Effect of the Dose Rate and Temperature on Radiation-Induced Charge Separation in Cables with Mineral Insulation under Pulsed Reactor Irradiation

The results of studying the level of charge separation between the core and sheath in cables with mineral insulation and nickel and stainless-steel conductors are presented. The cables were irradiated in a BARS-6 pulsed reactor with dose rates of 3 × 103 and 4 × 103 Gy/s at temperatures of 270–650 K. A mechanism for elucidating the complex temperature dependence of the level of temperature-induced charge separation is proposed.
