Application of advanced ultrasonic test techniques coupled with fatigue and leakage monitoring to assure integrity of BWR feedwater nozzles

Novel SFS-NDT in the field of defect detection

“…Well introduced into application and commonly used NDT methods are liquid penetrant inspection [1], acoustic emission [2], magnetic particle inspection [3], Eddy current inspection [4,5], ultrasonic inspection [6,7], radiography [8,9], and visual inspection [10]. All of them have advantages and disadvantages concerning the detection of special defects in the surface and/or in the bulk volume of a component to inspect.…”
