A high pressure die casting (HPDC) system for casting ultra-large single-piece castings for vehicles. The HPDC system includes a clear feeding path from at least one ingate to a predetermined thicker section of a mold cavity, a last to solidify ingate having an equivalent or larger feeding modulus than the highest feeding modulus of the other ingates, and thermal management elements. The clear feeding path, last to solidify ingate, and thermal management elements ensure sufficient supplemental molten metal flow to the thicker portion of the mold cavity to accommodate for shrinkage of the thicker portion of an ultra large casting during the casting and solidification process.

A molding machine for molding material is provided. The machine includes a cavity to be filled with molten metal and a conduit system leading to the cavity, thus forming a system of interconnected hollow spaces. At least one pressure member is moveable in at least part of the conduit system. A centrifugal pump in fluid communication with a reservoir of molten metal is provided, the pump providing molten metal to the hollow space receiving the at least one pressure member.

Nuclear waste, such as, but not limited to, spent nuclear fuel (SNF) assemblies or portions thereof, are placed within diecast molds, and then gravity fed molding occurs within those loaded diecast molds and around the SNF assemblies (or portions thereof) that are located within those diecast molds, using molten alloy(s) for filling the diecast molds, to form solid metal ingots (castings) upon sufficient cooling of the newly formed ingots. The molten alloy(s) may contain a copper alloy. The molten alloy(s) may also contain neutron absorbers. Each such formed ingot may entirely encapsulate a SNF assembly (or a portion thereof) within the resolidified alloy(s). 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.

A mold and cavity are coupled to a vacuum tank via a pressure reducing path. A first back-cleaning filter 4a is disposed between the cavity and the vacuum tank in the pressure reducing path. The vacuum tank and the second dry pump are series-connected via a mechanical booster pump. The vacuum tank is sucked by the mechanical booster pump and the second dry pump, thereby always maintaining a predetermined vacuum degree in the vacuum tank. When carrying out die casting, first, after the mold is closed, a release agent is applied on an inner peripheral surface of the mold. Next, while reducing a pressure in the cavity using the vacuum tank, a molten metal is injected to the cavity. When the molten metal is solidified, the mold is opened and a cast product is taken out from the mold.
