Abstract

PURPOSE: To provide a dust protective device which can prevent cut chips and welding dusts from entering the equipment and pipes or the like at the equipment and the pipes disassembling, disconnecting and inspecting time.
CONSTITUTION: In the steam generator for a fast breeder having, for example, steam outlet and inlet 10 and 14, a dust protective device 30 is arragned in a flume state at the lower inside portion of the unit required to be disassembled and disconnected when the top of the tubular plate 11 is opened to plug a heat transmitting tube 12 at the plate 11 if the tube 12 is damaged or when the plate 11 and the tube 12 are inspected during their operations. If the outlet 10 is, for example, flanged, a sealig member 20 interposed between the flanges drops at its cut chips into the tube when loosening bolts 22. The chips thus dropped are received by the dust protective device 30 so as to prevent foreign materials from entering the equipment and the pipes or the like
