Kinetic model for predicting oxidative degradation rates in combined radiation-thermal environments

OSTI ID:5896563
A general theoretical model has been derived for the case of oxidative degradation dominated by the slow breakdown of hydroperoxide species. The model has been used to predict the general dose-rate behavior for this mechanism. The model also suggests a method for creating isothermal dose-rate curves through a time-temperature-dose-rate superposition procedure which utilizes no adjustable parameters. The superposition procedure and the kinetic model are quantitatively verified using accelerated aging laboratory data and real-time nuclear power plant aging data on a PVC material.
