Evaluation of SAFT/T-SAFT Technology for the Inspection of Hanford's Double Shell Waste Tank Knuckle Regions.

[摘要] Results of the examinations conducted at Pacific Northwest National Laboratory provided a firm engineering basis for establishing the proof-of-principle effectiveness for utilizing a combination of pulse-echo Synthetic Aperture Focusing Technique (SAFT) and tandem-SAFT (T-SAFT) inspection methodologies as applied to the problem of flaw detection, localization, and sizing in Hanford's double shell waste tank knuckle region and beyond.
