Abstract
Here we report the Post-Irradiation Examination planned for the AGC-1 creep samples. The key data obtained for each grade of graphite included in the AGC-1capsule are:
• Dimension, volume, mass and density changes
• Creep strain
• Electrical resistivity
• Elastic constants (E, G, υ) from sonic velocity
• Dynamic modulus (from fundamental frequency of vibration)
• Coefficient of thermal expansion
• Microstructural characterization
• Fracture strength
The effect of creep strain on the above properties will be determined.
These data are critical to the design of the Next Generation Nuclear Plant. Moreover, the data supports ongoing work in the area of model development, e.g., irradiation effects models such as dimensional change. The data will be used to help underpin the existing American Society of Mechanical Engineers (ASME) design code for graphite core components.
