ABSTRACT:
Method and apparatus for detecting the position of defects in a liquid metal handling instruments such as sodium-heated steam generator, which has a conduit structure invisible from the outside of the instrument. The conduit structure, which is used in a liquid metal, is positioned in a vessel filled with an inert gas. The vessel is sealed whereas a liquid inactive to the liquid metal is filled in the conduit structure. If there exists a defective spot in the conduit structure, the liquid will flow out of the defective spot, which is exactly detected by application of a fiber scope.
