Latest Patents

Amamoto's latest patents focus on advanced reprocessing methods utilizing fluoride volatility processes. The first patent describes a method that involves subjecting fluorine or a fluorine compound to a reaction with spent oxide fuel. This process produces fluorides of uranium and plutonium, which are then recovered based on their volatility behavior. The method includes several steps, such as fluorinating uranium and plutonium into UF6 and PuF6, and fractionating these compounds to prevent the formation of intermediate fluorides that are difficult to react. This innovative approach not only minimizes reactor corrosion but also reduces the consumption of expensive fluorine gas.

The second patent outlines a similar reprocessing method that employs solid-gas separation. In this method, spent oxide fuel reacts with HF gas, converting uranium, plutonium, and most impurities into solid fluorides. The process is conducted in two stages, allowing for the separation of gaseous uranium and volatile impurities while keeping plutonium in a solid form. This method simplifies the reprocessing steps and enhances the purification of uranium and plutonium, further contributing to the safety and efficiency of nuclear reactors.
