Research and development activities of the Waste Fixation Program for April through June 1976 are described. The objective of this program is to develop processes to convert high-level liquid waste (HLLW) from the light water reactor (LWR) fuel cycle to solid forms that are demonstrated to be physically, chemically, and radiolytically stable and inert. Several significant results were obtained during this report period. These are listed below and detailed in the text of this report. Tests of the spray calciner, fed with simulated Nuclear Fuel Services (NES) wastes, were successful. The joule-heated ceramic melter has operated continuously for more than 5 months in 1976 and for more than 16 months total. Since the last report over 2500 lb of simulated high-level waste glass have been produced while feeding dry powder calcine and slurried liquid waste. A report on water leaching at 25/sup 0/C of UO/sub 2/ fuel with an average burnup of 54,500 MWD/MTU is being issued. Fluidized bed waste calcine particles were monocoated with Al/sub 2/O/sub 3/ or duplex-coated with PyC--Al/sub 2/O/sub 3/ in a fluidized bed; larger calcine pellets were formed with a disk pelletizer and coated with Pyrex frit.
