2019 TMS Annual Meeting & Exhibition: Materials for Molten Salt Energy Systems: Organized by Stephen Raiman; Jinsuo Zhang; Kumar Sridharan; Judith Vidal; Michael Short

The use of molten salts as a coolant in molten salt reactors (MSR) offers many advantages including low operating pressures, high temperatures, and favorable heat transfer. For concentrating solar power systems (CSP), the use of molten salts as a heat transfer medium enables efficient thermal energy storage. Despite the advantages, the highly aggressive molten salts present a challenging environment for salt facing materials. Further, the high temperatures presented by these systems require exceptional mechanical properties. This symposium covers structural and moderator materials in molten salt for nuclear power and concentrating solar power. Abstracts are solicited in the following topics: - Corrosion of salt-facing materials - Salt effects in graphite and moderator materials - Fission product embrittlement - Alloy selection and design for molten salt applications - Interaction of fission products with materials - Mechanical and creep properties - Salt chemistry effects on materials including radiolysis - Heat exchanger design - Welding and cladding issues - Waste handling and actinide recovery

2018 TMS Annual Meeting & Exhibition: Environmentally Assisted Cracking: Theory and Practice: Organized by Bai Cui; Raul Rebak; Sebastien Dryepondt; Srujan Rokkam

Environmentally assisted cracking (EAC) has become a significant limit for the lifetime of structural material components in harsh environments in many fields, such as the oil and natural gas industry, advanced nuclear power plants, and navy applications. The purpose of this symposium is to provide an international forum to foster the discussion of the critical problems in EAC and recent advances in both experiments and modelling. This symposium seeks technical presentations related to experimental and/or modeling studies of various types of EAC, such as hydrogen embrittlement, stress corrosion cracking, corrosion fatigue, and liquid metal embrittlement. The symposium will encompass, but not limited to, the following themes: - Models to understand EAC mechanisms and predict the lifetime of structural materials in harsh environments; - Experimental methods for the performance test of EAC in the laboratory and real environments; - Development of physics-based approaches or multiscale models for EAC monitoring and prognostics; - Fracture and fatigue of alloys in hydrogen environment; - Stress corrosion cracking of alloys in high-temperature water, seawater, or other environment; - Degradation of materials in liquid metal environment; - EAC in additively manufactured parts; - EAC in high-entropy alloys.

2018 TMS Annual Meeting & Exhibition: High Temperature Corrosion of Structural Materials: Organized by Kinga Unocic; David Shifler; Mark Weaver; Steve Coryell; James Earthman

High temperature structural materials are used in aircraft and various industrial applications. Exposure to high temperatures and harsh environments can cause their degradation and subsequent failure of the component or system. This symposium seeks papers that study the effect of: - Alloy’s composition on oxidation and/or corrosion, - Different environments, - Presence of stresses under harsh environments, - Alloys protection using coatings, - Could improve further understanding on alloy oxidation and/or corrosionbehavior.

2018 TMS Annual Meeting & Exhibition: Materials and Fuels for the Current and Advanced Nuclear Reactors VII: Organized by Ramprashad Prabhakaran; Dennis Keiser; Raul Rebak; Clarissa Yablinsky; Anne Campbell

Globally, significant efforts are ongoing to meet the growing energy demand with the increased use of nuclear energy. Extensive work is being performed to develop materials and fuels for the advanced nuclear reactors. In addition, efforts are also ongoing to extend the life of existing nuclear power plants. Scientists, engineers, and students at various national laboratories, universities, and industries are working on a number of materials challenges for the nuclear energy systems. The objective of this symposium is to provide a platform for these researchers to congregate, exhibit and discuss their current research work, in addition to sharing the challenges and solutions with the professional community and thus, shape the future of nuclear energy. Abstracts are solicited in (but not limited to) the following topics: - Nuclear reactor systems - Advanced nuclear fuels - fabrication, performance, and design - Advanced nuclear fuels - properties and modeling - Advanced structural materials - fabrication, joining, properties, and characterization - Lifetime extension of reactors - nuclear materials aging, degradation, and others - Experimental, modeling, and simulation studies - Fundamental science of radiation-material interactions - Irradiation effects in nuclear materials - Materials degradation issues - stress corrosion cracking, corrosion, creep, fatigue, and others - Design of materials for extreme radiation environments - Radiation measurement techniques and modeling studies - Nuclear waste - disposal, transmutation, spent nuclear fuel reprocessing
