NSUF 19-2878: Ion-Irradiation and Microstructural Change Studies of Glassy Carbon
Glassy carbon has received increasing attention for being studied as a promising core material for advanced nuclear technologies. Compared to extensive studies of the irradiation effects in nuclear graphite, the influences of neutron or ion irradiation on the mechanical, electrical, and thermal properties of glassy carbon have been rarely reported. It has unique physical and chemical properties substantially different from those of graphite. The neutron or ion irradiation of the materials is likely to cause considerable changes of its physicochemical and mechanical properties, and even its transformation into graphitic materials. The PIE studies by several established methods will allow to disclose their microstructure and develop the relationship between the structure, property, and irradiation conditions. The systematic studies of irradiation effects in glassy carbon are important for boosting the design and development of high-performance fuel elements for advanced nuclear technologies and deepening our understanding of physicochemical property changes of the glassy carbon materials in nuclear environments. This project will initiate a preliminary systematic study and begin experiments to irradiate the glassy carbon material and examine the microstructural changes of the irradiated material.
