【 摘 要 】

Based on experimental studies with simulated and actual wastes, we recommend adopting the use of 0.1-micron pore-size, sintered stainless-steel filter elements within the design of the Salt Waste Processing Facility. Furthermore, adopting the smaller pore size elements for the Actinide Removal Process would result in a significant risk to the start-up schedule due to delays for buying, installing, and testing new equipment. The existing 0.5-micron pore-size filters will provide nearly equivalent service with no additional capital investment. Unless the planned filter test at Building 512-S fails to meet specifications, the project should proceed with the existing equipment, including spares. When the existing equipment reaches the end of the service life, management can consider replacement with the smaller pore-size elements. The laboratory studies indicate that use of the smaller pore size equipment will result in greater protection against particulate fines passing to downstream facilities while giving equivalent or superior processing rates than provided by the 0.5-micron elements.
