This document describes the Hermex Process for Metal Decontamination by mercury processing. This process is a new method for decontaminating irradiated metals and purifying scrap virgin metals. The process as applied to irradiated uranium was listed in steps. Mercury appears to have many advantages as a metal reprocessing reagent which include the ability to dissolve, degrade, or amalgamate most metals, low melting and boiling points, radiation stability, and relative chemical inertness to nonoxidizing chemicals. A total of four runs were made to study the Hermex Process as applied to uranium metal, two using unirradiated uranium to perfect the equipment, and two with 3-year cooled X-10 slug samples. Figures and tables are included.
