Abstract
Locations of corrosion on the floor plate of cylinder tank of 32.92m in diameter and 14m in height was estimated by monitoring of AE propagating on the floor plate. The AEs were produced by rust fractures. AE source location was performed by a virtual source scanning method. An average error of AE source location for artificial source was approximately 3m. AE source for rust fracture was concentrated at the place where wall reduction inspected by pulse echo method.
