The focus of this study is the residual wastes that remained in a liquid Hanford Tank Waste specimen, designated, AP-105. The objective of this work is to determine the nature of the residual wastes, including composition and the possible identification of phases.
There were many iron-rich phases in the waste together with sodium salt phases. The iron-rich phases appeared to be Fe-Cr-Ni steel derived particles. Al-silicates were found and a wispy Cr oxide phase. Boehmite was also identified in the waste. There was evidence for the attachment of Si around the boehmite particles. Boehmite phases were found in close association with Cr-phases but iron was not co-located in these instances.
