At Duke Energy we have 6 operating stations totaling 11 units (9 - PWR's and 2 -BWR's). We do not use the 4" high volume air samplers you describe. We do use the 2" high volume air samples (i.e. RADeCo H809Vi or equivalent). We have approximately 20 of these per unit. Most of these are calibrated and available for use at all times but during innage periods 1/2 of these are in storage. Additionally, we have Low Volume Continuous air samplers (i.e. RADeCo HD-29A or equivalent). We keep these calibrated and available for use in similar quantities to the high volume air samplers. As with the high volume air samplers, approximately 1/2 of these are in storage during innage periods. We also keep a small supply of both types at our central calibration facility to replace units broken beyond repair or meet additional special needs.

If yes - approximately how many do you typically keep in calibration and available for use during online operations?
