Condition monitoring and aging assessment of Class 1E cables
Sandia National Laboratories is currently conducting long-term aging research on representative samples of nuclear power plant Class 1E cables. The objectives of this program are to determine the suitability of these cables for extended life (beyond 40 year design basis) and to assess various cable condition monitoring (CM) techniques for predicting remaining cable life. The cables are being aged for long times at relatively mild exposure conditions with various CM techniques being employed during the aging process. Following the aging process, the cables will be exposed to a sequential accident profile consisting of high dose rate irradiation followed by a simulated design basis loss-of-coolant accident (LOCA) steam exposure. This paper covers two aspects of the research program: the electrical measurement techniques that have been developed and are being performed and some initial data that has been generated from these measurement techniques. The electrical measurements include insulation resistance, polarization index, capacitance, and dissipation factor.
