Abstract

Ultrasonic techniques are widely used for a variety of diagnostic and monitoring purposes. The ability to transmit and receive signals through pressure boundaries, and their proven accuracy in measuring flow have made them essential to the nuclear industry, particularly for flaw detection and flow measurements.
We review the current use of ultrasonic technology in applications to nuclear power plants and report on recent advances in ultrasonic flow-measurement technology, including adaptations of cross correlation techniques and tests of specialized transducers. We suggest a number of potential but clearly achievable improvements in ultrasonic technology that could improve its usefulness to nuclear operators.
