CPNPP using older inventory of Siemens/Thermo EPDs in the manual mode with 
selected rate/dose set points.  PICs are available as additional backup and for 
fire brigade use.  On-site shepherd irradiator used for calibration of PICs/EDs.

Fermi - still using PICs in e-plan kits (cost factor for change). We calibrate 
PICs on site with panoramic / beam irradiators, depends on PIC range.

Duke Energy is looking to phase out Personal Ion Chambers in E-Plan kits, in 
favor of electronic dosimeters.

Has your site done this in the past?

Is there a point of contact we can reach out to to discuss 50.54(f) 
applicability?

If you maintain PICs in your E-Plan inventories, who are you using for 
calibration services?
