【 摘 要 】

The processing rate of the Actinide Removal Project (ARP) is limited by the flow rate of the solid-liquid separation process. If the Department of Energy, DOE, could identify and develop a solid- liquid separation technology with a higher filter flux, they could increase the throughput of the Actinide Removal Project and complete treating that fraction of the waste stream in a shorter time, with a significant reduction in life-cycle cost. Savannah River Technology Center personnel identified the rotary microfilter as a technology that could significantly increase filter flux, with improvements of as much as 10X over the 0.5 micron crossflow filter and 5X over the 0.1 micron crossflow filter. The Savannah River Technology Center received funding from the DOE-HQ, Office of Cleanup Technologies, to evaluate and develop the rotary microfilter for radioactive service at the Savannah River Site. The authors performed pilot-scale simulant filtration tests with irradiated filter disks. They employed three types of filter disks for the tests (0.5 m stainless steel, 0.1 m stainless steel, and 0.1 m ceramic/stainless steel). They analyzed the filter's structural material, Ryton(R) for hardness, and irradiated the entire disk with an estimated 2.5-5 year (83-165 MRad) radiation dose. They measured the hardness of the Ryton(R) after the irradiation of the disk. Following irradiation, they placed the filters in the pilot-scale rotary microfilter unit and tested them with feed slurries containing 0.29 and 4.5 wt per cent solids.
