OECD NEA meeting focuses on irradiation experiments
Members of the OECD Nuclear Energy Agency’s Second Framework for Irradiation Experiments (FIDES-II) joint undertaking gathered from September 29 to October 3 in Ketchum, Idaho, for the technical advisory group and governing board meetings hosted by Idaho National Laboratory. The FIDES-II Framework aims to ensure and foster competences in experimental nuclear fuel and structural materials in-reactor experiments through a diverse set of Joint Experimental Programs (JEEPs).

The effect of various antioxidants and antioxidant concentrations on the room-temperature radiation stability of ethylene propylene diene monomer (EPDM) and cross-linked polyethylene (XLPE) materials used as insulation for electric cable in nuclear power plants is measured. Relative elongation to rupture between aged and unaged material is used as the measure of stability. The materials are irradiated to doses up to 2.0 MGy (200 Mrad) at a dose rate of 300 Gy/h (3 x 104 rad/h) in the Cobalt-60 Gamma Irradiation Facility at the University of Virginia. Several of the antioxidants in EPDM perform well to the maximum doses for which reliable data were obtained of either 1.0 or 1.6 MGy. An XLPE material with Agerite™ MA antioxidant performs well to the maximum dose for which reliable data were obtained of 1.0 MGy. Stabilization at 1.0 MGy increases with increasing antioxidant concentration, though not in proportion to the concentration.
