Emission Control Technology and Quality Assurance Needs at Uranium Milling Facilities (Includes Supporting Methods for Testing, Operating, and Maintaining Air Pollution Control Devices).

摘要

Pacific Northwest Laboratory, under contract to the U.S. Nuclear Regulatory Commission, conducted an investigation of particulate emission control devices for application to process exhausts at uranium milling facilities. The scope of this investigation included devices now in use, as well as those devices that have potential application for milling sites. This report presents the results of the study. Emission control devices are categorized and described, including high-efficiency and moderate-efficiency devices as well as other (some novel) devices useful in specific situations. Preoperational considerations discussed include selecting devices, instrumentation, and testing programs. Operational and maintenance considerations related to dry and wet removal processes are described. Quality assurance documents and topics are also discussed.
