Hydride reorientation and delayed hydrogen cracking have been evaluated in specimens cut from the longitudinal and circumferential directions of cold-worked Zr-2.5Nb pressure tubes. In this material basal plane normals were highly concentrated in the circumferential direction. In longitudinal specimens hydrides did not reorient, cracks were not initiated, and artificial cracks grew slowly and only at
