Latest Patents
Maddrell's latest patents include groundbreaking inventions aimed at improving the safety and durability of radioactive waste storage. One of his patents, titled "Encapsulation of Radioactive Waste Using a Sodium Silicate Based Glass Matrix," presents an immobilizing medium designed to encapsulate radioactive waste effectively. This medium utilizes a sodium silicate-based glass matrix that contains radioactive waste, including inert metal components and fission products. The incorporation of inert metals such as iron, nickel, and chromium enhances the durability and leach resistance of the encapsulated waste, making it suitable for long-term storage.
Another significant patent is "Encapsulation of Waste," which focuses on a ceramic waste immobilizing material for high-level radioactive waste (HLW). This invention allows waste ions from fission products in irradiated nuclear fuel to be dissolved in a solid solution form. The ceramic medium comprises phases of hollandite, perovskite, and zirconolite, providing a robust matrix for waste immobilization. The method outlined in this patent involves mixing HLW with precursor materials, drying the slurry, and calcining it to form a powder containing 30–65 weight % waste.
