PACRIM S29: Ceramics and Ceramic Matrix Composites for Next Generation Nuclear Energy

Advanced ceramics and ceramic matrix composites (CMCs) are attractive for next generation nuclear energy systems, as they increase the operating temperature window to allow higher thermal efficiency. Ceramics and CMCs have been used or proposed as fuels forms, cladding, or structural materials for light water and advanced reactors. As such, considerable research has been dedicated around these systems. These materials also contribute to enhanced safety of nuclear systems, including light water reactors, due to their high temperature capability.

Moreover, the use of these materials mitigates long-term waste disposal due to low-activation. Processing, properties, and testing of traditional glass and cementitious materials need to be expanded to meet the future needs of the nuclear industry. This symposium discusses current state of the art including processing, fundamental materials science issues, and practical aspects of their deployment.
