Title: Horace A. Friedman: Innovator in Nuclear Fuel Recovery
Introduction
Horace A. Friedman is a notable inventor based in Oak Ridge, TN (US). He has made significant contributions to the field of nuclear fuel recovery, holding 2 patents that showcase his innovative approaches to complex chemical processes.
Latest Patents
Friedman's latest patents include a method for the separation of uranium from technetium in the recovery of spent nuclear fuel. This method involves the addition of hydrazine to the product uranyl nitrate stream from the Purex process, which contains hexavalent uranium and heptavalent technetium. The technetium in the product stream is reduced and complexed by the addition of oxalic acid, allowing for the separation of the Tc-oxalate complex from uranium through solvent extraction with tributyl phosphate in n-dodecane. Another significant patent involves a method for selectively reducing plutonium values by photochemical means. This method enhances the rate of reduction of Pu(IV) to Pu(III) in nitric acid solution by exposing the solution to electromagnetic radiation, allowing for the preferential distribution of plutonium and uranium values.
