So far, samples have been taken by both Japan Government and the International Atomic Energy Agency (IAEA) from the feed accounting tank of the Reprocessing Plant. Upon transporting the samples, one A-type transport container per batch sample has been required. To simplify the transport of samples, the resin bead technique requiring the trace amounts of samples (several mg for uranium and for plutonium) has been developed with the Oak Ridge National Laboratory, USA being the center. This technique was introduced into the Power Reactor and Nuclear Fuel Development Corporation (PNC) as part of the TASTEX project, and then has been incorporated into the JASPAS project as one of the joint researches between the PNC and the IAEA, in which the PNC has played a leading role. Up to now, joint experiments have been performed seven times, and the resin bead technique may have reached a certain technical level with a few technical problems. In these joint experiments, the PNC prepared and transported samples, whereas the IAEA analysed them. In addition, the PNC has investigated the resin bead technique independently. As mentioned above, the most outstanding merit of the resin bead technique lies in the simplified transport of samples. The technique is also provided with another merit by which uranium and plutonium can be measured without separating them from each other, leading to the necessity of research and development of it on the part of the Reprocessing Plant. This paper describes the results of investigation on the measurement technique of uranium and plutonium by means of the resin bead technique, together with the results from the 3rd to 7th PNC-IAEA joint experiments.

An instrument based upon high-resolution $$gamma$$-ray measurements has beentested for more than 1 year at the TokaiReprocessing Facility for determinationof plutonium concentration by K-edge absorption densitometry and for determination of plutonium isotopic fractions bytransmission-corrected passive $$gamma$$-ray spectrometry. The nondestructive assay instrument was designed and built atLos Alamos National Laboratory for theTokai Advanced Safeguards Technology Exercise (TASTEX). It was used at Tokai forthe timely assay of more than 100 productsolution samples daring the TASTEX evaluations The results were compared tosolution samples during the TASTEXaluations. The results were compared toreference values obtained by conventionaldestructive analysis of these samples. The precision and accuracy of plutoniumconcentrations measured by the K-edgetechnique are shown to be with in 0.6% (1$$sigma$$) in these applications. The precisionsand accuracies of the isotopic fractions. determined by these passive
