Method of drying high-level radioactive wastes and device thereof

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 B 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 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.
