Abstract Scope |
EPDM (Ethylene Propylene Diene Monomer) is a rubber often used as an insulator in the electrical wiring of nuclear power plants. During its operational life, the material is exposed to various aging mechanisms including radio-oxidation and thermo-oxidation. Consequently, the outer surface of insulator undergoes changes in properties over time as a result of combined mechanical and chemical processes,
leading to the appearance of cracks and thus to the failure of the electric cable.
The insulation material end-of-life criterion is based on a standard which prescribes a minimum value of the elongation at break not less than 50% (absolute value). Our work consists in studying the influence of radiation and thermal aging on the properties of rubber. The goal is to propose a tool allowing the prediction of mechanical properties at break during aging. |
