In the remote field eddy current testing, we proposed the method of enhancing the magnetic flux density in the vicinity of an exciter coil by controlling the ma gnetic flux direction for increasing the sensitivity of detecting outer defects on a tube and used the flux guide made of a magnetic material for the method. T he optimum structural shape of the flux guide was designed by the magnetic field analysis. On the experiment with the application of the flux guide, the magneti c flux density increased by 5...

The improvement of defect detection and sizing capabilities for nondestructive inspection technique has been required in order to ensure the reliable operation an d life extension of nuclear power plant. Phased array UT technique has superior capabilities for beam steering and focusing to objective regions, and real time B- scan imaging without mechanical scanning. Water gap phased array UT is capable to apply to inspection of welds of BWR internals such as shroud, shroud support, an d so on. Outline of TO...
