Processing of uranyl nitrate hexahydrate (UNH) at DOE`s Fernald Site: Success and pitfalls

PDF Version Also Available for Download.

Description

After 36 years of operation, uranium production at the Department of Energy Fernald Environmental Management Project (FEMP) was halted in 1989. Uranyl Nitrate Hexahydrate (UNH) had been produced during the uranium refining. In June 1991, DOE determined the UNH to be a mixed hazardous waste under the Resource Conservation and Recovery Act. A UNH Neutralization Project began processing UNH stored in stainless steel tanks located in various areas within the Fernald Plant 2/3 Complex. It was discovered that the valves, flanges, and other fittings of the UNH storage tanks were leaking. This made processing the UNH a high priority and ... continued below

It was discovered that the valves, flanges, and other fittings of the UNH storage tanks were leaking. This made processing the UNH a high priority and Comprehensive, Environmental, Response, Compensation, and Liability Act Removal Action No. 20, Stabilization of UNH Inventories, was initiated. This report presents the successes and pitfalls of the cleanup of UNH.
