Single-Step Process to Treat the High Chloride Pu Inventory at the Plutonium Finishing Plant (PFP)

Abstract

The Plutonium Finishing Plant (PFP), operated by Fluor Hanford identified that up to 1000 items in their inventory contained high concentrations of chloride salts. This is problematic in that some of these salts are volatile at stabilization temperatures. At temperature (> 950OC) the molten salt is volatile and very corrosive to the furnace and off-gas system. Early testing at PFP indicated that the salt would deposit and plug the off-gas line. After stabilization, a sample of the material is processed through a Loss-on-Ignition (LOI) test. This test is intended to demonstrate that the stabilized material has
