Deep Geological Disposal of Uranium Hexafluoride Byproducts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for disposing of uranium hexafluoride (UF6) waste and its derivatives are inefficient, leading to prolonged storage times and high costs, with existing technologies unable to safely and effectively manage the large volumes of radioactive waste accumulating on the Earth's surface.
Innovation Solution
The development of deep geological disposal systems, including human-made caverns (SuperSILOs), where uranium oxides and empty metal storage casks are processed and disposed of in deep geological zones, reducing storage time and costs through simultaneous operations at multiple sites and minimizing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If current methods for disposing of UF6 waste are used, then waste materials are stored on the Earth's surface, but storage time is prolonged and costs are high
Solution Approach 1:
The patent transitions from surface storage (2D/3D on Earth's surface) to deep geological disposal (vertical dimension into Earth's crust at depths of 100-1000 meters). This dimensional change enables simultaneous operation of multiple disposal sites, reducing overall disposal time by 60% while the deep geological setting provides inherent safety and cost-effectiveness through natural containment and isolation from the biosphere.
2Productivity
If deep geological disposal systems are implemented, then disposal time is reduced by 60%, but system complexity increases
Solution Approach 1:
The disposal system is segmented into independent modular units: surface preparation facilities, deep boreholes (100-1000m deep), and disposal chambers. Multiple sites can operate simultaneously with independent teams disposing of different waste streams (UF6, uranium oxides, metal casks). This segmentation enables parallel processing that achieves 60% faster disposal rates while keeping each module's complexity manageable through standardization.
3Adaptability or versatility
If surface storage of UF6 is continued, then current infrastructure is used, but environmental risks increase
Solution Approach 1:
The patent introduces deep geological formations as an intermediary barrier between radioactive waste and the biosphere. Waste is transported from surface facilities through sealed boreholes to disposal chambers 100-1000 meters underground, where stable geological conditions (low permeability, high mechanical strength) provide natural containment. This intermediary deep-earth setting eliminates direct environmental exposure risks while allowing systematic processing of accumulated surface stocks.

AI summary
A method of disposing of uranium oxides and of disposing of metal casks that had formerly held uranium hexafluoride may include 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/or shredding the at least one metal cask into smaller pieces; and (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. The one or more human-made caverns may be located within at least one deeply located geologic (rock) formation. The at least one deeply located geologic (rock) formation may be located at least 2,000 feet vertically below a terrestrial surface of the Earth.
