Abstract:
1. A method of drying high-level radioactive wastes comprising steps of: placing a basket into a water tank in which radioactive wastes are stored and collecting the radioactive wastes in the basket, wherein a hanging device moves a basket to a storage tanks containing water in which radioactive wastes are stored, and the radioactive wastes in the storage tanks are moved into the basket; moving the basket out of the water tank and placing the basket in a shielding cover; wherein the basket for collecting the radioactive wastes is lifted through a suspension mechanism and elevating mechanism above a water surface of the storage tank and is received in the shielding cover so that the basket moves the radioactive wastes without exposing radiation; moving the basket into a water holder so as to drain water drops, wherein the basket is moved into a water holding groove of the water holder so as to drain the waters contained in the radioactive wastes; and hanging the basket on a heating tray and connecting the shielding cover with a vacuuming equipment so as to dry the radioactive wastes, wherein a vacuum equipment is connected with the shielding cover so as to heat and vacuum free waters in the radioactive wastes, wherein the through hole of the shielding cover is covered up with the cap through the elevating mechanism during vacuuming process.
