Metal disintegration machining apparatus. |
摘要 |
<p>In the replacement of old split-pin assemblies of a guide tube of a nuclear reactor by new split-pin assemblies, each old split-pin assembly is severed into readily removable fragments by metal disintegration machining apparatus. This apparatus includes an insulating block, e.g., of glass and a metal disintegration electrode which is axially perforated, water under pressure is injected into the arc region through the perforation. Also disclosed is a pick-and-put tool, and a crimping tool for crimping a locking cap to the nut of a replaced new split-pin assembly.</p> |
