Tank Wastes Planned for On-Site Disposal at Three Department of Energy Sites: The Savannah River Site - Interim Report MATERIAL AVAILABLE TO THE COMMITTEE The committee received more than 175 documents in the March-June 2005 period. Through the presentations listed above, DOE provided a wealth of information. However, most of this information was qualitative. For example, DOE presented a “discussion” of the performance assessment for the saltstone (Cook and Wilhite, 2005), rather than the actual performance assessment, which is not yet publicly available. The same applies to a qualitative discussion of the tank farm monitoring plans (Heffner and Wells, 2005). The committee did have some quantitative analyses available, such as the following: Draft salt waste determination and supporting documentation (DOE, 2005a) Performance assessment for Saltstone Vaults (Martin Marietta Energy Systems et al., 1994) Performance assessment for the closure of Tanks 17 and 20 (DOE, 1997a, 1997b) Environmental impact statement for tank waste closure (DOE, 2000) U.S. Nuclear Regulatory Commission tank closure determination for Tanks 17 and 20 (USNRC, 2000) DOE also made available to the committee a large number of technical reports on salt waste processing, bulk waste retrieval, heel removal, residual waste characterization, tank cleaning, and tank filling and closure. Most of the documents listed above were published before the new salt waste processing approach was proposed at the Savannah River Site in February 2005. Because of the significant differences in the new approach (e.g., significantly higher concentrations of cesium to be sent to saltstone with the deliquification, dissolution, and adjustment process, see Finding and Recommendation 2; and on-site disposal of waste from Tank 48, see Section II), the available information needs to be updated. Below are examples of information that the committee did not have and that it deems necessary to the fulfillment of its task. Examples of Committee’s Information Gaps The following are examples of pieces of information that the committee needs to determine whether DOE’s tank waste management plans slated for on-site disposal meet the performance objectives in Title 10 Part 61 of the Code of the Federal Regulations. This list is not meant to be exhaustive. Supplemental performance assessment calculations for the saltstone facility addressing the changes introduced with the Section 3116 salt waste determination and sensitivity studies. Response of disposal systems to extreme events (fires, floods). Performance assessments and environmental impact statement for tank farm closure (except tanks 17 and 20). Plans for annulus cleaning. Plans for deactivation and decommissioning of the piping within the tank farms-Plans for residual waste characterization. Revised Waste Acceptance Criteria for the saltstone vaults addressing the changes introduced with the Section 3116 salt waste determination-Support for

Tank Wastes Planned for On-Site Disposal at Three Department of Energy Sites: The Savannah River Site - Interim Report assumptions, estimate of levels of conservatisms, and sensitivity analyses for any calculation related to public health. Long-term monitoring plans. Estimates of worker doses for various steps and options for salt waste processing. Relative risks of various options for salt waste processing. Effectiveness of separations processes (i.e., efficiency in radionuclide removal) for the new salt waste processing approach. Risk assessment determining acceptable radionuclide concentrations (and/or inventories) and distributions that take into account measured and/or projected radionuclide concentrations, spatial variability of the concentrations, and attendant uncertainties (see Finding and Recommendation 3).
