Evaluation of THOR(tm) Mineralized Waste Forms (Granular and Monolith) for the DOE Advanced Remediation Technologies (ART) Phase 2 Project.

摘要

Fluidized Bed Steam Reforming (FBSR) processing of Hanford Low Activity Waste (LAW) and Waste Treatment Plant Secondary Waste (WTP-SW) simulants was performed in April/May 2008 by THOR Treatment Technologies LLC (TTT). The testing was performed at the Hazen Research Inc. (HRI) Engineering Scale Technology Demonstration (ESTD) pilot plant facilities in Golden, CO. FBSR products from these pilot tests on simulated waste representative of the Hanford LAW and the WTP-SW were subsequently transferred to the Savannah River National Laboratory (SRNL) for characterization, leach testing, and a monolith binder down selection. Initially, bed and fines samples consisting of four granular LAW as-received Product Receiver (PR) bed samples from the Denitration and Mineralization Reformer (DMR), four High Temperature Filter (HTF) fines, two granular WTP-SW as-received PR bed samples from the DMR and two HTF samples were received by SRNL. After the initial bed and fines samples had been received and testing commenced, SRNL received aggregate samples (blends of bed and fines that had been blended at HRI) of both LAW and WTP-SW. Only the aggregate blends were monolithed using a variety of different binders.
