Phased array-based SAFT for defect sizing on power plant components
- Quantitative NDE methods play a key role when it comes to inspect components,
which requires high operational safety. UT-SAFT is one of the well-known reconstruction tools,
which provides information about the defect size. In this work we studied the use of phased array
technique in combination with the SAFT algorithm to inspect power plant components. As a first
example we inspected a real-sized mock-up model representing a part of a reactor pressure vessel with
a 180 mm-thick ferritic base material followed by a 6 mm-thick austenitic cladding layer. The phased
array probe was coupled at the outer ferritic surface. We detected and sized fatigue cracks within the
cladding with a depth ranging from 4 mm to 10 mm. Secondly, we investigated a mock-up model
resembling a nozzle including a thermo sleeve inlet and a maximum wall thickness of about 37 mm.
Artificially inserted notches with a depth of 3 mm could be detected and sized, where the thermo
sleeve is welded at the inside of theQuantitative NDE methods play a key role when it comes to inspect components,
