A 440-day single-pass continuous-flow leaching experiment was conducted at LLNL from September 1980 to December 1981. The data obtained for only one-third of the experiment are presented. The laboratory and data analysis of the remaining portion is still in progress at this time and a second report will follow at the end of FY83. This report concerns itself with the study of PNL 76-68 glass beads interacting with crushed uranium flow basalt and a simulated basalt groundwater under controlled conditions of temperature (25/sup 0/C and 75/sup 0/C) and flow rate (1, 10, and 300 ml/day). The main purpose of the experiment was to determine the absorption on basalt of Pu, Np, and some of the stable elements such as B, Mo, U, and Cs, as they were leached from the glass beads. Results are presented, as incremental and cumulative leach rates and sorption rates have been calculated for Pu, Np, B, Mo and U. also sorption profiles as a function of temperature and flow rate are graphically shown for Pu, Np, and U.
