Description: Mixed (uranium-plutonium) oxide standards were prepared and utilized to qualify available nondestructive assay equipment (gamma spectrometers, neutron counters, and calorimeters). Equipment was evaluated during normal operation in a plutonium facility. Measured material balances were calculated for two separate fabrication campaigns. Plutonium material unaccounted for values of less than 0.5% based on the total throughput was obtained in the final balance. A special test was undertaken to compare the plutonium content of single pellets determined by available nondestructive assay methods with controlled potential coulometric values. The implications of both programs on safeguards are summarized. (auth)
