Progress on investigations to improve precision on mass spectrometric isotopic ratio measurements is reported. A detailed set of intructions as submitted to ASTM Committee C-26.05 on the rapid preparation and analysis of uranium and plutonium samples mass spectrometrically by the resin bead technique is also presented. This report contains information on two separate topics: one is a progress report on the International Safeguards Project Office A.82 in which we investigated various means of obtaining better precision on mass spectrometric isotopic ratio measurements. The idea investigated most thoroughly was the use of a two-filament source configuration on a pulse-counting mass spectrometer; our conclusion was that better results could be obtained with commercially available source systems. ORNL has purchased a turret source for evaluation on the two stage mass spectrometer. The second part of this report is a copy of the resin bead mass spectrometric procedure wd have submitted to ASTM for consideration for inclusion in their standard practice manual. This is a detailed, step-by-step description of uranium and plutonium sample preparation and analysis using the rapid bulk resin bead technique.
