Preconceptual Design Studies and Cost Data of Depleted Uranium Hexafluoride211 Conversion Plants

摘要

One of the more important legacies left with the Department of Energy (DOE) after211u001ethe privatization of the United States Enrichment Corporation is the large 211u001einventory of depleted uranium hexafluoride (DUF6). The current DUF6 program has 211u001elargely focused on the ongoing maintenance of the cylinders containing DUF6. The 211u001efirst step for future use or disposition is to convert the material, which 211u001erequires construction and long-term operation of one or more conversion plants. 211u001eThis report contains the final results from a preconceptual design study project. 211u001eIn this fast track, three month effort, Lawrence Livermore National Laboratory 211u001eand Bechtel National Incorporated developed and evaluated seven different 211u001epreconceptual design cases for a single plant. The preconceptual design, 211u001eschedules, costs, and issues associated with specified DUF6 conversion 211u001eapproaches, operating periods, and ownership options were evaluated based on 211u001ecriteria established by DOE. The single-plant conversion options studies were 211u001esimilar to the dry-conversion process alternatives from the PEIS. For each of the 211u001eseven cases considered, this report contains information on the conversion 211u001eprocess, preconceptual plant description, rough capital and operating costs, and 211u001epreliminary project schedule.
