Material control and accountability aspects of safeguards for the USA /sup 233/U/Th fuel recycle plant
The materials control and accountability aspects of the reprocessing and refabrication of a conceptual large-scale HTGR fuel recycle plant have been discussed. Two fuel cycles were considered. The traditional highly enriched uranium cycle uses an initial or makeup fuel element with a fissile enrichment of 93% /sup 235/U. The more recent medium enriched uranium cycle uses initial or makeup fuel elements with a fissile enrichment less than 20% /sup 235/U. In both cases, /sup 233/U bred from the fertile thorium is recycled. Materials control and accountability in the plant will be by means of a real-time accountability method. Accountability data will be derived from monitoring of total material mass through the processes and a system of numerous assays, both destructive and nondestructive. (6 figures, 3 tables)
