Title: Innovations in Nuclear Fuel Recycling by Patricia D. Paviet

Introduction

Patricia D. Paviet is an accomplished inventor based in North Potomac, MD (US). She has made significant contributions to the field of nuclear fuel recycling, particularly through her innovative patent related to the extraction of actinides from used nuclear fuel.

Latest Patents

Patricia holds a patent for the Reduction-oxidation of actinides extraction process (ROANEX). This invention pertains to a method that efficiently extracts actinides from used nuclear fuel in a single purification cycle. The process begins with the separation of fission products from the used nuclear fuel, which contains actinides such as Uranium (U), Americium (Am), Plutonium (Pu), Neptunium (Np), and Curium (Cm). The actinides are then reduced to their lowest oxidation states and subsequently oxidized to their highest oxidation states. The method allows for the separation of Uranium, Plutonium, and Neptunium into an organic phase solution, while Americium and Curium are directed into a nitrate solution. The actinides are further processed to form a mixed oxide fuel.

Career Highlights

Patricia is currently employed at the U.S. Department of Energy, where she continues to work on advancements in nuclear technology and fuel recycling. Her expertise in this area has positioned her as a key figure in the development of sustainable energy solutions.
