Paper Abstract

Speckle interferometry has been used to monitor the change of strain in a hydride blister in a specimen of zirconium pressure tubing used in a nuclear power reactor. The change of in-plane strain due to migration of hydrogen in the heated sample was observed through use of two illumination beams. Day-to-day speckle interferograms were obtained using a computer to control the relative optical phase of the two beams. Good qualitative agreement was found between strain measured in this work and that predicted by a metallurgical model.
