The symposium centers on the scientific foundations of nuclear waste management, emphasizing material science insights into waste forms, engineered barriers, and far‑field interactions beyond conventional engineering practices. Proceedings are organized into thematic sections covering spent fuel, glass and crystalline waste forms, performance mechanisms and models, cementitious materials, container alteration, microbiologically influenced corrosion, near‑field interactions, natural analogues, long‑term barrier predictions, performance assessment of engineered barriers and geological systems, and radionuclide chemistry and transport. Selected papers are catalogued separately for inclusion in the Energy Science and Technology Database.
One most significant aspect of this particular symposium is the focus on the scientific basis for management of nuclear waste. Engineering principles and practices are important, but this symposium focuses on the science. The extension and application of engineering ``know how`` to waste management problems sometimes requires a degree of understanding not normally needed to solve other engineering problems. In materials science, for example, scientific understandings important to long-term behavior may be obtained from (1) characterizations and analyses of the structure and properties of materials, (2) the recognition of advancements needed to ensure performance, and (3) improvements in methods of fabrication and processing. In addition to the materials science topics addressed here (on waste forms, engineered barrier systems, and the near-field environment), the symposium addressed various far-field topics. The proceedings are divided into the following sections: spent fuel; glass and crystalline waste forms; glass performance--mechanisms and models; cementitious materials; container alteration; microbiologically influenced corrosion; near-field interactions; natural analogues; long-term prediction for engineered barriers; performance assessment of engineered barrier systems; radionuclide chemistry and transport; and performance assessment of geological systems. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.
