Zusammenfassung:PROBLEM TO BE SOLVED: To perform efficient polishing work by eliminating waiting time loss, preventing an abrasive from scattering during polishing of a nozzle, and recovering the abrasive after the polishing. SOLUTION: The local polishing work system in a building of a thermal power plant and a nuclear power plant comprises a nozzle rack area for storing the nozzle, a carry-in area for the nozzle, and a polishing area equipped with a polishing device for polishing the nozzle by injecting the abrasive, the respective areas being disposed in the shape of a line. A portal crane capable of performing conveying, reversing, and assembling work of the nozzle is installed so as to span across the respective areas. The portal crane enables the conveyance of the nozzle between the respective areas. COPYRIGHT: (C)2010,JPO&INPIT
