The Los Alamos Scientific Laboratory contribution to the Waste Isolation Safety Assessment Program, Task 4, for the third quarter of FY-79 involved plutonium, americium, and uranium(VI) batch sorption studies. The technetium sorption ratio on tuff was not found to be dependent on technetium concentration. Studies of the behavior of plutonium and americium in aqueous solutions at pH approx. = 8 were continued. Studies of the sorption of strontium, cesium, barium, cerium, europium, uranium, and americium on salt dome materials were made under atmospheric and controlled atmosphere conditions. The first experiments to assess the dependence of sorption ratio on groundwater composition were started. Migration rate studies using crushed rock columns and fractured cores were continued. Additional chemical analyses were made, as were some studies of the sorption of plutonium and neptunium using a microautoradiographic technique.
