Abstract

The use of holographic interferometry for nondestructive testing (NDT) in nuclear power plants and coal plants is discussed in terms of test code requirements, and is compared with conventional NDT techniques. Holography provides a useful laboratory tool to support the electric utility industry through measurement of deformation, movement, expansion, and vibration. Although optical holography may not have sufficient signal to noise ratio in the power plant environment for the detection of defects buried in thick walled pressure vessels or pipes, it offers a means to measure slight deformations so that pressure vessel integrity could be evaluated directly through response to pressure.
