-
RCP-2-505, Revision 1, Operation and Calibration of Low Volume Air Samplers.
-
RCP-2-502, Operation and Calibration of the Staplex Type TFIA Air
.
Sampler.
The licensee used a low volume air sampler with a 0.45 micron "Millipore" I
type filter as their primary source to implement the air sampling program.
A calibration label was afixed to each air sampler pump which designated
!
the pump flow rate with a charcoal cartridge and/or filter paper. The l
air sampler pumps were calibrated over a 15-minute period with the average
flow rate being determined from 4 readings taken at 5-minute intervals.
This calibration was performed in the calibration facility where dust
levels were relatively constant.
Total air sample volume was then calculated j
by multiplying the sample flow rate by the time the sample r was operated.
l The inspector questioned the licensee representatives about the accuracy
'
of this method for measuring total air volume pass'ng through the filter.
Filter paper was observed which varied from a light gray to dark brown on i
air samples collected, indicating that the particulate loading also j
varied significantly between samples.
Fiiter paper loading directly i
effects the flow rate of the air sample pump. A licensee representative stated that they would review the air sampling program. (50-317/81-05-01)
No items of noncompliance were identified in this area.
