Description

Advances in fracture mechanics techniques used to perform structural analyses of weld zones in nuclear reactor pressure vessels have generated an increasing need for more accurate data than can be provided by current in-service (ISI) pulse-echo ultra sonic (UT) methods. Because of its ability to provide good resolution in thick sections, holography has been suggested as a method of sizing and characterizing indications in reactor pressure vessels (Collins and Gribble, 1972). The Production Prototype Pressure Vessel Imaging System (PVIS) described here was developed for the Electric Power Research Institute (EPRI) as an add-on tool for existing pressurized water reactor (PWR) ISI equipment.

High-Resolution Imaging of Thick Sections and Specimens with Irregular Surfaces Using Scanned Acoustical Holography
