Abstract
As part of the Consolidated Edison Uranium Solidification Program, a semicontinuous process has been developed for thermal denitration of concentrated liquid nitrate waste solutions containing radioactive uranium nuclides. Solids handling problems are minimized by feeding batches of the concentrated waste solution directly into a can that serves as the primary storage container. The solution is evaporated to dryness by careful, zone-controlled heating of the can inside a furnace, decomposing the nitrates and leaving a solid oxide residue. The can is then sealed before final storage. Processing problems of foaming, splattering, and line plugging have been eliminated through a significant process development study and equipment modifications.
