Evaluation of cable polymer aging through Indenter testing of in-plant and laboratory-aged specimens. Final report
- Ogden Environmental and Energy Services Co., Inc., Blue Bell, PA (United States)
This report documents the in-plant testing and evaluation of cables through use of the Ogden/EPRI Polymer Aging Monitor (Indenter), a device that allows nondestructive, in-situ evaluation of the aging of electrical cable insulation and jacketing. Descriptions of the Indenter system and theory of operation, an evaluation of the effectiveness of the system during in-plant trials, and a discussion of artificial aging and cable life projection methodology for various types of common nuclear plant cable are provided. Indenter modulus measurements performed on in-service cables at three Commonwealth Edison nuclear stations (Dresden, Zion, and LaSalle) are compared to the artificial aging results, and the service lives of the cable are predicted.
