Abstract
To determine uranium and plutonium concentration using isotope dilution mass spectrometry, weighed aliquands of a synthetic mixture containing about 2mg of Pu (with a {sup 239}Pu abundance of about 98%) and 37mg of U (with a {sup 235}U enrichment of about 19%) have been prepared by the IAEA-SAL and verified by three analytical laboratories: NMCC-SAL, OEFZS, IAEA-SAL; they will be used to spike samples of concentrated spent fuel solutions with a high burnup and a low {sup 235}U enrichment. Certified Reference Materials Pu-NBL-126, natural U-NBL-112A and 93% enriched U-NBL-116 were used to prepare a stock solution containing about 3.2 mg/ml of Pu and 64.3 mg/ml of 18.7% enriched U. Before shipment to the Reprocessing Plant, aliquands of the stock solution are dried to give Large Size Dried (LSD) Spikes which resist shocks encountered during transportation, so that they can readily be recovered quantitatively at the plant. This paper describes the preparation and the validation of a fifth batch of LSD-spike which is intended to be used as a common spike by the plant operator, the national and the IAEA inspectorates. 7 refs, 6 tabs.
