Radiographic Inspection of Large Diameter Welds at Assembly Site of Fast Reactor Vessel
This paper introduces the selection method for on-site radiographic inspection of the circumferential weld of the reactor shell,including inspection time,radiation source placement,radiographic thickness measurement,pre-radiographic inspection arrangement,shield protection,etc.By adopting special tools such as protective cover,radiographic inspection of the weld is efficiently completed while ensuring safety of the operation personnel and progress of construction.
