Rheological and Physical Properties of Hanford Radioactive LAW AZ-102 Pretreated Waste and Melter Feed

The purpose and objective of this task was to measure and report the physical and rheological properties, pH, and PSD of a radioactive Hanford tank sample, 241-AZ-102 pretreated by the reference RPP-WTP pretreatment process at SRTC. The LAW pretreated wastes and melter feeds were characterized at two different sodium molarities in accordance with RPP-WTP R and T guidelines for characterization. The initial AZ-102 pretreated waste was received at a concentration of 4.38M Na. This pretreated waste was then diluted to two different sodium molarities of 1.0M Na and 1.3M Na. After the 1.0M Na and 1.3M Na pretreated wastes were characterized, these waste streams were blended with the project approved GFCs to make melter feeds. The physical and rheological properties and pH of the resulting melter feeds were measured using the methods outlined in the RPP-WTP guidelines, unless otherwise stated in this document
