ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

Polymeric materials widely used in safety-related equipment are relatively vulnerable to severe environments such as high temperature and radiation environment during the severe accident. Therefore, to ensure the integrity and performance of the safety-related equipment, degradation effect of severe accident on polymer must be investigated.
In this paper, to evaluate the degradation effect of radiation and heat during normal operating condition and severe accident environment, hardness measurement and tensile test were carried out. And FT-IR analysis was conducted to investigate the molecular structure and bonds. The mechanical properties were not changed significantly in pre-aging, normal operating condition. But radiation of severe accident environment significantly affects the mechanical properties of fluoroelastomer and molecular structure, such as C=O formation.
