摘要：
This report describes the development of a portable boiler tube wall thickness gauge. The instrument relies upon a layer of magnetostrictive oxide on the tube surface to generate ultrasound. Details are given of an assessment of the instrument on sample tubes supplied by the CEA and on field trials at Nova Scotia Powers Trenton Plant.
