Gamma techniques for IAEA (International Atomic Energy Agency) safeguards at centrifuge enrichment cascades

Conference · · Transactions of the American Nuclear Society; (USA)
OSTI ID:5626034
; ; ;
On February 4, 1983, the Hexapartite Safeguards Project (HSP) concluded that the safeguards approach involving limited frequency unannounced access (LFUA) by International Atomic Energy Agency (IAEA) inspectors to cascades areas together with inspection activities outside the cascade areas meets the IAEA safeguards objectives in an effective and efficient way. In this way, the risks of revealing sensitive information were also minimized. The approach has been defined clearly and unambiguously, and it should be applied equally to all technology holders. One of the conclusions of the HSP was that a nondestructive assay go/no-go technique should be used during the LFUA inspections in the cascade areas of centrifuge enrichment plants. The purpose is to verify that the enrichment of the product UF{sub 6} gas is in the range of low-enriched uranium (LEU), i.e., the enrichment is below 20%.
