The objective of this work is to determine the feasibility of adding metals to displace radioactive components from chelating organics that are present in Hanford tank waste. Parameters considered during this testing included operating time, metals concentration, operating temperature, hydroxide and ammonia concentrations, and chelating organic source. The metals evaluated in this testing included Fe(III), Cu(II) Ca(II), and Ni(II). The effects of metals addition upon the distribution of {sup 90}Sr, {sup 241}Am, and {sup 238,239,240}Pu as well as bulk metals between the supernatant and solid phases will be discussed. In addition, the simulant and actual waste test results will be compared.
