Flame-retardant cross-linked polyolefin (FR-XLPO), is widely used as insulators for electric cables. Several cables installed in nuclear power plants must be functional even when they suffer a severe accident. Therefore, sheets of FR-XLPO were exposed to heat, gamma rays, and high-temperature steam. Before and after such aging treatments, samples' mechanical and thermal properties and infrared and THz absorption spectra were measured. As a result, it has become clear that FR-XLPO is fairly resistant to superheated steam with no oxygen, although it is easily degraded thermally if oxygen is present. It is also resistant to gamma rays to a certain extent.
