Novel non-contact non-destructive analysis technique is developed to probe quantitatively the degree of chemical degradation of polymers used in the nuclear power plants by use of microwave absorption spectroscopy. Degradation of polyethylenes (PE), ethylene-propylene rubbers (EPR), and polysiloxanes (silicones: SR), which are typically used in the BWR and PWR respectively as coatings of electrical cable, are monitored by the microwave resonance measurement (MRM). The polymers set in the cavity of microwave causes considerable resonance frequency shifts which show good correlation with the mechanical property changes. The correlation factors observed are 0.99 for EPR and 0.92 for SR between the frequency and break elongation degradation induced by thermal degradation, and the maximum factor of 0.94 between the frequency and the break elongation degradation induced by radiation.
