Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.

This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract

Formation of cracks on the inner walls of nozzles of Boiling Water Reactors would be of great concern for nuclear power industry. These nozzles, which connect the piping to the pressure vessel of the nuclear reactors, are therefore inspected periodically using ultrasound. However, there are complications in ultrasonic inspection of such nozzles due to the curvature of these components. Such curvatures can greatly influence the wave propagation through them. Therefore, there is a need for practical beam models to study such complications in these kinds of geometries.
