Modified resin-bead technique: its application to safeguards
The technique of using resin beads to acquire uranium and plutonium samples from radioactive solutions for mass spectrometric analysis has been modified to meet the realities of reprocessing plant operation. The time required for sample acquisition has been reduced to ten minutes, the risk of contamination has been greatly reduced, and the entire operation is made easier to execute in a hot cell. The viability of the resin bead-mass spectrometric technique for safeguards purposes has been demonstrated through various international verification experiments. Results from this technique agree very well with those obtained via conventional isotope dilution mass spectrometry. In conjunction with a quadrupole mass spectrometer mounted in a mobile laboratory, it has been evaluated as an on-site technique to obtain uranium concentrations. The resin bead has also been evaluated in conjunction with a mobile mass spectrometry laboratory for use as an on-site inspection device. The mobile laboratory is comprised of a quadrupole mass spectrometer and sample preparation equipment housed in a modified recreational vehicle.
