NSUF 21-4359: Improving Lifetime Prediction of Electrical Cables in Containment
Cable degradation accelerates late in the cable's lifetime curve but this phenomena must be validated with experimental data. Researchers will use the Sandia Gamma Irradiation Facility (GIF) to expose nuclear cable insulation samples in sealed containers to a series of gamma doses at a series of dose rates. Oxygen concentration of the sealed containers and dielectric properties of the polymer samples will be measured pre- and post-irradiation. Lifetime curves of the insulation will be determined at more extreme accelerated conditions.
