The committee also briefly comments on the Office of Environmental Management (EM) tank technology development program and the impact on this program of such external factors as privatization.

In particular, an end state based approach that considers a range of plausible scenarios will identify technology gaps and technology development needs associated with credible alternative flowsheets. Implementing such an approach will also identify uncertainties and potential improvements to the existing baseline flowsheet, if it exists, that can lead to more desirable scenarios.

Recommendations An end state based approach to establishing an appropriate technology development program in support of DOE's environmental management program should be adopted. In particular, this approach should encompass reference end states for each waste stream, plus plausible alternative end states for each waste stream to accommodate uncertainty and potential future programmatic changes.

. Cost-risk studies should be more widely used in remediation decision making that forms the basis for technology development in an end state based approach.

Vitrifier Offgas Processing · The committee found no Hanford-designated technology needs identified by the Site Technology Coordination Groups for vitrification offgas processing, nor are there relevant projects evident in the Tank Focus Area program or elsewhere in DOE EM. The primary technology development needs relate to preventing radioactive and toxic wastes from leaving the vitrifies offgas and to preventing deleterious buildup of both radioactive and nonradioactive solids in the offgas system.

Alternative scenarios including defined end states should be formulated and evaluated, and technology development unique to these scenarios should be pursued on a basis that is pnoritized with the help of performance assessment results and additional knowledge from relevant scientific research. GENERAL FACTORS Conclusions Decision making related to technology needed for the remediation of high-level radioactive wastes in taIlks must consider factors other than purely scientific and technical.

From page 70... ...
· Given DOE's lack of experience In privatization of such major functions as research, development, and cleanup operations, the committee recommends parallel pursuit of technology development for an alternative to the current privatization strategy for the Hanford Tank Waste Remediation System. It is not considered prudent to rely totally on privatization to develop the required technologies for systems with the history and complexity of high-level radioactive waste in tanks.
