Abstract
Flame-retardant cross-linked polyolefin (FR-XLPO) is important insulating material for electric cables in nuclear power plants. Safety-related cables in a nuclear power plant must withstand high temperature and radiation during the normal operation and additional concurrent high-temperature steam and high-dose-rate radiation when an accident occurs. In this study, the degradation behavior of FR-XLPO under simulated accident conditions was investigated. As a result, it has become clear that FR-XLPO is resistant to gamma rays and superheated steam, especially in the absence of oxygen.
