Solid Secondary Waste Data Package Supporting Hanford Integrated Disposal Facility Performance Assessment

“…The table also provides examples from other studies for information. Note that values for similar COPC from Cantrell et. al (2016) are not included due to the fundamental differences in the mixes considered.…”

“…This data package is focused on the information necessary to support the assessment of the SSW forms. A companion data package (Cantrell et al 2016) addresses the liquid secondary waste that will be disposed at IDF.…”

“…For analysis purposes, these waste streams were assumed to be representative of the ETF-generated SSW to be disposed at IDF 1 . These SSW resulting from ETF are addressed in Cantrell et al (2016). 1 Although leachate from the Mixed Waste Trench and other miscellaneous sources are planned for disposal at IDF as part of ETF SSW, the expected concentrations and associated volumes are assumed insignificant compared to the The current ETF treatment process is similar to the process that existed when the Tank Closure and Waste Management (TC&WM) EIS analysis was performed.…”

“…For that reason, parameter definitions and terms are carefully presented in this data package using conventions similar to Walton (1992). Note that an equally valid but different set of terms is used by Cantrell et al (2016). This SSW data package supports advective-diffusive transport of solutes in situations where chemical interactions can be reasonably approximated by linear instantaneous sorption and/or instantaneous solubility control.…”

Off-Gas Condensate and Cast Stone Analysis Results

“…To demonstrate that disposal requirements can be met, a representative secondary waste from the melter off-gas system was prepared for stabilization as a solid waste using the Cast Stone formulation (Cantrell et al 2016). Required chemical analyses were conducted to collect data on waste form performance to evaluate an opportunity to alter the recycling and develop a waste form that meets any disposal site waste acceptance criteria (WAC).…”
