Aging, condition monitoring, and loss-of-coolant accident (LOCA) tests of class 1E electrical cables
- Sandia National Labs., Albuquerque, NM (United States)
This report describes the results of aging, condition monitoring, and accident testing of miscellaneous cable types. Three sets of cables were aged for up to 9 months under simultaneous thermal ([approx equal]100[degrees]C) and radiation ([approx equal]0.10 kGy/hr) conditions. A sequential accident consisting of high dose rate irradiation ([approx equal]6 kGy/hr) and high temperature steam followed the aging. Also exposed to the accident conditions was a fourth set of cables, which were unaged. The test results indicate that, properly installed, most of the various miscellaneous cable products tested should be able to survive an accident after 60 years for total aging doses of at least 150 kGy or higher (depending on the material) and for moderate ambient temperatures on the order of 45--55[degrees]C (potentially higher or lower, depending on material specific activtion energies and total radiation doses). Mechanical measurements (primarily elongation, modulus, and density) were more effective than electrical measurements for monitoring age-related degradation.
