Fermi, No permanent / portable PING CAMs used for monitoring general areas. General area air monitoring done with portable CAMs (primarily AMS4 units, usually 13-15 in service during power operation, more during outages) are in service throughout the power block. Plant effluent HVAC stacks are monitored with Eberline SPINGs 3A / 4A.

We are now down to 2 SPINGs, one in each Penetration Area and have a project to replace them with similar particulate, Iodine, and noble gas monitors. This is just to sample the area atmosphere; it is not an effluent path monitor such as the P, I, and NG monitors on our auxiliary building plant vent. Bench Mark QUESTIONs: Has you plant ever used this type of full spectrum (P, I, NG) continuous air monitoring for an “area” of your plant? If yes, do you still have them, and what areas of the plant are you monitoring? If you still have them, are they the original instruments or have you replaced them?
