An injection device of a light metal injection molding machine includes: a first inert gas storage part creating an inert gas atmosphere around a plunger insertion port of an injection cylinder; a second inert gas storage part housing surplus molten metal in a melting cylinder and creating an inert gas atmosphere above the molten metal; and a first pressure adjustment part adjusting a pressure in the first inert gas storage part to a pressure equal to or less than a pressure obtained by adding a pressure, which is determined based on a value obtained by multiplying a specific gravity of the molten metal by a height difference between a highest position and a lowest position of the molten metal in a part that includes the inside of the injection cylinder and communicates with the inside of the injection cylinder, and a pressure in the second inert gas storage part.

A slurrying device includes a slurrying tank and a rotor stirrer. The rotor stirrer includes a stirring drum, a transmission gear arranged at an end face of the stirring drum configured to face the slurrying tank, and a rotor stirring rod configured to extend from the stirring drum and into the slurrying tank to stir a slurrying liquid in the slurrying tank. The rotor stirring rod is meshed with the transmission gear and configured to revolve along a planar trajectory of the transmission gear while simultaneously rotating. The rotor stirrer further includes a driving device provided at the stirring drum and configured to drive the rotor stirring rod to rotate via the transmission gear.

Disclosed is an apparatus for loading one or more alloy ingots into a molding machine. The apparatus includes a holder configured to hold a plurality of the alloy ingots and dispense one or more of the alloy ingots into a melt zone of the molding machine through an opening in a mold of the machine. The holder is moved in a perpendicular direction with respect to an axis along a center of the opening in the mold between a first position in line with the opening in the mold to dispense one or more of the alloy ingots and a second position away from the opening in the mold. The apparatus can carry ingots of amorphous alloy material so that when the machine melts and molds the material, it forms a bulk amorphous alloy containing part.

Nuclear waste, such as, but not limited to, spent nuclear fuel (SNF) assemblies or portions thereof, are placed within diecast molds, and then diecast injection molding occurs within the diecast molds and around the SNF assemblies or portions thereof that are emplaced within those diecast molds, with injected molten alloy(s), to form solid metal ingots upon sufficient cooling after the injection that contain within the ingots the emplaced SNF assemblies or portions thereof. The molten alloy(s) may contain a copper alloy. The molten alloy(s) may also contain neutron absorbers. The ingots may be placed into waste capsules. The ingots and/or the waste capsules may be landed in deeply located horizontal wellbores. The deeply located horizontal wellbores may be at least partially located within deeply located geologic formations.
