Remote Visual

Should a detected indication need characterization (i.e. scratch or crack) and/or sizing; methods such as Eddy Current or the WesDyne Replica technique( RMT) can be applied.

WesDyne entertains a large amount of qualified camera systems and tools for different inspection applications.

Laser modules are commonly used for providing references in order to size and measure foreign objects and indications.

Camera handling and positioning can be performed by submarines, mechanized platforms or manually (using e.g. handling poles), depending on needs.

WesDyne has long experience of Visual Inspection/Testing (VT) in Nuclear Power Plants; both Boiling Water Reactors (BWR) and Pressure Water Reactors (PWR). WesDyne routinely performs virtually all kinds of visual inspections in the Reactor Pressure Vessel and of internal components.

In addition to standard visual inspections, WesDyne has developed and qualified a generic visual inspection procedure (VT-01) for use at Swedish nuclear power plants. The development was made in close collaboration with the Swedish nuclear industry and power plants

The VT-01 procedure allows for reliable detection of cracks down to a width of 20 µm and a length of ≥5 mm.
