摘要：

This study investigates the electrical behavior of Ethylene Propylene Rubber (EPR) insulation used in instrumentation and control (I&C) cables in nuclear power plants (NPPs). Cables were subjected to different accelerated radiation aging dose rates, 100 Gy/h and 800 Gy/h respectively. After aging, dissipation factor (tan delta) trend with frequency from 500 Hz to 500 kHz was obtained. Results show that tand of the higher dose rates depicts a faster increase than the lower one, following the aging severity. In particular, the tand trend at high frequencies (greater than 100 kHz) shows a linear increase with aging for both dose rates, proposing it as a suitable radiation aging marker for EPR materials.
