Comparison of radiation and thermal ageing simulation procedures for NPP cables
Original language description
The accelerated radiation and thermal ageing of cables has a speciál importance in the type qualification test of NPP cables as it should provide for the cable ageing by an accelerated but reál process of ageing, i.e., by the homogeneous oxidation of thecable polymeric matenals. A comparison of three cable ageing techniques was performed on the representative NPP cables based on EVA and XLPE jacket and insulation materials. These techniques cover separated and combined radiation and thermal ageing under high dose rate (3 kGy/h) and low dose rate (5 Gy/h) in temperatures from 75 °C to 150 °C. The results of mechanical and physico - chemical properties are discussed and a recommendation for qualification test procedures are proposed.
