Abstract

Electromagnetic acoustic resonance (EMAR) with "superposition of the nth compression" signal processing was applied to measure the thickness of pipes in nuclear power plants and to assess its feasibility. Thickness values evaluated by EMAR agreed well with those obtained using an ultrasonic thickness gauge. In addition, as a non-contact measurement method, EMAR decreases measurement times of pipe inspections in nuclear power plants.
