For nuclear power plants, the safety-related motors which can be exposed to a radiation field have a special insulation system that is designed and qualified to withstand high levels of radiation as a result of regulatory requirements.
However there are often various non-safety motors that are procured with standard commercial insulation systems (no radiation qualification or testing) and exposed to relatively high radiation levels during operation. I am thinking mostly about 13.2kv reactor coolant pump motors which are located inside the bioshield.
Would you expect the radiation to cause any difference in partial discharge occurring inside the insulation or on the winding surfaces?
Would you expect the radiation to cause any difference in the ability to detect actual partial discharge using a partial-discharge sensing coupling capacitor?
