Confirming LEU (Low-Enriched Uranium) in an LFUA (Limited-Frequency Unannounced Access) Environment

摘要

A standard sequential procedure is adapted to a limited-frequency unannounced access (LFUA) inspection problem, where uranium enrichment is monitored using nondestructive assay instrumentation. If the enrichment is in the low-enriched uranium (LEU) range, rapid confirmation to that effect is provided under anticipated measurement conditions. Decision thresholds are derived based on the required confidence level in an LEU confirmation. Also, the procedure is easily automated and is such that the raw data need not be revealed.
