Apparatus for the in-situ inspection of tubes while submerged in a liquid

Creators

Description

Before inspecting the tubes in a nuclear steam generator it has previously been necessary to drain the tubes of primary coolant. This invention provides an apparatus which makes it possible to inspect steam generator tubes which are partially filled with primary coolant. An eddy current sensor and its cable pass through a conduit into which a drying medium such as compressed air is introduced, removing coolant adhering to the surface of the cable. (LL)
