Abstract

An automatic pallet loading/unloading method for radioactive waste drums is disclosed, which comprises the steps of: (a) providing a conveying pallet accommodating six radioactive waste drums; (b) arranging the pallet on a specific importing carrier; (c) performing a two-dimensional fetching position adjustment upon the pallet by the importing carrier; and (d) using a grabber crane to grab and carry the radioactive waste drums in a specific order so as to apply an continuous inspection process upon each radioactive waste drum successively. In a preferred aspect, the two-dimensional fetching position adjustment uses a transverse positioning operation cooperating with a lengthwise positioning operation to successively place each radioactive waste drum in a specific position to be grabbed by the grabber crane and thus to be inspected by the inspection process. In addition, an exporting carrier with two-dimensional position adjustment ability similar to that of the importing carrier is provided for receiving those radioactive waste drums after each has completed the inspection process, whereas an empty pallet placed on the carrier is moved with respect to the two-dimensional position adjustment of the exporting carrier so as to enable the radioactive waste drums after being inspected to set on the pallet in order appropriately. By the method of the invention, an automatic inspection process for radioactive waste drums can be achieved so as to prevent operators from getting radiation damage due to the exposure in radiation environment while operating inspection.
