OSTI ID:4036797
Sub-size impact specimens of annealed and cold-worked Zircaloy-2 were irradiated at 220 deg C with 3.6 x 10/sup 19/ n/cm/sup 2/, at 280 deg C with 2.7 x 10/sup 20/ n/cm/sup 2/, and then tested. It was found that the irradiation had very little effect on the impact properties of either the cold-worked or the annealed material. Results are given on the effect of a hydride precipitate on the impact properties of unirradiated material. Hydride layers approximately 10 mu m thick were deposited electrolytically on annealed Zircaloy-2 impact specimens. The presence of the hydride layer did not effect the impact properties. Drop weight tests were performed on specimens taken from annealed Zircaloy-2 plate. Catastrophic crack propagation occurred below --115 deg C for specimens containing 7-ppm hydrogen and below --80 deg C for those containing 30- ppm hydrogen. (auth)
