Uranium hexafluoride byproducts and/or materials disposal

A method of disposing of uranium oxides and of processing metal casks that had formerly held uranium hexafluoride, wherein the method comprises steps of:

• (a) receiving at least a quantity of at least one type of uranium oxide;
• (b) receiving at least one metal cask selected from the metal casks that was formerly housing at least some quantity of the uranium hexafluoride;
• (c) cutting up and shredding the at least one metal cask into smaller pieces;
• wherein the step (c) cutting occurs before the step (c) shredding and outputs from the step (c) cutting are fed as inputs into the step (c) shredding;
• (d) loading at least some of the quantity of the at least one type of uranium oxide and/or loading at least some of the smaller pieces into one or more human-made caverns, wherein the one or more human-made caverns are located within at least one deeply located geologic formation, wherein the at least one deeply located geologic formation is located at least 2,000 feet vertically below a terrestrial surface of the Earth.

• wherein some of the smaller pieces are recycled to serve as metal raw material in an industrial application;
