Jacobus, M J

Sandia National Laboratories is conducting long-term aging research on representative samples of nuclear power plant Class 1E cables. This paper provides some results of mechanical measurements that were performed on ethylene propylene rubber (EPR) cables and cable materials aged at relatively mild, simultaneous thermal and radiation exposure conditions for periods of up to nine months. The mechanical measurements discussed include tensile strength, ultimate elongation, hardness, and compressive modulus. The modulus measurements were performed using an indenter developed at Franklin Research Center under Electric Power Research Institute (EPRI) sponsorship. 10 refs., 19 figs., 2 tabs.
