PCM's (beta/gamma portal monitors like a PCM1B or PCM2 or other): 15 During Outage, 11 Non outage
Gamma Portal Monitors (like a PM-7 or other): 7 Ion Chamber Dose Rate Survey Meter (e.g., Eberline RO2, RO2A; Bicron RSO5, RSO50) Beta,Gamma 11 High Range Ion Chamber Dose Rate Survey Meter (e.g., Eberline RO7) Gamma 2 Telescoping Dose Rate Survey Meter (e.g., Eberline 6112) Gamma 4 Contamination Survey Meter with End Window or Pancake GM Probe (e.g., Ludlum Model 177, Model 2) Beta, Gamma 24 Neutron Dose Rate Survey Meter (e.g., ASP-1/NRD) Neutron 2 Contamination Survey Meter with Scintillation Detector (e.g., Ludlum Model 3 with 43-5 probe) Alpha 2 These are the minimum number required to be on hand to meet our FSAR requirements. Normally we have additional numbers of instruments calibrated and ready to issue than the numbers provided above.

If you could give numbers for the listings below for your station that would be great. I will make the averages available for anyone interested. I don't need a probe breakdown or models, just approximate numbers (SWAG's OK).
