Abstract

Provided is a method of producing radio-active waste package. By evaporating and drying, the radio-active waste is reduced to a radio-active powder which is formed into pellets in order to ease its disposal. The pellets are received in a container and then impregnated therein with a thermoplastic composition so as to be integrally solidify in the container. The prior technical method cannot fully impregnate the pellets with the thermoplastic material. The present invention improves the prior art technical method of producing radio-active waste package thereby to eliminate the above disadvantage. The present invention also provides a device for carrying out the above method.
