Title: The Innovations of Stephen A Fell

Introduction

Stephen A Fell is a notable inventor based in Preston, GB. He is recognized for his contributions to the field of nuclear chemistry, particularly in the production of uranium tetrafluoride. His innovative approach has led to advancements in the processing of uranium, which is crucial for various applications in the nuclear industry.

Latest Patents

Stephen A Fell holds a patent for the production of uranium tetrafluoride (UF4). In this process, uranic oxides, UO3 and U3O8, are dissolved in dilute sulphuric acid (H2SO4). Hydrofluoric acid (HF) is then added to produce a uranyl fluoride-sulphate solution. This solution is electrolytically reduced to form uranous fluoride-sulphate complexes. From these complexes, hydrated uranium tetrafluoride is precipitated by the addition of dilute HF at elevated temperatures, preferably above 90°C. The uranyl fluoride-sulphate solution can also be produced by dissolving uranyl fluoride in H2SO4 or from uranyl sulphate solutions derived from solvent extraction or ion exchange purification processes conditioned with HF.
