Waste treatment for remediation of radionuclides and recycle
• Capture and immobilization of volatile radionuclides
• Sequestration of high-level nuclear waste
• Long-term performance of nuclear waste forms
• International nuclear waste management programs
• The economics of waste treatment strategies
