Cladding separate effects study: ORNL clad-beam studies

The primary objective of this irradiation series is to establish the amount of radiation-induced temperature shift that occurs in the K/sub Ia/ curve of two high-copper weldments typical of those in older light-water reactor pressure vessels. These results in conjunction with those of the Fifth Series, which will determine the shifts in the K/sub Ic/ curve, Charpy impact curve, and nil-ductility drop-weight temperature will allow an assessment of the currently used correlation of the K/sub IR/ curve shift being equated to the shift in RT/sub NDT/. Toward this aim the high-copper weldments and irradiations of the Sixth Series are identical to those of the Fifth Series
