CX-019622: Development of Cable Aging Acceptance Criteria for Nuclear Facilities – Analysis and Measurement Services Corporation

The Analysis and Measurement Services Corporation, in collaboration with Pacific Northwest National Laboratory and Oak Ridge National Laboratory, proposes to develop acceptance criteria for mechanical, electrical, thermal, and chemical condition monitoring tests that trend with age-related degradation of electrical cables. The work to be performed under the project includes subjecting cables to thermal accelerated aging, radiation exposure, and periodic testing using condition monitoring techniques to trend their properties as they age. After the cable samples have been subjected to thermal and radiation aging, they will then be exposed to loss of coolant accident conditions to determine their point of failure. These  loss of coolant accident test results will be used in conjunction with the condition monitoring data collected during the aging process to develop acceptance criteria that directly correlates with the end-of-life condition of a cable polymer.
