Multiple-Relaxation-Time Lattice Boltzmann Model for Multiphase Flows in Three Dimensions

The production of plutonium at DOE’s Hanford Site during the cold war has resulted in millions of gallons of radioactive waste stored in various sites across the U.S. The waste exists in the liquid and solid form and kept in underground tanks some of which have been detected to leak due to the mechanical degradation and aging of the tank walls. The waste is being transferred to double shell tanks…

Advanced In-situ Instrumentation for HLW Tank Mixing and Retrieval

As the DOE’s Hanford site begins preparations for the transfer of high-level radioactive waste (HLW) from the double-shell tank s (DST) to the Waste Treatment and Immobilization Plant (WTP), the influence of waste feed consistency on the waste stabilization process – and final stabilized waste form – is currently under analysis. In order to characterize feed consistency prior to transfer, a suite of instrumentation will be required to monitor the…

Design and Development of Innovative High-Level Waste Pipeline Unplugging Technologies (Peristaltic Crawler)

The U.S. DOE Hanford site has the largest number of High-Level Waste (HLW) storage tanks and the largest volume of HLW in the United States. The safe storage, retrieval, treatment, and disposal of approximately 53 million gallons of highly toxic, high-level radioactive waste stored in Hanford’s 177 underground tanks are a national priority. Pipeline plugging has been cited as one of the major issues at can result in unplanned outages…

Design and Development of Innovative High-Level Waste Pipeline Unplugging Technologies (Asynchronous Pulsing)

Availability of pipeline unplugging technologies is critical to the effort of cross-site HLW transfers through pipelines. In the past,some of the pipelines have plugged resulting in schedule delays and increased costs. Furthermore, pipeline plugging has been cited as one of the major issues that can result in unplanned outages at the Hanford WTP, causing inconsistent operation. Currently, there are no unplugging technologies qualified to be deployed at the sites should…
