Title: The Innovations of Laurence Chareyre

Introduction

Laurence Chareyre is a notable inventor based in Saint Just D'Ardeche, France. She has made significant contributions to the field of nuclear fuel processing, holding 2 patents that focus on innovative methods for treating spent nuclear fuel.

Latest Patents

Chareyre's latest patents include a method for the treatment of an aqueous nitric solution resulting from dissolving spent nuclear fuel. This method is performed in a single cycle and does not require any operation involving reductive stripping of plutonium. Another patent details a method for the treatment of an aqueous solution resulting from the dissolution of spent nuclear fuel in nitric acid. This method allows for the extraction, separation, and decontamination of uranium and plutonium contained in the solution, also in a single cycle without reductive stripping of plutonium. The applications for these methods include the processing of uranium-based and/or plutonium-based spent nuclear fuels.

Additionally, she has developed a process for the grouped separation of actinides from a strongly acidic aqueous phase. This invention focuses on collectively separating all actinides (III), (IV), (V), and (VI) present in a strongly acidic aqueous phase from fission products, particularly lanthanides. The applications of this process are significant for the reprocessing of irradiated nuclear fuels, especially in recovering plutonium, neptunium, americium, curium, and possibly trace amounts of uranium.
