... The draft report describes the expert elicitation in Appendix F, which along with Section 3.3.1, pro vides information about the lines of inquiry and associated criteria used in the elicitation. The committee also suggests that the FFRDC consider a complete set of risks, including health risks and high-level legal issues, associated with shipping waste forms off the Hanford Site.

... , recommended practices." SCHEDULE ASSESSMENTS Given the importance of schedule as a reason for commissioning the FFRDC study and the increasing danger of tank leakage over time, schedule risk must be a central consideration.… The committee suggests that the FFRDC's forthcoming analysis examine the important interrelationships among technical and schedule risks as well as safety and costs. Page 26 of the draft report states that: "The effect [of project risks]

... If the funding profile remains flat, then the required facilities to perform System Plan 8 will not be available when required. Thus, the mission need for Supplemental LAW could change depending on the actual funding levels provided." REGULATORY COMPLIANCE ASSESSMENT The committee suggests that the FFRDC's analysis discuss what would be required for the non-vitrified waste forms being assessed to be considered "as good as glass" in the context of the current state of technology for waste forms other than glass from a technical and human health risk perspective.

... WASTE CONDITIONING AND SUPPLEMENTAL TREATMENT APPROACHES Regarding each of the primary treatment technologies, the committee suggests that the FFRDC clarify the relationship between the low-medium-high TRL levels used in the FFRDC draft report to the traditional nine-level TRL scale and the reason the traditional scale was not used. Of the technical appendixes on the three primary treatment alternatives, Appendix C on "Steam Re forming" provides a detailed discussion.

From page 47...
... • A complete and consistent set of supplemental treatment alternatives specifying clearly whether just the major three supplemental treatment approaches are being assessed or whether there are any variations on these three to consider, including the processing, transportation, and disposal options in each alternative. Likewise, the committee suggests that the FFRDC consider identifying and describing opportunities to improve the performance, cost, and rate of implementation of the alter natives through pre-treatment to disposal, even if some are strictly outside the scope of the SLAW facility.
