Transuranium elements were obtained from 13 irradiated HFIR targets. One batch of high-purity /sup 248/Cm (approximately 75 mg) was separated from /sup 252/Cf. Eighteen shipments were made from TRU during the period. Seven HFIR targets, each containing 8 to 9 g of curium, were fabricated. A new scrubber system was installed in the dissolver off-gas (DOG) stream to remove the bulk of the /sup 131/I and to reduce the amount sorbed in the Hopcalite--charcoal system. During TRU target Campaign 53, the DOG stream was scrubbed with hyperazeotropic nitric acid (the IODOX process). Both the equipment and the process performed satisfactorily. Three neutron sources were fabricated during this report period, bringing the total fabricated to date to 100. Six sources were returned to TRU and are available for reassignment. Special projects included the production of several grams of ultrahigh-purity /sup 243/Am and the development of a method for purification of the ZnBr/sub 2/ solution from a shielding window. The values currently being used for transuranium element decay data and for cross-section data in planning irradiation-processing cycles, calculating production forecasts, and assaying products are tabulated.
