“…Assuming little mixing, the PUREX cladding waste solids would be the top layer. Core analyses (Simpson et al 1993a(Simpson et al , 1993b suggest that mixing of the layers occurred.…”

“…Waste in C-112 was sampled first with cores 35 and 36 taken from near the inlet and core 34 taken from the opposite 2.2 side of the tank (Simpson et al 1993a). From C-109, cores 47 and 48 were taken from near the waste inlet, and core 49 was taken from the opposite side (Simpson et al 1993b). …”

“…The variability within the tank is different from that expected based on sampling location. Cores 47 and 48 were taken from areas in the tank near the inlet (Simpson et al 1993b) and would therefore be expected to be more similar to each other rather than to the waste from core 49, which was on the opposite side of the tank from the inlet. representative-news of the INFARM-2 simulant to the C-112 waste samples, the simulant is representative in terms of number of particles, having a particular diameter; however, in terms of volume fraction occupied, the simulant is not representative.…”

“…Possibilities include decomposition of Al(oH), as suggested by Simpson et al 1993b, melting with the simultaneous loss of waters of hydration, or perhaps solid transformation reactions and loss of water by stable hydrates. It is interesting that this endothermic reaction is near where exothermic behavior is observed for INFARM-2 simulant; this endotherm could mask any low-grade exothermic behavior.…”

This Critical Review reviews the origin and chemical and rheological complexity of radioactive waste at the U.S. Department of Energy Hanford Site. The waste, stored in underground tanks, was generated via three distinct processes over decades of plutonium extraction operations. Although close records were kept of original waste disposition, tank-to-tank transfers and conditions that impede equilibrium complicate our understanding of the chemistry, phase composition, and rheology of the waste. Tank waste slurries comprise particles and aggregates from nano to micro scales, with varying densities, morphologies, heterogeneous compositions, and complicated responses to flow regimes and process conditions. Further, remnant or changing radiation fields may affect the stability and rheology of the waste. These conditions pose challenges for transport through conduits or pipes to treatment plants for vitrification. Additionally, recalcitrant boehmite degrades glass quality and the high aluminum content must be reduced prior to vitrification for the manufacture of waste glass of acceptable durability. However, caustic leaching indicates that boehmite dissolves much more slowly than predicted given surface normalized rates. Existing empirical models based on ex situ experiments and observations generally only describe material balances and have not effectively predicted process performance. Recent advances in the areas of in situ microscopy, aberration-corrected transmission electron microscopy, theoretical modeling across scales, and experimental methods for probing the physics and chemistry at mineral-fluid and mineral-mineral interfaces are being implemented to build robustly predictive physics-based models.
