In fact, the approach is widely applicable to many EM problems when there are significant uncertainties In the end state of the waste streams and technology development is needed for remediation. The approach involves the analysis of end state based remediation scenarios to highlight the technology needs to achieve specified goals.

. The committee believes that scenarios to achieve predestined end states for the waste are an effective framework In which to consider technology development needs for the Implementation of cleanup operations.

Since the Hanford tanks have been selected for an illustrative application of the committee's proposed methodology for identifying technology development needs, a brief description of these tanks follows. The Hanford taIlks contain components of the waste streams from the chemical separations processes and various radionuclide recovery processes that took place between 1943 and 1989.

This is followed in Chapter 3 by consideration of the Hanford Site tank waste remediation in terms of developing illustrative end states and functional flowsheets. These functional flowsheets and end states become the basis for assessing technology development needs of important function process steps selected by the committee.
