Abstract
Prior to initiating a qualification test on safety related
equipment, the testing sequence for thermal and
irradiation aging exposures must be chosen. Likewise. the
temperature during irradiation must be selected. Typically.
U.S. qualification efforts employ ambient temperature
irradiation, while French qualification efforts employ 700 C irradiations. For several polymer materials, the influence
of the thermal and irradiation aging sequence, as well as the irradiation temperature (ambient versus 70 0 C). has been
investigated in preparation for Loss-of-Coolant Accident
simulated tests. Ultimate tensile properties at completion of aging are
presented for three XLPO and XLPE, five EPR and EPDM, two
CSPE (HYPALON), one CPE, one VAMAC, one polydiallylphtalate.
and one PPS material. Bend test results at completion of aging are presented
for two TEFZEL materials. Permanent set after compression results are presented for
three EPR. one VAMAC, one BUNA N. one Silicone, and one Viton material.
