Abstract: An eddy-current flaw detector includes a trace data calculator configured to calculate each coordinate with respect to flaw detection points on which an inspection probe is used upon performing an eddy-current testing based on an inputted condition of eddy-current flaw detection and surface shape data of an inspection-object surface measured by a profilometer, and to calculate a normal vector of each flaw detection point; a gap evaluation calculator configured to acquire an evaluation result on a gap between the inspection-object surface and the inspection probe for each flaw detection point; a flaw detection data collector configured to acquire flaw detection data of an inspection object for each flaw detection point; a flaw detection data analyzer configured to evaluate presence/absence of a flaw in the inspection-object surface based on the flaw detection data of the inspection object and the evaluation result on the gap for each flaw detection point.

Abstract: A reinforcing device includes a clamp that is disposed on an outer side of a welded portion of a core spray system piping and holds the core spray system piping at axially symmetrical points on an outer surface thereof, the piping being located on opposite sides of a weld line of the welded portion and also includes a bolt that is provided on the clamp so as to serve as a mechanical fastening mechanism applying a compressive force to the welded portion from the outside of the core spray system piping.
