Development of HEPA filter retention-efficiency monitor
Technical Report
·
OSTI ID:5051365
This report documents the conceptual design, laboratory evaluation, and in-plant demonstration of a HEPA filter retention efficiency monitor. This monitor uses electrofluidized beds to quantitatively retain all radioactive aerosols penetrating a filter and uses NaI(Tl) detectors to measure the collected particles. Filter efficiencies greater than or equal to 99.95% can be measured when plant operations generate sufficient radioactive aerosols. The effects of both normal and abnormal operating conditions on the monitor are documented.
