Method of drying high-level radioactive wastes and device thereof

摘要

A method of drying high-level radioactive wastes and device thereof contains a suspension mechanism for hanging a manual elevating mechanism, and a shielding cover. The manual elevating mechanism couples with a basket for accommodating wastes by using a hanging rope, and the shielding cover is fixed below the suspension mechanism and in a moving path of the basket. The basket is moved to a storage tank containing water in which radioactive wastes are stored, and the radioactive wastes are pumped into the basket by means of a pump. The basket is then lifted above a water surface of the storage tank and received in the shielding cover, and then the shielding cover is moved into a water holder so as to drain waters in the basket. The basket is further moved onto a heating seat to be heated and a vacuum equipment is started to dry the radioactive wastes.

主权项

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 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.
