... Tubular samples of Zircaloy-4 clad, of the standard 17 × 17 PWR design, in the cold worked, stress relieved condition, with a mean wall thickness ξ = 580 μm, and samples machined to reduce their wall thickness to 200 and 80 μm, respectively, have been oxidized in air at one bar pressure...

... Although a rapid, accurate, and easy-to-use inspection method for steam-generator tubes is clearly needed, it is not entirely provided by our present eddy-current tests. The signals from eddy-current tests are affected by changes in tube wall thickness, the location and size of defects...
