Latest Patents

Miyajima holds a patent for a method of processing nuclear fuel scraps. This invention allows for the effective recovery of high-purity uranium from gadolinium-containing nuclear fuel scraps. The process involves dissolving the scraps in a mineral acid, extracting uranium from the resulting solution with a solvent, and washing the organic phase with water or a dilute mineral acid. Additionally, it provides an efficient method for recovering high-purity gadolinium from the acidic washings, which contain small amounts of radioactive elements. This is achieved by adding an alkali, removing the precipitate formed, lowering the pH of the filtrate to 2 or less, and adding an oxalic acid source to precipitate gadolinium oxalate. He has 1 patent to his name.
