We have developed a new technique for simultaneously determining the plutonium concentration and the isotopic composition of highly irradiated fuel dissolver solutions, such as the input to a chemical reprocessing plant. This technique combines the high-resolution, low- energy, gamma-ray spectroscopy technique, the isotope dilution technique, and the resin head technique in one; it is referred to as isotope dilution gamma-ray spectroscopy (IDGS). The IDGS involves adding a well-characterized plutonium isotope to the unknown solution and then extracting the plutonium from the spiked (mixed) solution on resin beads and subsequently measuring the beads with high-resolution gamma-ray spectroscopy. The spike used in this experiment is a large size spike of {sup 239}Pu. The plutonium concentration of the dissolver solution obtained from the first IDGS measurement agrees with that obtained by isotope dilution mass spectrometry within 0. 042%. 4 refs., 4 figs., 4 tabs.
