ABSTRACT:
A device for evacuating, filling and closing final storage containers for dioactive materials mixed with molten glass, comprising a suction pipe connected to the container, a meltable closure for said pipe and a closable evacuation connection fitting mounting in said meltable closure. The container is evacuated through the fitting whereupon the fitting is sealed closed to preserve the vacuum. When the suction pipe is dipped into the molten glass to fill the container, the closure melts and with the glass is sucked into the container.
In another form the device also includes a protective sleeve surrounding the fitting, closed at its outer end with a meltable plate which also serves as a heat radiation shield. The shield prevents premature melting of the meltable closure, i.e. melting from the heat in the glass furnace prior to immersion of the suction pipe in the molten glass.
The invention also includes a closure for the filled container which may be soldered at its periphery to the container wall by induction heating to seal the container.
