Abstract:
1. An apparatus for performing an automated cleaning of nuclear fuel cladding-tubes, the apparatus comprising: a cleaning material supplying section having a cleaning material automatic supplying device for automatically aligning and supplying a cleaning material, a cleaning material transferring device connected to the cleaning material automatic supplying device at its terminal end and configured to transfer the cleaning material supplied from the cleaning material supplying device into a cleaning section, and a cleaning solution supplying device configured to spray a cleaning solution to the cleaning material transferred by the cleaning material transferring device; wherein the cleaning section includes an air gun configured to eject the cleaning material transferred by the transferring device by a pneumatic pressure blast from a nozzle, a first pneumatic cylinder fixed to the air gun and connected to an inlet hole of the air gun by using a tube for supplying air pressure to the air gun, a second pneumatic cylinder connected with the first pneumatic cylinder and configured to transfer the first pneumatic cylinder and the air gun, and a fixed frame facing an end of the air gun and having an accommodation space configured to receive the ejected cleaning material and a cladding-tube, wherein the cleaning solution supplying device is connected with an upper side of the fixed frame, and the cleaning material transferring device transfers the cleaning material to a position between the accommodation space of the fixed frame and the end of the air gun, and wherein the cleaning material automatic supplying device includes a storage container, a piezoelectric element attached to the bottom of the storage container, an aligning passageway formed in an inclined spiral form along the inner wall face of the storage container, and a one-line supply device connected with the aligning passageway to supply in one row a cleaning material coming from the storage container.
