During the period January 1, 1976, through June 30, 1976, the following amounts of transuranium elements were recovered from ten irradiated HFIR targets: 2 g /sup 243/Am, 50 g /sup 244/Cm, 29 mg /sup 249/Bk, 277 mg /sup 252/Cf, 1.7 mg /sup 253/Es, and 0.5 pg /sup 257/Fm. About 50 mg of high-purity /sup 248/Cm was purified chemically for shipment, and another 75 mg of /sup 248/Cm was separated from /sup 252/Cf. Nineteen HFIR targets, each containing approximately 9 g of curium, were fabricated. There have been no changes during this report period in the chemical processing flowsheets normally used at TRU. Five neutron sources were fabricated, bringing the total fabricated to 84. Six sources that were used previously in various projects have been returned to TRU and are available for reassignment. Special projects included (1) the continued study of /sup 250/Cm production by irradiation of /sup 248/Cm; (2) the production of 0.54 mg of /sup 250/Cf by irradiation of /sup 249/Bk; (3) the separation of approximately 200 pg of /sup 254/Cf from 39-hr /sup 254m/Es that was produced by irradiation of 5 ..mu..g of /sup 253/Es; and (4) the determination of process steps needed to obtain rare-earth fission products in an oxide form from LiCl-based anion exchange raffinate solution.
