EXTRACTION GUIDE FOR EXTRACTION OF FUEL ROD FROM SPENT NUCLEAR FUEL ROD TUBE

摘要

The present invention relates to a general-purpose drawing guide for drawing a nuclear fuel rod from a spent nuclear fuel rod storage tube. The present invention comprises an upper guide which has an upper through hole at the center and a protrusion pin connected to a lug rope protruding from the upper part; a central guide the upper end of which is spirally inserted inside the upper guide and which has a central through hole communicating with the upper through hole at the center when being combined with the upper guide; a lower guide the lower end of which is spirally inserted and which has a lower through hole communicating with the central through hole when being combined with the central guide; and an extension cap which is spirally combined with the lower end of the lower guide. The central guide and the extension cap easily draw out a nuclear fuel rod protruding in different heights from a nuclear fuel rod storage tube as well as reliably draw out the nuclear fuel rod without damage by being made up of selected one among multiple different lengths.
